Hercules Metals intercepts 788 m of 0.54% CuEQ at Leviathan, Idaho

Drilling and IP Surveying Also Underway at Hook Target, Investigating the Strongest Near Surface Chargeability Anomaly on the Property HER-25-21 extends Leviathan's Footwall Zone to the southwest, returning: 801.6 m of 0.40% CuEq (0.30% Cu, 82 ppm Mo, 5.3 g/t Ag, 0.01 g/t Au) And Incl. 107.8 m of 0.52% CuEq (0.43% Cu, 104 ppm Mo, 1.8 g/t Ag, 0.02 g/t Au) And Incl. 206.3 m of 0.45% CuEq (0.39% Cu, 98 ppm Mo, 0.7 g/t Ag, 0.01 g/t Au) HER-25-18 was also further extended downhole, following a brief winter drilling pause, returning a final composite interval of: 787.9 m of 0.54% CuEq (0.43% Cu, 91 ppm Mo, 3.5 g/t Ag, 0.03 g/t Au) Incl. 212.8 m of 0.89% CuEq (0.67% Cu, 128 ppm Mo, 10.2 g/t Ag, 0.05 g/t Au) High Grades at the Top: All three holes reported in this news release also include high-grade intersected at the top of the system, summarized as follows: HER-25-18 - 57.4 m of 1.18% CuEq , beginning at 188 m downhole (158 m true depth below surface) HER-25-21 - 21.3 m of 2.00% CuEq , beginning at 224 m downhole (214 m true depth below surface) HER-25-24 - 17.8 m of 1.54% CuEq , beginning at 236 m downhole (112 m true depth below surface) System Remains Open: The Leviathan Porphyry remains open for expansion to the southwest, where further step-out drilling is planned for the 2026 season. Drilling Underway at the Hook Target: Reconnaissance drilling has now commenced at the Hook target, to test the strongest chargeability anomaly identified on the Property to date, with values up to 40 mV/V. 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 for the initial test.

IP Survey Continuing: Encouraged by strong initial results at the Hook target, the Company has expanded the IP survey to seven lines cove
