VANCOUVER, BC / ACCESSWIRE / December 10, 2024 / Granite Creek Copper Ltd. (TSXV:GCX)(OTCQB:GCXXF) (“Granite Creek” or the “Company”) is pleased to announce drill results from the 2024 drill campaign on at its wholly owned Carmacks copper-gold-silver project located in central Yukon, Canada. As previously mentioned, the Company identified a new zone within the Carmacks project called the Gap Zone (see news release dated October 3, 2024), located between existing high-grade, pit-constrained resources. The exploratory drill program intercepted copper mineralization in all four drill holes, laying the foundation for a follow-up resource definition and expansion drilling campaign. See below for selected drill results.

The Gap Zone lies between the proposed 147 and 2000S pits and was first identified by a 2022 geophysical IP survey (see news release dated November 21, 2022). Likely representing a fault offset from the main 147 Zone, the Gap Zone has the potential to add significant tonnage and extend the mine life envisioned by the 2023 Preliminary Economic Assessment (see news release dated January 19, 2023)

Granite Creek President and CEO, Timothy Johnson, stated, “The success of this drill program highlights the continued prospectivity of the Carmacks project. There remain multiple untested drill targets on the project, both proximal to the proposed pits as outlined int the 2023 PEA, as well as distal areas and across the northern sector which has seen only modest exploration. The project hosts significant copper-gold-silver resources and has the potential for major expansion across the 177 square kilometre land package in this top mining jurisdiction.”

Carmacks Deposit

The 177 sq km, Carmacks project contains over 824 Mlbs Measured and Indicated and 29 Mlbs Inferred copper equivalent (“CuEq”) metal within a National Instrument 43-101-compliant, high-grade resource of 36.2 million tonnes grading 1.07 % CuEq (0.81% Cu, 0.31 g/t Au, 3.41 Ag)¹. The road accessible project is located along the Freegold Road, a Resource Gateway Road currently being upgraded by the Yukon government and is within 20 km of the Yukon electrical grid. The project is also situated within the Minto Copper Belt, a roughly 80 km long belt of rocks known for high grade occurrences of copper-gold-silver mineralisation.

The 2023 Carmacks Preliminary Economic Assessment (“PEA”), completed by SGS Canada, identified increased resources along with improved recovery as prime means of increasing the Net Present Value (“NPV”) of the project. Work completed this year by Kemetco Research (see news release dated January 17, 2024) demonstrated that recoveries exceeding the target outlined in the PEA can be achieved. The just completed drill program was designed to show that significant resource expansion is possible and specifically targeted areas that could lead to an expanded mine life as envisioned by the PEA.

VANCOUVER, BC / ACCESSWIRE / October 3, 2024 / Granite Creek Copper Ltd. (TSXV:GCX)(OTCQB:GCXXF) (“Granite Creek” or the “Company”) is pleased to announce that the now completed 2024 drill campaign on at its wholly owned Carmacks copper-gold-silver project located in central Yukon, Canada yielded the discovery of a new mineralized zone.

The drill program consisted of 1420 metres in four drill holes, designed to test new targets adjacent to existing high-grade, pit-constrained resources, and was successful in locating and partially delineating the Gap Zone. The newly discovered zone was traced for approximately 170 meters and remains open along strike and at depth, with copper mineralisation observed in three of four drill holes. The Gap Zone lies between the proposed 147 and 2000S pits and was first identified by a 2022 geophysical IP survey (see news release dated November 21, 2022). Likely representing a fault offset from the main 147 Zone, the Gap Zone has the potential to add significant tonnage and extend the mine life envisioned by the 2023 Preliminary Economic Assessment (see news release dated January 19, 2023)

Mineralized sections have been sampled and delivered to the lab for analysis with results pending. Observed mineralization and host rocks were similar in appearance to known ore zones on the property.

VANCOUVER, BC / ACCESSWIRE / January 17, 2024 / Granite Creek Copper Ltd. (TSXV:GCX)(OTCQB:GCXXF) (“Granite Creek” or the “Company“) is pleased to announce significantly increased recovery of copper from oxide material at its Carmacks Copper-Gold-Silver project (“Carmacks Project” or the “Project“) was achieved through metallurgical studies conducted by Kemetco Research Inc. from (“Kemetco“).

