TORONTO, April 27, 2022 (GLOBE NEWSWIRE) — Eloro Resources Ltd. (TSX-V: ELO; OTCQX: ELRRF; FSE: P2QM) (“Eloro”, or the “Company”) is pleased to announce assay results from an additional six (6) diamond drill holes from its on-going drilling program at the Iska Iska silver-tin polymetallic project in the Potosi Department, southern Bolivia. Holes DSBU-05 and DSBU-06 are underground holes drilled from the Santa Barbara adit to test the northern extension of the higher-grade mineralized zone. Hole DSBS-01 was collared in the southern part of the Santa Barbara target zone and drilled at an azimuth of 30⁰ and dip of -30⁰ to test the same target^. Holes DSB-24, DSB-14 and DSB-22 were drilled at azimuths of 225⁰ to test the northwest extension of the Santa Barbara mineralized zone approximately 100m, 200m, and 1,000m, respectively, northwest of the Santa Barbara adit underground drill bay. Drilling is continuing in the Porco area to test for a potential Sn porphyry as suggested by the 3D inverse magnetic model (see Eloro press release March 1, 2022). Thus far, 4,870 m in five (5) holes have been completed in the Porco target area with assays pending.

Overall, the Company has completed 52,384m in 89 drill holes to-date, including four holes in progress, as shown in Figures 1 and 2. Currently there are three (3) surface drills and one (1) underground drill operating at Iska Iska. Tables 1, 2 and 3 list significant assay results for the drill holes in the major target areas. Prices used for calculating Ag equivalent grades are as outlined in Eloro’s February 1, 2022, press release. Table 4 summarizes drill holes with assays pending. Highlights are as follows:

Santa Barbara Mineral Resource Definition Target Area – Underground Drilling

Underground holes DSBU-06 and DSBU-05 were both drilled on azimuth 0⁰ and dips of -65⁰ and -40⁰, respectively, from the Santa Barbara adit to test the northern extent of higher-grade mineralization in the eastern part of the Santa Barbara target area.

• Hole DSBU-06 intersected 169.11 g Ag eq/t (64.30 g Ag/t, 0.96% Zn, 0.37% Pb and 0.07% Sn) over 235.55m from 0.00m to 235.55m, including a higher-grade section of 314.52 g Ag eq/t (192.18 g Ag/t, 0.22 g Au/t, 0.07% Zn, 0.41% Pb, and 0.11% Sn) over 50.68m from 24.40m to 75.08m.
  • This hole had a second major intersection of 110.57 g Ag eq/t (17.38 g Ag/t, 0.09 g Au/t, 0.30% Zn, 0.21% Pb and 0.11%Sn) over 128.44m from 264.14m to 392.58m.
  • Overall, 86% of this 599.8m long hole had reportable intersections which collectively average 129.70 g Ag eq/t.
• Hole DSBU-05 intersected 141.05 g Ag eq/t (22.99 g Ag/t, 0.07 g Au/t, 0.18% Zn, 0.16% Pb, 0.21% Cu and 0.12% Sn) over 153.25m from 0.00m to 153.25m which included high grade sections of:
  • 201.23 g Ag eq/t (21.77 g Ag/t, 0.06 g Au/t, 0.36% Zn, 0.30 %Pb, 0.63 %Cu and 0.12% Sn) over 34.97m from 0.00m to 34.97m,
  • 206.03 g Ag eq/t (24.52 g Ag/t, 0.18 g Au/t, 0.14% Zn, 0.16 %Pb, 0.11% Cu and 0.23% Sn) over 9.05m from 76.94m to 85.99m, and
  • 242.83 g Ag eq/t (31.67 g Ag/t, 0.04 g Au/t, 0.23% Zn, 0.19% Pb, 0.17% Cu and 0.28% Sn) over 25.60m from 109.93m to 135.53m.
  • Hole DSBU-05 has a second major intersection lower in the hole from 348.08m to 526.17m of 92.47 g Ag eq/t (23.86 g Ag/t, 0.96% Zn, 0.21% Pb) over 178.09m.
  • Overall, 65% of this 641.9m long hole had reportable intersections which collectively average 107.73 g Ag eq/t.
    

