HERCULES METALS ANNOUNCES NEW MT SURVEY SIGNALLING POTENTIAL FOR SIGNIFICANT EXPANSION AT LEVIATHAN

Hercules Metals Corp.'s first ground-based magnetotelluric (MT) survey has successfully revealed a strong conductive anomaly at the Leviathan porphyry system on its Hercules property in western Idaho. The 100-plus-square-kilometre MT survey, completed by Moombarriga USA Ltd., expanded well beyond the limits of a prior 12 square km 3-D induced polarization (IP) survey and extended the depth of geophysical investigation from 800 metres to over six km.

• Unique geophysical signature -- A major conductivity anomaly stands out throughout the greater than 100-square-kilometre survey area, coinciding directly with the Leviathan porphyry system.
• Strong correlation with mineralization -- The anomaly aligns remarkably well with copper mineralization drilled along 1.3 km of strike length to date.
• Expands and intensifies -- The anomaly extends several kilometres beyond the current limit of drilling, increasing in both size and strength under the Southern Flats zone, where the company holds surface mining rights.
• Classical donut-shaped feature -- Centred under the Southern Flats zone, a three km wide ring of very high conductivity (less than 100 ohm-m) surrounds a moderately conductive (100 to 200 ohm-m) core -- a classical geophysical donut pattern seen in porphyry copper systems.
• Drill testing under way -- A significant stepout hole, 25-16, is now in progress, starting at the northeast edge of the donut anomaly, with plans to complete an initial two-to-three-hole fence across its three-kilometre width.
• Accelerated 2025 drilling campaign -- Over 9,000 metres of drilling have been completed across eleven deep holes, with four additional holes in progress and RC precollars in use to boost productivity. The program has been expanded beyond the original 12,000-metre target, aiming to achieve the maximum possible production with five drill rigs, prior to seasonal shutdown.
• Near-term assays expected -- Drill results from the initial 2025 drill holes are expected in the coming weeks, following lab delays incurred in the early summer months. Additional results will follow continuously through into Q1 2026.

The MT survey results correlate exceptionally well with southeast-dipping copper mineralization at Leviathan and, importantly, reveal the potential for a major expansion to the south, where the anomaly intensifies and forms a high conductivity ring (to less than 70 ohm-m), over three km in width, under the Southern Flats zone. The anomaly is stronger, broader and significantly more vertically extensive than Leviathan, suggesting potential for an additional large porphyry center.

Chris Paul, chief executive officer and director of Hercules Metals, commented: "The initial results from the expanded MT survey are tremendously encouraging for Leviathan's growth potential. The new donut feature identified is reminiscent of a classic geophysical pattern in porphyry copper systems, where highly conductive mineralization forms a shell around a moderately conductive altered intrusion. For Hercules, this could potentially mean that Leviathan represents only a portion of a much larger system, with the most prospective target concealed beneath postmineral cover in the Southern Flats, where the company holds surface mining rights."

"Ground MT is a powerful tool that provides absolute values of resistivity/conductivity, allowing anomalies to be evaluated based on actual strength, which airborne EM methods are unable to do. In the context of Leviathan, the known mineralization drilled to date is represented by values of approximately 100 ohm-m, considered a moderately strong response in porphyry copper systems. However, porphyry targets become even more interesting when they enter the 'double-digit' range (in example, 99 ohm-m or less), which the MT survey has revealed in a three km wide ring wrapping around the newly identified donut anomaly. This makes it one of the most prospective geophysical targets identified in the district to date, and, as a result, we have immediately commenced drilling the first of an initial two-to-three-hole fence that will be completed across the anomaly's entire three km width."