The Company’s 2023 Preliminary Economic Assessment (“2023 PEA”) for the Project identified the opportunity to significantly increase net present value (“NPV”) by improving oxide recovery. Metallurgical testing completed on the project in support of the 2023 PEA showed that while a copper recovery of over 93% could be achieved via a well-established froth flotation technique for sulphide ore, only 39.8% copper recovery from oxide ore was achieved using the same process (see Table 1 for summary of flotation results). The current test results show a total recovery of 88% for oxide material is possible, an increase of 48% over the PEA base case (Tables 1 and 2). These results will have a significant impact on the economics for the project as the PEA identified an additional $180 M of NPV^5% value by increasing life of mine average recovery for copper from 64% to 77%. With sulfide recoveries of 93.7% identified in the PEA and combined oxide recoveries (initial flotation + leaching and precipitate) of 88% the potential recoveries for copper are well above the 77% target level highlighted in the 2023 PEA.

The current mine plan as outlined in the 2023 PEA contemplates processing material with a high oxide content of up to 80% oxide ore in the first five years of the mine life. During this time over 8.4 million tonnes of oxide material would be processed versus 2.88 million tonnes of sulphide material. An increase in recovery of oxide material for the first five years of mine life, as demonstrated in these test results, would have a potentially very significant impact on project economics.

Kemetco Research Inc. was retained to complete testing on tailings produced in previous metallurgical work to develop a process for treating material that will have passed through the mill and still have significant oxide copper minerals present (See Figure 1 for simplified flow sheet). This laboratory test program showcased the efficacy of copper recovery from Carmacks copper oxide flotation tailings through a low-concentration acid leach at ambient temperature and pressure followed by chemical precipitation of copper minerals. The precipitation of copper sulphide (“CuS”) from the resulting leachate was shown to be an effective method of fully recovering the leached copper from solution, yielding a very high-grade CuS precipitate that would be added to the copper concentrate further increasing the copper grade of the high-quality concentrates from the project. For reference the PEA estimated an average concentrate grade of 40% copper with significant gold and silver credits.

Figure 1: Simplified Flow Sheet

Results of this testing are outlined below:

• Acid leaching was able to extract as much as 80% of the remnant copper present in a composite prepared from Carmacks copper oxide flotation tailings.
• Copper in precipitates varied, but in most tests approached the theoretical grade of pure CuS which grades 66.5% Cu. High grades were obtained without pH adjustment.
• This testing shows a total copper recovery from oxide material of 88% with Initial Flotation recovery of 39.8% + Leach and Precipitate recovery of 48% (80% of the remnant copper).
• Adding Sodium hydrosulphide (“NaHS”) solution resulted in up to 100% precipitation of copper from leach solutions, offering a promising avenue for further refinement. Hydrogen sulphide gas was equally effective as a sulphide source for copper precipitation.
• In all tests, the precipitation of CuS resulted in a drop in pH as free acid was regenerated as a by-product of the precipitation reaction, creating the potential to reuse/recycle the regenerated acid.

About the Carmacks Deposit:

The road accessible Carmacks deposits hosts a NI 43-101 resource consisting of 36.2 Mt M&I, grading 1.07% CuEq 0.81% Cu, 0.31 g/t Au, 3.41 g/t Ag (see news release January 19, 2023). The deposit was the subject of a positive PEA released in January 2023 that envision a 9-year mine life based on a mill capable of processing 7,000 t/d of combined oxide and sulfide ore. The resources are contained within three conceptual open pits and are open for expansion.

Contained Copper in Measured and Indicated Resources

147 Pit 280 Mlbs copper in oxide
126 Mlbs copper in sulfide

2000 Pit 10.5 Mlbs copper in oxide
51.3 Mlbs copper in sulfide

1213 Pit 35.4 Mlbs copper in oxide
122.3 Mlbs copper in sulfide

Tim Johnson, President & CEO stated, “The 2023 PEA, a major milestone for the Company, identified several opportunities for the Project including increased recovery, resource expansion and additional mine and process optimisation. The unlocking of additional value through the improved oxide recovery that this testing represents, especially in the early years of mine life, has the potential to add significantly to the NPV of the project. These results could allow for re-evaluation of resources that didn’t make it into the mine plan due to lower grades or assumed recoveries. The process being developed by the company also has the possibility of being used in other parts of the Minto Copper belt where oxidized or partially oxidized (POX) copper ores have not been processed by other operators.”

