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.

Granite Creek Copper Announces Results of Mine Planning & Mineral Processing Work Conducted on the Carmacks Copper-Gold Project by Sedgman and Mining Plus

VANCOUVER, BC / ACCESSWIRE / December 1, 2021 / Granite Creek Copper Ltd. (TSXV:GCX)(OTCQB:GCXXF) (“Granite Creek” or the “Company“) is pleased to announce the results of work completed by Sedgman Canada and Mining Plus on the Company’s Carmacks copper-gold-silver deposit in the Minto Copper Belt located in central Yukon, Canada. The Company has received a final report on studies that include review of alternate leach technologies, mine planning, ore sorting and other key elements which are expected to be highly influential on the updated preliminary economic assessment (“PEA”) planned for H1 2022.

Highlights include:

  • Excellent results from initial metallurgical testing on sulfide material;
  • Confirmation of in tank leaching as the preferred method of extraction of both copper and precious metals from oxide ores;
  • Identification of conventional flotation as the preferred method of producing a copper concentrate from sulfide ores;
  • Development of a draft underground mine plan, with sub-level block cave as the preferred underground mining method at Carmacks;

Granite Creek President & CEO, Tim Johnson, stated, “We are extraordinarily pleased with the results provided by Sedgman and Mining Plus and the degree of efficiency, expertise and professionalism they have demonstrated since Granite Creek initially engaged them in May of this year. The studies have provided a great deal of new insight and clarity on the best path forward as we continue to advance Carmacks toward updated economics and, ultimately, production. We are very confident that these elements of mine planning and optimization, combined with the updated 43-101 mineral resource estimate we anticipate in Q1, will form the basis of a robust new PEA. The Yukon is an exceptional mining jurisdiction, the Minto belt has excellent infrastructure and robust mineralization currently being mined by Minto Metals Corp. just to the north of us who are now publicly traded on the Venture Exchange. We look forward to additional announcements soon as the pieces continue to fall into place at Carmacks.”

Virtual Investor Conference – OTC Markets Group

Granite Creek will be presenting at the upcoming Mining & Metals Virtual Investor Conference hosted by OTC Markets Group on Wednesday, December 8th at 11:30 AM PT / 2:30 PM ET. Topics of discussion will include the Company’s 2021 drilling campaign, the mine planning and mineral processing results described herein, and implications for the expected updates to both the existing 43-101 mineral resource estimate and PEA. To register, click here.

Sedgman / Mining Plus Report Discussion

An initial review of geotechnical studies as referenced in the 2017 PEA1,2, has indicated that a sub-level block cave is likely the most cost-effective method of underground mining of Zone 1 at the Carmacks Deposit. Based on this, Granite Creek will now move to initiate costing studies to support an updated PEA that includes potential underground resources not only in Zone 1 but other adjacent zones. In addition, the Company will launch pit design and optimization efforts on mineralized zones that lie outside of the pit contemplated in the 2017 PEA. Specifically, Zones 2000S and 13 will see pit optimization scenarios that will determine how much material could potentially be mined via open pit and what portion of the resources will be extracted by underground mining methods.

Metallurgical testing of sulfide mineralization to determine recovery of copper minerals using conventional flotation technology to create a copper concentrate was highly successful, achieving copper recoveries of up to 95%. Further testing is planned to confirm these recovery rates and to add gold and silver to a concentrate scenario. This work will be used identify the correct sizing of a copper-gold-silver concentrator circuit and the associated economics.

Previous economic assessments did not consider the potential value from processing of the high-grade sulphide material at Carmacks, despite a defined sulfide resource. In conducting a comprehensive review of the Carmacks deposit and the Carmacks North target area, the presence of significant sulfide mineralization became immediately apparent and Granite Creek felt it prudent to examine its potential inclusion as a means to expand the overall resource, extend mine life and improve economics. The majority of the Company’s 2021 drilling campaign focused on delineating and expanding sulfide resources with both near surface and deeper targets explored. Both oxide and sulphide mineralized zones remain open to expansion, with a significant expansion of the sulphide resource anticipated in the upcoming resource estimate update in Q1 2022. The updated PEA will incorporate this expanded resource and will include review of the mining sequence including an assessment of whether any sulfide resources may be mined via open pit and the optimal sequence for sulfide flotation and oxide leaching.

