Hercules Metals Intersects 670 m of 0.45% Copper, 4 g/t

Ag and 95 ppm Mo, including 213 m of 0.67% Copper,

10 g/t Ag, 128 ppm Mo at the Leviathan Porphyry

System in Idaho

Longest Interval to Date, Now Being Extended Further Downhole,

Beginning at a True Depth of 150 m Below Surface

• Assays to 842.65 m depth for drill hole HER-25-18 have been received, returning the

longest interval to date at Hercules:

➢ 670.44 m of 0.45% Cu, 4.0 g/t Ag, 95 ppm Mo

➢ including 212.81 m of 0.67% Cu, 10.2 g/t Ag, 128 ppm Mo

• Represents a 200 m step-out southwest of recently reported drill hole HER-25-15,

which intersected 420.62 m of 0.60% Cu, 6.0 g/t Ag, 65 ppm Mo.

• Hole now being extended beyond 842.65 m as part of the 2026 campaign.

• Upon completion of HER-25-18’s extension, a further 200 m step-out will be drilled from

pre-collared hole HER-25-21.

Toronto, Ontario / March 30, 2026 – Hercules Metals Corp. (“Hercules” or the

“Company”) (TSX-V: BIG) (OTCQB: BADEF) (F RA: C0X) is pleased to report additional

drill results from its 2025 exploration campaign at the Leviathan porphyry copper system,

located on its 100%-owned Hercules Property in western Idaho (the “Property”).

Drill hole HER-25-18 has returned the longest mineralized interval encountered to date at

Leviathan, intersecting 670 metres grading 0.45% copper, 4.0 g/t silver, and 95 ppm

molybdenum, including 212.81 metres grading 0.67% copper, 10.2 g/t silver, and 128 ppm

molybdenum. The intercept begins at a true vertical depth of approximately 150 metres

below surface and remains open further down hole , with drilling currently being extended

beyond 842.65 metres.

HER-25-18 was drilled as a 200 metre step-out to the southwest of previously reported hole

HER-25-15 and now demonstrates strong continuity of copper mineralization across the

rapidly growing footprint of the Leviathan system. The hole intersected sustained copper

mineralization over a broad interval, with higher -grade zones occurring on either side of a

larger mineralized envelope, consistent with the Company’s evolving porphyry model.

Drilling remains ongoing in HER-25-18, which was paused in mineralization at the end of

the 2025 season. A further 200 metre step-out is planned to be completed next, using pre-

collared drill hole HER -25-21, to target the continuation of mineralization along the same

southwest trend.

Chris Paul, President and Chief Executive Officer of Hercules Metals , “HER-25-18

represents a significant leap forward in terms of scale and continuity at the Leviathan

system. Intersecting 670 metres of continuous mineralization in a 200 metre step -out

demonstrates dimensions well beyond our previous understandings of the system.

“In addition, we are now further extending the high-grade upper portion of the system, where

mineralization begins at relatively shallow depths, and continuing to see strong potential for

continued growth along strike to the southwest.

“With additional step -outs planned at Leviathan a nd a growing pipeline of high -priority

targets across several kilometres of untested strike, we are focused on continuing to

systematically expand the Leviathan discovery while vectoring in on new and exciting targets

across our broader land package this season.”

2025 Reconnaissance Drilling

A series of reconnaissance drill holes were completed south of Leviathan, following an initial

Phase I magnetotelluric (“MT”) survey completed at the start of the 2025 field season . The

Phase I survey outlined a corridor of elevated conductivity associated with the Leviathan

copper porphyry system, which also extends for another 5 kilometers to the south.

Subsequent Phase II MT surveying, completed at higher resolution at the end of 2025,

refined this anomalous corridor into a series of discrete, vertically extensive conductive

centers. One of the most prominent, the Southern Flats target, has emerged west of the

2025 reconnaissance holes HER-25-06, HER-25-16, HER-25-22, and HER -25-23 (Figure

1).

HER-25-06, the westernmost hole for which assays have been received, did not reach the

intended target depth for porphyry mineralization but was drilled immediately adjacent to the

newly delineated Southern Flats conductive center and returned significant silver-lead-zinc

mineralization within the overlying cover sequence, including the following previously

reported intervals:

➢ 10.7 m of 257.2 g/t Ag, 2.18% Pb, and 4.62% Zn (420.5 g/t AgEq)

➢ Within 119.9 m grading 31.2 g/t Ag, 0.29% Pb, and 0.86% Zn (59.7 g/t AgEq)

Drilling to the east, in other reconnaissance holes HER-25-16, HER-25-22, and HER-25-23,

encountered strong concentrations of epithermal pathfinder elements in the cover

sequence, and distal skarn alteration in the underlying porphyry target sequence, consistent

with the outer margins of a potential porphyry copper center.

Interpretation of these reconnaissance holes , in conjunction with the newly delineated

Southern Flats conductive center , signals a vector toward increased prospectivity to the

west, as is now being tested by the currently in-progress drill hole, HER-25-25.

Sample Analysis and QAQC

All drill core samples were prepped and analyzed at MSA Labs in Elko, Nevada and/or

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 85%

passing a 75 micron sieve. Following preparation, assays were determined by the IMS-230

method. A 0.25 g aliquot of the prepared pulp was digested in a 4 -acid solution consisting

of hydrochloric, nitric, perchloric and hydrofluoric acids. 4-acid is a near total digest and only

the most highly resistant minerals are not dissolved. The resulting solution was analyzed via

ICP-MS and ICP -ES for 48 elements and was corrected for inter -element spectral

interferences. Lower detection limits for this procedur e are 0.01 ppm for silver, 0.5 ppm for

lead, 2 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 g 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 >1% for copper, lead and zinc.

A 30-50 g split from the crushed and pulverized samples are composited into larger

300-500 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).

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.
