Puma Confirms Broad Gold System at Jaguar; Kinross Launches 2026 Summer Program at Williams Brook

Rimouski, Québec--(Newsfile Corp. - May 21, 2026) - Puma Exploration Inc. (TSXV: PUMA) (OTCQB: PUMXF) ("Puma" or the "Company") is pleased to announce results from Kinross Gold Corp's ("Kinross") 1,870-metre Winter 2026 diamond drilling campaign at the Williams Brook Gold Project in Northern New Brunswick, which was completed and funded under its option agreement with Puma Exploration. At the Jaguar Gold Zone ("JGZ"), hole WB26-195 intersected a wide mineralized envelope grading 0.45 g/t Au over 56.50 m , including a higher-grade interval of 1.03 g/t Au over 16.0 m . Although only 5 shallow holes were drilled in the area, the consistent downhole mineralization, along with drilling by a previous operator in 2008, highlights the area's potential.

Kinross is targeting Jaguar for follow-up drilling this summer. At the Lion Gold Zone ("LIGZ"), the presence of high-grade gold mineralization (16 g/t Au over 0.50 m) in the first drilling ever conducted in the area confirms that the zone merits further investigation. Marcel Robillard, Puma's President and CEO, stated, " The broad mineralized interval in hole WB26-195 shows that what was sampled at Jaguar and what previous operators drilled is not a narrow, high-grade occurrence, but a wider gold-bearing system with strong potassic alteration and pyrite mineralization.

Jaguar has been added as a high-priority target within the Williams Brook Gold System. Kinross' Option agreement commitments have been instrumental in advancing the Project, and with another $13M+ in potential work expected over the next 4 years, we are confident we'll unlock Williams Brook's full potential ." Kinross has already launched its 2026 Summer Exploration Program at Williams Brook, with three (3) field crews on site and deployed until the end of September. Planned initial work includes a soils survey, a geophysical drone magnetic survey, and general prospecting and trenching.

A follow-up drilling program at Jaguar is expected this summer. O
