Granite Creek Copper Announces Updated NI 43-101 Mineral Resource Estimate for High Grade Carmacks Copper-Gold-Silver Project in Yukon Canada Highlighted by 43% Increase in Measured and Indicated Contained Copper

VANCOUVER, BC / ACCESSWIRE / March 15, 2022 / Granite Creek Copper Ltd. (TSXV:GCX)(OTCQB:GCXXF) (“Granite Creek” or the “Company“) is pleased to announce an updated mineral resource estimate (the “2022 Resource Estimate”) for the Company’s 100%-owned Carmacks copper-gold-silver deposit (“Carmacks” or the “Deposit”) located in the Minto Copper District of central Yukon, Canada. The 2022 Resource Estimate represents a major increase in tonnage and contained metal at Carmacks compared to the previous resource estimate1,2, with over 8,200 m of infill and expansion drilling in 25 holes completed by Granite Creek since its acquisition in 2020. The project remains open to significant expansion within the resource area and to new discovery at the underexplored, yet highly prospective, Carmacks North target area.

Highlights

  • 43% Increase in Contained Copper – The high grade Carmacks deposit now hosts 36.2 million tonnes (Mt) in Measured and Indicated categories (M&I), grading 1.07% CuEq (0.81% Cu, 0.26g/t Au, 3.23g/t Ag and 0.011% Mo) for a total of 651 million pounds (Mlbs) of contained M&I copper and an additional 38 Mlbs Cu Inferred (see table 1). The previous resource estimate published in 2018 defined 25.0 Mt M&I, grading 0.83% Cu, equating to 457 Mlbs of contained copper. (Figure1)
  • Expansion of Gold and Silver Resources – Contained gold (M&I) increased 24% from 243,000 ounces to 302,000 ounces and contained silver (M&I) increased 41% from 2,684,000 ounces to 3,790,000 ounces.
  • Addition of Molybdenum Resources – For the first time, molybdenum has been included in the resource estimate, with 8.5 Mlbs lbs in M&I.
  • 93% of Resources in the M&I Categories – Only 7% of the 2022 resource remains in the Inferred category.
  • High Proportion of Resources Modeled in Three Conceptual Open Pits – 96% of the 2022 resources are contained within the conceptual pits. (Figure 2)
  • High Grade Copper-Gold in a Producing District – The 2022 Resource Estimate continues to advance the Carmacks project as one of the highest-grade resource-stage copper projects in North America.

Timothy Johnson, Granite Creek President & CEO, stated, “Since completing the acquisition the Carmacks deposit in November 2020, the Company has been successful in significantly growing copper, gold and silver resources through highly targeted drilling in 2020 and 2021. Our conceptual deposit model held up extremely well, with significant mineralized intercepts encountered in 22 of the 25 holes we drilled. The mineral resources contained within the conceptual pits will form the basis for an updated Preliminary Economic Assessment (“PEA”) which the Company intends to initiate immediately. This study will assess the economics of processing both oxide and sulphide material as well as by product credits including gold, silver and molybdenum.”

“From an exploration perspective, there remains the opportunity continue increasing copper resources by continued step out drilling on existing zones, adding to this resource. There is also high potential for discovery of new zones by applying the Company’s increased understanding of the geological controls of mineralization and we remain committed to adding to this mineral inventory through continued exploration. “

Live Webinar

Granite Creek Copper will be hosting a live webinar on Thursday, March 17 at 10am PT (1pm ET), during which President & CEO, Timothy Johnson will be joined by Project Geologist, Dr Jacob Longridge, for a comprehensive update on the Company’s Carmacks copper-gold silver project, including Q&A.

