Puma Exploration launches Kinross Gold drilling at Williams Brook

Rimouski, Québec--(Newsfile Corp. - August 12, 2026) - Puma Exploration Inc. (TSXV: PUMA) (OTCQB: PUMXF) ("Puma" or the "Company") is pleased to announce that Kinross Gold Corp. ("Kinross") has begun another round of drilling at the Williams Brook Gold Project under its Option Agreement. The initial 2,000-metre drilling program was launched at the Jaguar Gold Zone ("JGZ") on July 26, 2026. To date, it includes seven (7) holes (ranging from 200 to 500 metres) that will follow up on results from Kinross' Winter 2026 drilling program. It will target the core of the Jaguar Gold Zone and step-out drill-test other geophysical anomalies about 500 metres away in the area (Figure 1).

The Jaguar Gold Zone, located about 5 km northeast of the Lynx Gold Zone ("LGZ"), has seen limited historical work. An IP survey was conducted in the area in 2007/2008, and a previous operator drilled four holes (WB08-03, 04, 06, 08). Hole WB-08-03 intersected significant gold mineralization, with 2.10 g/t Au over 9.00 m within a broader gold envelope grading 0.52 g/t Au over 55.00 m (see September 4, 2025 News Release ). Puma later advanced the target through prospecting, trenching and sampling, identifying an approximately 80 by 50 metres gold-enriched zone, with selected grab samples returning up to 34.70 g/t Au* ( see December 13, 2022 News Release ). *The reader is cautioned that grab samples are selective by nature and may not represent the true metal content of the mineralized zone.

In early 2026, Kinross launched a five (5)-hole drilling campaign at Jaguar to follow up on historical and surface results, and define the stratigraphic framework and structural controls at the JGZ. The 1,360-metre program tested the Jaguar system from different drilling orientations and targeted extensions of known mineralization, as well as new structural and geophysical indicators. 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 that coincides with a large geophysical (Induced Polarization "IP") anomaly identified at surface, suggesting that the gold-bearing system here may be associated with a broader chargeability response (see May 21, 2026 News Release ).

Kinross' current 2026 drilling is designed to target the lateral and down-plunge extensions of mineralization intersected during the Winter 2026 program, further constrain the geometry and extent of the rhyolite unit, and continue to evaluate the structural significance and displacement associated with faults. The potential for additional mineralized zones along other IP anomalies in the area (within 300-500 metres) and at depth will also be tested by drilling to the north and southeast. These zones identified in the 2007/2008 IP survey correspond to prospective bedrock exposures that were investigated through test pitting during this summer's field program.

MORE ABOUT THE SUMMER 2026 EXPLORATION PROGRAM AT WILLIAMS BROOK

Kinross' Summer 2026 exploration program at the Williams Brook Gold Project was launched in May and included prospecting, geological mapping, trenching (Test Pits), soil surveys, and a magnetic geophysical survey.

The fieldwork was prioritized by the need to renew the claims and by the prospectivity of the areas. The exploration focus became increasingly concentrated on the highest-quality targets, with the Jaguar Gold Zone emerging as the target warranting follow-up drilling.

The May to July 2026 program included:

Regional Prospecting and Geological Mapping Three (3) field crews systematically explored the entire property from May through July and collected grab samples.

Soils Geochemistry Surveys Two (2) grids of soil geochemistry were completed:

Jonpol Soil Survey : 669 total samples (including 620 original soils, 15 duplicates, 17 blanks and 17 CRM tills).

9218 Soil Survey : 742 total samples (including 685 original samples, 20 duplicates, 18 blanks and 19 CRM tills).

Jaguar Pits Trenching Program 32 test pit trenches were excavated in the Jaguar Gold Zone (Figure 3).

Drone Magnetic Survey A drone magnetic survey covering 2,920.9 hectares was completed. The area surveyed ties together two (2) previous surveys, with the magnetic data now covering an area extending from the Lynx Gold Zone to the Lion Gold Zone.

The exploration program to date has successfully refined several high-priority drill targets and demonstrated a large, multi-kilometre hydrothermal alteration system. Results from the program are pending and will be announced when received.

The three (3) field crews will continue to explore the Williams Brook Project until September. Additional drilling may be added according to the results of the current program and the budget.
