Hercules Metals (TSXV: BIG) has encountered further copper mineralization at their flagship Hercules property in Idaho. The company this morning released further assay results from their 2025 drill program, which focused on the Leviathan porphyry copper discovery.
Highlights from the latest assay results include:
- HER-25-03: 0.37% copper, 73 ppm molybdenum and 0.86 g/t silver over 452.32 metres from a depth of 181.66 metres
- Including 0.44% copper, 85 ppm molybdenum and 0.9 g/t silver over 256 metres from a depth of 295.66 metres
- HER-25-04: 0.30% copper, 41 ppm molybdenum and 1.0 g/t silver over 85.07 metres from a depth of 236.22 metres
- Including 0.48% copper, 53 ppm molybdenum and 0.9 g/t silver over 38.28 metres from a depth of 283.01 metres
- HER-25-05: 0.50% copper, 75 ppm molybdenum and 1.5 g/t silver over 379.45 metres from a depth of 131.05 metres
- Including 0.60% copper, 77 ppm molybdenum and 1.8 g/t silver over 272.8 metres from a depth of 131.06 metres
- And including 1.01% copper, 32 ppm molybdenum and 6.2 g/t silver over 34.75 metres from a depth of 181.05 metres
Holes HER-25-03 and HER-25-05 are said to have intersected the Hanging Wall Zone, with both holes drilled along the same fence. Another hole, HER-25-15, is also said to have been drilled along this fence, assays for which are pending. That hole is said to delineate the full width of mineralization across the Hanging Wall and Footwall zones.
Five additional fences were drilled under the current drill program, with those fences conducted at 200 metre spacings. The results from this effort are intended to be used to identify the highest grade cores and guide infill drilling.

“We are employing a systematic, fence-based drilling strategy with the objective of delineating where the highest-grade mineralization occurs on each 200 metre-spaced fence. [..] By the end of the 2025 campaign, the Company will have completed a total of six (6) 200 metre-spaced drill fences, at which time, it may evaluate the prospect of initiating a maiden mineral resource estimate,” commented Chris Paul, CEO of Hercules Metals.
“The Hercules Project was initially acquired for its extensive silver mineralization, long before the discovery of the Leviathan porphyry transformed it into one of the most compelling new copper projects in the U.S. With silver prices strengthening, we’re now beginning to see an opportunity to view Hercules as a larger-scale open-pit target, encompassing both the porphyry copper system at depth and the near-surface silver mineralization in the overlying cover rock.”
Hercules Metals last traded at $0.61 on the TSX Venture.