VANCOUVER, BC / ACCESSWIRE / August 23, 2023 / Granite Creek Copper Ltd. (TSX.V:GCX)(OTCQB:GCXXF) (“Granite Creek” or the “Company“) is pleased to announce the preliminary results of a metallurgical study designed to increase recovery of copper from oxide material at its Carmacks Copper-Gold-Silver project (“Carmacks Project” or the “Project“)

Kemetco Research Inc. (“Kemetco”) has been contracted to carry out an initial series of scoping tests to evaluate the potential for extraction and recovery of copper from unrecovered copper oxide minerals in Carmacks Project flotation tailings as referenced in the Company’s 2023 Preliminary Economic Assessment (“2023 PEA”) ^*. Testing involves the leaching of tailings from previous flotation testing of oxidised copper material to dissolve copper into solution and subsequently precipitate copper in a form that could be added to a concentrate being produced by sulphide flotation. The leaching portion of the test work has now been completed with up to 81% of the copper present in the test samples going into solution. The remaining project task, currently underway at Kemetco, is to complete a series of bench tests to evaluate methods for selective recovery of the leached copper from solution. The planned tests will focus on copper sulphide precipitation to target generation of a high-grade copper sulphide product that could potentially be combined with a copper flotation concentrate in an overall production flowsheet, resulting in significant potential increases to both overall copper recovery and the copper grade of the final concentrate product.

The 2023 PEA was based on an average recovery of copper, life of mine (“LOM“) of 64%, with up to 93.7% recovery of copper when processing sulfide material but only 39.8% when processing oxide material. The current mine plan as outlined in the 2023 PEA contemplates processing material with a high oxide content of up to 80% oxide ore in the first five years of the mine life during which time over 8.4 million tonnes of oxide material would be processed versus 2.88 million tonnes of sulphide material. Sensitivity analysis completed in the 2023 PEA identified over $180M of Net Present Value (“NPV“) to be gained from a combined sulphide-oxide recovery system by increasing the LOM recovery of copper by 20% from the current projected 64% to 77% total copper recovery.

The material used for the current test consists of tailings from flotation testing of oxide material, where 39.8% recovery of copper was achieved prior to the current leach testing. With up to 81% of the remaining copper going into solution an additional 48% recovery of copper in oxide is possible (81% of remaining 60.2% copper from original test sample) which would increase the total copper recovery of oxide material to over 80% (original 39.8% plus 48%). This could potentially provide a path to exceed the 20% increase in total LOM copper recovery opportunity, which was referenced in the 2023 PEA. While the current work is being conducted on the most representative material available, it should be noted that this work is preliminary in nature and has not yet been tested on a range of potential feed blends.

Tim Johnson, President & CEO stated, “The 2023 PEA, a major milestone for the Company, identified several opportunities for the Project including increased recovery, resource expansion and additional mine and process optimisation. The unlocking of additional value through the improved recovery that this testing represents, especially in the early years of mine life, has the potential to add significantly to the NPV of the project. These results could allow for re-evaluation of resources that didn’t make it into the mine plan due to lower grades or assumed recoveries. The process being developed by the company also has the possibility of being used in other parts of the Minto Copper belt where oxidised or partially oxidised (POX) copper ores have not been processed by other operators.”

BCSC continuous disclosure review.

Following a recent review of Granite Creek’s continuous disclosure by the British Columbia Securities Commission, the Company provides the following corrections:

In a news release dated January 19, 2023, announcing the completion of the PEA, the Company stated, “The PEA indicates that the potential economic returns from the Project justify advancing to a feasibility study”. This statement could be construed that the Company is treating the PEA as a pre-feasibility level study, which is not the case. While the Company maintains that the PEA was positive, additional work will need to be done before a full feasibility study could be initiated. The Company also wishes to retract to word “robust” when describing the economics of the Project as this may be misleading to some readers.

VANCOUVER, BC / ACCESSWIRE / March 23, 2023 / Granite Creek Copper Ltd. (TSX.V:GCX)(OTCQB:GCXXF) (“Granite Creek” or the “Company“) is pleased to announce it has entered into an agreement to acquire a 100% interest in the Lucky Ship molybdenum property (“LS Molybdenum Project” or the “Project”) from two arms length vendors. Under the terms of the agreement the Company has the option to acquire a 100% interest in the Project by issuing 3,750,000 shares over a three-year period and completing exploration work equivalent to two years worth of assessment credit during the first two years of the agreement and four years worth of assessment credit in the third year of the agreement to maintain the mineral claims in good standing.

The LS Molybdenum Project is located within the traditional territory of the Wet’suwet’en First Nation in central British Columbia and is in a region with a long history of mining including the Endako molybdenum mine, Huckleberry copper-molybdenum mine, Equity silver mine and others (see Figure 1 map below). The Project is accessible year-round along a well-developed network of forestry roads, with a high-capacity powerline within 50 kilometers, and paved highway and rail line access within 85 kilometers.