Figure 1 – Increase in Contained Copper

Table 1 – 2022 Carmacks Copper Project Mineral Resources

Cu=copper, Au=gold, Mo=molybdenum, Ag=silver, Mt=millions of tonnes, Mlbs=millions of pounds, klbs=thousands of pounds, koz=thousands of ounces. Mineral Resources are reported using the 2014 CIM Definition Standards. Mineral Resources are reported within a conceptual constraining pit shell that includes the following input parameters: Metal prices of $3.60/lb Cu, $1,750/Au, $22/oz Ag, $14/lb Mo and pit slope angles that vary from 35° for overburden to 55°for granodiorite host, metal prices are in US$. Metallurgical recoveries reflective of prior test work that averages: 85% Cu, 85% Au, 65% Ag in the oxide domain and 90% Cu, 76% Au, 65% Ag in the sulphide domain. Mo recovery is assumed to be 70% in both oxide and sulphide domain. Tonnes are metric tonnes, with Cu and Mo grades as percentages and Au and Ag grades as gram per tonne units. Cu and Mo metal content is reported in lb and Au and Ag content is reported in troy oz. Totals and Metal content may not sum due to rounding and significant digits used in calculations. Cu Eq calculation is based on 100% recovery of all metals using the same metal prices used in the resource calculation: $3.60/lb Cu, $1,750/Au, $22/oz Ag, $14/lb Mo.

Grade Sensitivity

A copper and copper equivalent grade sensitivity analysis for both oxide and sulphide resources contained in the proposed pits is provided in Table 2 below, which demonstrates the variation in grade and tonnage in the deposit at these various cut-off grades. This sensitivity analysis is reflective of the discrete nature of the mineralized bodies. Comparing the cut-off grade of 0.30% Cu with a 0.25% Cu and a 0.35% Cu cut-off, show a <3% variation in contained copper and a ~5% variation in the tonnage.

Table 2 – Grade Sensitivity Table

Mineralization

Mineralization is constrained to discrete tabular bodies of schistose to gneissic metamorphic rock. These tabular bodies are enveloped in granodiorite that dominates the majority of the Carmacks project. The contact between these tabular metamorphic bodies and granodiorite is sharp, with little to no gradation between these units. This sharp contact creates a very distinct geochemical and geophysical pattern between the two rock types assisting in exploration vectoring.

Upon acquiring the Carmacks Deposit in 2020, Granite Creek immediately recognized the potential of the relatively untested sulphide portion that may significantly alter the scope and scale of the deposit. This conceptual understanding has been validated with the sulphide resources now roughly equal in size to the oxide resources and provides the case for an updated PEA, which will evaluate the economics of both the oxide and the sulphide portions of the resource.

Copper mineralization in the oxide domain is primarily malachite and azurite with copper sulphides accounting for up to 20% of the copper tenor in the form of chalcopyrite. A surface representing the boundary between the upper oxide and lower sulphide mineralization was interpolated based on drill hole intersections. The depth of transition between oxide to sulphide is variable in each zone. The boundary between the oxide and sulphide is defined by the solubility of copper in sulphuric acid, when >20% of total copper total tenor is soluble in sulphuric acid, the domain is classified as a copper oxide domain. Conversely, the sulphide domain is defined where <20% of the total copper is soluble in sulphuric acid, as per the previous resource. The previously defined ‘transitional zone’ is largely re-classified as part of the sulphide domain. The copper in the upper 200m of zone 1, is oxidized, whereas in zones 13 and 12, the oxidized zone can be as thin as 40m, zones 4 and 7 are primarily oxide (Figure 2). The copper sulphides in the sulphide domain consist primarily of course grained chalcopyrite, bornite and minor chalcocite and covellite.

Previous metallurgical testing has shown that the oxide copper is very amenable to leach extraction with recoveries of greater than 85% New metallurgical results from 2021 test work showed that a ~67% liberation of copper sulphide minerals is possible at 154um P80 primary grind, considering most two-product copper concentrations operate with 50-60% liberation in floatation feed, this is considered excellent and possibly coarser grinds may be sufficient in liberating copper. Flotation testing showed a 25% copper concentrate grade could be produced with recoveries of up to 95% of copper and 85% for gold, with gold reporting closely to the copper. Continuing metallurgical test work will include determining recoveries for silver and molybdenum as well as additional testing to confirm the copper and gold recoveries.