On November 8th the Yukon government announced the following road construction update that directly effects Granite Creek’s Carmacks Project.

“Whitehorse based company Pelly Construction has been awarded the contract for the Carmacks Bypass Project, a $29.6 million investment to construct a new road and bridge near Carmacks. This project is a key component under the Yukon Resource Gateway Program and a collaborative effort between the Government of Yukon and Little Salmon/Carmacks First Nation.

The project, which is anticipated to be complete in 2024, will allow industrial vehicles to bypass the community of Carmacks, creating an enhanced and safer flow of traffic for residents. It will also improve access to mining activities while enabling the Little Salmon/Carmacks First Nation to benefit from contracting, education and training benefits associated with the project.

The Yukon Resource Gateway Program improves infrastructure to Yukon’s most mineral-rich areas. The Carmacks Bypass project is jointly funded by Canada and the Yukon and is the first project to be awarded under the program.”

Granite Creek President & CEO, Tim Johnson, commented, “We are very pleased to have engaged with a top calibre firm like SGS on this key milestone in the Company’s relatively short history. With the amount of highly targeted new drilling we have completed, we anticipate a robust update to the existing resource estimate and that this, along with the mine planning and trade-off studies being developed by Sedgman and Mining Plus, will have a significant impact on the project economics. In our continuing development of Carmacks, the recent announcement by the Yukon government of the start of construction on the Carmacks Bypass is extremely good news. The incremental improvement in access represented by this road upgrade is welcomed and this, combined with an updated resource estimate, will pave the way for and even more extensive exploration program in 2022.”

Granite Creek Copper Holds $2.5 Billion Worth of Copper

Bob Moriarty

Nov 4, 2021

Granite Creek Copper (GCX-V) has 100% ownership of a 176 square km copper/gold/silver property named the Carmacks project located in the Minto Copper Belt in the Yukon. The high-grade copper project is on trend with the Minto copper mine. We shall see why that is very important to the future of the company shortly.

The project had completed a 43-101 in 2018 showing an M&I resource of 23.76 MT of 0.85% Cu, 0.31 g/t Au and 3.41 g/t Ag. A 12,000-meter drill program has been completed in 2021 directed at expanding the resource and converting inferred sulphides material to M&I. An updated 43-101 is expected in early 2022 based on results from the 2021 program. In addition there will be an updated PEA in the first half of 2022 to include both oxide and sulphide material.

At today’s price of copper, that 43-101 resource is worth $104.26/tonne in the ground. Naturally copper going any higher will make this project far more desirable. As we see from the ongoing COP26 conference there seems to be a general agreement that the world needs to reduce its carbon footprint by using more “Green Energy.”

Well, Green Energy requires enormous quantities of copper, lithium and graphite, far more than today. The world is short of copper now and is going to run even shorter. Prices will have to go up. Granite Creek Copper is in the catbird’s seat ready to move to production.

As I mentioned above Minto Exploration is important to GCX for several reasons. Minto is about to build a mill and is in the process of going public imminently. Minto has only three years reserves at presently planned production. In their financing pitch deck they clearly refer to GCX with references to potential M&A activities within the Minto Copper Belt. Guess whom they are talking about?

A week ago Granite Creek released the final results from the Phase 1 of three different phases. The Phase 1 program was designed to add sulfide tonnage to the existing oxide resource. It consisted of 19 diamond core drill holes and totaled 6355 meters. Results from the Phase 2 and Phase 3 programs are still in the lab. Phase 2 did 20 RC holes and about 3000 meters in total. Phase 3 was using the diamond core rig again and did about 2700 meters.

Granite Creek is a really easy call. As of today the company has a $22 million market cap with $1 million in cash and $500,000 in callable warrants. In addition there are a bunch of $.15 warrants expiring in January 2022 so the company is well cashed up.

