Granite Creek Copper Ltd. Confirms New Mineralized Zone in 2024 Drilling At Carmacks Copper-Gold-Silver Project in Yukon, Canada Granite Creek Copper Ltd. announced 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, 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. The Gap Zone lies between the proposed 147 and 2000S pits and was first identified by a 2022 geophysical IP survey. 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 PEA. 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. 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). 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 C anada, 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 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. お知らせ • Oct 18

Granite Creek Copper Launches 2024 Drill Campaign At Carmacks Copper-Gold-Silver Project in Yukon, Canada Granite Creek Copper Ltd. announced that drill crews and equipment have been mobilized to commence drilling at its wholly owned Carmacks copper-gold-silver project located in central Yukon, Canada. The program will consist of approximately 1,800 meters of core drilling designed to test compelling new targets adjacent to existing high-grade, pit-constrained resources, namely the Gap, Sourtoe and Zone 4 target areas. Primary among these will be the Gap Target which lies between the 147 and 2000 S zones and may represent a fault offset of either or both zones. Modest, shallow drilling was completed by previous operators, but none to date have tested a large target identified in geophysical work by the Company which shows an Induced Polarization (IP) response nearly double that of the 147 Zone where high-grade mineralization is well defined.

Granite Creek Copper Receives Final Metallurgical Results Demonstrating 88% Oxide Copper Recovery Granite Creek Copper Ltd. announced 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. The current test results show a total recovery of 88% for oxide material is possible, an increase of 48% over the PEA base case. These results will have a significant impact on the economics for the project as the PEA identified an additional $180 M of NPV5% 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. 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. お知らせ • Oct 26
Granite Creek Copper Ltd. Receives Preliminary Metallurgical Results Demonstrating Potential for Significant Additional Copper Recovery Granite Creek Copper Ltd. announced 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. お知らせ • Oct 06

