Growth Targeting At Leviathan With Breakthrough 3D Model & Drill Campaign

TORONTO - Hercules Metals Corp. reported the completion of the first 3D block model of the Leviathan discovery on its Hercules property in western Idaho. This milestone provides a clear framework to guide a fully funded 12,000-meter drill campaign, marking a major step toward expanding the discovery and unlocking the broader resource potential of the Leviathan porphyry system.

The 3D block model reveals a coherent, kilometer-scale NE-SW trending porphyry system, providing a strong framework ahead of the 2025 drill campaign. Complexity is greatly reduced to a simple, cohesive southeast-dipping shell of mineralization around a central porphyry intrusion. Near-perfect correlation with both chargeability and magnetics, providing strong validation of the model and the major expansion potential highlighted for 2025.

The 12,000-meter drill campaign launching imminently, with an estimated budget of $6.6 million, including all-inclusive drilling rates which greatly reduce the Company's budgetary risk moving forward. Program designed to systematically grow the central Leviathan Porphyry with a series of 200m spaced fences that expand into both the Grade Creek and the Southern Flats zones, while also testing conceptual models of additional porphyry centers in the Eastern Block and Western Deeps. Drilling will be oriented northwest for the first time ever - expected to significantly increase consistency and hit rate of the southeast dipping mineralization. Joint IP and MT survey set to begin May 1, expanding deep geophysical coverage across the new broader expanded land package.

Chris Paul, CEO and Director, said, "This 3D model represents a major milestone in the evolution of our exploration at Leviathan. Last year, we followed up on our blind discovery with broad-based testing of various zones, drilling in various orientations, in an attempt to understand the trend of concealed mineralization. Blind drilling is always challenging, especially in a new belt, but oriented core has enabled us to systematically map the geometry of the system in 3D. Combined with other data, this allowed us to use the offseason to build a reliable 3D model that gives us far greater confidence heading into the 2025 drill season. Approaching drilling with a systematic, fence-based strategy aimed at delineating an existing model, we expect significantly higher hit rates, longer mineralized intercepts, and fewer misses. This renewed confidence has brought a level of anticipation we haven't felt since the initial discovery in 2023."