Estimation Methodology and Parameters

The classification of the current Mineral Resource Estimates into Measured, Indicated and Inferred are consistent with current 2014 CIM Definition Standards – For Mineral Resources and Mineral Reserves. All figures are rounded to reflect the relative accuracy of the estimate.

Completion of the 2022 Resource Estimate involved the assessment of a drill hole database, which included all data for surface drilling completed through the fall of 2021, as well as 3D mineral resource models, and available written reports. SGS used 489 surface drillholes and 56,679 meters of drill data from 1970 to 2021 to delineate three deposits (zones 147 combined, zone 2000S and zones 12 and 13 combined) in the 2022 resource estimate. Thirty-six holes (RC and diamond) totalling 9,413m completed by Granite Creek between October 2020 and October 2021 are included.

Composites of 2.0 metre used for the resource estimation procedure have been capped where appropriate. Grades for Cu (oxide, sulphide and total), Ag, Au and Mo for each deposit were interpolated into blocks 5m by 5m by 5m by the Inverse Distance Squared (ID2) calculation method. Appropriate interpolation parameters were generated for each deposit based on drill hole spacing, mineralization style and geometry.

All Resources are presented undiluted and in situ, constrained by continuous 3D wireframe models, and are considered to have reasonable prospects for eventual economic extraction. It is envisioned that parts of the Carmacks Project deposits may be mined using open pit mining methods. In- pit mineral resources are reported at a base-case cut-off grade of 0.30 % total copper(“Cu_T”) within conceptual pit shells. A pit slope of 55 degrees for rock and 35 degrees for overburden are used for the pit optimization. It is envisioned that parts of the Carmacks Project deposits may be mined using lower cost underground bulk mining methods. A selected base-case cut-off grade of 0.6 % Cu_T is used to determine the below pit resources.

Cut-off grades are based on metal prices of $3.60/lb Cu, $22.00/oz Ag, $1,750/oz Au and $14.00/lb for Mo, processing and G&A cost of $US23.00 per tonne milled, and variable mining costs including $US2.10 for open pit and $US25.00 for underground. The cut-off grades should be re-evaluated in light of future prevailing market conditions (metal prices, mining costs, processing costs etc.).

Metal recoveries used for pit optimization and calculation of base-case cut-off grades include: for oxide material 85% for copper, 65% for Ag, 85% for Au and 70% for Mo; for sulphide material, 90% for copper, 65% for Ag, 76% for Au and 70% for Mo. Fixed specific gravity values of 2.64 for oxide material and 2.71 – 2.78 (depending on deposit) were used to estimate the Mineral Resource tonnage from block model volumes. Waste in all areas was given a fixed density of 2.66.

Mineral resources are not mineral reserves and do not have demonstrated economic viability. An Inferred Mineral Resource has a lower level of confidence than that applying to a Measured and Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration. The results from the pit optimization are used solely for the purpose of testing the “reasonable prospects for economic extraction” by an open pit and do not represent an attempt to estimate mineral reserves. There are no mineral reserves on the Carmacks Property. The results are used as a guide to assist in the preparation of a Mineral Resource statement and to select an appropriate resource reporting cut-off grade.

Quality Control and Quality Assurance

Quality assurance and quality control procedures for drilling completed by the Company and consultants to the Company include the systematic insertion of duplicate, blank and standard samples, making up 12% of the sample stream. Drill core samples were sawn in half, labelled, placed in sealed bags and shipped directly to the Bureau Veritas preparation laboratory in Whitehorse. All geochemical analyses were performed by Bureau Veritas in Vancouver. Copper, molybdenum and silver analysis was performed by four-acid digestion with an ICP-ES finish. Non-sulphide copper was determined through a sulphuric acid leach with an AAS finish. Gold was analyzed by igniting a 15 g sample followed by an aqua regia digestion with an ICP-MS finish.

