TORONTO, Jan. 18, 2022 (GLOBE NEWSWIRE) — Eloro Resources Ltd. (TSX-V: ELO; OTCQX: ELRRF; FSE: P2QM) (“Eloro”, or the “Company”) is pleased to provide an update on its Iska Iska silver-tin polymetallic project in the Potosi Department, southern Bolivia. By the end of 2021, the Company completed 40,468 metres (m) in 73 drill holes at Iska Iska, as shown in Figure 1. Table 1 summarizes drill holes with assays pending. Currently there are two surface drill rigs and one underground drill rig on site. Drilling with all rigs recommenced on January 17, 2022. Highlights of work in progress are as follows:

  • Definition drilling has been substantially completed over the Santa Barbara target zone which extends for over a strike length of approximately 1,400m, across a width of 500m and to a depth of 600+m. All drill holes in the Northwest Extension intersected significant mineralization confirming that the Santa Barbara mineralization extends across the full 1,400m long resource definition target zone. The mineralized system remains open along strike to the northwest and southeast as well as to the southwest.
  • More assay results are expected to be released in the next 2-3 weeks, but further delays have been experienced due to the impact of Covid-19 on staffing at the laboratories. All drill core completed prior to shutdown of drilling on December 17, 2021, has been logged, sawn and sampled with samples shipped to the laboratories.
  • The Iska Iska caldera complex, which we now know has both a main caldera and two nested secondary calderas, extends along strike in a northwest-southeast direction for at least 2.5km, a width of at least 2km and likely extends to a depth of more than 1km.
  • Going forward exploration drilling will be focused on testing the major targets in the Porco and Mina 2 areas along with the potential for a tin porphyry at depth. We are working closely with Micon International Limited to facilitate the National Instrument (“NI”) 43-101 mineral resource estimation process which we are now targeting to be completed in Q2 2022.

Tom Larsen, CEO of Eloro commented: “The last two years have proven to be Eloro’s most transformative and exciting to date. Our decision in 2019 to pursue a new mineral resource project, which resulted in the January 2020 signing of the Iska Iska silver-tin polymetallic property option agreement, has proven to be the catalyst for the Company’s upward trajectory and promising future. In just 15 months since the start of diamond drilling, Iska Iska has advanced from a promising grass roots project to being on the verge of outlining a significant NI 43-101 compliant mineral resource. Under the leadership of Dr. Osvaldo Arce, P. Geo., our in-country General Manager, and Dr. Bill Pearson, P, Geo., our Executive Vice President Exploration, we have built a very strong in-country technical team based in Tupiza, Bolivia. This team is supported by several excellent local contractors including Leduc Drilling who have completed more than 40,000 metres of diamond drilling since we started. As outlined in this update, we have a tremendous amount of work in progress, which will lead to the inaugural mineral resource, confirmation of metallurgical recoveries and drill-testing of more major targets in this remarkable mineralized system.”

Dr. Bill Pearson, P.Geo., Eloro’s Executive Vice President Exploration, added: “Work is progressing well on completing an updated geological model for the Santa Barbara Target Zone. The bore hole induced polarization (IP) survey results are being processed and the resulting 3D inverse model should help in determining the internal geometry of the deposit, especially of higher sulphide zones, which generally have the best grades. We are working closely with Micon International Limited to facilitate the mineral resource estimation process which we are now targeting to be completed in Q2 2022. Both the ALS and AHK Laboratories are working to reduce the backlog of samples waiting for analysis, however, the recent surge in Covid has created staffing issues for the laboratories, hence there may be further delays in receiving assay results although it is expected that more results will be available for release in the next 2-3 weeks. Definition drilling on our 1,400m by 500m wide by 600m deep mineral resource definition target zone in Santa Barbara is almost complete with the final two holes to be completed in the next two weeks. All drill core completed prior to shutdown of drilling on December 17, 2021 has been logged, sawn and sampled with samples shipped to the laboratories. Going forward exploration drilling will be focused on testing the major targets in the Porco and Mina 2 areas along with the potential for a tin porphyry at depth.”

Dr. Osvaldo Arce, P.Geo., General Manager of Eloro`s Bolivian subsidiary, Minera Tupiza S.R.L. (“Minera Tupiza”), said: “The Iska Iska silver-tin polymetallic deposit is hosted in Miocene breccia pipes, dacitic domes as well as granodiorite stocks and Ordovician sandstones, but especially in the breccia pipes. These breccia pipes were formed by explosive fluids derived from a large magmatic plumbing system, likely comparable to several major deposits in southern Bolivia. Such as Chorolque, Tasna, Tatasi, Chocaya and Siete Suyos. However, in contrast to these other deposits, the Iska Iska system shows a uniqueness of preservation due to the intense and ubiquitous silicification that affects all rocks but especially those with closer proximity to the vents marked by the breccia pipes. The basement Ordovician quartz sandstones are also very erosionally resistant. The combination of the silicification and erosionally resistant basement has preserved an almost complete volcanic edifice at Iska Iska which extends 1km vertically from the valley floor. We now know that the Iska Iska caldera complex consists of a large main caldera covering an area of approximately 1.6km by 1.8km with two nested secondary calderas approximately 1.2 km by 1.0 km in the northwest and approximately 800m in diameter in the southeast as shown in Figure 1. The Iska Iska caldera complex extends along strike in a northwest-southeast direction for at least 2.5km, a width of at least 2km and likely extends to a depth of more than 1km. Iska Iska was not discovered historically because of extensive leaching of metals at surface forming a very depleted oxide zone barren of metals.”

Definition Drilling Santa Barbara Target Area

Definition drilling in the Santa Barbara Mineral Resource Definition Drilling Target Area, as shown in Figure 1, has been substantially completed except for one section with holes DSB-26 and DSB-27 that will be drilled in the next few weeks. Overall, 25 surface (18,443m) and 19 underground (8,124m) holes totalling 26,567m have been completed to test the Santa Barbara target zone over a strike length of approximately 1,400m, across a width of 500m and to a depth of 600+m, as shown in Figure 1. The drill holes testing the Northwest Extension all intersected significant amounts of mineralization confirming that the Santa Barbara mineralization extends across the full 1,400m long target zone. Fill-in drilling from underground in the Santa Barbara adit also intersected significant mineralization and completed addition drill coverage in the eastern part of the SBBP. Assay results are pending for 22 of these mineral resource definition holes, as listed in Table 1.

An updated geological interpretation is in progress which will be used to refine the current model developed in Leapfrog mining software. The upper boundary of sulphide mineralization marked by the sulphide/oxide interface is well defined by geological logging and the magnetic susceptibility inversion model. The base of the mineralization, which is up to 600m thick, is defined by the lower limit of the high magnetic susceptibility. The northeast limit of the mineralization is defined by geology near the contact of the basement Ordovician quartz sandstones with the dacitic intrusive domes. The mineralized target zone is open along strike both to the northwest and southeast, as well as to the southwest. Data from the borehole IP inverse model is expected to aid in defining the internal geometry of the mineralization. Zones of higher sulphide content which have greater chargeability and much lower resistivity tend to be higher grade. These zones are also more magnetic because of the presence of pyrrhotite.

Exploration Drilling Porco Breccia Pipe, Gap Area and Mina 2 Targets

The focus of drilling in 2022 will shift to drill-testing the Porco Breccia Pipe (“PBP”) and the area between the PBP and Central Breccia Pipe (“CBP”) where there is a major magnetic anomaly (see press release October 21, 2021, and Figures 2 and 3), and testing the potential for a tin porphyry at depth. Figures 1 and 3 show the initial planned drilling. Holes DPC-07 and DPC-08, will initially test the Porco area targets with more follow-up drilling planned. Hole DM2-01, to be collared near the Mina 2 portal, will test for the potential tin porphyry at depth. In addition, an underground drill hole from the drill bay in the Santa Barbara adit, hole DSBU-07, will be drilled to the southwest to test the magnetic anomaly in the northern part of the CBP. Underground geological mapping and channel sampling is also in progress in the Mina 2 workings in the southern part of the property (see Figure 1 for location) with drilling also planned in this area later in the year. This area appears to be associated with a secondary caldera (Figure 1).

Eloro is currently using two laboratories, ALS Global and AHK Laboratories, both of whom have sample preparation facilities in Oruro, Bolivia and laboratories in Lima, Peru. The Company is also planning to use the ALS laboratory facility in Galway, Ireland, to achieve a faster turnaround and to help reduce the large backlog of samples with assays pending. Unfortunately, the recent wave of Covid-19 is impacting staffing at both ALS and AHK laboratories, hence there may be additional delays.

Metallurgical Drill Holes

Two diamond drill holes, METSBUG-01 and METSBUG-02 were drilled to provide larger samples of drill core for metallurgical testing. Hole MESTSBUG-01 was directed to intersect the mineralized breccia of the Santa Barbara Breccia Pipe (“SBBP”) near the centre of discovery hole DHK-15 which intersected 129.6 g Ag eq/t over 257.5m (see press release January 26, 2021). The second metallurgical hole, METSBUG-02, intersected the centre of hole DHK-18 in the mineralized envelope east of the SBBP. Hole DHK-18 returned 129.65 g Ag eq/t over 300.75m (see press release July 28, 2021). These holes have been sawn and one-quarter core sent for analysis with three-quarters core to be used for metallurgical testing.

Metallurgical Testing

A program of preliminary metallurgical testwork has been completed by the Mineral Concentration Laboratory of the National Faculty of Engineering of the Technical University of Oruro (UTO). The testwork used eight (8) composite samples assembled from early-stage resource definition drilling. These samples were selected to represent oxide and sulphide mineralization from the Huayra Kasa Mine (“HKM”) area, the SBBP and the CBP targets. Four of the samples were from HKM, three from SBBP and one from CBP. These early-stage drilling samples from these mineralized areas contained relatively low amounts of tin and therefore the conceptual testwork program was focussed on other valuable components particularly silver, zinc and lead.

The objective of this preliminary metallurgical testwork was to develop an early-stage conceptual understanding of the metallurgy. Although the program included basic mineralogy using X-ray diffraction (XRD) analysis, preliminary gravity and leach tests, and work index determinations, the main focus of the scoping level testwork program was to investigate froth flotation, without regrinding, to recover silver into separate lead and zinc concentrates. Detailed development work still needs to be done to investigate the recovery of tin, gold and other potentially valuable elements, such as indium, cadmium and bismuth.

Several open circuit flotation tests were completed using each composite sample and the results provided useful insight into the metallurgy of the Iska Iska project. The program was successful in providing a potential pathway to the successful recovery of lead, zinc and silver into saleable concentrates and will be used as a starting point for further metallurgical optimization during the next phase of testwork.

Richard Gowan, P.Eng., Principal Metallurgist for Micon International Limited, reviewed the preliminary open circuit flotation test results and considers that lead recovery of around 80% to 85% into a saleable lead concentrate could be expected once the flotation conditions were optimized. The projected zinc recovery to a final saleable zinc concentrate is around 80% to 90%. The lead concentrate would also contain considerable valuable silver and potentially payable amounts of gold, while the zinc concentrate would also contain payable amounts of silver and potentially valuable cadmium and indium. Total silver recoveries into the combined lead and silver rougher concentrates were around 73%, but with optimization Micon believes that the total flotation silver recovery can be increased up to 80%. Note that the projected recoveries based on the preliminary test data require confirmation from additional metallurgical testing hence should not be relied upon.

The next phase of testwork will be undertaken by Blue Coast Research Ltd. (“Blue Coast”) based in Parksville, BC and will optimize the flotation flowsheet to maximize lead, zinc, silver and gold into saleable concentrates and develop an appropriate flow sheet for the recovery of tin. Recovery of other more minor valuable metals including bismuth, indium and cadmium will also be considered. Blue Coast has world-class metallurgical testing, analytical services, flowsheet development, consulting and operational support. Their excellent team has been augmented with the addition of Mr. Mike Hallewell, C.Eng. a senior independent mineral processing consultant based in Cornwall, England, who has extensive specialist knowledge in the recovery of tin at mining operations and exploration projects worldwide.

Eloro, in consultation with Micon International Limited and Blue Coast, has selected four representative metallurgical samples from existing drill core in addition to the two new metallurgical holes: 1) Mineralized breccia in discovery drill hole DHK-15; 2) Mineralized dacitic envelope from hole DHK-15; 3) mineralized dacitic envelope from hole DHK-18 and 4) Sn-rich zone in hole DSB-06. Approximately 60m of core from each drill hole has been quarter cored. These samples, in addition to approximately 60m from the two metallurgical holes noted above (three-quarter core), are in the process of being shipped to Blue Coast with the testing likely to begin in the first part of February.

