Seven Completed Survey Lines Highlight a 1.8-Kilometer Anomaly with Geometry and Intensity Comparable to the Leviathan Discovery

• Survey Completed: Approximately 28 line-kilometers of induced polarization ("IP") surveying have now been completed across seven lines at the Hook target, expanding upon a previously announced reconnaissance line which returned exceptionally high chargeability, up to 40 mV/V.

• Strong Continuity: The completed survey has now outlined the chargeability feature extending over a strike length of ~1.8 kilometers.

• Strongest Response Near Surface: The highest-intensity portion of the anomaly, ranging from 20-40 mV/V, is modelled to begin within approximately 100 meters of surface on Lines 1 and 2, providing a near-surface drill target.

• Comparable Geometry to Leviathan Discovery: The completed survey reveals a shallow northeast plunging geometry, with similar scale, orientation and intensity to the IP signature at the Leviathan porphyry copper discovery (Figure 1).

• Drilling Underway: The first drill hole testing the target is currently at 200 meters depth. The anomaly begins approximately 100 m below surface; however, a nearby existing access road is being utilized which requires an estimated 350-400 m drilled length to reach the target zone on the initial test (Figure 4).

Toronto, Ontario--(Newsfile Corp. - July 2, 2026) - Hercules Metals Corp.(TSXV: BIG) (OTCQB: BADEF) (FSE: C0X) ("Hercules" or the "Company") is pleased to announce the final results of seven induced polarization ("IP") geophysical survey lines recently completed at the Hook target, on its 100% owned Hercules Property in western Idaho (the "Property").

The completed survey defines a large, continuous chargeability anomaly that extends across all seven lines and exhibits a geometry that closely resembles the IP signature seen at the Company's Leviathan porphyry copper discovery.

The survey was designed to determine the lateral extents of a new near surface anomaly announced earlier in the year. The final results provide increasing confidence in the potential for additional porphyry mineralization concealed beneath shallow post-mineral cover.

At Leviathan, elevated chargeability is closely associated with both porphyry copper mineralization and a surrounding pyrite alteration halo, making IP one of the most effective exploration tools for concealed porphyry systems on the Property.

Chris Paul, CEO of Hercules Metals, "Encountering continuous chargeability across seven widely spaced survey lines has significantly strengthened our geological confidence in the Hook target. With a geometry and intensity comparable to that at the nearby Leviathan discovery, and strong values beginning within 100 meters of surface, we are excited that drilling is now underway at another large new porphyry copper target in the emerging Hercules district."

Southern Flats Drilling Update

A second drill hole has been completed to a depth of 1,255 m at the new Southern Flats porphyry discovery. Drill hole HER-26-01 successfully extended porphyry mineralization 200 meters west of HER-25-25, where the Company recently announced an intercept of 177 m of 0.66% CuEq1 at a new porphyry center (See NR dated May 26, 2026). Drill core has been sampled and is being shipped to MSA Labs for analysis.

Current geological and geophysical information suggests the system strikes north-south, indicating considerable east-west width to the mineralization, which still remains open on both sides. MT geophysics and preliminary IP indicate the system likely extends for a significantly greater distance north-south along strike.

A narrow porphyry dyke was intersected in HER-26-01, but a large causative porphyry remains to be encountered, suggesting significant scale remains to be defined.

Potential Near Surface Extension at Leviathan

Updated geological modelling has identified strong potential for a southern extension of shallow near-surface mineralization at the Leviathan system, in an area with silver-mineralized rhyolite cover mapped at surface, with only 125 meters estimated true depth to the porphyry target below.

A new step-out hole has commenced to test this prospective extension of Leviathan's hanging-wall enrichment zone, which remains open toward Southern Flats. Drill testing this shallow extension of Leviathan will allow faster turnaround of results from a high value target area, as well as support consistent flow of exploration results from different zones, while assays remain pending at Southern Flats.
