Hercules Metals Corp. has announced significant updates from its ongoing drilling operations at the Leviathan porphyry copper project in western Idaho. These findings stem from the company’s innovative exploration strategy, which has resulted in extensive intervals of continuous copper mineralization observed at relatively shallow depths. Additionally, the discovery of widespread silver in the cover rock has generated renewed interest in the project’s potential as a larger open-pit mining target.
The recent drill results, particularly from drill hole HER-25-05, revealed a remarkable intersection of 273 meters yielding 0.60% copper, along with 77 ppm molybdenum and 1.8 g/t silver. This impressive interval is part of a broader section of 379 meters averaging 0.50% copper. Notably, it includes a concentrated segment of 35 meters that grades 1.01% copper and 6.2 g/t silver. The mineralization starts at a true depth of just 110 meters, indicating potential for accessible resources.

Exploration advancements and ongoing results
In addition to the findings from HER-25-05, drill hole HER-25-03, located further along the same drill fence, produced notable results, intersecting 256 meters with an average of 0.44% copper, 85 ppm molybdenum, and 0.9 g/t silver. This interval is part of a larger section of 452 meters grading 0.37% copper. These results demonstrate the continuity of mineralization across both the Hanging Wall and Footwall zones, supporting the effectiveness of the new exploration model.
Methodology and future prospects
The systematic approach employed involves a grid-based drilling strategy, allowing for precise targeting of high-grade mineralization. This method enhances understanding of the mineralization’s continuity and facilitates identification of the highest-grade cores within the drilling fences. With additional samples currently undergoing assays and drilling activities continuing, the company expects further positive results.
Potential for larger-scale operations
Hercules Metals is also assessing the implications of rising silver prices, which have sparked interest in viewing the Leviathan project as a larger-scale open-pit target. The overlying cover rock, which includes significant low-grade silver, is viewed as a valuable addition to the deeper copper porphyry mineralization. This renewed perspective is supported by initial metallurgical tests indicating that the silver in the Hercules Rhyolite is amenable to extraction through standard processes.
Before the discovery of the Leviathan porphyry, the Hercules Project was primarily viewed through the lens of silver mining potential, backed by over 300 historical drill holes validating extensive silver mineralization within the Hercules Rhyolite unit. Comprehensive drilling conducted in 2022 confirmed historical grades and widths, providing a solid foundation for future exploration efforts.
Looking ahead
Hercules Metals is awaiting assay results from several additional drill holes, which will further delineate the extent of mineralization across the project. The company is optimistic that the completion of the current drilling campaign, including six drill fences spaced at 200 meters, will lead to a maiden mineral resource estimate. This strategic positioning indicates that Hercules Metals is focusing not only on immediate findings but also on laying the groundwork for long-term exploration and resource development.
Hercules Metals’ rigorous exploration initiatives at the Leviathan porphyry system are yielding significant results, with substantial copper and silver intersections. The combination of an innovative drilling strategy and favorable market conditions for silver positions the Hercules project as a compelling opportunity for further exploration and development.
