KODIAK ANNOUNCES FILING OF NI 43-101 TECHNICAL REPORT: INITIAL MINERAL RESOURCE ESTIMATE ON FOUR OF SEVEN MINERALIZED ZONES AT THE MPD COPPER-GOLD PROJECT

Kodiak Copper Corp. has filed an independent technical report on SEDAR+, prepared in accordance with National Instrument 43-101, Standards of Disclosure for Mineral Projects, in support of initial mineral resource estimates for four deposits on the company's 100-per-cent-owned MPD copper-gold project in Southern British Columbia. Mineral estimates on three additional mineralized zones are being developed and are anticipated in the second half of 2025 (see news release dated June 25, 2025).

Highlights:

• Sizable initial copper-gold mineral resource estimate (MRE) prepared for four of seven mineralized zones outlined to date at MPD: Gate, Ketchan, Man and Dillard;
• Indicated mineral resource: 56.4 million tonnes (t) grading 0.42 per cent copper equivalent (CuEq) for 385 million pounds (lb) of copper (Cu) and 250,000 ounces (oz) of gold (Au) (see table 1);
• Inferred mineral resource: 240.7 million t grading 0.33 per cent CuEq for 1,291 million lb Cu and 960,000 oz Au (see table 1);
• The MRE is defined using open-pit design shells to constrain the resource models and a cut-off grade of 0.2 per cent CuEq. Sensitivity cases using lower cut-off grades have significantly higher tonnages and metal contents (see table 2);
• Mineralization remains open for expansion within and beyond the MRE pit shells, in multiple directions and at depth;
• The full MRE for all seven mineralized zones at MPD is planned for completion in Q4 (fourth quarter), 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 the 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;
• The report is available on SEDAR+ and on the company's website.

Initial mineral resource estimate

The drill hole density in the central part of the Gate zone was sufficient to develop a 56.4 million t indicated resource grading 0.42 per cent CuEq. Inferred resources at the Man, Dillard, Ketchan and Gate zones total 240.7 million t with an average grade of 0.33 per cent CuEq (see table 1). The inferred resource at Gate is peripheral to the indicated resource.

Sensitivity cut-off grades

In addition to the base case cut-off grade (COG) of 0.2 per cent CuEq, a range of cut-off grades from 0.12 per cent to 0.22 per cent CuEq was applied to the resource models to evaluate the potential effect on tonnage, grade and metal content (see 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.

Qualified persons

The report was prepared by Alfonso Rodriguez, MSc, PGeo (Apex Geoscience Ltd.), James Gray, PGeo (Advantage Geoservices Ltd.), and Shane Tad Crowie, PEng (JDS Energy and Mining Inc.), each of whom are independent qualified persons as defined by National Instrument 43-101. The effective date of the report is June 25, 2025.

The MRE was prepared by Mr. Gray with contributions from Tysen Hantelmann, PEng, of JDS Energy, for cut-off grade and pit shell optimization, and Mr. Crowie for metallurgical parameters, in accordance with the 2014 Canadian Institute of Mining, Metallurgy and Petroleum Definition Standards and Canadian National Instrument 43-101. Mr. Gray, Mr. Hantelmann and Mr. Crowie are independent qualified persons as defined by NI 43-101, and have reviewed and approved the contents of this news release. Dave Skelton, PGeo (Alberta), vice-president of exploration and a qualified person as defined by NI 43-101, has approved and verified the technical information used in this news release. The historical work referenced herein is believed to be from reliable sources using industry standards at the time, based on Kodiak's review of available documentation. However, the company has not independently validated all historic work and the reader is cautioned about its accuracy.

Stock option grant

Kodiak also granted 32,000 stock options to an adviser of the company. The options are exercisable at 63 cents per share for a period of five years from the date of grant, with one-third vesting immediately and one-third every year thereafter. The options were granted pursuant to the company's shareholder-approved stock option plan, and are subject to the policies of the TSX Venture Exchange and any applicable regulatory hold periods.

About Kodiak Copper Corp.

Kodiak is focused on its 100-per-cent-owned copper porphyry projects in Canada and the United States that have been historically drilled and present known mineral discoveries with the potential to hold large-scale deposits. Kodiak Copper's most advanced asset is the 100-per-cent-owned MPD copper-gold porphyry project in the prolific Quesnel terrane in south-central British Columbia, Canada, a mining district with producing mines and excellent infrastructure. MPD exhibits all the hallmarks of a major, multicentred porphyry district with the potential to become a top-tier mine. To date, drilling has outlined seven substantial mineralized zones across the property and Kodiak is delivering an initial resource estimate for MPD in 2025. The estimate for the first four mineralized zones has already highlighted the project's scale and potential. Drill results on the remaining three zones from Kodiak's 2025 exploration program will be incorporated into the full initial resource estimate, expected by the year-end. With known mineralized zones open to expansion and multiple untested targets, Kodiak continues to systematically explore the district-scale potential of MPD to build critical mass and make the next discovery.

Kodiak's founder and chairman is Chris Taylor, who is known for his gold discovery success with Great Bear Resources. Kodiak is also part of Discovery Group, led by John Robins, one of the most successful mining entrepreneurs in Canada.
