New 2025 Exploration Model Results in Long Intervals of Continuous Copper Mineralization at Shallower Depths with Growing Significance of Widespread Silver in Cover Rock
New 3D model now driving consistently positive results in 2025 drilling -
Drill hole HER-25-05 intersected:
273 m of 0.60% Cu, 77 ppm Mo, and 1.8 g/t Ag,
within 379 m of 0.50% Cu, 75 ppm Mo, and 1.3 g/t Ag,
including 35 m of 1.01% Cu and 6.2 g/t Ag
Drill hole HER-25-03, further outward from 25-05, intersected:
256 m of 0.44% Cu, 85 ppm Mo, and 0.9 g/t Ag
within 452 m of 0.37% Cu, 73 ppm Mo, and 0.9 g/t Ag
Hanging Wall Zone closer to surface - Mineralization begins at a true depth of just 110 m below surface in HER-25-05.
750 metre-wide fence completed - Assays remain pending for drill hole HER-25-15, which completes a 750 metre-wide drill fence.
Building continuity - Drilling with a new exploration model this season is building continuity in both the Hanging Wall Zone (this news release) and Footwall Zone (see Hercules news release dated September 17, 2025), with a systematic grid-based approach that allows vectoring toward the highest-grade centre of each drill fence.
Widespread silver in cover rock - Recent strength in silver prices has renewed interest in the potential to view Leviathan as a larger-scale open-pit target, encompassing the deeper porphyry mineralization together with widespread low-grade silver in the near-surface cover rock.
Additional catalysts ahead - Assay results are now pending for an additional seven (7) completed holes now in the lab, with additional sample shipments ongoing, and drilling continuing.
Toronto, Ontario--(Newsfile Corp. - October 22, 2025) - Hercules Metals Corp. (TSXV: BIG) (OTCQB: BADEF) (FSE: C0X) ("Hercules" or the "Company") is pleased to report further results from its 2025 drilling campaign at the Company's flagship Leviathan porphyry copper discovery, located on its Hercules Property in western Idaho (the "Property").
Results are now demonstrating continuity in the Hanging Wall Zone, with HER-25-05 ("25-05") returning 273 m of 0.60% Cu, 77 ppm Mo, and 1.8 g/t Ag, within a broader interval of 379 m of 0.50% Cu, 75 ppm Mo, and 1.5 g/t silver, beginning at 110 m true depth below surface. HER-25-03 ("25-03"), drilled further outward along the same fence, intersected 256 m of 0.44% Cu, 85 ppm Mo, and 0.9 g/t Ag within 452 m of 0.37% Cu, 73 ppm Mo, and 0.86 g/t Ag.
Assays for HER-25-15 are pending and will complete this fence, delineating the full width of mineralization across both the Hanging Wall and Footwall zones on this section. With five additional fences drilled at 200-metre spacing this season, continuity is building rapidly across the Leviathan system. And, by applying a systematic, model-driven approach, the Company is able to identify and delineate where the highest-grade core is centred on each drill fence, guiding additional infill drilling.
Drill hole HER-25-04 ("25-04") was deemed to have been collared away from the centre, at a dip later determined to be too steep, and was terminated in a late-mineral dyke. However, prior to encountering the late-mineral dyke, assay results revealed a consistent increase in copper within the surrounding volcanic host rock. The final 85 metres immediately preceding the dyke averaged 0.30% Cu, including a final 38 metre interval grading 0.48% Cu, supporting higher grades being located west of 25-04, where the centre of the system is now inferred.