Bore Hole Induced Polarization Survey

The Bore Hole IP program at Iska Iska, carried out from August 2021 to December 2021, has progressed well with sixty-two (62) separate cross-hole surveys completed using many of the drill holes in the north-northeast part of the property. This program, which is being directed by Eloro’s Chief Geophysicist, Dr. Chris Hale, P.Geo., initially focused on the mineralization of the SBBP. A further nineteen (19) cross-hole surveys have also been completed to outline the PBP mineralization. In addition, forty (40) profiles have been obtained from twenty-one individual SBBP and PBP drill holes.

Two types of surveys have been carried out with two distinct objectives:

1. Pole Dipole surveys are used to profile the resistivity and chargeability of each drill hole, and

2. Cross-Hole surveys to test the continuity of mineralization between the drill holes.

In pole-dipole surveys current is injected into each hole being surveyed; one dipole length deeper than the lowest potential dipole. The current point changes throughout the survey as the entire array is lowered or raised in the drill hole.

For cross-hole surveys, current is injected at fixed points in several other drill holes around each candidate hole so that the sensitivity of the survey can be concentrated in the various volumes enclosed between different pairs of drill holes.

Low resistivity and high chargeability indicate the presence of metallic mineralization, in both survey types. Dipoles of 10, 25 and 50 m lengths were used to profile different cylinder radii around each drill hole and an additional potential was measured from the collar to depth. This provides a maximum off-hole measurement radius up to several hundred meters for the deepest stations. Profile data from the pole-dipole surveys calibrate the IP/Res response against the known mineralization in the drill core. Cross-hole data are used for inverse modelling with the UBC DCIP3D software and for interpretation of the off-hole distribution of mineralization.

The mineralization of the SBBP is being modeled using current injection from Santa Barbara and Huayra Kasa holes. PBP holes will provide a separate model of mineralization for the southern part of the property including the major target zone between the CBP and PBP.

Synchrotron Study

Synchrotron mineral cluster analysis was performed on 84 drill core samples by Dr. Lisa Van Loon of LisaCan Analytical Solutions and Dr. Neil Banerjee, P.Geo. of Western University, Department of Earth Science. These samples were selected to be representative of higher-grade areas of major and important minor metals including Ag, Sn, Zn, Pb, Au, Bi, In, Cu and Cd. This work builds on previous analytical work done on the underground channel samples from the due diligence program at Huayra Kasa (see press release June 25, 2020). The synchrotron is a type of circular particle accelerator that is an extremely powerful source of broad-spectrum electromagnetic radiation (e.g., visible light, infrared, UV, & X-rays), approximately 10 billion times brighter than the sun that provides a rapid, high-resolution analytical technique for mineral exploration.

Four (4) mineralogical domains were identified. These domains all have the same or very similar mineralogy. These mineralogical patterns are the result of the time-integrated effects of geological processes with the domains representing every event that has happened to these rocks since they were originally formed, including mineralization. Domain 2 is the largest and includes 60 samples while Domain 1 includes 17 samples, Domain 3 includes 6 samples, and Domain 4 consists of 1 sample. Within the 4 domains, Au-, Cd-, Cu-, Pb-, Sn, and Zn-dominant sub-domains are identified. The sub-domains are interpreted using the available geochemistry data to determine the predominant elements of interest within each sub-domain. These sub-domains can be used in a predictive way to better understand the spatial distribution of these elements of interest.

Domain 2 contains two Sn-dominant sub-domains. In one sub-domain Sn is associated with high Cu, Ag, Bi, and In. Cassiterite was positively identified as the Sn-bearing mineral. In the other sub-domain, Sn is associated with high Ag, but no Sn-bearing minerals were identified but this may reflect the limited number of samples (2) available in the second subdomain.

The sub-domains are interpreted to be likely related to variations in fluid composition, precipitation mechanism, or host rock interaction. The 3D distribution of the sub-domains will be evaluated in the context of lithological and structural variability within the deposit as they have important implications for geometallurgy and processing. Further work will investigate if these 3D subdomains can be used to identify blocks with different processing requirements. Additional testing is planned to further refine this pattern.

Enersoft Inc. GeologicAI Scanning Unit

Eloro has contracted Enersoft Inc. to provide a GeologicAI Scanning Unit on site in Tupiza to enable systematic scanning of diamond drill core. The GeologicAI unit has multiple scanners including XRF, Spectroscopy, 50xMicroscopic images and Laser Profilometer. The scanner, which is in a compact self-contained trailer, will provide real time processing of diamond drill core on-site. It will allow generation of mineral maps including distribution of sulphides of the polymetallic mineralization. Data from the synchrotron study will be used to help calibrate the AI to maximize its efficiency in generating these mineral maps which will be very helpful in defining metal and mineral zonation. The scanner is currently en route by boat to Bolivia and it is hoped that it will be on-site and fully operational by the end of February.

Environmental Studies

The following studies are being carried out by the environmental staff of Minera Tupiza SRL and environmental consultants at Iska Iska:

  • Collection of existing environmental documentation on the Porvenir concession, where the Iska Iska project is under exploration, including the review of environmental legal documents.
  • Environmental inspection and evaluation of the Porvenir concession.

About Iska Iska

Iska Iska silver-tin polymetallic project is a road accessible, royalty-free property, wholly controlled by the Title Holder, Empresa Minera Villegas S.R.L. and is located 48 km north of Tupiza city, in the Sud Chichas Province of the Department of Potosi in southern Bolivia. Eloro has an option to earn a 99% interest in Iska Iska.

Iska Iska is a major silver-tin polymetallic porphyry-epithermal complex associated with a Miocene possibly collapsed/resurgent caldera, emplaced on Ordovician age rocks with major breccia pipes, dacitic domes and hydrothermal breccias. The caldera is 1.6km by 1.8km in dimension with a vertical extent of at least 1km. Mineralization age is similar to Cerro Rico de Potosí and other major deposits such as San Vicente, Chorolque, Tasna and Tatasi located in the same geological trend.

Eloro began underground diamond drilling from the Huayra Kasa underground workings at Iska Iska on September 13, 2020. On November 18, 2020, Eloro announced the discovery of a significant breccia pipe with extensive silver polymetallic mineralization just east of the Huayra Kasa underground workings and a high-grade gold-bismuth zone in the underground workings. On November 24, 2020, Eloro announced the discovery of the SBBP approximately 150m southwest of the Huayra Kasa underground workings.

Subsequently, on January 26, 2021, Eloro announced significant results from the first drilling at the SBBP including the discovery hole DHK-15 which returned 129.60 g Ag eq/t over 257.5m (29.53g Ag/t, 0.078g Au/t, 1.45%Zn, 0.59%Pb, 0.080%Cu, 0.056%Sn, 0.0022%In and 0.0064% Bi from 0.0m to 257.5m. Subsequent drilling has confirmed significant values of Ag-Sn polymetallic mineralization in the SBBP and the adjacent CBP. A substantive mineralized envelope which is open along strike and down-dip extends around both major breccia pipes. Continuous channel sampling of the Santa Barbara Adit located to the east of SBBP returned 442 g Ag eq/t (164.96 g Ag/t, 0.46%Sn, 3.46% Pb and 0.14% Cu) over 166m including 1,092 g Ag eq/t (446 g Ag/t, 9.03% Pb and 1.16% Sn) over 56.19m. The west end of the adit intersects the end of the SBBP.

Since the discovery hole on the SBBP, Eloro has released a number of significant drill results on this target, including:

On May 4, 2021, Eloro released results from the first drill hole on the CBP. Hole DCN-01 intersected multiple mineralized intercepts including 196.09 g Ag eq/t (150.25 g Ag/t, 0.10% Sn and 0.05 g Au/t) over 56.2m and containing 342.98 g Ag eq/t (274.0 g Ag/t, 0.16% Sn and 0.16 g Au/t) over 27.53m.

Hole DCN-04 drilled at -80 degrees to the north from the northern radial platform of the CBP, intersected seventeen (17) mineralized intersections, principally Sn-Ag-bearing, over its 851.4m length. Best results include: 71.54 g Ag eq/t (32.58 g Ag/t and 0.10% Sn) over 97.10m from 134.40 to 231.5m; 101.52 g Ag eq/t (28.74 g Ag/t and 0.19% Sn) over 62.01m; 70.42 g Ag eq/t (28.74 g Ag/t and 0.16% Sn) over 22.59m; and 236.96 g Ag eq/t (92.21 g Ag/t and 0.25% Sn) over 17.45m. Hole DCS-02 was drilled southeast at -60 degrees from the south radial platform of the CBP. This hole, which was drilled to 800.5m, intersected nine (9) reportable Ag-Zn-Pb-Sn mineralized intervals. Best results include 79.53 g Ag eq/t (including 0.21% Sn) over 19.42m, 101.01 g Ag eq/t (32.76 g Ag/t, 0.76% Zn, 0.75% Pb) over 10.47 and 130.95g Ag eq/t (34.14 g Ag/t, 0.10 g Au/t, 1.35% Zn and 0.56 % Pb over 7.40m.

A detailed ground magnetic survey of the Iska Iska property, reported on June 6, 2021, confirmed the extent of the Iska Iska Caldera as determined from geological mapping and satellite interpretation, including Aster data. The SBBP and CBP, both of which have been confirmed by drill-testing, are marked by prominent low anomalies reflecting strong alteration. The magnetic data suggests that the Central and Porco Breccia Pipes likely merge at depth. In addition, there is a prominent area of low intensity magnetics northwest of the SBBP which was reported on in this press release.

Geological mapping and satellite interpretation identified a third major breccia pipe target, Porco (South), that is approximately 600m in diameter (South) located southeast of the CBP in the southern part of the Iska Iska caldera complex. The Porco (South) Breccia Pipe target has a similar magnetic signature to the Santa Barbara and Central Breccia Pipes, further confirming the likelihood of it being a major breccia pipe. Six (6) drill holes have been completed on Porco; assay results are pending. Previous channel sampling in the Porco adit located adjacent the target area 200m to the southeast returned 50m grading 519.35 g Ag eq/t including 236.13 g Ag/t, 1.89 g Au/t, 0.87% Cu, 0.22% Bi and >0.05% Sn over an average sample width of 2.49m.

Currently three diamond drill rigs are active at Iska Iska, two surface rigs and one underground drill. Planned drilling in the current program for Iska Iska is 51,000m of which 40,000m has been completed with the aim of outlining an initial inferred NI 43-101 compliant mineral resource by Q2 2022. The target zone at the SBBP and the surrounding mineralized envelope is 1400m along strike, 500m wide and extends to a depth of 600m. This zone is open along strike to the northwest and southeast as well as to the southwest. A borehole induced polarization/resistivity (IP/Res) survey is in progress to further define drill targets and aid resource definition drilling. Preliminary metallurgical tests are also in progress. An updated NI 43-101 Technical Report is being prepared by independent consultant Micon International Ltd.

TORONTO, Nov. 17, 2021 (GLOBE NEWSWIRE) — Eloro Resources Ltd. (TSX-V: ELO; OTCQX: ELRRF; FSE: P2QM) (“Eloro”, or the “Company”) is pleased to provide an update on its Iska Iska silver-tin polymetallic project in the Potosi Department, southern Bolivia. To date, the Company has completed 35,738 metres (m) in 68 drill holes including three (3) in progress to test major target areas at Iska Iska. This press release reports drilling results from one (1) additional hole which tested the Porco Breccia Pipe (“PBP”) (Hole DPC-01) and new underground channel sampling from the Porco adit located approximately 200m south of the PBP. Currently three drill rigs are in operation at Iska Iska. Two surface drill rigs are continuing to drill at the Santa Barbara Resource Definition Target Zone (Figure 1) to outline an initial National Instrument 43-101 (“NI-43-101”) compliant resource. A third drill, an underground rig, situated in the west end of the Santa Barbara Adit, is testing the eastern part of Santa Barbara Breccia Pipe (“SBBP’) and its mineralized envelope. Figure 1 is a geological plan map showing locations of drill holes completed, in progress and planned to complete resource definition drilling along with an updated geological interpretation. Figure 2 is a plan map of channel sampling at the Porco adit. Table 1 provides significant drilling results with definitions of chemical symbols, Table 2 details channel sample results from the Porco adit and Table 3 lists holes completed with assays pending, as well as holes in progress in the three major target areas. Highlights include:

Porco Adit

  • Channel sampling in the Porco adit returned 521.33 g Ag eq/t (including 117.10 g Ag/t, 1.44 g Au/t, 0.54% Cu and 0.66% Sn) over a 103m strike length with an average channel width of 1.8m as shown in Figure 2 and Table 2. Mineralization in the Porco adit is hosted in a series of veins, veinlets, stockworks and disseminations in Ordovician quartz sandstone. The veins are parallel to and crosscutting the drift. In the western part of the drift veins are primarily sulphide-bearing whereas those in the eastern half are primarily oxide. Eloro believes mineralization at the Porco adit is sourced from a large underlying porphyry system as evidenced by recently acquired magnetic susceptibility data.