Granite Creek Copper Ltd. Reports Positive Results from its Preliminary Economic Assessment for the Carmacks Copper-Gold-Silver Project Granite Creek Copper Ltd. reported positive results from its Preliminary Economic Assessment (PEA) for the Carmacks Copper-Gold-Silver project (the Project or Carmacks Project), located in the Yukon, Canada's Minto Copper District within the traditional territories of Little Salmon/Carmacks First Nation and Selkirk First Nation. The PEA demonstrates attractive project economics with significant opportunities for additional mine life expansion, reinforcing the potential of the Minto Copper District to become a top-tier global copper district. The Company envisions developing the Carmacks Project into a low-carbon source of copper. A critical mineral, as defined by the Canadian government, copper is key to the transition to a zero-carbon economy through the electrification of transportation and other industries, and the development of renewable energy production. The 2023 PEA clearly demonstrates the viability of the Carmacks Deposit as a robust open pit sulphide and oxide copper-gold-silver project with significant potential upside from both resource expansion and secondary processing of oxide material to further improve oxide recoveries. The Project is to be powered by the Yukon's electrical grid which uses primarily renewable electricity. The PEA contemplates open pit mining using a conventional truck and shovel operation in two separate pits. Mining targets the high-grade, near surface oxide material in the 147 pit, then transitions to target sulphide material in the 1213 pit followed by final mining of the deeper oxide and sulphide material in 147. Mined material would be delivered to a crushing and grinding circuit consisting of a primary crusher, SAG mill and ball mill. Both oxide copper ore and sulphide copper ore would be processed via a simplified flow sheet consisting of well-established flotation technology producing a high-quality copper-gold-silver concentrate. Oxide and sulphide ore would be blended and sequenced to provide optimal cash flow and to minimise the environmental footprint with mined-out pits or portions of pits being reclaimed as mining commences in the next area. Both conceptual pits lie within 2km of the proposed mill site. Tailings from the flotation circuit would be filtered and water recirculated into the flotation circuit. This would improve water management and limit environmental impact, with final tailings placement on a lined dry stack tailings facility at site. A high-grade, premium copper, gold and silver concentrate would be shipped via deep seaports in Skagway, Alaska or other nearby facilities. Treatment and refining charges terms are within standard market rates. Average copper recovery during life of mine ("LOM') is calculated to be 64% with approximately 2/3 of material processed being oxide ore and 1/3 being sulphide ore. Metallurgical studies returned 93% copper recovery when processing sulphide ore, 40% copper recovery while processing oxide ore and 82% when processing a 50:50 blend. Metallurgical work highlights the opportunity for further optimization of the Project through more detailed mine sequencing or discovery of near mine sulphide or that could be blended with ore from the 147 pit. The PEA for the Project outlines an initial (pre-production) capital cost estimate of C$220 million and LOM sustaining capital costs of C$130 million, including overall closure costs of C$5 million. Initial capital costs include the construction of milling and processing facilities, lined dry stack tailings and lined waste rock facilities, on-site infrastructure of 15km of access road and facilities for water capture and treatment. Construction of a powerline (12.8 km, 138 kV) from an existing substation is placed under sustaining capital to allow for construction time of the power grid. Operating costs estimates were developed using first principles methodology, vendor quotes received in Third Quarter 2022, and productivities being derived from benchmarking and industry best practices. Over the LOM, the average operating cost for the Project is estimated at C$3.16/t mined and C$18.30/t processed. Tailings costs are included in processing costs. The average cash operating costs over the LOM is US$1.76/lb CuEq and the average AISC is US$2.57 /lb CuEq. The PEA indicates that the potential economic returns from the Project justify advancing to a feasibility study. The Project generates cumulative cash flow of C$371.2 million on an after-tax basis and C$505.8 million pre-tax at a base case of $3.75/lb Cu based on an average mill throughput of 7,000 t/day over the 9-year life of mine. The PEA is significantly influenced by copper price assumptions. Using the Case 1 metal price scenario consists of near current prices of US$4.25/lb Cu, US$2000/oz Au and US$25/oz silver, the Project generates an after-tax Net Present Value ("NPV") using an 5% discount rate of $328 million and an after-tax IRR of 38% with a payback period of 1.5 years from the commencement of production. (Table 3), Outlined below in Table 4 is a detailed sensitivity analysis across gold and copper prices with silver kept at $22/ounce. Table 5 below highlights additional sensitivities to foreign exchange, recovery, CAPEX and OPEX. The third conceptual pit, 2000S as identified in the Mineral Resource Estimate ("MRE), could be brought into the mine plan if sufficient additional resources were defined by drilling to offset pre-stripping costs. Electrification of the mining fleet. Significant cost saving and reduction in greenhouse gas production may be possible through the sourcing of electric vs. diesel haul trucks for the Project. The PEA envisions using a contract mining fleet for the Project and preference will be given to suppliers that can provide either fully electric or hybrid equipment. Further discovery. Exploration conducted in 2022 consisting of geophysics, trenching and soil sampling identified four areas proximal to the proposed mine plan that if successfully drilled could enable longer mine life beyond nine years or provide additional sulphide mill feed earlier in the mine's life. Four targets on the Property require evaluation, all located within 1km of the current deposits. Two of the targets are located beneath the current resource and there is higher geological certainty that these may contain appreciable copper mineralization. Zone 1213 shallow: Downward continuation of Zone 12 and 13. Estimated dimensions are 360m long, 15 - 40m wide, starting at approximately 65m below the current drilling. Zone 12 deep: Downward continuation of Zone 12. Estimated from geophysics to be continuing for an additional 170m below current resource modelling. Approximated to be 580m long and 15-40m wide. Gap Zone target: Geophysical anomaly that fits with current geological understanding of the fault offset between 147 and 2000S Zone. お知らせ • Jan 11
Granite Creek Copper Ltd. Reports on Metallurgical Results in Support of an Updated PEA on the Carmacks Copper-Gold Project in Yukon, Canada Granite Creek Copper Ltd. reported positive metallurgical results in support of the upcoming Preliminary Economic Assessment for the Carmacks copper-gold-silver 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. 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.
