First Drill Hole Confirms High-Grade Copper Skarn Mineralization at the Birch Project

Executive Summary

• Initial results from the 2025 drill program at Birch reveal a 21.2 m interval averaging 0.30 % Cu (≈0.41 % CuEq), with higher‑grade sub‑intervals up to 3.5 % CuEq, indicating a sizable copper‑gold skarn system.
• Surface sampling 2 km south of the drill pad returned up to 16 g/t Au, 1,825 g/t Ag and 0.43 % Cu, supporting the presence of a broader hydrothermal footprint and a potential porphyry source.
• The program completed 1,685 m of HQ core in six holes; additional high‑grade zones are expected from upcoming holes spaced along a 1,400‑m skarn trend.

Key Details

• Drill Hole BR25‑001 (138.8–160 m):
• 21.2 m @ 0.30 % Cu (0.41 % CuEq)
• 0.6 m @ 2.50 % Cu, 0.55 g/t Au, 18.5 g/t Ag → 3.20 % CuEq

• 1.0 m @ 2.70 % Cu, 0.55 g/t Au, 24.1 g/t Ag → 3.45 % CuEq

• Additional Intercepts in BR25‑001:

• 10 m @ 0.39 % Cu, 0.10 g/t Au, 5.76 g/t Ag → 0.53 % CuEq (138.8–160 m)
• 0.9 m @ 1.50 g/t Au, 0.25 g/t Ag → 1.43 % CuEq (283.0–283.9 m)

• 0.6 m @ 0.45 % Cu, 0.45 g/t Au, 5.20 g/t Ag → 0.93 % CuEq (285.4–286.0 m)

• Geological Context:

• Intersections occur in stacked skarn horizons within schist adjacent to intrusive contacts; mineralization shows strong alteration and sulfide enrichment.

• A porphyritic intrusion at ~311 m hosts minor disseminated sulphides with anomalous Cu (350–575 ppm), suggesting a possible sub‑cropping dyke system linked to the southern anomaly.

• Prospecting Results (2 km south of drill pad):

• Highest assay: 16 g/t Au, 1,825 g/t Ag, 0.43 % Cu in quartz‑vein float.

• Other notable samples include 9.3 g/t Au with 1,115 g/t Ag and 0.20 % Cu; 7.73 g/t Au with 1,825 g/t Ag and 0.43 % Cu.

• Sample Summary (43 rocks collected):

• 13 samples returned anomalous values for one or more of Au, Ag, Cu, Mo, Pb, W, Zn.

• High‑grade silver–lead occurrences correlate with sulfosalt‑rich veins; molybdenum enrichment aligns with a potential porphyry source.

• Program Scope:

• Total core: 1,685 m HQ across six holes on four pads.

• Planned total of six holes; remaining holes (including Holes 3 & 4) are spaced ~750 m apart along the 1,400‑m skarn trend.

• QA/QC: Core split, half sent to ALS Minerals; control samples ≈10 % of total; all data meet acceptable accuracy/precision thresholds.

“We are seeing clear evidence of a copper‑gold skarn system, with high‑grade zones and strong alteration along intrusive contacts… we are particularly eager to see what emerges from Holes 3 and 4…” – Rory Quinn, President & CEO.