Porco Breccia Pipe

  • Hole DCP-01 drilled due west at -65 degrees from the Porco radial platform intersected sixteen (16) separate zones of quartz-tourmaline veins in granodioritic intrusive breccia with best results of 110.30 g Ag eq/t over 3.0m, 67.08 g Ag eq/t over 6.0m including 168.25 g Ag eq/t (25.0 g Ag/t, 1.31% Zn, 0.32% Pb and 0.25% Sn) over 1.54m, 131.16 g Ag eq/t (18 g Ag/t, 0.54% Cu and 0.31% Bi) and 80.66 g Ag eq/t over 3.0m (0.23% Sn).

Figure 3 is a longitudinal section (A-A’ in Figure 1) showing the inverse model of magnetic susceptibility which highlights major targets and geological features. Figure 4 is a 3D view of the inversion model showing that Hole DPC-01 just clipped the edge of a very strong and extensive magnetic susceptibility anomaly below and to the northwest of the PBP. The strongest part of the anomaly, as shown in Figure 5, a cross section along drill hole DPC-01 (B-B’ in Figure 1), is located just to the northwest of this hole in the very prospective gap area between the Central Breccia Pipe and the PBP (see Figure 1). Further drilling is planned to test this target once definition drilling at the Santa Barbara Resource Definition Target Zone is completed.

Definition Drilling Santa Barbara Target Area

Definition drilling is continuing in the Santa Barbara Resource Definition Target Zone as shown in Figure 1. Currently a series of SW-NE sections at approximately 100m intervals are being completed with holes drilled on each section at -40 degrees and –65 degrees to provide coverage over the full target strike length of 1,400m. Underground drilling is continuing in the Santa Barbara adit to evaluate the resource potential in the mineralized envelope east of the SBBP. It is anticipated that the definition drilling program will be completed by early December. Drilling will then refocus on exploration of the major magnetic targets in the Central-Porco target area as outlined above.

Dr. Bill Pearson, P.Geo., Eloro’s Executive Vice President Exploration, added: “The magnetic data have proven invaluable in outlining the overall extent of the massive porphyry-epithermal system at Iska Iska. The higher-grade mineralized zones at Iska Iska tend to be magnetic hence the areas with high magnetic response are very prospective targets. Our geophysical team is also currently processing the downhole IP data from the Santa Barbara Resource Definition Target Zone which should help to better define the overall extent of mineralization especially zones with higher sulphide content which are generally higher grade.”

Dr. Osvaldo Arce, P.Geo., General Manager of Eloro`s Bolivian subsidiary, Minera Tupiza S.R.L. (“Minera Tupiza”), said: “The mineralization in the Porco adit is interpreted to be the lower part of the high sulphidation epithermal system which is likely connected to a major tin porphyry at depth as suggested by the extensive magnetic susceptibility anomaly. The intersections in Hole DPC-01 which are most abundant where this hole clipped the magnetic susceptibility anomaly are tin-rich supporting this conclusion. Our work continues to expand the remarkable mineralized system at Iska Iska which has now been shown to be at a district-scale.”

Dr. Quinton Hennigh, P.Geo., Eloro’s Senior Technical Advisor, commented: “The return of impressive polymetallic grades from the Porco adit confirm that the Iska Iska mineral system extends a remarkable 2.5 km from north to south. Metal endowments display notable zonation along this corridor from Ag-Zn-Pb-rich in the north to Ag-Sn-rich in the middle to Ag-Sn-Cu-Au-rich in the south. This is likely a reflection of proximity to the underlying source porphyry believed to be situated along the southern margin of the caldera complex as evidenced by recently collected magnetic data. The southern part of the Iska Iska system shows great potential for further discovery. It will be exciting to see drilling resume in this area.”

Note: True width of the mineralization is not known at the present time, but based on the current understanding of the relationship between drill orientation/inclination and the mineralization within the breccia pipes and the host rocks such as sandstones and dacites. It is estimated that true width ranges between 70% and 90% of the down hole interval length but this will be confirmed by further drilling. Percentage metal contents are shown for each element.

Chemical symbols: Ag= silver, Au = gold, Zn = zinc, Pb = lead, Cu = copper, Sn = tin, Bi = bismuth, Cd = cadmium and g Ag eq/t = grams silver equivalent per tonne. Quantities are given in percent (%) for Zn, Pb Cu, Sn, Bi and Cd and in grams per tonne (g/t) for Ag, Au and Ag eq.

Metal prices and conversion factors used for calculation of g Ag eq/t (grams Ag per grams x metal ratio) are as follows:

In calculating the intersections reported in this press release a sample cutoff of 30 g Ag eq/t was used with generally a maximum dilution of 3 continuous samples below cutoff included within a mineralized section unless more dilution is justified geologically.

The equivalent grade calculations are based on the stated metal prices and are provided for comparative purposes only, due to the polymetallic nature of the deposit. Preliminary metallurgical tests are in progress to establish levels of recovery for each element reported but currently the potential recovery for each element has not yet been established. While there is no assurance that all or any of the reported concentrations of metals will be recoverable, Bolivia has a long history of successfully mining and processing similar polymetallic deposits which is well documented in the landmark volume “Yacimientos Metaliferos de Bolivia” by Dr. Osvaldo R. Arce Burgoa, P.Geo.

Qualified Person

Dr. Osvaldo Arce, P. Geo., General Manager of Minera Tupiza, and a Qualified Person in the context of NI 43-101, has reviewed and approved the technical content of this news release. Dr. Bill Pearson, P.Geo., Executive Vice President Exploration Eloro, and who has more than 45 years of worldwide mining exploration experience including extensive work in South America, manages the overall technical program working closely with Dr. Arce. Dr. Quinton Hennigh, P.Geo., Senior Technical Advisor to Eloro and Independent Technical Advisor, Mr. Charley Murahwi P. Geo., FAusIMM of Micon International Limited are regularly consulted on technical aspects of the project.

Drill samples are prepared in ALS Bolivia Ltda’s preparation facility in Oruro, Bolivia with pulps sent to the main ALS Global laboratory in Lima for analysis. As announced in the February 26, 2021 press release, Eloro has changed the assay protocol to utilize X-ray fluorescence (XRF) to more accurately analyze higher tin. Tin in the CBP is suspected to occur as cassiterite which is insoluble in acid digestion, and therefore not suited for wet chemical techniques. In addition, other assay protocols have been changed to provide for a more accurate measurement of the wide-ranging suite of polymetallic metals at Iska Iska. Eloro employs an industry standard QA/QC program with standards, blanks and duplicates inserted into each batch of samples analyzed with selected check samples sent to a separate accredited laboratory.

Recently, AHK Laboratories, who manage a global network of laboratories have setup operations in Bolivia with the establishment of a preparation laboratory in Oruro. AHK has a strong base of accredited laboratories in South America including Peru, Chile, Brazil and Argentina. Eloro has contracted AHK to provide additional analytical services in order to help reduce the sample backlog. A series of check samples are currently being analyzed by AHK as a QA/QC check. AHK is following the same analytical protocols used as with ALS and with the same QA/QC protocols. The use of both accredited laboratories is reducing the backlog of samples to be analysed and improving turnaround.

The magnetic survey was carried out by MES Geophysics using a GEM Systems GSM-19W Overhauser magnetometer. Dr. Chris Hale, P.Geo. and Mr. John Gilliatt, P.Geo. of Intelligent Exploration provided the survey design, preparation of the maps and interpretation from data processed and quality reviewed by Rob McKeown, P. Geo. of MES Geophysics. Messrs. Hale, Gilliatt and McKeown are Qualified Persons as defined under NI 43-101. The 3D magnetic inversion model was prepared by Mr. Joe Mihelcic, P.Eng., P.Geo. of Clearview Geophysics in consultation with Messrs. Hale and Gilliatt. Mr. Mihelcic is a QP under NI 43-101.

About Iska Iska

Iska Iska silver-tin polymetallic project is a road accessible, royalty-free property, wholly controlled by the Title Holder, Empresa Minera Villegas S.R.L. and is located 48 km north of Tupiza city, in the Sud Chichas Province of the Department of Potosi in southern Bolivia. Eloro has an option to earn a 99% interest in Iska Iska.

Iska Iska is a major silver-tin polymetallic porphyry-epithermal complex associated with a Miocene possibly collapsed/resurgent caldera, emplaced on Ordovician age rocks with major breccia pipes, dacitic domes and hydrothermal breccias. The caldera is 1.6km by 1.8km in dimension with a vertical extent of at least 1km. Mineralization age is similar to Cerro Rico de Potosí and other major deposits such as San Vicente, Chorolque, Tasna and Tatasi located in the same geological trend.

Eloro began underground diamond drilling from the Huayra Kasa underground workings at Iska Iska on September 13, 2020. On November 18, 2020, Eloro announced the discovery of a significant breccia pipe with extensive silver polymetallic mineralization just east of the Huayra Kasa underground workings and a high-grade gold-bismuth zone in the underground workings. On November 24, 2020, Eloro announced the discovery of the SBBP approximately 150m southwest of the Huayra Kasa underground workings.

Subsequently, on January 26, 2021, Eloro announced significant results from the first drilling at the SBBP including the discovery hole DHK-15 which returned 129.60 g Ag eq/t over 257.5m (29.53g Ag/t, 0.078g Au/t, 1.45%Zn, 0.59%Pb, 0.080%Cu, 0.056%Sn, 0.0022%In and 0.0064% Bi from 0.0m to 257.5m. Subsequent drilling has confirmed significant values of Ag-Sn polymetallic mineralization in the SBBP and the adjacent CBP. A substantive mineralized envelope which is open along strike and down-dip extends around both major breccia pipes. Continuous channel sampling of the Santa Barbara Adit located to the east of SBBP returned 442 g Ag eq/t (164.96 g Ag/t, 0.46%Sn, 3.46% Pb and 0.14% Cu) over 166m including 1,092 g Ag eq/t (446 g Ag/t, 9.03% Pb and 1.16% Sn) over 56.19m. The west end of the adit intersects the end of the SBBP.

Since the discovery hole on the SBBP, Eloro has released a number of significant drill results on this target, including:

  • 122.66 grams g Ag eq/t (35.05 g Ag/t, 0.72% Zn, 0.61% Pb, 0.11% Sn and 0.06 g Au/t) over 123.61m including 205.74 g Ag eq/t (92.30 g Ag/t, 0.57% Zn, 0.85% Pb, 0.18% Sn and 0.07 g Au/t) over 32.32m (DSB-07),

On May 4, 2021, Eloro released results from the first drill hole on the CBP. Hole DCN-01 intersected multiple mineralized intercepts including 196.09 g Ag eq/t (150.25 g Ag/t, 0.10% Sn and 0.05 g Au/t) over 56.2m and containing 342.98 g Ag eq/t (274.0 g Ag/t, 0.16% Sn and 0.16 g Au/t) over 27.53m.

Hole DCN-04 drilled at -80 degrees to the north from the northern radial platform of the CBP, intersected seventeen (17) mineralized intersections, principally Sn-Ag-bearing, over its 851.4m length. Best results include: 71.54 g Ag eq/t (32.58 g Ag/t and 0.10% Sn) over 97.10m from 134.40 to 231.5m; 101.52 g Ag eq/t (28.74 g Ag/t and 0.19% Sn) over 62.01m; 70.42 g Ag eq/t (28.74 g Ag/t and 0.16% Sn) over 22.59m; and 236.96 g Ag eq/t (92.21 g Ag/t and 0.25% Sn) over 17.45m. Hole DCS-02 was drilled southeast at -60 degrees from the south radial platform of the CBP. This hole, which was drilled to 800.5m, intersected nine (9) reportable Ag-Zn-Pb-Sn mineralized intervals. Best results include 79.53 g Ag eq/t (including 0.21% Sn) over 19.42m, 101.01 g Ag eq/t (32.76 g Ag/t, 0.76% Zn, 0.75% Pb) over 10.47 and 130.95g Ag eq/t (34.14 g Ag/t, 0.10 g Au/t, 1.35% Zn and 0.56 % Pb over 7.40m.

A detailed ground magnetic survey of the Iska Iska property, reported on June 6, 2021, confirmed the extent of the Iska Iska Caldera as determined from geological mapping and satellite interpretation, including Aster data. The SBBP and CBP, both of which have been confirmed by drill-testing, are marked by prominent low anomalies reflecting strong alteration. The magnetic data suggests that the Central and Porco Breccia Pipes likely merge at depth. In addition, there is a prominent area of low intensity magnetics northwest of the SBBP which was reported on in this press release.

