KODIAK FILES NI 43-101 TECHNICAL REPORT: INITIAL MINERAL RESOURCE ESTIMATE 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 the initial mineral resource estimate on the company's 100-per-cent-owned MPD copper-gold project in Southern British Columbia.

Highlights:

• Large, open-pit copper-gold initial mineral resource estimate (MRE), which shows the scale and potential of MPD and lays the foundation for future resource growth and development;
• The initial MRE comprises seven deposits: West, Adit, South, Gate, Ketchan, Man and Dillard;
• Total indicated mineral resource: 82.9 million tonnes grading 0.39 per cent copper equivalent for 519 million pounds of copper and 390,000 ounces of gold (Table 1);
• Total inferred mineral resource: 356.3 million tonnes grading 0.32 per cent CuEq for 1,889 million pounds of Cu and 1.28 million ounces of Au (Table 1);
• The MRE is defined using a cut-off grade of 0.2 per cent CuEq; sensitivity cases using lower cut-of grades typical of producing mines in the area have significantly higher tonnages and metal contents (Table 2);
• All deposits remain open for expansion within and beyond the MRE pit shells, most in multiple directions and at depth; Kodiak's work in 2026 will be focused on resource growth; in addition, Kodiak intends to test some of the numerous underexplored targets on the MPD property, which present opportunities to discover new mineralized zones;
• The report is available on SEDAR+ and on the company's website.

Initial mineral resource estimate

The drill hole density in the South zone, the West zone and the central part of the Gate zone was sufficient to develop a 82.9-million-tonne indicated resource grading 0.39 per cent CuEq. Inferred resources at the Man, Dillard, Ketchan, Gate, Adit, South and West zones total 356.3 million tonnes with an average grade of 0.32 per cent CuEq (see Table 1). The effective date for the MRE reported herein is Dec. 9, 2025.

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 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.

Next steps

Kodiak is actively advancing the MPD project through the following key work streams and coming catalysts in 2026:

• Metallurgical test results - Q1;
• Soil results and drill targets -- Q1;
• Resource expansion drilling -- Q2 onward;
• Exploration drilling and testing new targets -- Q2 onward;
• Geophysical programs -- Q2 onward;
• Resource update -- Q1 2027;
• Continuing structural studies;
• Continued environmental baseline studies;
• Continuing engagement with indigenous rightsholders and local stakeholders.

About Kodiak Copper Corp.

Kodiak is focused on advancing its copper porphyry projects in Canada and the United States, which host 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, an established mining region with producing mines and excellent infrastructure. MPD exhibits all the hallmarks of a large, multicentred porphyry district with the potential for future economic development. The initial mineral resource estimate published in 2025 outlines seven substantial deposits and underscores the scale and potential of the project. All known deposits remain open to expansion, and numerous targets across the property have yet to be tested. Kodiak continues to systematically explore MPD's district-scale potential with the goal of delivering new discoveries and building further critical mass toward being the region's next mine.

Chris Taylor, Kodiak's founder and chairman, is well 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.
