Corporate Update - QCM Property Exploration Update

CALGARY, AB / ACCESS Newswire / August 13, 2026 / Kestrel Gold Inc. ("Kestrel" or the "Corporation") (TSXV:KGC) is pleased to provide shareholders and the investment community with an exploration update on its 100%-owned QCM Property, located in the Manson-Germanson District of British Columbia, where Centerra Gold Inc. ("Centerra") (TSX:CG)(NYSE:CGAU) is advancing an option earn-in program with CGSI as project operator. This release summarizes highlights from the 2026 surface exploration program completed in the second quarter of 2026, and from Centerra's 2025 diamond drill program, completed in the fourth quarter of 2025.

Following the 2025 drill program, Centerra conducted a regional soil sampling, prospecting, and structural mapping program at QCM during June 2026, focused on the historical Flagstaff showing and surrounding target areas. Field crews mobilized to site on June 9, 2026, with geological and geochemical activities conducted from June 13 to June 25, 2026.

• 784 of 1,011 planned Priority 1 soil samples were collected, completing the Priority 1 sampling program; remaining planned sites could not be sampled due to unfavourable ground conditions (glaciofluvial cover, insufficient fine material, or wetland terrain)

• 96 of 364 planned Priority 2 soil samples (26%) were collected, with the program continuing

• 100 rock samples were collected across the property

• 59 outcrop exposures were documented and 40 high-confidence structural measurements were recorded

Mapping at the Flagstaff showing identified intense Fe-carbonate and moderate mariposite alteration within approximately 50 m of the historic drill collars, together with three distinct quartz vein orientations. Approximately 500 m southeast of Flagstaff, follow-up work at historical anomalies (up to 0.74 g/t Au in soil and 0.15 g/t Au in rock) identified similar alteration and vein characteristics, including localized zones of 5-7% pyritohedral pyrite, indicating potential for the Flagstaff-style mineralized footprint to extend along strike.

Centerra completed 9,110.5 metres of diamond drilling in 36 holes between May 25 and October 31, 2025, comprising 6,305.5 metres at the Main Zone and 2,805.0 metres at the 14 Vein target, located approximately 7 km apart on the property. Drill results were announced previously in news releases dated October 10, 2025 and February 10, 2025. Please see these news releases for full details.

Main Zone

Drilling confirmed and extended historically known gold mineralization, defining a zone of continuous mineralization approximately 500 m long by 180 m wide by 180 m deep that consistently returns average grades of 0.5 to 0.8 g/t Au. Results indicate the zone remains open to the northwest. Selected highlights include:

• QCM-25-006: 137.00 m @ 0.522 g/t Au from 136.00 m

• QCM-25-005: 48.00 m @ 0.823 g/t Au from 87.00 m

• QCM-25-033: 72.00 m @ 0.578 g/t Au from 152.00 m

• QCM-25-036: 93.94 m @ 0.501 g/t Au from 18.06 m

• QCM-25-035: 72.00 m @ 0.591 g/t Au from 319.00 m

• QCM-25-002: 19.00 m @ 0.798 g/t Au from 3.00 m, including zone up to 7.50 g/t Au

Figure 3: Drill core from QCM-25-006 (193.81-197.40 m), Main Zone - quartz-sericite-ankerite altered greywacke; the 195-196 m interval returned 2.2 g/t Au.

14 Vein

2025 drilling delineated a mineralized zone approximately 200 m by 20 m, trending northwest-southeast and dipping gently to the southwest, with typical grades of 0.4 to 0.6 g/t Au. Drilling has now defined both the northwest and southwest limits of the vein. Selected highlights include:

• QCM-25-018: 25.00 m @ 0.632 g/t Au from 91.00 m

• QCM-25-019: 33.84 m @ 0.412 g/t Au from 49.16 m

• QCM-25-025: 22.35 m @ 0.661 g/t Au from 207.00 m

A step-out hole 100 m north of the 14 Vein, QCM-25-022, returned 11.00 m @ 0.975 g/t Au from 25.00 m (including 7.00 m @ 1.347 g/t Au), identifying a new target warranting follow-up as a potential parallel mineralized structure. A 500 m step-out hole to the northwest, QCM-25-030, intersected visible gold in quartz veining at 104 m and helped define the broader target area.
