Kodiak Reports Initial Mineral Resource Estimate on Four of Seven Mineralized Zones at the MPD Copper-Gold Project

Rhea-AI Summary

Kodiak Copper (OTCQB: KDKCF) has announced its initial Mineral Resource Estimate (MRE) for four of seven mineralized zones at its 100%-owned MPD copper-gold project in British Columbia. The estimate reveals an Indicated Mineral Resource of 56.4 million tonnes grading 0.42% copper equivalent, containing 385 million pounds of copper and 0.25 million ounces of gold. The Inferred Resource stands at 240.7 million tonnes grading 0.33% copper equivalent, containing 1,291 million pounds of copper and 0.96 million ounces of gold.

The MRE covers the Gate, Ketchan, Man, and Dillard zones, with mineralization remaining open for expansion. The company plans to complete the full MRE in Q4 2025 by adding three additional zones (West, Adit, and South). The estimate uses a cut-off grade of 0.2% copper equivalent, with sensitivity analysis showing significant potential for increased tonnage at lower cut-off grades.

Positive

• Initial MRE shows substantial resource with 385 Mlb copper and 0.25 Moz gold in Indicated category
• Additional 1,291 Mlb copper and 0.96 Moz gold in Inferred category
• Mineralization remains open for expansion in multiple directions
• Three additional zones pending inclusion could significantly increase total resource
• Sensitivity analysis shows potential for larger resource at lower cut-off grades

Negative

• Current MRE only covers 4 out of 7 mineralized zones
• Economic viability not yet demonstrated as resources are not reserves
• Additional drilling and studies required for full project evaluation

Vancouver, British Columbia--(Newsfile Corp. - June 25, 2025) - Kodiak Copper Corp. (TSXV: KDK) (OTCQB: KDKCF) (FSE: 5DD1) (the "Company" or "Kodiak") today reports the first part of its initial Mineral Resource estimate at the Company's 100%-owned MPD copper-gold project in southern British Columbia, which comprises four of seven mineralized zones.

Highlights

• Sizable copper- gold initial Mineral Resource estimate ("MRE") delineated for four of seven mineralized zones outlined to date at MPD: Gate, Ketchan, Man and Dillard. Figure 1

• Indicated Mineral Resource: 56.4 million tonnes (Mt) grading 0.42% copper equivalent (CuEq) for 385 million pounds (Mlb) of copper (Cu) and 0.25 million ounces (Moz) of gold (Au). Table 1

• Inferred Mineral Resource: 240.7 million tonnes (Mt) grading 0.33% copper equivalent (CuEq) for 1,291 million pounds (Mlb) of copper (Cu) and 0.96 million ounces (Moz) of gold (Au). Table 1

• The MRE is defined using open pit design shells to constrain the Resource models and a cut-off grade of 0.2% CuEq. Sensitivity cases using lower cut-of grades have significantly higher tonnages and metal contents. Table 2

• Mineralization remains open for expansion within and beyond the MRE pit shells, in multiple directions and at depth.

• The full MRE for MPD is planned for completion in Q4 with the addition of three further mineralized zones (West, Adit and South), where confirmation and infill drilling is currently under way as part of the Company's 2025 exploration program (see news release June 18, 2025).

• The higher-grade, near surface mineralization identified at the West, Adit and South zones has the potential to make an important contribution to the full MRE. Figure 1

Join President & CEO Claudia Tornquist and Chairman Chris Taylor as they discuss the
Initial Mineral Resource Estimate for Kodiak Copper's MPD Project

Claudia Tornquist, President and CEO of Kodiak, said, "The initial Resource estimate for MPD is an important strategic milestone for Kodiak and marks the culmination of six years of systematic exploration and district consolidation. The estimate released today is for only four of the seven mineralized zones that will form the full Mineral Resource estimate for MPD but it already shows the considerable scale and potential of the project. We are currently drilling the remaining three mineralized zones and plan to incorporate the results into the full Mineral Resource estimate for MPD by the end of this year. I am looking forward to the next stage in MPD's development as we progress towards economic evaluation."

Chris Taylor, Chairman of Kodiak, said, "I've had the vision right from the start that MPD's rich mineral endowment holds the potential for a major mine in British Columbia and our initial Resource estimate clearly demonstrates this. We expect to grow this Resource estimate substantially with the inclusion of the remaining zones later this year. It is also worth noting that our sensitivity analysis shows a significant increase in tonnage and metal content when using a lower cut-off grade of 0.12% copper equivalent, which is comparable to mines in the area. I consider this initial Resource estimate a starting point for future growth, as most of our zones remain open to extension, and our work to date has identified more than 20 additional copper and gold occurrences and targets."

Initial Mineral Resource Estimate

The drill hole density in the central part of the Gate Zone was sufficient to develop a 56.4 Mt Indicated Resource grading 0.42% CuEq. Inferred Resources at the Man, Dillard, Ketchan and Gate zones total 240.7 Mt with an average grade of 0.33% CuEq (see Table 1). The Inferred Resource at Gate is peripheral to the Indicated Resource. The effective date for the MRE reported herein is June 25, 2025. Figure 2 shows the MRE pit shells that support the Reasonable Prospects of Eventual Economic Extraction (RPEEE).

