Hercules Property Secondary Hypogene Enrichment Thickens At Center Of System

TORONTO – Hercules Metals Corp. reported on its first completed hole of the 2025 drilling season at its flagship Leviathan porphyry copper discovery on its Hercules Property in western Idaho. A 220 m step-out hole, HER-25-02, intersected high-grade mineralization consisting of 81 m grading 1.5% Cu and 8.9 g/t Ag, within a larger interval of 127 m grading 1.1% Cu and 7 g/t Ag, which sits within a broad zone of 346 m grading 0.66% Cu, 3.2 g/t Ag and 78 ppm Mo. The upper high-grade subintervals are associated with strong bornite-chalcocite hypogene enrichment mineralization at the centre of the system. Hole 25-02 has extended the strike length of the system to 1.3 km, while a series of northwest-oriented fences are now targeting extensions of this high-grade centre along strike to the south, at 200 m spacing.
Chris Paul, CEO and Director, said, “The results from the first hole of Hercules’ 2025 drill program show not only strong grades unique to the Leviathan porphyry, but also provide evidence that the secondary hypogene enrichment thickens at the centre of the system. These results are a credit in large part to our team’s development of the robust 3D geological model this winter, which allowed us to systematically home in on this high-grade centre. Thus far, the model has resulted in a significantly greater understanding of the controls on mineralization, which we expect will translate into further exploration success moving forward. I look forward to providing additional updates over the next several months as results will now continue to come in.
As we continue vectoring in on the high-grade center, it appears we’re only just beginning to comprehend the scale of this newly-discovered porphyry system. The new Property-wide MT survey announced in August has demonstrated a remarkable correlation with drilled mineralization, which not only provides added confidence in the model, but suggests the potential to extend it upwards of 5 km in total strike length.
“Additionally, porphyry systems occur in clusters, and we’re seeing a multitude of evidence for the potential to discover additional centres within a large north-south copper trend on the Hercules Property. With the help of modern advancements in deep-seeking MT geophysical technology, we’re able to continue expanding on the large Leviathan system as we work to discover more high-grade results along trend.”
