Positive Update On Drilling Campaign At The Hercules Property

TORONTO - Hercules Metals Corp. reported on drilling from its 2025 field season at its Hercules Property in western Idaho. The Company reports that initial drill holes from the 2025 drilling campaign are validating the breakthrough 3D geological model announced in April 2025, and as a result, the Company has elected to ramp up production from three (3) to five (5) drill rigs. Two drill holes, (25-02 and 25-03), have been completed, and five are currently in progress (25-04, 25-05, 25-06, 25-07, and 25-08). 25-03 tested a gap in the block model, at a favourable orientation to cross-cut the mineralization, while 25-02 completed a 220-metre step-out to the northeast of 24-12. So far, over 3,000 metres have been drilled in 2025.

Importantly, northwest-oriented drilling is validating the 3D geological model developed by the technical team over the winter - now defining a shell of copper-molybdenum (Cu-Mo) mineralization around a central porphyry intrusion. Five drill rigs (four core and one Reverse Circulation (RC) are now testing the system across 2.2 kilometres of strike. This increase, from three drill rigs at the outset of the 2025 campaign, accelerates production and reduces the all-in cost per metre.

RC pre-collars are now being used to efficiently advance through the cover sequence. Shortly after securing the RC contract early in the season, the Company elected to halt core drilling of hole 25-01 and reinitiate drilling with the RC rig on an adjacent pad (25-07), improving overall efficiency. Approximately 1.3 kilometres of known strike are now being better defined, with a renewed focus on the dominant structural control identified in the Cu-Mo block model, highlighting strong grade potential around the contacts of the porphyry intrusion.

A series of step-out drill holes are also targeting along strike extensions, where chargeability and magnetic data highlight compelling growth potential under cover. Ongoing targeting continues to support potential for additional, untested porphyry centres beneath both the Eastern Block and Western Deeps zones. The Eastern Block is defined by several kilometres of anomalous soil and rock chip geochemistry, while the Western Deeps hosts a parallel chargeability high that exceeds Leviathan's anomaly in both size and amplitude.

Chris Paul, CEO and Director, said, "Our 2025 campaign is off to an encouraging start. Initial drilling intercepts have demonstrated enough consistency with the geological model to confidently ramp up to five drill rigs and accelerate the program.

We commenced the program with a series of high-priority holes, aimed northwest, testing a newly developed southeast-dipping structural model. As predicted by the model, holes have now intersected a shell of copper and molybdenum mineralization surrounding a central porphyry intrusion, bracketed on either side by a classic porphyry-style pyrite halo. Early indications also show a general trend of increasing grade around the porphyry's contacts - a structural control which remains largely untested by previous drilling.

"We are now fully focused on rapidly delineating the full extent of the system and concurrently testing for higher-grade controls. Our objective is to better define true thickness along approximately 1.3 kilometres of known strike at Leviathan, while extending the system along trend where anomalous chargeability and magnetic data continue.

I want to commend our technical team for an outstanding geological model developed over the winter, and their cost-effective management of the ongoing drill program. In a short period of time, they've significantly improved both targeting accuracy and overall drilling productivity. We have a substantial amount of drilling still ahead of us, and I look forward to providing further updates as the season progresses."