Tim Johnson, President and CEO, stated, “The addition of the LS Molybdenum project to our portfolio of critical minerals fits our strategy of value creation in the critical minerals space in safe political jurisdictions, focused on projects that show district scale potential and are under-explored. The LS Molybdenum project is complementary to our flagship PEA-stage Carmacks copper-gold-silver project where we have expanded the resource by 43% since acquisition and recently delivered a robust PEA in January 2023, highlighting the potential at that high-grade copper-gold-silver project. While we remain focused on advancing and expanding Carmacks, we see an excellent opportunity for creating significant shareholder value with the LS Molybdenum project during a time with few advanced stage molybdenum projects in the global pipeline and recent molybdenum prices trading at multi-decade highs due to the scarcity of supply in the market.”

Mr. Johnson, continued, “Molybdenum is an important critical mineral identified in the Canadian Critical Minerals Strategy used to strengthen steel and with a wide variety of other technical uses in the green economy for high strength – low weight applications such as wind turbines, electric vehicle components, and solar panels. These uses are expected to drive the demand for molybdenum in the coming decades with the International Energy Agency estimating there will be at least a 2.9X growth in the demand for molybdenum by 2040 in clean energy technologies to achieve their Sustainable Development Scenario (SDS)¹. Having a resource stage molybdenum asset in North America with potential to significantly grow puts Granite Creek in an excellent position to identify potential industrial partners in search of secure future supplies of molybdenum.”

About the LS Molybdenum Project

The LS Molybdenum project hosts a porphyry Mo deposit with a granite porphyry stock intruding a larger quartz-felspar porphyry stock in contact with older volcanic and sedimentary rocks. Mineralization occurs as a near-vertical ring of porphyry Mo style stockwork veining between 25 to 125 m in width around the margin of the interior granite porphyry stock. Mineralization remains open at depth with mineralization drilled to approximately 150 to 400 m in depth (see Figure 2 Cross section below). Porphyry Mo systems often have multiple porphyry centers and a number of additional targets remain to be tested.

The Project hosts a historical NI 43-101 molybdenum resource consisting of 65.66 million tonnes averaging 0.064% Mo containing 92.6 million pounds of Mo in the Indicated category with an additional 10.24 million tonnes averaging 0.054% Mo containing 12.2 million pounds Mo in the Inferred category. The Mineral Resource Estimate (“MRE”) was completed by A.C.A. Howe Int. Ltd with an effective date of May 1, 2008 and an amended date of June 30, 2008 to National Instrument 43-101 standards and is believed to be reliable. The resource was estimated using the inverse distance weighting (IDW²) interpolation technique, the search orientations and ranges of which were calculated through variographic analysis and consideration of the geological domain model. The Inferred and Indicated mineral resources were reported at a cut-off grade of 0.030% Mo. The full technical report entitled Technical Report on The Lucky Ship Molybdenum Project Morice Lake Area, Omineca Mining Division, British Columbia for Nanika Resources Inc. will be available on the Company’s website. It is currently available on SEDAR under the Goldbar Resource Incprofile (formerly Nanika Resources), filed July 2, 2008. The resource estimate was made public in a news release dated May 14, 2008 which is also available on SEDAR under the Goldbar profile.

The deposit was subject to a 2007 Preliminary Economic Assessment (“PEA”) completed by A.C.A. Howe Int. Ltd. The comprehensive PEA report has references to metallurgical recoveries, mineralization style, deposit geometry, proposed processing options and project sizing amongst others. The report, entitled Preliminary Economic Assessment of the Lucky Ship Molybdenum Project Morice Lake Area, Ominica Mining Division British Columbia for New Cantech Ventures Inc. is available on SEDAR under the Goldbar Resources Inc profile (formerly Nanika Resources), filed June 19, 2007.

The company cautions that it is not treating the PEA or the MRE as current mineral resources or reserves and the Company has not competed sufficient work to confirm either the MRE or the PEA. Any mention of the PEA or MRE are for reference only and the reports should not be relied on as current. For the company to treat the MRE as current additional work including, but not limited to, resampling, drilling and the implementation of the company’s own Quality Control and Quality Assurance (“QC/QA) program would need to be completed. The PEA would have to be updated in the context of current market conditions by an independent party to be considered current.

Carmacks Project Oxide Material Testing Underway

As described in the Carmacks PEA technical report, the Company has identified the potential to add significant additional cash flow to the Carmacks project through processing of oxide tailings to increase total copper recovery. Recovery sensitivity from the PEA shows a potential additional $180M pre-tax net present value (“NPV”) based of a 20% increase in recovery rates, which could represent an approximate 55% increase to base case NPV. The work to test the leaching response from this oxide tailings material is currently underway, with results anticipated by mid-2023 with updates to follow.
