Troilus Drills 157.5 Metres Grading 0.95 g/t AuEq While Targeting Inferred Material Within the Z87 Reserve Pit
Troilus advances Z87 optimization drilling as its $1.2 billion debt mandate nears finalization.
Troilus Mining Corp. announced the initial results from its Z87 reserve pit optimization drill program, which comprised 13 holes totaling 3,718 meters. The program targets historically unsampled hangingwall intervals and inferred mineralization within the Z87 reserve pit to support mine planning, resource conversion, and operational optimization for the planned 50,000 tpd operation. This initial phase represents approximately 15% of the total expected metres for the Z87 optimization program.
Key intercepts include: - 157.5 m @ 0.95 g/t AuEq
The results aim to upgrade inferred resources to indicated categories, improve strip ratios, and provide early-year mill feed flexibility.
The drill results align with Troilus Mining Corp.’s (TLG) stated 2026 exploration program, which allocated approximately 10,000 meters to Z87 hanging-wall optimization. The findings are considered incremental and expected, serving to de-risk the mine plan rather than introduce new discovery upside. There was no material surprise in grade or continuity, as the focus remains on optimizing existing reserve pits instead of significantly expanding the resource base. The news aligns with previous guidance and does not alter the project's development timeline or financing requirements.
Troilus Mining Corp. is developing the Troilus Copper-Gold Project in north-central Quebec, situated within the tier-one Frôtet-Evans Greenstone Belt. The project encompasses a 435 km² land position and is underpinned by a May 2024 Feasibility Study that outlines a 22-year, 50,000 tpd open-pit operation. Projected production averages 303,000 AuEq ounces annually, equivalent to 135.4 million lbs CuEq, with a peak output of 536,400 AuEq ounces.
The company has completed basic engineering and advanced into detailed engineering, while also securing a 70 MW hydroelectric power allocation from Hydro-Québec. The project is positioned as one of the largest undeveloped gold-copper projects in Canada, with significant economic and employment impacts projected for the region.
