Doubleview Gold Corp Announces Important High-Grade Copper and Gold Intercepts at Hat Polymetallic Deposit in Northwestern British Columbia

Executive Summary

• Doubleview Gold reports high‑grade copper, gold and cobalt intercepts from drill holes H090, H091 and H092 at the Hat Polymetallic Deposit, including a standout 1.2 m interval with 5.26% CuEq, 6.43 g/t Au, 7.16 g/t Ag and 230 g/t Co.
• Total drilling to date in the 2025 season: 12 holes, 8,506 m completed; results will be incorporated into an upcoming Mineral Resource Estimate (MRE) and Preliminary Economic Assessment (PEA).
• The new intercepts extend the mineralized envelope of the East Lisle Zone and suggest proximity to a potential porphyry feeder zone, enhancing the project's resource potential for strategic metals.

Key Details

• Drilling Summary: 12 drill holes, 8,506 m (27,906 ft) completed as of 11 Sep 2025; program ongoing.
• Hole H090:
• 241.8 m interval @ 0.15% CuEq (incl. 68 m @ 0.30% CuEq and 16.6 m @ 0.76% CuEq).
• Hole H091:
• 31 m @ 0.15% CuEq (18‑49 m).
• 78 m @ 0.28% CuEq (153‑231 m).
• Notable outlier: 1.2 m @ 5.26% CuEq, 6.43 g/t Au, 7.16 g/t Ag, 230 g/t Co (154.8‑156 m).
• Hole H092:
• Multiple high‑grade intervals, e.g., 24 m @ 0.69% CuEq (51‑75 m), 9 m @ 1.22% CuEq (54‑63 m), and deep sections up to 411.5 m @ 0.62% CuEq (305.5‑717 m).
• Assay Parameters Used for CuEq Calculation: Au $1,900/oz, Ag $24/oz, Cu $4/lb, Co $22/lb; recoveries – Au 89%, Ag 68%, Cu 84%, Co 78%.
• Geographic Data (UTM):
• H090 – East 347,703 m, North 6,454,749 m, Elev 1,025 m, Azimuth ‑65.12°, Dip 90°, Max depth 501 m.
• H091 – Same coordinates, Azimuth ‑88.39°, Dip 0°, Max depth 441 m.
• H092 – East 347,963 m, North 6,453,927 m, Elev 966 m, Azimuth ‑61.83°, Dip 120°, Max depth 741 m.
• Interpretation: Intercepts indicate a robust mineralization profile with consistent Cu, Au, Co and Sc presence; suggest extension of the East Lisle Zone and possible feeder zone to the Main Lisle Zone.
• Future Work: Additional assay results pending; data will feed into the next MRE and PEA.