GoldSpot Discoveries Identifies New Targets at Granite Creek’s Carmacks Copper-Gold Project Using Proprietary Artificial Intelligence Technology

Toronto, Ontario–(Newsfile Corp. – February 15, 2022) – GoldSpot Discoveries Corp. (TSXV: SPOT) (OTCQX: SPOFF) (“GoldSpot” or the “Company“), a leading technology services company leveraging machine learning to transform the mineral discovery process, is pleased to announce it has completed work on Granite Creek Copper Ltd.’s (TSXV: GCX) (OTCQB: GCXXF) (“Granite Creek”) Carmacks deposit and Carmacks North target areas, located in the high-grade Carmacks Copper Belt of Canada’s Yukon Territory.

GoldSpot and Granite Creek collaborated to create prioritized exploration and drill targets on the 176 km2 Carmacks copper-gold property. The approaches taken during this collaboration include:

  • Re-interpretation of geophysical data using GoldSpot’s GeoFEZ software;
  • Supervised learning of various combinations of geophysical, topographic and surface geochemical data;
  • Detailed statistical analysis of multi-element geochemical data;
  • Map-based prospectivity analysis and exploration target generation;
  • Generation of a revamped 3D geological model; and
  • Initial test study of company core logging compared with historic imagery, using GoldSpot’s LithoLens.

Proof of concept was achieved when GoldSpot identified several grass-roots target areas previously identified by the Granite Creek team, but not shared with the GoldSpot team. Additional regional targets are new to the Granite Creek team and will be evaluated in the coming field season.

GoldSpot’s collaboration with Granite Creek produced several potential new targets for 2022 exploration and resource expansion, including sub-parallel raft-like domains of possible mineralization adjacent to zones 147, 2000S and 13 at the Carmacks deposit. These were initially hinted at through data mining of the drill hole database. Follow-up geochemical analysis and 3D models suggest a previously unrecognized relationship between geochemistry and mineralized zones, specifically a tell-tale halo around mineralization. These halos indicate several areas for follow-up drill testing. New regional targets have also been produced at Carmacks North using multiple geophysical techniques, including aeromagnetic and induced polarity (IP) surveys.

Vincent Dubé-Bourgeois Chief Executive Officer for GoldSpot commented, “The technologies developed by GoldSpot to provide its innovative technology to partners such as Granite Creek and provided excellent results. The targets generated by GoldSpot AI showed the exploration potential on the Carmacks project.”

Granite Creek President and CEO Tim Johnson stated, “The prospectivity of the Carmacks project has been confirmed and expanded on by the excellent work completed by GoldSpot. The number of new targets combined with the existing targets developed from historical data continues to support our assertion that there is a lot of discovery yet to be made on the property. GoldSpot’s work has advanced our understanding of the property and will become an integral part in our planning for our 2022 exploration program. We look forward to discussing our plans for the upcoming field season and we are on track to deliver a significant update to the existing NI 43-101 mineral resource estimate in Q1, as expected.”

Granite Creek Copper Launches Phase 3 of 2021 Drill Program at Carmacks Copper-Gold Project

VANCOUVER, BC / ACCESSWIRE / September 15, 2021 / Granite Creek Copper Ltd. (TSX.V:GCX)(OTCQB:GCXXF) (“Granite Creek” or the “Company“) is pleased to announce the successful completion of Phase 2 of its 2021 drilling program, consisting of 20 holes of reverse circulation (“RC”) drilling on Zones 2, 5 and 12 at the Carmacks deposit, as well as step-out drilling at Zone A in the Carmacks North target area. The Company has now launched the third and final phase of the 2021 drill campaign, returning to Zone 2000S at the Carmacks deposit to complete offsets of hole CRM21-011 where the Company intercepted a 105.52-meter interval of copper sulphide mineralization grading 1.18% CuEq (0.96% Cu, 0.01% Mo, 0.18 g/t Au, and 4.06 g/t Ag), including a high-grade intercept of 2.55% CuEq (2.17% Cu, 0.01% Mo, 0.36 g/t Au and 9.13 g/t Ag) over 21.22 meters (see news release dated August 24, 2021). The goal of Phase 3 is to continue to expand known resources and confirm the geometry in Zone 2000S to support the development of a mine plan for the sulphide portion of the deposit now underway by Sedgman and Mining Plus.

