HER-25-25 Intersects New Blind Copper Porphyry System at Southern Flats Zone, Hercules Project, Idaho

New Mineralized Center: HER-25-25 has intersected alteration and veining consistent with the outer margins of a new porphyry center, with step-out drilling underway to vector towards the causative porphyry intrusion. Distinct Style: The style of mineralization is distinct from that at Leviathan, with a greater proportion of quartz vein-hosted mineralization and stronger grades than would typically be observed on the margins of the Leviathan system. Increasing Alteration Intensity: Reconnaissance drilling, from east to west at Southern Flats, has systematically vectored from distal propylitic, through phyllic, to outer potassic alteration in HER-25-25, indicating drilling is progressing west toward a new porphyry center.

Increasing Vein Intensity: Concurrent with the alteration zoning, veining intensity has increased from pyrite-rich D-type veins in the east, to high-temperature early halo and B-type veins carrying copper and molybdenum, in HER-25-25. Increasing Chalcopyrite-to-Pyrite Ratios: The ratio of chalcopyrite (copper sulfide) to pyrite (iron sulfide) increases westward into HER-25-25, as well as downhole, coincident with the onset of outer potassic alteration, prior to the hole being stopped by a post-mineral fault zone. 200 m Step-Out Underway: A new step-out hole, HER-26-01, is collared 200 m west of HER-25-25 and has reached the top of the target zone where it is now testing for increasing alteration, veining and mineralization. Significant Scale Potential: HER-25-25 is the first hole to test the edges of a central <30 ohm-m Southern Flats MT conductivity anomaly, which measures approximately 2.6 km long by 1.3 km wide by 1.2 km deep, highlighting significant exploration potential at the newly discovered zone.