Geological mapping and satellite interpretation identified a third major breccia pipe target, Porco (South), that is approximately 600m in diameter (South) located southeast of the CBP in the southern part of the Iska Iska caldera complex. The Porco (South) Breccia Pipe target has a similar magnetic signature to the Santa Barbara and Central Breccia Pipes, further confirming the likelihood of it being a major breccia pipe. Six (6) drill holes have been completed on Porco; assay results are pending. Previous channel sampling in the Porco adit located adjacent the target area 200m to the southeast returned 50m grading 519.35 g Ag eq/t including 236.13 g Ag/t, 1.89 g Au/t, 0.87% Cu, 0.22% Bi and >0.05% Sn over an average sample width of 2.49m.

Currently three diamond drill rigs are active at Iska Iska, two surface rigs and one underground drill. Planned drilling for 2021 is 51,000m with the aim of outlining an initial inferred NI 43-101 compliant mineral resource by Q1 2022. The target zone at the SBBP and the surrounding mineralized envelope is 1400m along strike, 500m wide and extends to a depth of 600m. This zone is open along strike to the northwest and southeast. A downhole induced polarization/resistivity (IP/Res) survey is in progress to further define drill targets and aid resource definition drilling. Preliminary metallurgical tests are also in progress. An updated NI 43-101 Technical Report is being prepared by independent consultant Micon International Ltd.

Eloro Hits Bigly

Nov 3, 2021

The last time I talked to Tom Larsen of Eloro, the company had 8,000 assays outstanding. They can look at the core and know they are in mineralization but don’t have hard numbers. Progress on the assays are being made and they are down to 3,000 assays outstanding.

On November 2, 2021 Eloro put out a press release again showing outstanding numbers. They highlighted 188.5 meters of 100 g/t Ag eq/t consisting of 38.71 g/t Ag, 0.88% Zn and 0.51% Pb. That’s one of the longer holes and contains $72 rock over an incredible length.

Within that 188 meter hole there was a higher-grade interval of 65.8 meters of 75.51 g/t Ag with 0.16% Cu, 0.65% Pb and 0.96% Zn worth an interesting $122 USD per tonne.

In another hole they showed 224.92 g/t Ag eq over 7.42 meters. In that hole they showed 0.55% Sn (tin). They are using an absurdly low price for tin. Currently, 5.5 kilos of tin is worth $212 all by itself.

When the dust has settled and the assay labs get caught up and ELO has a dozen drill rigs turning on Iska Iska, they are almost certainly going to show over 2 billion tonnes of $100 rock. This is one of the best stories in the last twenty years. It is still way below the radar screen of most investors even with an absurd market cap today of about $225 million CAD.

Eloro has one of the highest caliber technical teams in South America and brilliant management. The stock was $.15 in March of 2020 only twenty months ago. When the market wakes up, it is going a lot higher.

Eloro is an advertiser. I have participated in several private placements in the past and bought shares in the open market. I am naturally biased so do your own due diligence.

TORONTO, Nov. 02, 2021 (GLOBE NEWSWIRE) — Eloro Resources Ltd. (TSX-V: ELO; OTCQX: ELRRF; FSE: P2QM) (“Eloro”, or the “Company”) is pleased to provide an update on its Iska Iska silver-tin polymetallic project in the Potosi Department, southern Bolivia. To date, the Company has completed 34,409 metres (m) in 64 drill holes including three (3) in progress to test major target areas at Iska Iska. This press release reports drilling results from one (1) additional hole which tested the Santa Barbara Breccia Pipe (“SBBP”) (Hole DHK-23) and two holes (DCN-05 and DCS-03) which tested the Central Breccia Pipe target (“CBP”). To date, every drill hole that has been assayed has returned multiple reportable mineralized intercepts. Currently three drill rigs are in operation at Iska Iska. Two surface drill rigs are continuing to drill at SBBP to outline an initial National Instrument 43-101 (“NI-43-101”) compliant resource. A third drill, an underground rig, situated in the west end of the Santa Barbara Adit, is testing the eastern part of SBBP and its mineralized envelope. Figure 1 is a geological plan map showing locations of drill holes and an updated geological interpretation. Table 1 provides significant drilling results with definitions of chemical symbols and Table 2 lists holes completed with assays pending, as well as holes in progress in the three major target areas. Highlights are as follows:

  • Hole DCS-03 drilled southwest at -60 degrees from the south radial platform of the CBP intersected twelve (12) separate zones of quartz-tourmaline veins in granodioritic intrusive breccia with best results of 224.92 g Ag eq/t (including 25.36 g Ag/t, 0.12 g Au/t and 0.55% Sn) over 7.42m and 113.67 g Ag eq/t (including 17.85 g Ag/t, 0.085 g Au/t, 0.21% Cu and 0.18% Sn) over 12.03m
  • Hole DCN-05 drilled due east at -60 degrees from the north radial platform of the CBP intersected ten (10) separate zones of quartz-tourmaline veins in granodioritic intrusive breccia with a best result of 104.72 g Ag eq/t (including 74.41 g Ag/t and 0.22% Cu) over 4.59m

Mr. Tom Larsen, CEO of Eloro, commented: “We are now starting to see a reduction in the backlog of assay samples with two laboratories operating at near capacity. These latest drill results, especially from DHK-23, are again demonstrating the accumulating amount of potential commercial bulk tonnage material, especially within the Santa Barbara complex, a subset of the overall Iska Iska volcanic edifice.”

Dr. Bill Pearson, P.Geo., Eloro’s Executive Vice President Exploration, added: “Mineral resource definition drilling is continuing in the Santa Barbara Target area, which is 1,400m along strike, 500m wide and extends to a depth of 600m. This target is open along strike to the northwest and southeast. Data from the downhole Induced Polarization survey is being processed and the resulting 3D inversion models should aid in refining our geological model, especially determining the likely geometry of the higher-grade zones that typically have greater sulphide content.”

Dr. Osvaldo Arce, P.Geo., General Manager of Eloro`s Bolivian subsidiary, Minera Tupiza S.R.L. (“Minera Tupiza”), said: “As we move to the northwest in the SBBP, silver and gold values are increasing suggesting that there is a zonation at Iska Iska, from a more tin-rich polymetallic mineralization in the southeastern part of the SBBP to more of a silver-rich polymetallic mineralization in the northwestern part. In addition, significant enriched tin-silver mineralization occurs in the northern part of the CBP.”

Note: True width of the mineralization is not known at the present time, but based on the current understanding of the relationship between drill orientation/inclination and the mineralization within the breccia pipes and the host rocks such as sandstones and dacites. It is estimated that true width ranges between 70% and 90% of the down hole interval length but this will be confirmed by further drilling. Percentage metal contents are shown for each element.

Chemical symbols: Ag= silver, Au = gold, Zn = zinc, Pb = lead, Cu = copper, Sn = tin, Bi = bismuth, Cd = cadmium and g Ag eq/t = grams silver equivalent per tonne. Quantities are given in percent (%) for Zn, Pb Cu, Sn, Bi and Cd and in grams per tonne (g/t) for Ag, Au and Ag eq.

Metal prices and conversion factors used for calculation of g Ag eq/t (grams Ag per grams x metal ratio) are as follows:

In calculating the intersections reported in this press release a sample cutoff of 30 g Ag eq/t was used with generally a maximum dilution of 3 continuous samples below cutoff included within a mineralized section unless more dilution is justified geologically.

The equivalent grade calculations are based on the stated metal prices and are provided for comparative purposes only, due to the polymetallic nature of the deposit. Preliminary metallurgical tests are in progress to establish levels of recovery for each element reported but currently the potential recovery for each element has not yet been established. While there is no assurance that all or any of the reported concentrations of metals will be recoverable, Bolivia has a long history of successfully mining and processing similar polymetallic deposits which is well documented in the landmark volume “Yacimientos Metaliferos de Bolivia” by Dr. Osvaldo R. Arce Burgoa, P.Geo.

Qualified Person

Dr. Osvaldo Arce, P. Geo., General Manager of Minera Tupiza, and a Qualified Person in the context of NI 43-101, has reviewed and approved the technical content of this news release. Dr. Bill Pearson, P.Geo., Executive Vice President Exploration Eloro, and who has more than 45 years of worldwide mining exploration experience including extensive work in South America, manages the overall technical program working closely with Dr. Arce. Dr. Quinton Hennigh, P.Geo., Senior Technical Advisor to Eloro and Independent Technical Advisor, Mr. Charley Murahwi P. Geo., FAusIMM of Micon International Limited are regularly consulted on technical aspects of the project.

Drill samples are prepared in ALS Bolivia Ltda’s preparation facility in Oruro, Bolivia with pulps sent to the main ALS Global laboratory in Lima for analysis. As announced in the February 26, 2021 press release, Eloro has changed the assay protocol to utilize X-ray fluorescence (XRF) to more accurately analyze higher tin. Tin in the CBP is suspected to occur as cassiterite which is insoluble in acid digestion, and therefore not suited for wet chemical techniques. In addition, other assay protocols have been changed to provide for a more accurate measurement of the wide-ranging suite of polymetallic metals at Iska Iska. Eloro employs an industry standard QA/QC program with standards, blanks and duplicates inserted into each batch of samples analyzed with selected check samples sent to a separate accredited laboratory.

Recently, AHK Laboratories, who manage a global network of laboratories have setup operations in Bolivia with the establishment of a preparation laboratory in Oruro. AHK has a strong base of accredited laboratories in South America including Peru, Chile, Brazil and Argentina. Eloro has contracted AHK to provide additional analytical services in order to help reduce the sample backlog. A series of check samples are currently being analyzed by AHK as a QA/QC check. AHK is following the same analytical protocols used as with ALS and with the same QA/QC protocols. The used of both accredited laboratories is reducing the backlog of samples to be analysed and improving turnaround.

About Iska Iska

Iska Iska silver-tin polymetallic project is a road accessible, royalty-free property, wholly-controlled by the Title Holder, Empresa Minera Villegas S.R.L. and is located 48 km north of Tupiza city, in the Sud Chichas Province of the Department of Potosi in southern Bolivia. Eloro has an option to earn a 99% interest in Iska Iska.

Iska Iska is a major silver-tin polymetallic porphyry-epithermal complex associated with a Miocene possibly collapsed/resurgent caldera, emplaced on Ordovician age rocks with major breccia pipes, dacitic domes and hydrothermal breccias. The caldera is 1.6km by 1.8km in dimension with a vertical extent of at least 1km. Mineralization age is similar to Cerro Rico de Potosí and other major deposits such as San Vicente, Chorolque, Tasna and Tatasi located in the same geological trend.

Eloro began underground diamond drilling from the Huayra Kasa underground workings at Iska Iska on September 13, 2020. On November 18, 2020 Eloro announced the discovery of a significant breccia pipe with extensive silver polymetallic mineralization just east of the Huayra Kasa underground workings and a high-grade gold-bismuth zone in the underground workings. On November 24, 2020, Eloro announced the discovery of the SBBP approximately 150m southwest of the Huayra Kasa underground workings.

Subsequently, on January 26, 2021, Eloro announced significant results from the first drilling at the SBBP including the discovery hole DHK-15 which returned 129.60 g Ag eq/t over 257.5m (29.53g Ag/t, 0.078g Au/t, 1.45%Zn, 0.59%Pb, 0.080%Cu, 0.056%Sn, 0.0022%In and 0.0064% Bi from 0.0m to 257.5m. Subsequent drilling has confirmed significant values of Ag-Sn polymetallic mineralization in the SBBP and the adjacent CBP. A substantive mineralized envelope which is open along strike and down-dip extends around both major breccia pipes. Continuous channel sampling of the Santa Barbara Adit located to the east of SBBP returned 442 g Ag eq/t (164.96 g Ag/t, 0.46%Sn, 3.46% Pb and 0.14% Cu) over 166m including 1,092 g Ag eq/t (446 g Ag/t, 9.03% Pb and 1.16% Sn) over 56.19m. The west end of the adit intersects the end of the SBBP.

Since the discovery hole on the SBBP, Eloro has released a number of significant drill results on this target, including:

  • 122.66 grams g Ag eq/t (35.05 g Ag/t, 0.72% Zn, 0.61% Pb, 0.11% Sn and 0.06 g Au/t) over 123.61m including 205.74 g Ag eq/t (92.30 g Ag/t, 0.57% Zn, 0.85% Pb, 0.18% Sn and 0.07 g Au/t) over 32.32m (DSB-07),

On May 4, 2021, Eloro released results from the first drill hole on the CBP. Hole DCN-01 intersected multiple mineralized intercepts including 196.09 g Ag eq/t (150.25 g Ag/t, 0.10% Sn and 0.05 g Au/t) over 56.2m and containing 342.98 g Ag eq/t (274.0 g Ag/t, 0.16% Sn and 0.16 g Au/t) over 27.53m.