Dr. Bill Pearson, P.Geo. Executive Vice President, Exploration commented: “As shown in Figure 3, a N-S cross section looking east, holes DSBU-06 and DSBU-05 define a significant extension to the north of the major high grade mineralized area in the southern part of Santa Barbara. Further drilling, especially deeper, is in progress to define the full extent of this important high-grade zone. Analysis of borehole IP data and the 3D inverse magnetic model by Eloro’s geophysicists Dr. Chris Hale, P.Geo. and John Gilliatt, P.Geo. shows that the Mx Chargeability indicates stronger mineralization at greater depth as shown in Figure 4. The spatial agreement between the interpolated chargeability and the mineralization intersected in these holes also suggests that the mineralized zone may dip steeply to the south. Further deeper drilling will be carried out to test this highly prospective target. Drilling will also be carried out from the southwest to test the Northwest Extension target as the best mineralization intersected thus far is in the southern part of this target zone.”

Dr. Pearson continued, “The addition of a fourth drill and the more rapid turnaround from both our assay laboratories at ALS and AHK has allowed us to increase the pace of the exploration drill program considerably. In the next 2-3 weeks we expect to have the GeologicAI core scanner on site. We have worked closely with GeologicAI to build the database for the scanner from all our available geological and geochemical information. The scanner will allow us to better outline and track the mineral and metal zonation at Iska Iska, which is critical to efficiently explore this remarkable mineralizing system which remains open in all directions.”

Dr. Osvaldo Arce, P.Geo., General Manager of Eloro’s Bolivian subsidiary Minera Tupiza S.R.L. (“Minera Tupiza”), further commented: “The dacitic volcanic domes and breccia pipes at Iska Iska, which are the primary hosts of the epithermal polymetallic Ag-Zn-Pb-Sn mineralization, appear to extend to a depth of at least 1km. These intrude altered granodiorite and intrusion breccias that are the primary hosts of xenothermal tin and other higher temperature metals such as bismuth and tungsten. The mineralization is quite complex in detail with extensive breccias, veins, veinlets, stockworks and disseminations. The likely primary distribution of both epithermal and xenothermal mineralization is indicated by the metal zonation, alteration zonation and geophysical responses. This data indicates that the mineralized system strengthens with depth and may be much more extensive than indicated in shallower drill holes.”

Table 1: Significant Results, Underground Diamond Drilling, Santa Barbara Resource Definition Target Area as at April 27, 2022.

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 and geological modelling.

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 (Prices updated as of February 1, 2022, to more accurately reflect current metal prices):

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. Metallurgical tests are in progress by Blue Coast Ltd. 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.

Eloro is utilizing both ALS and AHK for drill core analysis, both of whom are major international accredited laboratories. Drill samples sent to ALS are prepared in both ALS Bolivia Ltda’s preparation facility in Oruro, Bolivia and the preparation facility operated by AHK in Tupiza with pulps sent to the main ALS Global laboratory in Lima for analysis. More recently Eloro has had ALS send pulps to their laboratory at Galway in Ireland. 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.

Drill core samples sent to AHK Laboratories are prepared in a preparation facility installed and managed by AHK in Tupiza with pulps sent to the AHK laboratory in Lima, Peru. Au and Sn analysis on these samples is done by ALS Bolivia Ltda in Lima. Check samples between ALS and AHK are regularly done as a QA/QC check. AHK is following the same analytical protocols used as with ALS and with the same QA/QC protocols. Turnaround time continues to improve, as laboratories return to more normal staffing levels.

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 initial discovery hole, Eloro has released a number of significant drill results in the SBBP and the surrounding mineralized envelope which along with geophysical data has defined a target zone 1400m along strike, 500m wide and that extends to a depth of 600m. This zone is open along strike to the northwest and southeast as well as to the southwest. The Company’s nearer term objective is to outline a maiden NI 43-101 compliant mineral resource within this large target area. This work is advancing well with the mineral resource targeted to be completed in Q3 2022. Exploration drilling is also planned on other major targets in the Iska Iska Caldera Complex, including the Porco and Mina 2 areas.
