HERCULES METALS PROVIDES UPDATE ON 2025 DRILLING AT THE LEVIATHAN PORPHYRY SYSTEM

Hercules Metals Corp. has provided an update on 2025 drilling progress at its flagship Leviathan porphyry copper discovery on its Hercules property in western Idaho. Sixteen holes have been completed, with one hole in progress at Leviathan and two holes currently in progress on a large new priority target area in the Southern Flats zone. Over 13,000 metres have been drilled to date, with samples for nine holes awaiting assay at the lab.

Chris Paul, chief executive officer and director of Hercules Metals, commented: "I am encouraged by the steady progress of our 2025 drilling campaign. Early validation of our 3-D geological model has enabled us to execute a combined strategy of both definition and pure exploration drilling. By employing a fence-based approach, we are able to pinpoint holes that demonstrate the strongest continuity across each 200-metre section, systematically expanding the deposit and delivering value for our shareholders."

"As we continue to build value through definition drilling, we have also entered the initial phase of exploration on a large new target, with a scale that extends well beyond that of Leviathan itself. This new target, referred to as the Donut anomaly, reveals a strong conductivity signature that spans more than three times the width of Leviathan, underscoring the district-scale potential of this new and emerging porphyry copper belt in the United States."

Definition drilling is beginning to demonstrate continuity in the Footwall zone, both along strike and to depth. Continuous mineralization may potentially extend for upward of one kilometre in the Footwall zone, following completion of the 2025 drill campaign. Drill holes 25-14, 18 and 21 are designed to test this continuity trend, the first of which is in progress and the latter two of which are precollared. Footwall mineralization remains open to the south.

Mineralization also remains open in the Hangingwall zone, south of 2024 drill hole 24-19, where the coincident Leviathan magnetotelluric anomaly increases in both scale and magnitude toward the Southern Flats area. Drill hole 25-16 is currently testing for a southern extension of the Leviathan porphyry into Southern Flats, whereas drill holes 25-22 and 25-23 are designed to evaluate whether the stronger, three-kilometre-wide bull's-eye MT feature (the Donut anomaly) may represent a second and separate porphyry centre. Given the sheer scale of the new MT target, drill testing will continue until one or more complete fences have been established across the entire anomaly.

Drilling contractor

RC drilling has been completed for the season, with three remaining precollared holes still to be advanced with core drilling. Hercules extends its appreciation to Alford Drilling.

Dorado Drilling USA has delivered outstanding performance this season, completing deep holes on schedule and to specification, achieving production targets and meaningful cost savings for the company. Building on this success, a third Dorado rig has been mobilized to site to further enhance productivity through the rest of the campaign. The contract with Scout Drilling has been concluded, and the three most efficient Dorado core rigs will remain active, to maintain a strong and consistent production, through to the end of season.
