Kodiak Commences Additional Metallurgical Testing Focused on Flowsheet Development & Optimization

The testwork program will focus on flowsheet development and optimization and build on the test results received earlier this year (see news release here). It will include samples from all seven deposits that comprise the Mineral Resource Estimate at MPD: Gate, Ketchan, Man, Dillard, West, Adit and South (see Figure 1). Sample selection was designed to be representative of the mineralization, grade, lithology, and spatial variability across each deposit. Four composite samples representing the Southern Area (South, West and Adit), Northern Area (Man and Dillard), Ketchan and Gate will be tested. Testing will include mineralogy, comminution, gravity testwork for gold, flotation rougher and cleaner optimization, locked cycle testing and concentrate quality assessment. The results from the program are expected in Q1 2027.

Claudia Tornquist, President and CEO of Kodiak, said, "As we continue to grow the mineral resource at MPD through exploration, we are also advancing our metallurgical testwork to further de-risk the project and strengthen the foundation for future economic studies. Our metallurgical results to date are very encouraging, and this next phase of work is designed to expand on those positive findings. The program will focus on optimizing metal recoveries, particularly for gold, and produce valuable information on rock properties and hardness. Together with our ongoing exploration program and planned resource update in early 2027, this work represents another important step in unlocking the value of MPD for our shareholders."

Kodiak has engaged Fuse Advisors Inc., Part of SLR ("Fuse") to design and manage this metallurgical testwork program, with technical guidance from Kodiak advisor Mike Westendorf. Fuse is a mining consultancy with extensive experience across a wide range of deposit types and metals, including many porphyry copper projects in British Columbia. The laboratory work will be conducted in Parksville at Blue Coast Research Ltd ("Blue Coast") under the supervision of Fuse Metallurgist Renee Goold, P.Eng, an independent Qualified Person as defined by National Instrument 43-101. Blue Coast is a leading provider of metallurgical testing services for the global mining industry.

About Kodiak Copper Corp.

Kodiak is focused on advancing the 100% 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, multi-centered 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. The Company also holds the Mohave copper-molybdenum-silver porphyry project in Arizona, USA, near the world-class Bagdad mine.

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