VANCOUVER, BC / ACCESSWIRE / January 10, 2023 / Granite Creek Copper Ltd. (TSXV:GCX | OTCQB:GCXXF) (“Granite Creek” or the “Company“)is pleased to report positive metallurgical results in support of the upcoming Preliminary Economic Assessment (“PEA”) for the Carmacks copper-gold-silver project (“the Project” or “Carmacks Project”) located in the Minto copper district, within the traditional territories of the Little Salmon Carmacks First Nation and the Selkirk First Nation, Yukon Canada.
Metallurgical testing completed by SGS Vancouver Metallurgy (“SGS”) supports a simplified process consisting of froth flotation for the recovery of copper, gold and silver from both sulphide and oxide ores at Carmacks. These tests demonstrate outstanding recovery levels and concentrate grades in both the sulphide only and blended sulphide/oxide samples, which would be utilized by the mine. Testing was done on samples consisting of material in which copper was present primarily in oxide minerals, where the copper was present as primarily sulphide minerals, and samples that were a blend of oxide and sulphide minerals. Table 1 below highlights selected results from this testing:

Locked cycle flotation on blend sample consisting of 60% sulfide and 40% oxide.
The sulphide ore assayed 0.92% Cu, 0.67% S, and 0.24 g/t Au. Gold and copper head grades calculated from the flotation test assays agreed well with the direct head assays.
The oxide ore assayed, 0.60% Cu, 0.06% S, and 0.25-0.82 g/t Au indicating that nugget gold may exist. However, the gold head grade calculated from the flotation tests was consistently between 0.20 g/t to 0.23 g/t with an average of 0.21 g/t. Locked cycle testing was not completed on the oxide samples.
Test work produced a very clean, premium, high-grade concentrate that forms the metallurgical basis for the process flow sheet of the PEA, which the company expects to publish by the end of the current quarter. Flotation optimization and an economic evaluation of the target copper grade versus recovery has been recommended by SGS and will be considered in future test work.
President and CEO, Tim Johnson, stated, “Building on the success of sulphide flotation testing completed in 2021, this study directly supports the PEA allowing a simplified flow sheet consisting of well-established froth flotation technology to be considered for increased overall recoveries at the Carmacks Project. Metallurgy is a key component of the upcoming PEA and with this important work complete we look forward to delivering the updated study to the market within the current quarter.”