Hole DCN-04 drilled at -80 degrees to the north from the northern radial platform of the CBP, intersected seventeen (17) mineralized intersections, principally Sn-Ag-bearing, over its 851.4m length. Best results include: 71.54 g Ag eq/t (32.58 g Ag/t and 0.10% Sn) over 97.10m from 134.40 to 231.5m; 101.52 g Ag eq/t (28.74 g Ag/t and 0.19% Sn) over 62.01m; 70.42 g Ag eq/t (28.74 g Ag/t and 0.16% Sn) over 22.59m; and 236.96 g Ag eq/t (92.21 g Ag/t and 0.25% Sn) over 17.45m. Hole DCS-02 was drilled southeast at -60 degrees from the south radial platform of the CBP. This hole, which was drilled to 800.5m, intersected nine (9) reportable Ag-Zn-Pb-Sn mineralized intervals. Best results include 79.53 g Ag eq/t (including 0.21% Sn) over 19.42m, 101.01 g Ag eq/t (32.76 g Ag/t, 0.76% Zn, 0.75% Pb) over 10.47 and 130.95g Ag eq/t (34.14 g Ag/t, 0.10 g Au/t, 1.35% Zn and 0.56 % Pb over 7.40m.

A detailed ground magnetic survey of the Iska Iska property, reported on June 6, 2021, confirmed the extent of the Iska Iska Caldera as determined from geological mapping and satellite interpretation, including Aster data. The SBBP and CBP, both of which have been confirmed by drill-testing, are marked by prominent low anomalies reflecting strong alteration. The magnetic data suggests that the Central and Porco Breccia Pipes likely merge at depth. In addition, there is a prominent area of low intensity magnetics northwest of the SBBP which was reported on in this press release.

Geological mapping and satellite interpretation identified a third major breccia pipe target, Porco (South), that is approximately 600m in diameter (South) located southeast of the CBP in the southern part of the Iska Iska caldera complex. The Porco (South) Breccia Pipe target has a similar magnetic signature to the Santa Barbara and Central Breccia Pipes, further confirming the likelihood of it being a major breccia pipe. Six (6) drill holes have been completed on Porco; assay results are pending. Previous channel sampling in the Porco adit located adjacent the target area 200m to the southeast returned 50m grading 519.35 g Ag eq/t including 236.13 g Ag/t, 1.89 g Au/t, 0.87% Cu, 0.22% Bi and >0.05% Sn over an average sample width of 2.49m.

Currently three diamond drill rigs are active at Iska Iska, two surface rigs and one underground drill. Planned drilling for 2021 is 51,000m with the aim of outlining an initial inferred NI 43-101 compliant mineral resource by Q1 2022. The target zone at the SBBP and the surrounding mineralized envelope is 1400m along strike, 500m wide and extends to a depth of 600m. This zone is open along strike to the northwest and southeast. A downhole induced polarization/resistivity (IP/Res) survey is in progress to further define drill targets and aid resource definition drilling. Preliminary metallurgical tests are also in progress. An updated NI 43-101 Technical Report is being prepared by independent consultant Micon International Ltd.

TORONTO, Sept. 28, 2021 (GLOBE NEWSWIRE) — Eloro Resources Ltd. (TSX-V: ELO; OTCQX: ELRRF; FSE: P2QM) (“Eloro”, or the “Company”) is pleased to provide an update on its Iska Iska silver-tin polymetallic project in the Potosi Department, southern Bolivia. To date, the Company has completed 30,014 metres (m) in 57 drill holes including three (3) in progress to test major target areas at Iska Iska. This press release reports drilling results from two (2) additional holes which tested the Santa Barbara Breccia Pipe (“SBBP”) (Holes DHK-21 and DHK-22). To date, every drill hole that has been assayed has returned multiple reportable mineralized intercepts. Currently three drill rigs are in operation at Iska Iska. Two surface drill rigs are completing drilling at SBBP in order to outline an initial National Instrument 43-101 (“NI 43-101”) compliant resource. A third drill, an underground rig, situated in the west end of the Santa Barbara Adit, is testing the eastern part of the SBBP and its mineralized envelope. Figure 1 is a geological plan map showing locations of drill holes and an updated geological interpretation. This map depicts the recently identified robust magnetic anomaly to the northwest of the SBBP where drilling is in progress (see press release June 7, 2021, for an overview of the magnetic results). Figure 2 is a north-south section showing the major potential extension of the SBBP mineralized system. Table 1 provides significant drilling results with definitions of chemical symbols and Table 2 lists holes completed with assays pending, as well as holes in progress in the three major target areas. Highlights are as follows:

Highlights:

  • 160.22 g Ag eq/t (36.53 g Ag/t, 1.63% Zn, 1.20% Pb and 0.10% Sn) over 194.14m from 168.85m to 362.99m in hole DHK-21, drilled from the west end of the Huayra Kasa underground workings at -70 degrees on section with discovery hole DHK-15, which intersected 129.60 g Ag eq/t over 257.5m (see press release dated January 26, 2021, and Figure 2). This intersection in Hole DHK-21 includes higher grade portions of:
    • 250.50 g Ag eq/t (51.31 g Ag/t, 3.35% Zn, 1.78% Pb and 0.10% Sn) over 18.24m from 238.21 to 256.45m;
    • 257.40 g Ag eq/t (75.83 g Ag/t, 2.29% Zn, 2.40% Pb and 0.12% Sn) over 16.33m from 283.57 to 299.90m; and
    • 350.91 g Ag eq/t (112.57 g Ag/t, 1.41% Zn, 3.08% Pb and 0.33% Sn) over 30.06m from 308.90 to 338.96m.
    • 64% of this 512.9m long hole contains reportable intersections
  • 94.68 g Ag eq/t (3.87 g Ag/t, 0.067 g Au/t, 1.63% Zn, 0.43% Pb and 0.05% Sn) over 169.93m from 124.66m to 294.59m in hole DHK-22, drilled to the south-southwest at -60 degrees from the west end of the Huayra Kasa underground workings to test the eastern side of the SBBP. This intersection included a higher-grade zone that graded 158.64 g Ag eq/t (9.35g Ag/t, 0.016 g Au/t, 3.43% Zn, 0.71% Pb and 0.03% Sn) over 29.84m from 135.20m to 165.04m. 49% of this 600m long hole contained reportable intersections.

Mineral Resource Definition Drilling at Santa Barbara Breccia Pipe

As reported in the September 6, 2021 press release, Eloro is focusing on defining a maiden NI 43-101 compliant mineral resource in a target area encompassing approximately 1,200m along strike, 500m in width and extending to a depth of 600m in the SBBP and surrounding mineralized envelope. Step-out holes DSB-12 and DSB-13 intersected significant mineralization in altered dacite visually similar to the style of mineralization in the mineralized envelope east of SBBP. A further set of step-out holes (DSB-15 and DSB-16) are being drilled 200m NW of the first step-out to test across the widest part of the magnetic anomaly. Fill-in sectional drilling at 100m intervals, starting with hole DSB-14 which will test across the centre of the SBBP, is in progress.

Three underground drill holes have been completed from the drill bay at the west end of the Santa Barbara adit. This drill can complete holes up to 600m long. DSBU-01 was drilled due east at -20 degrees to test the mineralized envelope of the SBBP. Holes DSBU-02 and DSBU-03 (in progress) are drilled due west at -20 degrees and -50 degrees, respectively, to test the southern margin of the SBBP. Assays on these holes are pending.

Structural work by Dr. Osvaldo Arce, P.Geo., General Manager of Eloro’s Bolivian subsidiary, Minera Tupiza S.R.L. (“Minera Tupiza”), and his geological team indicate that higher grade mineralization appears to follow a north-westerly trend hence the drill holes with a southwest orientation should test this trend quite effectively.

Tom Larsen, CEO of Eloro commented: “Once again Dr Bill Pearson, Dr Osvaldo Arce and the technical team at Iska Iska are delivering with drill hole DHK-21 demonstrating a major intersection over 190 metres long with an average grade of 160.22 g Ag eq/t including up to 350.91 g Ag eq/t over 30.06 metres with significant silver of 112.57g Ag/t. This hole is the highest-grade hole yet within the prolific Santa Barbara Breccia Pipe and surrounding mineralized envelope. In addition, the latest step out holes to the northwest are demonstrating added mineralization, extending the strike length beyond the 1200 m that was initially reported.”

Mr. Larsen continued: “Due to the positive results to date from our drill campaign, initial engineering studies to establish potential economic parameters for mineral resource definition will commence shortly, with a site visit having already been completed by a top Peruvian Engineering firm. More detailed metallurgical studies are also planned.”

Dr. Bill Pearson, P.Geo., Eloro’s Executive Vice President Exploration, commented: “While we are focusing on drilling in the SBBP area, it is important to emphasize that this target is only part of an enormous, mineralized area in the Iska Iska Caldera Complex. We continue to obtain multiple reportable intersections in all holes that we have released. Other major targets, including the Central and Porco Breccia Pipes, require much further drilling in order to fully evaluate them. Our downhole Induced Polarization survey is advancing well, and we hope that this survey will help better define the geometry of the mineralization, especially the higher grade zones with greater sulphide content.”

Dr. Osvaldo Arce, P.Geo., General Manager of Minera Tupiza, said: “While radial drilling at Santa Barbara was very useful for defining the general extent of the breccia pipe and mineralized envelope, more focused directed drilling is now being carried out to confirm the orientation of the mineralized zones. A preliminary structural analysis of the deposit shows a clear NW-SE trend of mineralization, which has been confirmed by the drilling of the step-out holes. Hole DSB-09 which intersected a series of relatively short, mineralized intervals from 1.5m to 15m long (see press release July 6, 2021, and Figure 1) appears to have been drilled parallel to this structural trend hence is not likely representative of the grade and extent of the mineralization in the western part of SBBP. Surface drill holes in progress with azimuths to the southwest across these structures will provide more representative sampling of this mineralization. It is also clear that the deposit displays both lateral and vertical zonation of metals both within the breccia pipe and in the surrounding envelope. Work is in progress to more accurately model this zonation which will be important for mineral resource estimation.”

Note: True width of the mineralization is not known at the present time, but based on the current understanding of the relationship between drill orientation/inclination and the mineralization within the breccia pipes and the host rocks such as sandstones and dacites. It is estimated that true width ranges between 70% and 90% of the down hole interval length but this will be confirmed by further drilling. Percentage metal contents are shown for each element.

Chemical symbols: Ag= silver, Au = gold, Zn = zinc, Pb = lead, Cu = copper, Sn = tin, Bi = bismuth, Cd = cadmium and g Ag eq/t = grams silver equivalent per tonne. Quantities are given in percent (%) for Zn, Pb Cu, Sn, Bi and Cd and in grams per tonne (g/t) for Ag, Au and Ag eq.

Metal prices and conversion factors used for calculation of g Ag eq/t (grams Ag per grams x metal ratio) are as follows:

ElementPrice (per kg)Ratio to Ag

In calculating the intersections reported in this press release a sample cutoff of 30 g Ag eq/t was used with generally a maximum dilution of 3 continuous samples below cutoff included within a mineralized section unless more dilution is justified geologically.

The equivalent grade calculations are based on the stated metal prices and are provided for comparative purposes only, due to the polymetallic nature of the deposit. Preliminary metallurgical tests are in progress to establish levels of recovery for each element reported but currently the potential recovery for each element has not yet been established. While there is no assurance that all or any of the reported concentrations of metals will be recoverable, Bolivia has a long history of successfully mining and processing similar polymetallic deposits which is well documented in the landmark volume “Yacimientos Metaliferos de Bolivia” by Dr. Osvaldo R. Arce Burgoa, P.Geo.

Qualified Person

Dr. Osvaldo Arce, P. Geo., General Manager of Minera Tupiza S.R.L., and a Qualified Person in the context of National Instrument 43-101 (“NI 43-101”), has reviewed and approved the technical content of this news release. Dr. Bill Pearson, P.Geo., Executive Vice President Exploration Eloro, and who has more than 45 years of worldwide mining exploration experience including extensive work in South America, manages the overall technical program working closely with Dr. Arce. Dr. Quinton Hennigh, P.Geo., Senior Technical Advisor to Eloro and Independent Technical Advisor, Mr. Charley Murahwi P. Geo., FAusIMM of Micon International Limited are regularly consulted on technical aspects of the project.

Drill samples are prepared in ALS Bolivia Ltda’s preparation facility in Oruro, Bolivia with pulps sent to the main ALS Global laboratory in Lima for analysis. As announced in the February 26, 2021 press release, Eloro has changed the assay protocol to utilize X-ray fluorescence (XRF) to more accurately analyze higher tin. Tin in the CBP is suspected to occur as cassiterite which is insoluble in acid digestion, and therefore not suited for wet chemical techniques. In addition, other assay protocols have been changed to provide for a more accurate measurement of the wide-ranging suite of polymetallic metals at Iska Iska. Eloro employs an industry standard QA/QC program with standards, blanks and duplicates inserted into each batch of samples analyzed with selected check samples sent to a separate accredited laboratory.