I’m not a big expert on copper but Granite Creek has to be one of the lowest market cap copper stories with a real asset. When Minto goes public and goes into production, I am certain they will pay attention.

Granite Creek is an advertiser. I have participated in the last private placement so naturally I am biased. Do your own due diligence.

Granite Creek Copper Reports Final Results from Phase 1 of 2021 Drill Program, Including 23.30 Meters of 2.27 % Copper Equivalent, at the Carmacks Copper-Gold-Silver Project in Yukon, Canada

VANCOUVER, BC / ACCESSWIRE / October 28, 2021 / Granite Creek Copper Ltd. (TSX.V:GCX | OTCQB:GCXXF) (“Granite Creek” or the “Company“) is pleased to announce the third and final tranche of assay results from Phase 1 of the Company’s three-phase 2021 drill program at the 100%-owned Carmacks project.

The Phase 1 campaign focused on expansion and upgrade of resources in zones 1, 2000S, and 13 by testing the sulfide potential of these priority areas. In addition to the Phase 1 program, the Company also completed Phase 2 RC drilling at early-stage targets, and a Phase 3 diamond drill program to follow up on the success of Phase 1. All activity has been completed at site for the 2021 field season with assays for Phases 2 and 3 pending.

Granite Creek President & CEO, Tim Johnson, commented, “We are extremely pleased with the results of our 2021 exploration program which achieved many of our objectives and exceeded our expectations in several important respects. We expanded sulfide mineralization in three of the main zones at Carmacks which will be reflected in an updated NI 43-101 resource estimate followed by a new mine plan which is being developed to incorporate both oxide and sulfide material. We anticipate the sulfide resources could make a significant difference to the mine life and economics of the Carmacks deposit and we look forward to further defining that potential.”

Highlights

  • In Zone 1, diamond drill hole CRM21-019 intersected 67.35m of 1.23% Copper Equivalent (“CuEq”) mineralization including 23.30m of 2.27 CuEq.
  • In Zone 1, diamond drill hole CRM21-013 intersected 67.90m of 0.90% CuEq including 22.88m of 1.14% CuEq and 12.91m of 1.73% CuEq.
  • In Zone 13, diamond drill hole CRM21-021 intersected 96.85m of 0.84% CuEq including 35.85m of 1.04 CuEq and 21.35m of 1.21 CuEq.
  • Granite Creek believes these intercepts, plus others listed in the table below, have the potential to increase the grade and confidence of the resource model in Zone 1 and increase the grade and total size of Zones 2000S and 13.
  • Updated resource model being developed.

Figure 1 – Carmacks Copper Project Plan View

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 down-dip continuation of the inferred resource. 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 sulfide resource in this zone. Of the total reported meterage with significant mineralization, 67% returned mineralized intercepts grading greater than those reported in the inferred category of the resource estimate completed in 2017. While only preliminary, the Company feels that these intercepts have the potential to significantly increase the grade and the confidence in this area of the resource model.

While the Preliminary Economic Assessment (“PEA”) published in 2017(1,2) looked only at the oxide material in Zones 1,4, and 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, to build a basis for an updated PEA that would include both oxide and sulfide ore.

Zone 2000S

Zone 2000S has the potential to add tonnage in the sulfide domain of resource category and in doing so could add significant value to an updated PEA that included sulfide resources. During Phase 1, six diamond drillholes were drilled in this zone to evaluate the continuation of bornite-chalcopyrite mineralization down dip, and two additional holes were drilled during Phase 2 with assays still pending. Drill hole CRM21-011, along with all other drillholes from the 2021 program (see release dated August 22, 2021) extended known mineralization in the zone from 30m to 100m below the current block model. CRM21-018, a technical hole drilled subparallel to the mineralization to evaluate the geological concept of a southern W-E striking fault, was successful in locating the fault and extends mineralization to depth beneath the current resource model