VANCOUVER, BC / ACCESSWIRE / November 22, 2022 / Granite Creek Copper Ltd. (TSXV:GCX)(OTCQB:GCXXF) (“Granite Creek” or the “Company“) is pleased to announce results from an Induced Polarization (“IP”) survey conducted on the Company’s 100%-owned Carmacks copper-gold-silver project (“Carmacks” or the “Deposit”) in the Minto Copper District of central Yukon, Canada. The large, highly prospective, potential resource expansion targets identified adjacent to or near the proposed open pits warrant follow-up exploration in upcoming campaigns. The Company further announces it has closed the second and final tranche of the private placement financing described in a news release dated October 5, 2022.
President & CEO, Tim Johnson, stated, “These multiple new zones and targets adjacent to the conceptual open pits, as defined by the March NI 43-101 Mineral Resource Estimate update, further highlight the prospectivity of our Carmacks project. Our team continues to do excellent work at Carmacks and we are confident in our ability to expand known mineralization and make new discoveries in the lesser explored parts of the 176km2 project. The current focus is the completion of the upcoming PEA and we look forward to reporting on the robust economics of the Carmacks project in the near term.”
Survey Overview
The first survey line (Line 1100S) was conducted over Zone 147 to investigate the correlation between known copper sulphide mineralization and the chargeability response from the Simcoe Geophysics deep-penetrating IP survey (see Figure 2 below). Subsequent survey lines were conducted over near-deposit target areas.
The results of the survey were enhanced by Resistivity Scaled Chargeability (“RSC”). RSC is a ratio of chargeability to resistivity (electrical properties measured by the IP survey) with the applied ratio determined by comparing various ratios to known mineralized bodies. The well-defined Zone 147 was used as a model to determine the RSC ratio that best fit the known mineralization. (See Figure 4 below).
Figure 1 – Carmacks Copper-Gold Project Location
Granite Creek Copper Ltd., Monday, November 21, 2022, Press release picture
Line 1100S, surveyed over defined sulfide copper mineralization in Zone 147, established a model for the RSC response and identified a new zone ~920 meters to the west. This new zone, named the Sourtoe Zone, extends 200m south to Line 1300S. This zone has been investigated with soil samples and trenching, exposing visually mineralized material close to surface (results pending). The soils and trenching were designed to evaluate the geochemical and geological signatures of this near-surface IP response and their similarities to known mineralized zones.
Figure 3 – 2022 IP Survey Line 1100S
Granite Creek Copper Ltd., Monday, November 21, 2022, Press release picture
Line 1300S shows a potential continuation of the Sourtoe Zone, giving the zone a minimum of 200m strike length as well as a new, deeper target, the 147 Deep Target, several hundred meters below the proposed 147 pit.
Figure 4 – 2022 IP Survey Line 1300S
Granite Creek Copper Ltd., Monday, November 21, 2022, Press release picture
Line 1500S, designed to test the gap area between zones 2000 and 147 (the “Gap Zone”), was successful in identifying a significant anomaly that is offset to the west from both zones. 3D modeling of historic drilling shows that this target has not been drill tested and could represent a southern extension of the 147 zone. The Gap Zone Target is a top candidate for additional near-deposit exploration (See figure 4). Additionally, a new, deeper target area that appears on this line and extends to line 1700S has been identified as the 58 Target.
Figure 5 – 2022 IP Survey Line 1500S
Granite Creek Copper Ltd., Monday, November 21, 2022, Press release picture
Line 1700S, located 200m south of Line 1500S, shows the probable Gap Zone Target continuing southwards towards Zone 2000 as well as the newly identified 58 Target. Additionally, a shallow anomaly east of the proposed pit is identified as a possible continuation of Zone 4 proximal to the 147 pit.
Figure 6 – 2022 IP Survey Line 1700S
Granite Creek Copper Ltd., Monday, November 21, 2022, Press release picture
Line 3300S, the southern most line completed in this survey highlights the potentiality of the area underneath the proposed 1213 pit. Additionally, an anomaly on the western portion of the line has been identified as 1213 west target for further follow up. With the current pit design bottoming out at 180 meters there remains significant room to grow the resource in this area. Additional lines on 200m spacing over the 1213 area are planned for subsequent geophysical campaigns to further define the zone.

VANCOUVER, BC / ACCESSWIRE / August 24, 2022 / Granite Creek Copper Ltd. (TSXV:GCX | OTCQB:GCXXF) (“Granite Creek” or the “Company“) is pleased to announce the acquisition of the Star Cu-Ni-Platinum Group Metal (“PGM”) project, located in the Omineca mineral belt of northern British Columbia.
Granite Creek will secure a 100% interest in the Star project, with no underlying royalty or further obligation, for a total consideration of $10,000 CDN and the issuance of 500,000 common shares of the Company to the estate of Ursula Mowat. The issued shares will have a hold period of 4 months plus one day from the date of issuance. The Company anticipates closing the transaction on or about the August 30, 2022, subject to TSX Venture approval.
Tim Johnson, CEO of Granite Creek Copper, stated, “I was saddened to hear of the passing of Ursula Mowat who had been a pioneer in prospecting for platinum group metals and associated nickel and copper mineralisation in the Omineca region of British Columbia. As one of the first geologists to recognize the potential for the native iron-nickel alloy awaruite to be a significant source of low-cost nickel in the Omineca area, she will be remembered for her ground-breaking work in the industry. To be able to acquire the Star project claims and continue the development work to unlock the potential that Ursula obviously saw is an honour. We look forward to completing our initial work on the claims and relaying to investors the potential for both precious and battery metals on the project.”
“Although Granite Creek’s primary focus remains our flagship Carmacks Copper-Gold-Silver project with the pending updated preliminary economic assessment expected in Q4 2022, the Star project increases our exposure to critical minerals at a time when the Canadian government is incentivizing exploration of listed critical commodities in Canada, as part of a broader push to secure supplies of the minerals in North America for national security and to support the development of carbon free energy sources.”
About the Star Project
The Star project is located 190 kilometers northeast of Smithers, BC and is within 5 kilometers of the Omineca Resource Road and powerline that served the Kemess Mine. The 2500-hectare project is underlain by ultramafic rocks that are prospective for copper, nickel, cobalt, PGMs and gold. Previous work identified multiple showings consisting of copper and nickel sulphide mineralisation with accompanying PGM and gold values. The showings are identified within six distinct zones spread over a 12-kilometer strike length including Queen Zone, GL Zone, HB Zone, HC Zone, Libra Zone, and Ridge Zone (see accompanying Figure 1 for Zone locations as well as additional areas identified for follow up).
Highlights of some of the best mineralised copper and nickel sulfide bearing rock sampled by Ms. Mowat from the various are identified below:
1.18% Cu, 0.17 g/t Au, 0.11 g/t Pd from the Queen Zone
0.78% Cu, 0.25% Ni, 833 ppm Co and 0.27% Cu from the GL Zone.
0.09 % Cu, 1.32 g/t Pt and 1.82 g/t Pd from the HB Zone.