Notes: 1. The Mineral Resources were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum(CIM), Definition Standards for Mineral Resources and Reserves, as prepared by the CIM Standing Committee and adopted by CIM Council.

2. A cut-off grade of 0.2% CuEq was applied to the MRE models within the pit shells.

3. Pit shell optimization used average recoveries derived from metallurgical test work of Cu 82%, Au 60% and Ag 54%, exchange rate of 1.35 CAD:USD, mining cost of C$2.3/t, process cost of C$8.5/t, and pit slope of 45 degrees.

4. Copper equivalence (CuEq) and constraining pit shells assume metal prices (US$) of: $4.2/lb copper, $2,600/oz gold, $30/oz silver.

5. The copper equivalency equation used is: CuEq(%) = Cu(%) + Au(g/t) x 0.6606 + Ag(g/t) x 0.0069

6. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. There is no certainty that all or any part of the mineral resources will be converted into mineral reserves in the future. The MRE may be materially affected by considerations including, but not limited to, permitting, legal, sociopolitical, environmental issues, market conditions or other factors.

7. All figures are rounded to reflect the relative accuracy of the estimate. Totals may not sum due to rounding as required by reporting guidelines.

Sensitivity Cut-off Grades

In addition to the base case cut-off grade ("COG") of 0.2% CuEq a range of cut-off grades from 0.12% to 0.22% CuEq were applied to the Resource models to evaluate the potential effect on tonnage, grade and metal content (Table 2). Lower cut-off grade sensitivity cases demonstrate a notable increase in tonnage and in-situ metal, with a decrease in average grades. The values in the COG sensitivity cases are for comparison purposes only and should not be considered Mineral Resources.

Estimation Methods

The Resource estimate was completed by James N. Gray, P.Geo. of Advantage Geoservices Ltd., an Independent Qualified Person as defined by National Instrument 43-101 Standards of Disclosure for Mineral Projects (NI 43-101) in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Standards on Mineral Resources and Mineral Reserves, adopted by CIM Council, as amended. Estimation methods are summarized below. The Gate and Man Resource estimates are controlled by an alteration model based on three-dimensional interpretation of drill results. Estimation control at Dillard and Ketchan is based on models of lithology. A total of 216 core drill holes, completed by Kodiak and previous operators through 2024, have been used for grade estimation at MPD-N; 70 holes at Gate, 47 at Man, 35 at Dillard and 64 at Ketchan. Of the 216 core holes drilled, 89 were completed under the supervision of Kodiak. Minor high-grade capping was applied to assay values to appropriately control the impact of outliers to copper, gold, and silver distributions, prior to compositing to a length of three metres. Grades at Gate were estimated by ordinary kriging; Man, Dillard and Ketchan grades were estimated by inverse distance weighting. Block size was 10 x 10 x 10 m for all Mineral Resources. Average rock densities were applied based on models of lithology. A total of 13,419 density measurements have been made on core samples in MPD-N. Bulk density averages 2.65 tonnes/m³ at Gate, 2.51 tonnes/m³ at Man, 2.57 tonnes/m³ at Dillard and 2.64 tonnes/m³ at Ketchan.

Block models were classified based on a calculated drill spacing. Blocks were assigned as an Inferred Mineral Resource where drilled at up to a 150 metre spacing. At Gate, where more drill information has allowed a higher degree of confidence in the geologic model, blocks at a drill spacing of up to 70 m have been classified as an Indicated Mineral Resource.

Reasonable prospects of eventual economic extraction (RPEEE) were established by JDS Energy & Mining Inc ("JDS") to constrain the MRE. To consider the RPEEE, JDS produced Lerchs-Grossmann optimized pit shells at each project area using the following parameters: Cu US$4.2/lb, Au US$2,600/oz, Ag US$30/oz, an exchange rate of 1.35 CAD:USD, average recoveries of: 82% Cu, 60% Au and 54% Ag, slope of 45°, mining cost of C$2.30/t and an average process cost of C$8.50/t (including G&A). Recovery assumptions were determined by JDS from the initial metallurgical testwork conducted earlier this year. All material included in the MRE is contained within the optimized pit shells.

Quality Assurance and Quality Control procedures employed by Kodiak for the laboratory analysis of drill core included the inclusion of certified standards, blanks and duplicates. All Kodiak samples were sent to ALS Canada Ltd for analysis where the analytical procedures meet the requirements of International Standards ISO/IEC 17025:2005 and ISO 9001:2015. The historic results included in the Mineral Resources were reviewed and are believed to be from reliable sources using industry standards at the time, however the company has not independently verified, or cannot guarantee, the accuracy of historical information. The historical results will be summarized in the accompanying NI 43-101 technical report.
