Drilling Expands Near-Surface Copper-Gold Mineralization at the Birch Project

Executive Summary

• Drill holes BR25‑002 and BR25‑004 confirm a ~500 m lateral extension of skarn mineralization at the Birch project, with near‑surface high‑grade copper intervals.
• Hole BR25‑002 returned 10.1 m @ 0.21 % Cu (0.30 % CuEq) from 58.6 m depth and a higher‑grade 1.8 m @ 1.12 % Cu (1.51 % CuEq) at 124.7–126.5 m.
• Hole BR25‑004 intersected 16.0 m @ 0.20 % Cu (0.28 % CuEq), including a 1.0 m @ 0.89 % Cu (1.13 % CuEq) interval, located ~500 m east of earlier holes, demonstrating lateral continuity.

Key Details

• Program Scope: 1,685 m HQ diamond core across six holes on four pads.
• Assay Highlights – Hole BR25‑002
• 10.1 m @ 0.21 % Cu (0.30 % CuEq) from 58.6–68.6 m.
• 1.8 m @ 1.12 % Cu (1.51 % CuEq) from 124.7–126.5 m.
• Assay Highlights – Hole BR25‑004
• 16.0 m @ 0.20 % Cu (0.28 % CuEq) from 97.0–113.0 m.
• 1.0 m @ 0.89 % Cu (1.13 % CuEq) from 102.0–103.0 m (high‑grade interval).
• Additional Intercepts: Multiple shorter intervals with copper‑gold‑silver mineralization across both holes (see Table 1 for full assay list).
• Geology: Copper and gold‑bearing skarn horizons encountered at shallower depths in BR25‑002/004 versus earlier hole BR25‑001; lateral continuity of marble/skarn units confirmed.
• True Widths: Not yet determined; estimated near true thickness based on current interpretation.
• CuEq Calculation Formula: Cu % + (Au g/t × 0.95) + (Ag g/t × 0.0095), using metal prices of $4.00/lb Cu, $3,000/oz Au, $40/oz Ag; recovery factors 92 % Cu, 80 % Au, 60 % Ag.
• QA/QC: 10 % control samples, certified standards, blanks and duplicates; all data met acceptable accuracy/precision thresholds.
• Laboratory: ALS Minerals (Whitehorse sample prep; North Vancouver analysis).
• Qualified Person: Helena Kuikka, P.Geo., VP Exploration, Yukon Metals (NI 43‑101).

Notable Quotes

“These results show that the mineralized skarn horizons are both persistent and occurring closer to surface, with solid copper grades across multiple intervals. Confirming continuity between widely spaced holes strengthens our understanding of the system as we await further assays.” – Rory Quinn, President & CEO