Unfortunately, the ALS Global laboratory in Lima where the Iska Iska samples are being analyzed has had major delays in turnaround time due to the impact of the COVID-19 lockdown of Lima by the Peruvian government. This has restricted availability of critical supplies necessary to carry out analytical work. As a result, there will be delays in reporting of assay results.

Recently, AHK Laboratories, who manage a global network of laboratories have setup operations in Bolivia with the establishment of a preparation laboratory in Oruro. AHK has a strong base of accredited laboratories in South America including Peru, Chile, Brazil and Argentina. Eloro has contracted AHK to provide additional analytical services in order to help reduce the sample backlog. A series of check samples are currently being analyzed by AHK as a QA/QC check.

About Iska Iska

Iska Iska silver-tin polymetallic project is a road accessible, royalty-free property, wholly-controlled by the Title Holder, Empresa Minera Villegas S.R.L. and is located 48 km north of Tupiza city, in the Sud Chichas Province of the Department of Potosi in southern Bolivia. Eloro has an option to earn a 99% interest in Iska Iska.

Iska Iska is a major silver-tin polymetallic porphyry-epithermal complex associated with a Miocene possibly collapsed/resurgent caldera, emplaced on Ordovician age rocks with major breccia pipes, dacitic domes and hydrothermal breccias. The caldera is 1.6km by 1.8km in dimension with a vertical extent of at least 1km. Mineralization age is similar to Cerro Rico de Potosí and other major deposits such as San Vicente, Chorolque, Tasna and Tatasi located in the same geological trend.

Eloro began underground diamond drilling from the Huayra Kasa underground workings at Iska Iska on September 13, 2020. On November 18, 2020 Eloro announced the discovery of a significant breccia pipe with extensive silver polymetallic mineralization just east of the Huayra Kasa underground workings and a high-grade gold-bismuth zone in the underground workings. On November 24, 2020, Eloro announced the discovery of the SBBP approximately 150m southwest of the Huayra Kasa underground workings.

Subsequently, on January 26, 2021, Eloro announced significant results from the first drilling at the SBBP including the discovery hole DHK-15 which returned 129.60 g Ag eq/t over 257.5m (29.53g Ag/t, 0.078g Au/t, 1.45% Zn, 0.59% Pb, 0.080% Cu, 0.056% Sn, 0.0022% In and 0.0064% Bi from 0.0m to 257.5m. Subsequent drilling has confirmed significant values of Ag-Sn polymetallic mineralization in the SBBP and the adjacent CBP. The SBBP thus far extends 800m along strike by 400+m wide and extends to at least 700m depth. CBP extends for 700m along strike by 400+m wide and extends to at least 900m deep.

A substantive mineralized envelope which is open along strike and down-dip extends around the breccia pipes. Continuous channel sampling of the Santa Barbara Adit located to the east of SBBP returned 442 g Ag eq/t (164.96 g Ag/t, 0.46%Sn, 3.46% Pb and 0.14% Cu) over 166m including 1,092 g Ag eq/t (446 g Ag/t, 9.03% Pb and 1.16% Sn) over 56.19m. The west end of the adit intersects the end of the SBBP.

On May 4, 2021, Eloro released results from the first drill hole on the CBP. Hole DCN-01 intersected multiple mineralized intercepts including 196.09 g Ag eq/t (150.25 g Ag/t, 0.10% Sn and 0.05 g Au/t) over 56.2m and containing 342.98 g Ag eq/t (274.0 g Ag/t, 0.16% Sn and 0.16 g Au/t) over 27.53m.

On May 26, 2021 Eloro released results from Hole DSB-07 drilled at -60 degrees to a depth of 683.4m to the southeast from the radial drill platform on SBBP which intersected multiple mineralized intercepts including:

  • 122.66 grams silver equivalent/tonne (“g Ag eq/t”) (35.05 g Ag/t, 0.72% Zn, 0.61% Pb, 0.11% Sn and 0.06 g Au/t) over 123.61m from 236.60m to 360.21m including 205.74 g Ag eq/t (92.30 g Ag/t, 0.57% Zn, 0.85% Pb, 0.18% Sn and 0.07 g Au/t) over 32.32m, from 317.21m to 349.53m.
  • 105.41 g Ag eq/t (8.55 g Ag/t, 1.01% Zn, 0.48% Pb, 0.06% Sn and 0.38 g Au/t) over 173.58m from 449.87m to 623.45m including 199.77 g Ag eq/t (21.90 g Ag/t, 1.18% Zn, 0.93% Pb 0.12% Sn and 0.94 g Au/t) over 39.08m, from 551.19m to 590.27m.
  • 146.19 g Ag eq/t (1.70 g Ag/t, 0.00% Zn, 0.01% Pb, 0.42% Sn and 0.02 g Au/t) over 10.20m from 171.60m to 181.80m in the oxide zone indicating potential for significant Sn mineralization in this strongly leached nearer surface zone.
  • In aggregate, 64% of this 683.4m long hole returned reportable mineralized intervals.

Eloro reported additional multiple holes with significant silver-tin polymetallic Intercepts in the SBBP and CBP on July 6, 2021 including:

  • Hole DSB-08, testing the northeast quadrant of the SBBP, encountered eighteen reportable mineralized intercepts beginning near surface to its terminus at 614.4 m. The longest intercept was 69.89 g Ag eq/t over 252.89m from 355.12 to 608.02m including several higher-grade sections of 196.60 g Ag eq/t including 131.13 g Ag/t over 14.52m, 134.62 g Ag eq/t including 93.25 g Ag/t over 21.08m and 145.35 g Ag eq/t including 2.38% Zn over 10.11m.
  • Hole DSB-10, testing the southwest quadrant of the SBBP and northern part of the CBP, encountered twenty-nine reportable mineralized intercepts beginning near surface to its terminus at 1,019.4m. Tin was notably elevated in many intervals suggesting proximity to a mineralizing intrusive source in this area. Notable intercepts include 114.96 Ag eq/t including 0.325% tin (Sn) over 56.2m from 322.18m to 378.30m including a higher-grade section of 187.98 g Ag eq/t including 0.535% Sn over 28.86m80.71 g Ag eq/t including 0.213% Sn over 74.39m from 474.86 to 549.25m and 118.69 g Ag eq/t over 10.77m from 829.97 to 840.74m.

On July 28, 2021, Eloro reported results from hole DHK-18, drilled due south at -10 degrees from the west drill bay in the Huayra Kasa underground workings, to test the mineralized envelope of the SBBP. This hole intersected 129.65 g Ag eq/t (18.38 g Ag/t, 2.14% Zn, 0.67%Pb, and 0.047% Sn) over 300.75m from 65.14m to 365.91m, including higher grade intervals of 215.54 g Ag eq/t over 72.76m, 163.35 g Ag eq/t over 31.83m and 224.48 g Ag eq/t over 19.39m. This hole intersected significant mineralization approximately 230m below the eastern part of the Santa Barbara adit from which previously reported continuous channel sampling returned 442 g Ag eq/t over 166m (see press release April 13, 2021). 82% of this 446.5m long hole contained reportable intervals.

On September 7, 2021 assay results were reported from a further four (4) additional four holes which tested the mineralized envelope of the Santa Barbara Breccia Pipe (“SBBP”) and the central-southern part of the Central Breccia Pipe (“CBP”), including;

  • Hole DHK-20, drilled from the west end of the Huayra Kasa underground workings at -50 degrees on section with hole DHK-18, which intersected 129.65 g Ag eq/t over 300.75m (see press release dated July 28, 2021), returned 234.19 g Ag eq/t (70.58 g Ag/t, 2.31% Zn, 2.74% Pb and 0.042% Sn) over 53.20m from 139.35m to 192.55m including a higher grade portion of 931.73 g Ag eq/t (367.29 g Ag/t, 5.64% Zn, 13.67% Pb and 0.10% Sn) over 9.26m. Multiple additional significant mineralized intervals occur above and below this intercept. Mineralization occurs within the mineralized envelope east of SBBP in all host rock types.
  • Hole DHK-19, drilled to the southeast at -45 degrees from the west end of the Huayra Kasa underground workings, intersected 108.24 g Ag eq/t (3.14g Ag/t, 0.24 g Au/t, 2.03% Zn and 0.58% Pb) over 48.2m from 46.95m to 95.15m in altered dacite in the mineralized envelope of the SBBP. This includes a higher-grade interval grading 180.76 g Ag eq/t (4.46 g Ag/t, 0.35 g Au/t, 3.57% Zn and 1.05% Pb) over 15.02m. Multiple additional significant mineralized intervals occur above and below this intercept.
  • Hole DCN-04 was drilled at -80 degrees to the north from the northern radial platform of the CBP. This hole intersected seventeen (17) mineralized intersections, principally Sn-Ag-bearing, over its 851.4m length. Best results include 71.54 g Ag eq/t (32.58 g Ag/t and 0.10% Sn) over 97.10m from 134.40 to 231.5m; 101.52 g Ag eq/t (28.74 g Ag/t and 0.19% Sn) over 62.01m from 281.40m to 343.41m; 70.42 g Ag eq/t (28.74 g Ag/t and 0.16% Sn) over 22.59m from 417.05m to 439.64m; and 236.96 g Ag eq/t (92.21 g Ag/t and 0.25% Sn) over 17.45m from 659.55m to 677.00m.
  • Hole DCS-02 was drilled southeast at -60 degrees from the south radial platform of the CBP. This hole, which was drilled to 800.5m, intersected nine (9) reportable Ag-Zn-Pb-Sn mineralized intervals. Best results include 79.53 g Ag eq/t (including 0.21% Sn) over 19.42m, 101.01 g Ag eq/t (32.76 g Ag/t, 0.76% Zn, 0.75% Pb) over 10.47 and 130.95g Ag eq/t (34.14 g Ag/t, 0.10 g Au/t, 1.35% Zn and 0.56 % Pb over 7.40m. Mineralization in the southern part of the CBP is notable for containing significant Zn and Pb as well as Ag and Sn, a metal assemblage more comparable to SBBP and Porco. The northern part of the CBP is dominantly Sn-Ag suggesting a deeper origin for this part of the breccia pipe.

A detailed ground magnetic survey of the Iska Iska property, reported on June 6, 2021, confirmed the extent of the Iska Iska Caldera as determined from geological mapping and satellite interpretation, including Aster data. The SBBP and CBP, both of which have been confirmed by drill-testing, are marked by prominent low anomalies reflecting strong alteration. The magnetic data suggests that the Central and Porco Breccia Pipes likely merge at depth. In addition there is a prominent area of low intensity magnetics northwest of the SBBP which was reported on in this press release.

Geological mapping and satellite interpretation identified a third major breccia pipe target, Porco (South), that is approximately 600m in diameter (South) located southeast of the CBP in the southern part of the Iska Iska caldera complex. The Porco (South) Breccia Pipe target has a similar magnetic signature to the Santa Barbara and Central Breccia Pipes, further confirming the likelihood of it being a major breccia pipe. This target is currently being drill tested. Previous channel sampling in the Porco adit located adjacent the target area 200m to the southeast returned 50m grading 519.35 g Ag eq/t including 236.13 g Ag/t, 1.89 g Au/t, 0.87% Cu, 0.22% Bi and >0.05% Sn over an average sample width of 2.49m.

Currently three diamond drill rigs are active at Iska Iska, two surface rigs and one underground drill. Planned drilling for 2021 is 51,000m with the aim of outlining an initial inferred NI 43-101 compliant mineral resource by Q1 2022. A downhole induced polarization/resistivity (IP/Res) survey is in progress to further define drill targets and aid resource definition drilling. Preliminary metallurgical tests are also in progress. An updated NI 43-101 Technical Report is being prepared by independent consultant Micon International Ltd.