Granite Creek drilled 19 diamond core holes in the first phase of 2021 drilling, with assays from 9 holes released to date and results from the remaining 10 holes expected in the near term. Samples from the RC program have been sent for assay and will be announced over the next quarter as they become available.

Granite Creek President & CEO, Tim Johnson, commented, “We are very pleased with our 2021 exploration season to date and are excited to enter the final phase of drilling for the year. Given the very strong results we have seen from the first phase of diamond drilling and the positive implications we expect them to have for our resource expansion efforts, the Company adjusted the third phase to return to Zone 2000S where we see substantial opportunity to define additional new areas of mineralization outside the current resource model. Bringing this sulphide material into the model is expected to increase the current NI 43-101 mineral resource estimate in our planned update, with a view to a potentially significant extension of the projected mine life in an updated PEA for Q1 2022. We look forward to continued, substantive news flow throughout the remainder of the year and into 2022.”https://s.yimg.com/rq/darla/4-9-0/html/r-sf-flx.html

VANCOUVER, BC / ACCESSWIRE / July 22, 2021 / Granite Creek Copper Ltd. (TSX.V:GCX)(OTCQB:GCXXF) (“Granite Creek” or the “Company“) is pleased to announce the first tranche of assays from Phase 1 of the Company’s 2021 drilling program on its 100%-owned Carmacks project. This recently completed first phase consisted of nineteen diamond drill holes, totalling 6355 meters, focused on the existing resource area with the goals of strengthening confidence in the resource model, evaluating opportunities for resource expansion and/or upgrading the sulphide portion of Zones 1 and 2000S from an inferred to indicated resource, and evaluating continuity of mineralization in Zone 13 (Figure 1).

Granite Creek President & CEO, Tim Johnson, commented, “The Company is extremely pleased with the progress of 2021 exploration program at Carmacks. A Phase 3 drilling program is under development and projected to commence in mid-August of this year. The addition of this third stage would expand the overall 2021 campaign to include a total of 10,000 meters of diamond drilling as well as 3000m of reverse circulation drilling. We expect this program will significantly expand the total contained metal on the project, resulting in a substantially and form the basis for a new Preliminary Economic Assessment.”

Zone 1

Eight holes were drilled in Zone 1 with the objective of increasing confidence in the inferred portion of the sulfide resource of this zone as well as evaluating the southern down-dip continuation of the inferred resource (Figure 2). The drilling was successful in achieving its objectives of delineating the depth extent of mineralization, expanding the mineralization below the current resource model and confirming the grade and anticipated thickness in the inferred portion of the sulphide resource in this zone.

While the Preliminary Economic Assessment (“PEA”) published in 2017(1,2) only looked at the oxide material in Zones 1,4 & 7, work being conducted by Sedgman and Mining Plus (see news release dated May 18, 2021) is looking at various scenarios to process the sulfide portion of Zone 1 and other sulfide zones of the deposit building a basis for an updated PEA that would include both oxide and sulfide ore.

Zone 2000S

Zone 2000S, originally discovered in 2006 as the result of an IP survey, has the potential to add tonnage in the sulfide domain of resource category. The mineral resource on this zone is shown in Table 3, which was based on a 0.25% total copper grade cut-off.1 Six diamond drillholes were drilled in this zone are part of the first phase of drilling with the intent of evaluating the continuation of bornite-chalcopyrite mineralization down dip. The drilling was very successful in not only confirming the continuation of the high grade bornite-chalcopyrite mineralization but also extending mineralization well below the current block model as well as encountering significant molybdenite mineralization A technical hole (CRM21-018) was drilled subparallel to the mineralization to evaluate the geological concept of a southern W-E striking fault which post-dates and offsets mineralization.

Zone 13

Three diamond drill holes were completed in Zone 13 with the intent of evaluating the northern continuity of sulfide mineralization, along strike and to infill an open area of the block model. Within 1000m of Zone 1, Zone 13 has the potential to add both oxide and sulfide resources to an updated mine plan. The sulfide portion remains open along strike and at depth. All assay results from Zone 13 are pending.
