Hercules Metals Outlines Initial 2026 Drill Plan at the Hercules Property in Western Idaho
-
Phase I Drill Plan – An initial 12,500 m first phase of drilling has commenced at the Hercules Property, testing five new target areas shown in Figure 2, all of which lie along trend from the Leviathan copper system. Upon completion of this phase and evaluation of results, the Company anticipates expanding to a total of 20,000 to 30,000 m.
-
Second Drill Rig Mobilized Ahead of Schedule – A second drill rig has been mobilized to resume drilling at hole HER-25-18, previously paused at 841 m depth. Observations of potassic alteration at depth suggest the potential for a broader Footwall Zone than previously interpreted. The rig has undergone significant winter upgrades, expected to materially improve drilling efficiency (Figure 1).
Toronto, Ontario–(Newsfile Corp. – March 20, 2026) – Hercules Metals Corp. (TSXV: BIG) (OTCQB: BADEF) (FSE: C0X) (“Hercules” or the “Company“) is pleased to provide details on its initial 12,500 m drill program, currently underway at five new target areas along trend from the Leviathan copper discovery at its Hercules Property in western Idaho (the “Property“).
Figure 2 outlines the approximate allocation of planned drilling across the following targets:
-
Leviathan Southwest Extension (~3,000 m) – The Leviathan copper system remains open to the southwest. Drilling will focus on extending known mineralization in this direction and testing for continued system growth.
-
Leviathan’s Footwall MT Anomaly (2,500 m) – Recent drilling at the northern extent of Leviathan has encountered increasing copper grades at depth (see previous news release dated Feb 4, 2026), approaching a deeper northeast-plunging magnetotelluric (“MT“) anomaly that remains untested. At least two deep drill holes are planned to evaluate the source and significance of this anomaly.
-
Southern Flats Target (~3,000 m) – Southern Flats represents the largest and most robust geophysical anomaly identified on the Property to date. Defined through two phases of MT surveying, the target is characterized by a discrete, vertically extensive, cylindrical conductor situated directly along strike to the south of Leviathan. Approximately three deep drill holes are planned to test this target over a meaningful strike extent.
-
Pegasus Target (~3,000 m) – Located several kilometers southeast of Southern Flats, the Pegasus target exhibits a similar MT geophysical signature. A recently completed induced polarization (“IP“) survey has also identified a coincident chargeability anomaly, significantly increasing confidence that Pegasus may represent an untested porphyry center.
-
The Hook Target (~1,000 m) – The Hook target is defined by a moderate conductivity anomaly that returned the strongest chargeability response from the 2026 IP survey. The magnitude of this response is comparable to that associated with the original Leviathan IP anomaly that led to the 2023 discovery hole HER-23-05. Final IP results remain pending, while planning for additional IP is underway.
