KODIAK INCREASES DRILL PROGRAM TO 16,500 METRES AND ADDS SECOND DRILL RIG

Kodiak Copper Corp. today provided an update on its fully financed 2026 exploration program at its 100-per-cent-owned MPD copper-gold porphyry project in Southern British Columbia. Work is progressing well and the drill program has been increased from 6,500 metres to 16,500 metres with the addition of a second drill rig.

Highlights

• The program upsize accelerates work to grow the initial mineral resource estimate (MRE). All seven deposits in the MRE are open to expansion, most in multiple directions, and drilling is being considered for all of the deposits in 2026.
• Kodiak's 2026 exploration program commenced at the beginning of May and is expected to continue through late autumn.
• Drilling was initiated on the Ketchan deposit where 2,546 metres in 14 holes have been drilled to date. Ketchan is currently defined over approximately 1.4 kilometres and has significant expansion potential. The associated soil anomaly extends to over two kilometres and multiple mineralized historic drill holes beyond the deposit are not included in the MRE due to insufficient drill hole density (see news release April 9, 2026).
• A second drill rig has been mobilized to the southern part of the property where a 3-D induced polarization/audio- magnetotelluric survey on the West, Adit and South deposits has just been completed in anticipation of drilling.
• In addition to resource expansion drilling, it is anticipated that several of the 36 prospective exploration targets identified to date will be advanced and drill tested this year.
• Samples are in the laboratory and first drill results are expected by August, with further results throughout the remainder of the year. The results will be incorporated into an updated MRE which is planned for Q1 2027.

Claudia Tornquist, president and chief executive officer of Kodiak, said: "The 2026 exploration program at MPD is progressing very well, and the addition of a second drill will fast-track our progress as we advance resource growth opportunities across the project and test priority targets. We continue to see considerable scope to expand our maiden resource and are excited by the prospect of new discoveries across our portfolio of targets. With the first assay results expected soon, our shareholders can look forward to strong news flow and many exploration results throughout the remainder of the year, leading to an updated resource estimate in 2027 that will reflect the results of the expanded drilling program."

Dave Skelton, PGeo, vice-president, exploration, and a qualified person as defined by National Instrument 43-101, has approved and verified the technical information in this news release.

About Kodiak Copper Corp.

Kodiak is focused on advancing its 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 existing 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. The company also holds the Mohave copper-molybdenum-silver porphyry project in Arizona, United States, near the world-class Bagdad mine.

Kodiak's founder and chairman, Chris Taylor, 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.
