Hercules Metals Intersects 420 m of 0.60% Copper and 6 g/t Ag, Including 113 m of 1.38% Copper and 14 g/t Ag at the Leviathan Porphyry System in Idaho
Hercules Expands Copper Footprint as High-Grade Leviathan Intercepts De-risk Maiden Resource Path
The February 4, 2026, news release reports significant drilling results from the Leviathan porphyry system at the Hercules property in Idaho. Key intercepts include hole HER-25-15, which returned 420.62 meters of 0.60% Copper (Cu) and 6.0 g/t Silver (Ag), including a higher-grade core of 112.78 meters at 1.38% Cu. Additionally, hole HER-25-17 returned 585.22 meters of 0.39% Cu, with a high-grade interval of 46.03 meters at 2.17% Cu. The company also announced the completion of its Phase II Magnetotelluric (MT) survey, which identified five new high-conductivity centers, and initiated discussions for an "order-of-magnitude" study to support a future maiden resource estimate (MRE).
The impact of this news is Material - Positive for several reasons: - Continuity and Grade: The 420m intercept confirms that the mineralization is not only thick but carries a grade (0.60% Cu) that is highly competitive for North American porphyry deposits. The inclusion of >1% Cu over 112m suggests a robust high-grade core. - Exploration Scalability: Management estimates that less than 20% of the target area has been drill-tested. The identification of five new MT conductive centers suggests the system could be part of a much larger district-scale complex, rather than a single isolated deposit. - De-risking: The transition toward an "order-of-magnitude" study indicates the company is moving from "blind" exploration to resource definition. - Operational Readiness: Signing a 2026 drill contract with Dorado Drilling ensures continuity of operations and cost management into the next season.
Hercules Metals is focused on the Hercules Property in western Idaho. Its flagship project is the Leviathan Porphyry discovery. Originally explored for near-surface silver, the project was transformed by the discovery of a large copper-molybdenum porphyry system at depth. The property now covers over 100,000 acres following a massive land consolidation deal with Barrick Gold in 2025. The geological thesis centers on "telescoped" hypogene enrichment, which allows for higher copper grades than typical porphyry systems.
