Drilling Continues to Unlock Chanach Copper-Gold Exploration Potential
Executive Summary
- RTG Mining reports high‑grade copper and gold intercepts from its 2025 field season at the Chanach Project, including a 59.9 m @ 0.67 % Cu oxide zone and multiple >10 g/t Au hits.
- The drilling program covered 4,300 m of diamond core outside the existing resource base, targeting an IP anomaly, blind magnetic targets, and skarn zones.
- Results suggest significant upside to the current JORC‑compliant inferred resources (2.95 Mt @ 5.11 g/t Au; 17.23 Mt @ 0.37 % Cu) and indicate multiple new high‑grade targets that will require follow‑up drilling.
Key Details
- Hole DD25‑01 (Oxide Copper Target) – 59.9 m @ 0.67 % Cu from 9.6 m, including:
- 3.9 m @ 1.35 % Cu from 11.4 m
- 5.0 m @ 1.34 % Cu from 16 m
- 2.2 m @ 2.16 % Cu from 32 m
-
2.0 m @ 1.09 % Cu from 52.3 m
-
Hole DD25‑03 (Gold at Depth) – Intercepts:
- 1.0 m @ 0.90 g/t Au from 570.5 m
- 3.4 m @ 15.3 g/t Au from 754.4 m
- 1.8 m @ 7.51 g/t Au from 773.2 m
-
3.1 m @ 6.54 g/t Au from 791.7 m
-
Hole DD25‑04 (Blind Magnetic Target) – Intercepts:
- 2.0 m @ 2.24 g/t Au from 123.9 m
- 1.2 m @ 5.00 g/t Au from 193 m
-
1.0 m @ 1.25 g/t Au from 320 m
-
Hole DD25‑07 (Eastern Skarn) – 3.7 m @ 12.47 g/t Au from 174 m
-
Hole DD25‑09 (Central Skarn) – Intercepts:
- 4.5 m @ 1.76 g/t Au & 1.06 % Cu from 32.8 m, including 1.1 m @ 3.83 g/t Au & 2.4 % Cu at 36.2 m
-
7.8 m @ 11.65 g/t Au from 41 m
-
Drilling Program – 12 of 13 planned holes completed; assays for remaining holes expected in 6‑8 weeks. Total drill length to date: ~4,300 m.
-
Resource Context – Existing inferred resource: 2.95 Mt @ 5.11 g/t Au (484 k oz) and 17.23 Mt @ 0.37 % Cu (64 kt). New intercepts are outside this envelope, indicating potential for substantial resource expansion.
-
Future Work – Planned step‑out drilling on oxide copper zone, deeper gold targets, additional blind magnetic and skarn zones; further structural mapping and geophysical interpretation to define extensions.
