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)
- 801.6 m of
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)
- 787.9 m of
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)
- HER-25-18 - 57.4 m of
- 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 covering 1.7 km of prospective strike length. The chargeability anomaly has now been traced across five completed lines, covering 1.2 km of strike length. The two most recent lines were extended to cross the Leviathan porphyry system as a calibration check, where they returned a near-identical geophysical response.
- Additional IP Lines Planned at Pegasus: Upon completion of the Hook survey, crews will move back to the Pegasus target to conduct a series of long east-west IP lines designed to test the full width of a major structural corridor, within which porphyry mineralization is interpreted to have been emplaced at the Hercules Property.
- First Pegasus Hole Complete: The first drill hole at the Pegasus target, HER-26-02, has been completed. The hole intersected distal porphyry alteration, veining, and mineralization, analogous to early drilling completed at the Southern Flats target, prior to discovering strong copper mineralization to the west in HER-25-25. The upcoming IP survey will test for the presence of near surface chargeability approximately 2 km to the west of HER-26-02, along trend from the same structural zone hosting Southern Flats.
Toronto, Ontario--(Newsfile Corp. - June 16, 2026) - Hercules Metals Corp. (TSXV: BIG) (OTCQB: BADEF) (FSE: C0X) ("Hercules" or the "Company") is pleased to announce further results from its 2026 drilling campaign at the Leviathan Porphyry on its Hercules project in western Idaho (the "Property"). HER-25-21 was completed from a 2025 RC pre-collar, and extended Leviathans footwall zone to the southwest with an intercept 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 at the end of 2025. The final composite assay result for HER-25-18 is:
- 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

1.18% CuEq (1.06% Cu, 112 ppm Mo, 3.6 g/t Ag, 0.04 g/t Au)
Chris Paul, CEO for Hercules Metals, "We're pleased to further extend mineralization to the southwest as the Leviathan porphyry copper system continues to demonstrate its continuity and growth potential. We look forward to completing further ongoing step-outs to the southwest as the 2026 season progresses.
We're also very encouraged by the ongoing IP results at the new Hook target. What initially began as a subtle MT anomaly has quickly evolved into a high priority target, and the first to exhibit a near identical IP response to Leviathan. We look forward to receiving the final survey results once the remaining lines are completed, after which the crew will return to the Pegasus anomaly to investigate the potential for additional near-surface mineralization."

Hook IP Anomaly
A new 2026 IP survey at the Hook target has identified a strong, continuous, near-surface chargeability anomaly exhibiting a geophysical response strongly analogous to the Leviathan porphyry copper system in terms of scale, strength, geometry, and orientation. The anomaly is located approximately 3 kilometers east of, and subparallel to, the Leviathan porphyry system and its associated chargeability signature (Figure 8).
To validate the comparison, IP lines 4 and 5 were extended to also cross over the Leviathan system as a calibration check, where they returned a highly comparable response, with both zones showing chargeability values ranging from 16-19 mV/V (Figures 6 and 7). Upcoming IP lines 6 and 7 will look to extend both the Hook and Leviathan anomalies further north.
IP lines 1 through 3 were run exclusively across the Hook target, where the strongest chargeability anomaly on the Property has been returned, with values of up to 40 mV/V (Figures 3-5).
Drilling has now commenced in hole HER-26-03, to test the area of strongest chargeability between IP lines 1 and 2 (Figures 3, 4, and 8). The anomaly begins within 100 m of surface on these lines; however, the first hole is collared from the nearest existing access road which requires an estimated 350-400 m drilled length to reach the target zone. If initial drilling is successful, the Company will evaluate options for permitting and constructing new temporary roads directly across the anomaly, to test where it comes closest to surface.
Figure 3: IP line 1N (looking north) at the Hook target. The >20 mV/V anomaly comes within 100 m of surface, where recent landslide cover conceals the target. The initial drill test in HER-26-03 is collared from an existing access road to the west of the anomaly, requiring an estimated 350-400 m drilled length to reach the target zone.

Pegasus Reconnaissance Drilling
HER-26-02 was collared within an approximately 3 kilometer wide structural corridor, distinguished by strongly elevated MT conductivity, which is host to both the Leviathan and the Southern Flats porphyry copper centers. The hole was collared on the eastern side of the corridor, where it intersected distal alteration and minor quartz-magnetite-pyrite veining, with weak to anomalous copper and molybdenum, consistent with similar results returned from early drilling on the same side of the corridor at the Southern Flats zone.
Drawing on geological insights gained from the discovery of Southern Flats; the western portion of the corridor is interpreted to have certain key structural controls indicative of higher porphyry copper potential. Upon completion of the final two IP lines at Hook, the western side of the structural corridor will be surveyed next, to investigate the potential for associated near-surface chargeability.

Sample Analysis and QAQC
All drill core samples were prepped at MSA Labs in Elko, Nevada and analyzed at MSA Labs in Langley, British Columbia, an ISO 17025 and ISO 9001 certified laboratory. Samples were dried and crushed to 2 mm, from which a 250 g sub-sample split was then pulverized to
Samples with initial results beyond the upper detection limit of the IMS-230 method were analyzed by procedures ICF-6Ag, ICF-6Cu, ICF-6Pb and ICF-6Zn. The thresholds are 100 ppm for silver, and >
A 50 g split from the crushed and pulverized samples are composited into larger 500 g composite samples (consisting of ten continuous samples) and analyzed for gold utilizing CPA-Au1 photon assay method. Certain material gold results from the composite samples are then selected for re-analysis, by individual sample, as a 30 g fire assay (FAS-111 Method). Gold assays below detection limit are treated as zero values for composite calculations.
MSA Labs employs internal quality control standards, duplicates and blank samples at set frequencies.
Blind certified reference materials (CRMs) and blank samples were systematically inserted by the Company into the sample stream and analyzed as part of the Company's quality assurance/quality control protocol.