  • Step out drilling northwest of Santa Barbara Breccia Pipe demonstrates room for expansion of the mineralized strike length of the breccia pipe and its surrounding mineralized envelope to over 1.2km
  • Definition drilling in progress to define a maiden NI 43-101 compliant mineral resource within a target block measuring 1,200m along strike, 500m wide and extending to a depth of up to 600m in Santa Barbara Breccia Pipe and its surrounding mineralized envelope

TORONTO, Sept. 07, 2021 (GLOBE NEWSWIRE) — Eloro Resources Ltd. (TSX-V: ELO; OTCQX: ELRRF FSE: P2QM) (“Eloro”, or the “Company”) is pleased to provide an update on its Iska Iska silver-tin polymetallic project in the Potosi Department, southern Bolivia. To date, the Company has completed 58 diamond drill holes totalling 26,982 metres (m) to test major target areas at Iska Iska. This press release reports drilling results from four (4) additional holes which tested the mineralized envelope of the Santa Barbara Breccia Pipe (“SBBP”) (Holes DDHK-19 and DHK-20) and the central-southern part of the Central Breccia Pipe (“CBP”) (Holes DCN-04 and DCS-02). To date, every drill hole that has been assayed has returned multiple reportable mineralized intercepts. Currently three drill rigs are in operation at Iska Iska. Two surface drill rigs are completing drilling at SBBP in order to outline an initial National Instrument 43-101 (“NI-43-101”) compliant resource. A third drill, an underground rig, situated in the west end of the Santa Barbara Adit, is testing the eastern part of SBBP and its mineralized envelope. Figure 1 is a geological plan map showing locations of drill holes and an updated geological interpretation. This map depicts a recently identified robust magnetic anomaly to the northwest of the SBBP where drilling is in progress (see press release June 7, 2021, for an overview of the magnetic results). Figure 2 is a north-south section showing the major potential extension of the SBBP mineralized system. Table 1 provides significant drilling results with definitions of chemical symbols and Table 2 lists holes completed with assays pending as well as holes in progress in the three major target areas. Highlights are as follows:

Highlights:

  • Hole DHK-20, drilled from the west end of the Huayra Kasa underground workings at -50 degrees on section with hole DHK-18, which intersected 129.65 g Ag eq/t over 300.75m (see press release dated July 28, 2021), returned 234.19 g Ag eq/t (70.5 g Ag/t, 2.31% Zn, 2.74% Pb and 0.04% Sn) over 53.20m from 139.35m to 192.55m including a higher grade portion of 931.73 g Ag eq/t (367.29 g Ag/t, 5.64% Zn, 13.67% Pb and 0.10% Sn) over 9.26m. Multiple additional significant mineralized intervals occur above and below this intercept. Mineralization occurs within the mineralized envelope east of SBBP in all host rock types.
  • Hole DHK-19, drilled to the southeast at -45 degrees from the west end of the Huayra Kasa underground workings, intersected 108.24 g Ag eq/t (3.14g Ag/t, 0.24 g Au/t, 2.02% Zn and 0.58% Pb) over 48.2m from 46.95m to 95.15m in altered dacite in the mineralized envelope of the SBBP. This includes a higher-grade interval grading 180.76 g Ag eq/t (4.46 g Ag/t, 0.35 g Au/t, 3.58% Zn and 1.04% Pb) over 15.02m. Multiple additional significant mineralized intervals occur above and below this intercept.
  • Hole DCN-04 was drilled at -80 degrees to the north from the northern radial platform of the CBP. This hole intersected seventeen (17) mineralized intersections, principally Sn-Ag-bearing, over its 851.4m length. Best results include 71.54 g Ag eq/t (32.58 g Ag/t and 0.10% Sn) over 97.10m from 134.40 to 231.5m; 101.52 g Ag eq/t (28.74 g Ag/t and .19% Sn) over 62.01m from 281.40m to 343.41m; 134.33 g Ag eq/t (70.42 g Ag/t and 0.16% Sn) over 22.59m from 417.05m to 439.64m; and 236.96 g Ag eq/t (92.21 g Ag/t and 0.25% Sn) over 17.45m from 659.55m to 677.00.m
  • Hole DCS-02 was drilled southeast at -60 degrees from the south radial platform of the CBP. This hole, which was drilled to 800.5m, intersected nine (9) reportable Ag-Zn-Pb-Sn mineralized intervals. Best results include 79.53 g Ag eq/t (including 0.21% Sn) over 19.42m, 101.01 g Ag eq/t (32.75 g Ag/t, 0.76% Zn, 0.75% Pb) over 10.47 and 130.95g Ag eq/t (34.14 g Ag/t, 0.10 g Au/t, 1.35% Zn and 0.56 % Pb over 7.40m. Mineralization in the southern part of the CBP is notable for containing significant Zn and Pb as well as Ag and Sn, a metal assemblage more comparable to SBBP and Porco. The northern part of the CBP is dominantly Sn-Ag suggesting a deeper origin for this part of the breccia pipe.

Major Potential Extension to Santa Barbara Breccia Pipe

Data from a ground magnetics survey conducted by Eloro (see press release of June 7, 2021) outlined a prominent area of anomalously low magnetic variability northwest of the SBBP, as shown in Figure 1, likely reflecting strong hydrothermal alteration. Subsequent 3D inversion modelling confirmed that this area warranted drill testing as this pattern is comparable to the SBBP and CBP, both marked by similar magnetic anomalies. Recently completed holes DSB-12 drilled southeast at -40 degrees and DSB-13 on section at -65 degrees intersected strongly altered dacite and breccia with widespread mineralization. As depicted in Figure 2, a north-south section, these holes substantially increase the potential strike length of the SBBP and surrounding mineralized envelope to more than 1.2km. Figure 3 shows pictures of representative boxes of mineralized drill core. Sulphide minerals identified include pyrite, galena, sphalerite and chalcopyrite accompanied by cassiterite. Assays are pending but visually the style of mineralization is similar to what has been intersected within drill holes in the mineralized envelope of the SBBP.

Tom Larsen, CEO of Eloro commented: “The Company is pleased to report that the Santa Barbara Breccia Pipe and its surrounding mineralized envelope is in fact much larger than initially envisioned. Our drilling campaign is now focused within this extensive area in order to define an inaugural NI 43-101 compliant mineral resource which we expect to have completed in Q1 2022. In addition, I am pleased to announce that, as a result of the continuing sampling backlog delays at the ALS Laboratory in Lima due to Covid-19 induced issues, the Company has recently commissioned Alfred H Knight (“AHK”) Laboratories of Great Britain along with ALS Laboratories to help alleviate this backlog. AHK is highly recognized, having a global network of accredited laboratories with operations in over 35 countries. They have recently opened facilities in Bolivia, due to the high demand taking place from mining companies in the region. This is a significant development which will improve the reporting of drilling results at Iska Iska going forward.”

Dr. Bill Pearson, P.Geo., Eloro’s Executive Vice President Exploration, commented: “The very encouraging mineralized intersections in the drill holes testing the magnetic anomaly northwest of the SBBP has opened up the potential for a major extension to this target resource area. The strike length of SBBP and its envelope which trends approximately north-northwest is now more than 1.2km and remains open in all directions. The present target area for mineral resource definition is approximately 1.2km along strike, 500m wide and extends to a depth of at least 600m. Drill holes in the CBP continue to return encouraging values but further drilling on this and the Porco target will be deferred until after drilling in the SBBP area is completed. The downhole IP/Res survey at the SBBP is moving along well and will provide important information to better confirm continuity of mineralization between drill holes especially higher-grade zones with greater sulphide content.”

Dr. Osvaldo Arce, P.Geo., General Manager of Eloro’s Bolivian subsidiary Minera Tupiza S.R.L., said: “Interpretation of Aster/Landsat satellite imagery and later, the magnetic survey in the northwestern sector of the SBBP, has outlined a substantial anomalous zone that likely reflects widespread hydrothermal alteration. The first diamond drillholes DSB-12 and DSB-13 holes have intercepted a number of well mineralized intervals in which measurement with the XRF gun confirm Ag, Sn, Pb, Zn and tungsten (W). This mineralization is hosted in dacitic volcanic domes which are cut by local sections of well-mineralized breccias with predominantly dacitic clasts surrounded by a tourmaline matrix that is replaced by sulphides and cassiterite. This discovery extends the SBBP and associated mineralized envelope along strike as much as 50% from its original size. The SBBP has characteristics of a large kilometre-scale and continuous near-surface mineralized body of enriched telescoped polymetallic mineralization.”

Dr. Quinton Hennigh, P.Geo., Senior Technical Advisor to Eloro, commented: “Once again, all recently assayed drill holes returned multiple long mineralized intervals at Iska Iska. The limits of the system keep expanding, the magnetic anomaly to the northwest of the SBBP being the most recent addition. Here, recently completed holes DSB-12 and DSB-13 display very promising long intervals of mineralization with an appearance similar to holes drilled closer to the SBBP. While the 1,200 x 500 x 600 m volume currently being targeted for a maiden resource is impressive, it is important to keep in mind that this is still just a subset of the much larger Iska Iska system that extends over a kilometre further south to the Porco breccia pipe along the southern margin of the caldera complex where Eloro recently drilled some visibly mineralized holes. In short, this major discovery is still in its early days.”

Note: True width of the mineralization is not known at the present time, but based on the current understanding of the relationship between drill orientation/inclination and the mineralization within the breccia pipes and the host rocks such as sandstones and dacites. It is estimated that true width ranges between 70% and 90% of the down hole interval length but this will be confirmed by further drilling. Percentage metal contents are shown for each element.

Chemical symbols: Ag= silver, Au = gold, Zn = zinc, Pb = lead, Cu = copper, Sn = tin, Bi = bismuth, Cd = cadmium and g Ag eq/t = grams silver equivalent per tonne. Quantities are given in percent (%) for Zn, Pb Cu, Sn, Bi and Cd and in grams per tonne (g/t) for Ag, Au and Ag eq.

Metal prices and conversion factors used for calculation of g Ag eq/t (grams Ag per grams x metal ratio) are as follows:

ElementPrice (per kg)Ratio to Ag

In calculating the intersections reported in this press release a sample cutoff of 30 g Ag eq/t was used with generally a maximum dilution of 3 continuous samples below cutoff included within a mineralized section unless more dilution is justified geologically.

The equivalent grade calculations are based on the stated metal prices and are provided for comparative purposes only, due to the polymetallic nature of the deposit. Preliminary metallurgical tests are in progress to establish levels of recovery for each element reported but currently the potential recovery for each element has not yet been established. While there is no assurance that all or any of the reported concentrations of metals will be recoverable, Bolivia has a long history of successfully mining and processing similar polymetallic deposits which is well documented in the landmark volume “Yacimientos Metaliferos de Bolivia” by Dr. Osvaldo R. Arce Burgoa, P.Geo.

Qualified Person

Dr. Osvaldo Arce, P. Geo., General Manager of Minera Tupiza S.R.L., and a Qualified Person in the context of National Instrument 43-101 (“NI 43-101”), has reviewed and approved the technical content of this news release. Dr. Bill Pearson, P.Geo., Executive Vice President Exploration Eloro, and who has more than 45 years of worldwide mining exploration experience including extensive work in South America, manages the overall technical program working closely with Dr. Arce. Dr. Quinton Hennigh, P.Geo., Senior Technical Advisor to Eloro and Independent Technical Advisor, Mr. Charley Murahwi P. Geo., FAusIMM of Micon International Limited are regularly consulted on technical aspects of the project.

Drill samples are prepared in ALS Bolivia Ltda’s preparation facility in Oruro, Bolivia with pulps sent to the main ALS Global laboratory in Lima for analysis. As announced in the February 26, 2021 press release, Eloro has changed the assay protocol to utilize X-ray fluorescence (XRF) to more accurately analyze higher tin. Tin in the CBP is suspected to occur as cassiterite which is insoluble in acid digestion, and therefore not suited for wet chemical techniques. In addition, other assay protocols have been changed to provide for a more accurate measurement of the wide-ranging suite of polymetallic metals at Iska Iska. Eloro employs an industry standard QA/QC program with standards, blanks and duplicates inserted into each batch of samples analyzed with selected check samples sent to a separate accredited laboratory.

Unfortunately, the ALS Global laboratory in Lima where the Iska Iska samples are being analyzed has had major delays in turnaround time due to the impact of the COVID-19 lockdown of Lima by the Peruvian government. This has restricted availability of critical supplies necessary to carry out analytical work. As a result, there will be delays in reporting of assay results.

Recently, AHK Laboratories, who manage a global network of laboratories have setup operations in Bolivia with the establishment of a preparation laboratory in Oruro. AHK has a strong base of accredited laboratories in South America including Peru, Chile, Brazil and Argentina. Eloro will be contracting AHK to provide analytical services in order to help reduce the sample backlog. A series of check samples are currently being analyzed by AHK as a QA/QC check.

About Iska Iska

Iska Iska silver-tin polymetallic project is a road accessible, royalty-free property, wholly-controlled by the Title Holder, Empresa Minera Villegas S.R.L. and is located 48 km north of Tupiza city, in the Sud Chichas Province of the Department of Potosi in southern Bolivia. Eloro has an option to earn a 99% interest in Iska Iska.

Iska Iska is a major silver-tin polymetallic porphyry-epithermal complex associated with a Miocene possibly collapsed/resurgent caldera, emplaced on Ordovician age rocks with major breccia pipes, dacitic domes and hydrothermal breccias. The caldera is 1.6km by 1.8km in dimension with a vertical extent of at least 1km. Mineralization age is similar to Cerro Rico de Potosí and other major deposits such as San Vicente, Chorolque, Tasna and Tatasi located in the same geological trend.