VANCOUVER, BC / ACCESSWIRE / May 3, 2022 / Granite Creek Copper Ltd. (TSXV:GCX)(OTCQB:GCXXF) (“Granite Creek” or the “Company“) is pleased to announce that it has retained SGS to complete an updated Preliminary Economic Assessment (“PEA”) on the Carmacks project. The PEA will use the 2022 Resource Estimate (Table 1), consisting of 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 as the main input. Building off a 2017 PEA(1), the updated study will encompass the following:
Significant Increase in Contained Copper – The 2022 resource estimate marked a 43% increase in contained copper over the previous estimate referenced(2)
Inclusion of Sulphide Processing – As of the publication of the 2022 resource estimate the Carmacks project consists of roughly 50/50 sulfide and oxide resources by contained metal. The Company sees the inclusion of sulphide resources as a significant potential value driver having a positive impact on the economics of the project; and
High Proportion of Resources Modeled in Three Conceptual Open Pits – 96% of the 2022 resources are contained within the conceptual pits (Figure 1). With a high percentage of current resources reporting in conceptual pits the cash cost per pound of copper is expected to be significantly lower when compared to a similar sized underground operation.
Timothy Johnson, Granite Creek President & CEO, stated, “The launch of the updated Preliminary Economic Assessment study marks a major milestone in the development of the Carmacks deposit at a time when commodities demand is seeing rapid growth. The Carmacks project is well-positioned by its location, access to infrastructure, and proximity to the operating, high-grade Minto mine just to the north. Both copper and molybdenum have been deemed by the Canadian government to be ‘critical minerals‘ based on their role in the transition to a low-carbon economy which we expect will provide prolonged price strength well into the future. We look forward to continuing to bring positive news as we develop this high-grade copper project.”

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.
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.

This news release includes certain statements that may be deemed “forward-looking statements”. All statements in this release, other than statements of historical facts including, without limitation, statements regarding potential mineralization, historic production, estimation of mineral resources, the realization of mineral resource estimates, interpretation of prior exploration and potential exploration results, the timing and success of exploration activities generally, the timing and results of future resource estimates, permitting time lines, metal prices and currency exchange rates, availability of capital, government regulation of exploration operations, environmental risks, reclamation, title, and future plans and objectives of the company are forward-looking statements that involve various risks and uncertainties. Although Granite Creek Copper believes the expectations expressed in such forward-looking statements are based on reasonable assumptions, such statements are not guarantees of future performance and actual results or developments may differ materially from those in the forward-looking statements. Forward-looking statements are based on a number of material factors and assumptions. 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. Accordingly, the actual events may differ materially from those projected in the forward-looking statements.
