Hercules Metals Intersects 273 m of 0.60% Copper, within 379 m of 0.50% Copper, Including 35 m of 1.01% Copper and 6.2 g/t Silver at the Leviathan Porphyry System

Hercules Metals announced additional drill results from its 2025 program at the Leviathan Porphyry Copper System in Idaho. The highlights include: - Hole HER-25-05: Intersected 379 meters of 0.50% copper, including a higher-grade core of 273 meters of 0.60% copper and 1.8 g/t silver. This mineralization begins approximately 110 meters below the surface. - Hole HER-25-03: Intersected 452 meters of 0.37% copper. - Hole HER-25-04: Intersected 85 meters of 0.30% copper and was terminated in a late-mineral dyke.

The CEO, Chris Paul, stated that the company's new 3D geological model is driving consistently positive results, building confidence in the grade continuity over a significant strike length. The company is using a systematic, 200-meter spaced drill fence strategy to delineate the highest-grade zones. With assays pending for seven more holes, the company may evaluate initiating a maiden mineral resource estimate after completing six drill fences in the 2025 campaign. The release also noted the potential to view the project as a larger-scale open pit encompassing both the deep copper and near-surface silver mineralization.

This news is materially positive as it successfully demonstrates grade and geological continuity, a critical step in de-risking an exploration project. To understand its full impact, we must review the company's progression over the past year.

• Q4 2024 - Q1 2025: The company was releasing final 2024 drill results (e.g., Jan 15: 300m of 0.70% CuEq) and focused on geological interpretation, culminating in the completion of its first 3D block model (April 17). This modeling work, along with an independent study confirming hypogene enrichment (May 5), formed the foundation for the 2025 drill program, which was designed to test the new model with a more optimal northwest drilling orientation.

• Q2-Q3 2025: Hercules executed several key strategic moves. It consolidated a massive land package through an option agreement with major miner Barrick Gold (July 28), significantly increasing the project's district-scale potential and bringing in a key strategic partner. This was followed by a substantial C$17.25 million financing at $0.70 per share (August 14), fully funding an expanded 2025 drill program. These actions demonstrated management's ability to advance the project on both the corporate and technical fronts.

• Drilling Results Progression (Q3-Q4 2025): The first drill results of the 2025 campaign, released on September 17, were a blockbuster success, with hole HER-25-02 hitting 81 meters of 1.5% copper within a broader 346-meter interval of 0.66% copper. This was a spectacular hole that validated the new 3D model and set a very high bar for expectations.

The most recent results (October 22) are the crucial follow-up. While the peak grades are not as high as in HER-25-02, hole HER-25-05 delivered a very long interval of strong grade (273 m of 0.60% Cu) that is economically significant for a porphyry system. This result is not a one-off discovery hole; it is a confirmation hole that builds tonnage and proves continuity. By hitting another strong intercept, Hercules has significantly reduced the risk that HER-25-02 was an isolated high-grade pod.

The systematic fence-based drilling approach is logical, and these results support the stated goal of potentially defining a maiden resource. The market needed to see that the company could consistently hit mineralization, and this release delivers on that. It solidifies Leviathan as one of the more compelling new copper discoveries in the United States.

Hercules Metals Corp. is a Canadian-based mineral exploration company focused on its 100%-owned Hercules Property in western Idaho, USA. Initially explored for silver, the company's focus has pivoted to copper following the 2023 discovery of the Leviathan Porphyry Copper System. The company is now in the midst of a large, systematic drill program aimed at delineating this large-scale copper system, which also has potential for silver and molybdenum credits.