Zone 13

Three diamond drill holes were completed at Zone 13 in Phase 1, and an additional two holes were completed in Phase 3 with the intent of evaluating the northern continuity of sulfide mineralization, and infilling an open area of the block model. Building on success from the company’s inaugural drill program in 2020 which included 127 metres of continuous copper mineralization in drillhole CRM20-001, grading 0.85% CuEq and including 28.65m of 1.74% CuEq and 19.2m of 1.19% CuEq (see news release dated February 11,2021), all five diamond drill holes were successful in extending and infilling mineralization from Zone 13 in the Carmacks deposit including CRM21-021 which intercepted 96.85m grading 0.84% CuEq including 35.85m of 1.04% CuEq and 21.35m of 1.21% CuEq. Drill hole CRM21-020 drilled from the same pad as CRM21-021 deviated from planed direction and was not completed.

Granite Creek Copper Receives Positive Metallurgical Results at Carmacks Copper-Gold Project in Yukon, Canada

VANCOUVER BC / ACCESSWIRE / October 14, 2021 / Granite Creek Copper Ltd. (TSXV:GCX)(OTCQB:GCXXF) (“Granite Creek” or the “Company“) is pleased to announce the receipt of positive results from metallurgy testing completed on sulfide mineralized core samples from the Company’s Carmacks project.

Testing was completed as part of trade-off studies now underway under the direction of Sedgman Canada and Mining Plus with the objective of developing the basis for an updated Preliminary Economic Assessment (“PEA”) on the project. Two representative samples of copper sulfide material and one sample of copper oxide material were delivered to Bureau Veritas Commodities, Metallurgy Division, for rougher flotation kinetic testing and open cleaner flotation testing. The purpose of the testing was to determine how amenable the sulfide mineralization present at the Carmacks deposit was to concentration by flotation, what recoveries could be expected, and to lay the groundwork for further testing. A preliminary copper flotation recovery model was generated at a fixed 25% copper concentrate grade with test results as summarized below:

  • Recoveries of greater than 95% for copper into a 25% copper concentrate are possible.
  • Copper sulfide minerals are well-liberated for rougher recovery via flotation at P80 of 150 µm.
  • A secondary regrind size at P80 of 25 µm can achieve 25% copper grade and high cleaner stage recovery.
  • Gold is associated primarily with copper sulfide minerals and minor pyrite. Flotation of gold with copper concentrate is likely the most economical way to recover gold.
  • High chalcopyrite content as the copper mineral and low pyrite content within the samples indicate a simple reagent scheme and relatively easy copper flotation upgrade.

The preliminary tests indicate that well-established flotation methods with known reagents will likely be the preferred processing method for sulfide material at Carmacks. The next stage of metallurgical test work will involve greater variability of samples to validate copper and gold recoveries as well as assessing potential levels of silver and molybdenum recoveries.https://s.yimg.com/rq/darla/4-9-0/html/r-sf-flx.html

Granite Creek President and CEO, Tim Johnson, commented, “These initial metallurgical results are very encouraging and are an important step in bringing the sulfide resources present at the Carmacks deposit into an updated mine plan and PEA. The Company’s belief in, and focus on, the copper sulfide potential at Carmacks and Carmacks North is being validated and advanced with every phase of work completed. We look forward to continuing to roll out the Carmacks story with substantive news flow throughout the remainder of the year and into 2022, including drill results from the recently completed, three-phase 2021 campaign.”

Factors that could cause actual results to differ materially from those in forward-looking statements include failure to obtain necessary approvals, unsuccessful exploration results, changes in project parameters as plans continue to be refined, results of future resource estimates, future metal prices, availability of capital and financing on acceptable terms, general economic, market or business conditions, risks associated with regulatory changes, defects in title, availability of personnel, materials and equipment on a timely basis, accidents or equipment breakdowns, uninsured risks, delays in receiving government approvals, unanticipated environmental impacts on operations and costs to remedy same, and other exploration or other risks detailed herein and from time to time in the filings made by the companies with securities regulators. Readers are cautioned that mineral resources that are not mineral reserves do not have demonstrated economic viability. Mineral exploration and development of mines is an inherently risky business.

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