Eloro began underground diamond drilling from the Huayra Kasa underground workings at Iska Iska on September 13, 2020. On November 18, 2020 Eloro announced the discovery of a significant breccia pipe with extensive silver polymetallic mineralization just east of the Huayra Kasa underground workings and a high-grade gold-bismuth zone in the underground workings. On November 24, 2020, Eloro announced the discovery of the SBBP approximately 150m southwest of the Huayra Kasa underground workings.

Subsequently, on January 26, 2021, Eloro announced significant results from the first drilling at the SBBP including the discovery hole DHK-15 which returned 129.60 g Ag eq/t over 257.5m (29.53g Ag/t, 0.078g Au/t, 1.45%Zn, 0.59%Pb, 0.080%Cu, 0.056%Sn, 0.0022%In and 0.0064% Bi from 0.0m to 257.5m. Subsequent drilling has confirmed significant values of Ag-Sn polymetallic mineralization in the SBBP and the adjacent CBP. The SBBP thus far extends 800m along strike by 400+m wide and extends to at least 700m depth. CBP extends for 700m along strike by 400+m wide and extends to at least 900m deep.

A substantive mineralized envelope which is open along strike and down-dip extends around the breccia pipes. Continuous channel sampling of the Santa Barbara Adit located to the east of SBBP returned 442 g Ag eq/t (164.96 g Ag/t, 0.46%Sn, 3.46% Pb and 0.14% Cu) over 166m including 1,092 g Ag eq/t (446 g Ag/t, 9.03% Pb and 1.16% Sn) over 56.19m. The west end of the adit intersects the end of the SBBP.

On May 4, 2021, Eloro released results from the first drill hole on the CBP. Hole DCN-01 intersected multiple mineralized intercepts including 196.09 g Ag eq/t (150.25 g Ag/t, 0.10% Sn and 0.05 g Au/t) over 56.2m and containing 342.98 g Ag eq/t (274.0 g Ag/t, 0.16% Sn and 0.16 g Au/t) over 27.53m.

On May 26, 2021 Eloro released results from Hole DSB-07 drilled at -60 degrees to a depth of 683.4m to the southeast from the radial drill platform on SBBP which intersected multiple mineralized intercepts including:

  • 122.66 grams silver equivalent/tonne (“g Ag eq/t”) (35.05 g Ag/t, 0.72% Zn, 0.61% Pb, 0.11% Sn and 0.06 g Au/t) over 123.61m from 236.60m to 360.21m including 205.74 g Ag eq/t (92.30 g Ag/t, 0.57% Zn, 0.85% Pb, 0.18% Sn and 0.07 g Au/t) over 32.32m, from 317.21m to 349.53m.
  • 105.41 g Ag eq/t (8.55 g Ag/t, 1.01% Zn, 0.48% Pb, 0.06% Sn and 0.38 g Au/t) over 173.58m from 449.87m to 623.45m including 199.77 g Ag eq/t (21.90 g Ag/t, 1.18% Zn, 0.93% Pb 0.12% Sn and 0.94 g Au/t) over 39.08m, from 551.19m to 590.27m.
  • 146.19 g Ag eq/t (1.70 g Ag/t, 0.00% Zn, 0.01% Pb, 0.42% Sn and 0.02 g Au/t) over 10.20m from 171.60m to 181.80m in the oxide zone indicating potential for significant Sn mineralization in this strongly leached nearer surface zone.
  • In aggregate, 64% of this 683.4m long hole returned reportable mineralized intervals.

Eloro reported additional multiple holes with significant silver-tin polymetallic Intercepts in the SBBP and CBP on July 6, 2021 including:

  • Hole DSB-08, testing the northeast quadrant of the SBBP, encountered eighteen reportable mineralized intercepts beginning near surface to its terminus at 614.4 m. The longest intercept was 69.89 g Ag eq/t over 252.89m from 355.12 to 608.02m including several higher-grade sections of 196.60 g Ag eq/t including 131.13 g Ag/t over 14.52m, 134.62 g Ag eq/t including 93.25 g Ag/t over 21.08m and 145.35 g Ag eq/t including 2.38% Zn over 10.11m.
  • Hole DSB-10, testing the southwest quadrant of the SBBP and northern part of the CBP, encountered twenty-nine reportable mineralized intercepts beginning near surface to its terminus at 1,019.4m. Tin was notably elevated in many intervals suggesting proximity to a mineralizing intrusive source in this area. Notable intercepts include 114.96 Ag eq/t including 0.325% tin (Sn) over 56.2m from 322.18m to 378.30m including a higher-grade section of 187.98 g Ag eq/t including 0.535% Sn over 28.86m80.71 g Ag eq/t including 0.213% Sn over 74.39m from 474.86 to 549.25m and 118.69 g Ag eq/t over 10.77m from 829.97 to 840.74m.

On July 28, 2021 Eloro reported results from hole DHK-18, drilled due south at -10 degrees from the west drill bay in the Huayra Kasa underground workings to test the mineralized envelope of the SBBP. This hole intersected 129.65 g Ag eq/t (18.38 g Ag/t, 2.14% Zn, 0.67%Pb, and 0.047% Sn) over 300.75m from 65.14m to 365.91m including higher grade intervals of 215.54 g Ag eq/t over 72.76m, 163.35 g Ag eq/t over 31.83m and 224.48 g Ag eq/t over 19.39m. This hole intersected significant mineralization approximately 230m below the eastern part of the Santa Barbara adit from which continuous channel sampling previously reported returned 442 g Ag eq/t over 166m (see press release April 13, 2021). 82% of this 446.5m long hole contained reportable intervals.

A detailed ground magnetic survey of the Iska Iska property reported on June 6, 2021 confirmed the extent of the Iska Iska Caldera as determined from geological mapping and satellite interpretation including Aster data. The SBBP and CBP, both of which have been confirmed by drill-testing, are marked by prominent low anomalies reflecting strong alteration. The magnetic data suggests that the Central and Porco Breccia Pipes likely merge at depth. In addition there is a prominent area of low intensity magnetics northwest of the SBBP which is reported on in this press release.

Geological mapping and satellite interpretation identified a third major breccia pipe target Porco (South) that is approximately 600m in diameter (South) located southeast of CBP in the southern part of the Iska Iska caldera complex. The Porco (South) Breccia Pipe target has a similar magnetic signature to the Santa Barbara and Central Breccia Pipes, further confirming the likelihood of it being a major breccia pipe. This target is currently being drill tested. Previous channel sampling in the Porco adit located adjacent the target area 200m to the southeast returned 50m grading 519.35 g Ag eq/t including 236.13 g Ag/t, 1.89 g Au/t, 0.87% Cu, 0.22% Bi and >0.05% Sn over an average sample width of 2.49m.

Currently three diamond drill rigs are active at Iska Iska, two surface rigs and one underground drill. Planned drilling for 2021 is 51,000m with the aim of outlining an initial inferred NI 43-101 compliant mineral resource by Q1 2022. A downhole induced polarization/resistivity (IP/Res) survey is in progress to further define drill targets and aid resource definition drilling. Preliminary metallurgical tests are also in progress. An updated NI 43-101 Technical Report is being prepared by independent consultant Micon International Ltd.

Eloro Resources Provides Update on its La Victoria Silver, Gold Project, Peru

TORONTO, Aug. 26, 2021 (GLOBE NEWSWIRE) — Eloro Resources Ltd. (TSX-V: ELO; OTCQX: ELRRF FSE: P2QM) (“Eloro”, or the “Company”) is pleased to announce that in connection with required permitting for continued exploration at La Victoria, it’s 82%-owned Peruvian subsidiary, Compañia Minera Eloro Peru S.A.C. (“Eloro Peru”), entered into a surface rights agreement (the “Agreement”) with the Pallasca Community in the Pallasca Province, Ancash Department, Peru. The Agreement allows exploration activities, including drilling, to proceed at the San Markito epithermal silver drill target.

The San Markito target is located within the Victoria-APB Concession in the Pallasca District and Province, 430 km NNE of Lima, Peru. Surface mapping and sampling to date has confirmed high silver grades within a silicified breccia structure located at an altitude of 4050m above sea level. Significant silver values from San Markito include 994 g/t Ag with 0.35 g/t Au in a continuous diamond saw channel sample over 4.00m and 390 g/t Ag with 0.53 g/t Au over 1.53m (see December 14, 2016 Eloro Press Release). Induced polarization survey results indicate a steeply dipping low resistivity and higher chargeability anomaly at depth, spatially correlated with the surface mineralization. A 3000m drill program to test the continuity of the breccia mineralization along strike and down-dip is planned.

Since 2016, Eloro Peru has been actively engaged with local stakeholders from the Pallasca community and nearby hamlets in order to provide the necessary information to all concerned members. On July 24 2021, an extraordinary community assembly took place, where a majority of community members voted in favour of Eloro Peru’s land use proposal. Apart from the land rental payment, Eloro has also agreed to help the community avail itself to government infrastructure funds to enhance the community’s agricultural practices and access to water.

With the Agreement in place, Eloro Peru can now proceed with the drill permitting process with the Peruvian Ministry of Energy and Mines and the Water Authority. Geades Consulting S.A.C has been retained for this purpose.

Geological operations will recommence in September, 2021, under the supervision of Chief Geologist (Peru), Marcelo Alvarez, who led Eloro Peru’s 2017-2018 exploration activities. Mr. Alvarez brings 30 years of exploration experience in South American epithermal, mesothermal and porphyry deposit types. He also has extensive knowledge in the modeling and evaluation of mineral resources.

Eloro’s La Victoria joint venture partner, Burgundy Diamond Mines Limited, holds an 18% interest in Eloro Peru and pursuant to an option agreement, can increase their interest from 18% to 25% by expending a further $1,400,000, subject to the receipt of all required permitting.

Qualified Person

Luc Pigeon, B.Sc., M.Sc., P. Geo., General Manager of Compañia Minera Eloro Peru S.A.C. and a Qualified Person in the context of National Instrument 43-101 (“NI 43-101”), has reviewed and approved the technical content of this news release.

Eloro Delivers Universe Class Results

Bob Moriarty
Archives
Jul 30, 2021

I wrote about Eloro about three weeks ago and pretty much covered the story. The Iska Iska project in Southern Bolivia will be a mine. It is far too big and far too rich not to be a mine under any commodity prices.

The company released drill results on July 28th that probably would not qualify as just world class but it would be more accurate to call it universe class results with 300.75 meters of 129.65 g/t Ag eq.

(Click on images to enlarge)

As I did in my last piece a few weeks ago on Eloro I’m going to cheat a little bit and convert the silver eq into grams of gold. The intercept had a value of about $106 USD per tonne and while 2 grams per tonne gold eq would be about $117, it’s close enough for government work to use 2 grams for ease of understanding.

If you cube the 300.75 meters and use a s/g of 2.7 you get just over 54 million tonnes. Factor in the 2.0 grams and the POG right now of $1831 you have a hole showing about 3.5 million ounces of gold and a total value of $6.4 billion. Since 2 grams of gold is worth about 10% more than the 129.65 grams of silver, reduce that to about $5.8 billion for one hole. In every other case I have used this technique of cubing a hole I say that of course that is the very maximum value you could get out of one cube of that grade. In the case of Iska Iska, it’s entirely possible, indeed probable that they will have cubes of that size and that grade.

Sorry folks but the market just doesn’t get it.

I took the highest gram meter intercept from New Found Gold, which is also a mine in the making, and did the same cube trick because I want potential investors to understand how important long intercepts are. New Found Gold had a world class intercept of 146.2 grams of gold over 25.6 meters for an incredible 3,742 gram meter. That is $8,600 rock. A cubic meter would be worth $23,220.

When you cube it and compare it to Eloro’s hole you get an amazing difference due to the giant length of the 300-meter Iska Iska hole. Eloro had a 54 million tonne hole, NFG had a 45,298 tonne hole. Iska Iska had about 3.15 million ounces compared to 213,000 ounces for NFG. Now I do not want to take anything away from New Found Gold. The company has put in an incredible discovery program and is one of the greatest gold discoveries in the last five years but Iska Iska has a $6 billion hole compared to a respectable $389 million hole for NFG.

As of the close on July 29th, ELO had a market cap of $257 million and they are holding $23 million in cash. The only thing holding them back from bringing in more drills and increasing the speed of exploration is the backlog of 26,000 samples due to Covid.

As an aside, Cartier Iron holds about 2.4 million shares of ELO worth right at $10 million. At a close of $.13 on July 29th, CFE has a market cap of only $11.7 million.

Eloro is an advertiser. I have participated in several private placements in the past and bought shares in the open market. I am naturally biased so do your own due diligence.
