HERCULES METALS INTERSECTS 420 M OF 0.60% COPPER AND 6 G/T AG, INCLUDING 113 M OF 1.38% COPPER AND 14 G/T AG AT THE LEVIATHAN PORPHYRY SYSTEM IN IDAHO

Hercules Metals Corp. has released further results from its 2025 drilling campaign on the Leviathan porphyry copper discovery at its Hercules property in western Idaho.

Highlights:

• Thick and continuous footwall mineralization intersected in HER-25-15, returning:
  • 420.62 metres of 0.60 per cent copper, 6.0 grams per tonne silver and 65 parts per million molybdenum;
  • Including 112.78 m grading 1.38 per cent Cu, 14 g/t Ag and 40 ppm Mo;
• Strong hypogene enrichment intersected in HER-25-17, returning:
  • 46.03 m of 2.17 per cent Cu, 16.0 g/t Ag and 44 ppm Mo;
  • Including 6.1 m of 12.52 per cent Cu, 11.3 g/t Ag and 80 ppm Mo;
  • Within 585.22 m of 0.39 per cent Cu, 2.1 g/t Ag and 49 ppm Mo;
  • And ending in 70.1 m of 0.50 per cent Cu and 117 ppm Mo with a final 12.19 m of 0.62 per cent Cu and 142 ppm Mo;
• Phase II MT (magnetotelluric) reveals five discrete conductive centres -- a phase II magnetotelluric and extremely low-frequency electromagnetic (MT+ELF) geophysical survey infilled a multikilometre conductivity anomaly outlined by the initial phase I program; the higher-resolution data now delineate up to five discrete high-conductivity centres within the broader anomaly, which are planned for testing during the 2026 drill season;
• New footwall MT anomaly -- one of the five conductive centres occurs at the northern end of Leviathan's footwall zone; HER-25-17 intersected the top of this footwall MT anomaly, where it terminated in increasing grades away from the lower porphyry contact, ending in 0.62 per cent Cu from 895 m to 907 m (end of hole); nearby holes, including HER-23-08 and HER-24-12, also ended in increasing grades at depth; the footwall anomaly may represent a deep-seated early porphyry centre that has not yet been tested by drilling;
• A 2026 drill contract has been signed with Dorado Drilling USA and plans are under way to recommence drilling once final assays have been received for the 2025 drilling season and an updated 3-D geological model has been completed;
• The company is in discussions with a specialized Vancouver-based consulting firm and plans to initiate an order-of-magnitude study to assess any additional drilling requirements or data set gaps, ahead of commencing an initial maiden resource estimate for both the near-surface silver mineralization and the Leviathan copper porphyry system.

Dillon Hume, vice-president, exploration, of Hercules Metals, commented: "These latest results demonstrate continued expansion of the high-grade hypogene enrichment at Leviathan while highlighting the broader potential for additional porphyry centres across the Hercules land package.

"HER-25-17 showed an increase in both copper and molybdenum grades upon entering what is now revealed to be a large MT conductor at depth, supporting the potential for expansion into new and previously untested zones of concealed copper mineralization.

"Given the scale of the mineral system that has been defined so far, and the multiple conductive centres that have been identified along trend, we estimate that drilling to date has tested less than 20 per cent of the overall target area at Hercules."

Sample analysis and quality assurance/quality control

All drill core samples were prepped and analyzed at MSA Labs in Elko, Nev., and/or Langley, B.C., an ISO 17025- and ISO 9001-certified laboratory. Samples were dried and crushed to two millimetres, from which a 250-gram subsample split was then pulverized to 85 per cent passing a 75-micron sieve. Following preparation, assays were determined by the IMS-230 method. A 0.25-gram aliquot of the prepared pulp was digested in a four-acid solution consisting of hydrochloric, nitric, perchloric and hydrofluoric acids. Four-acid digestion is a near-total digest and only the most highly resistant minerals are not dissolved. The resulting solution was analyzed through ICP-MS and ICP-ES for 48 elements and was corrected for interelement spectral interferences. Lower detection limits for this procedure are 0.01 ppm for silver, 0.5 ppm for lead, two ppm for zinc and 0.2 ppm for copper. Mercury is not reported due to volatilization in reaction with hydrofluoric acid and gold is not reported due to the small, 0.25-gram aliquot size being insufficient to overcome the nugget effect.

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 greater than 1 per cent for copper, lead and zinc.

A 30-to-50-gram split from the crushed and pulverized samples are composited into larger 300-to-500-gram composite samples (consisting of 10 continuous samples) and analyzed for gold utilizing CPA-Au1 photon assay method. Certain material gold results from the composite samples are then selected for reanalysis, by individual sample, as a 30-gram fire assay (FAS-111 method).

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.
