Hercules Metals Provides Positive Update on its 2025

Drilling Campaign

2025 drilling validating new 3D geological model; more drill rigs

added to the property

Toronto, Ontario / June 23, 2025 – Hercules Metals Corp. ( “Hercules” or the

“Company”) (TSX-V: BIG) (OTCQB: BADEF) (FRA: C0X) is pleased to provide an

update on drilling from its 2025 field season at its Hercules Property in western Idaho (the

“Property”). The Company reports that initial drill holes from the 2025 drilling campaign

are validating the breakthrough 3D geological model announced in April 2025, and as a

result, the Company has elected to ramp up production from three (3) to five (5) drill rigs.

Highlights

• Two drill holes, (25-02 and 25-03), have been completed, and five are currently in

progress (25-04, 25-05, 25-06, 25-07, and 25-08). 25-03 tested a gap in the block

model, at a favourable orientation to cross-cut the mineralization , while 25-02

completed a 220-metre step-out to the northeast of 24-12. So far, o ver 3,000

metres have been drilled in 2025.

• Importantly, n orthwest-oriented drilling is validating the 3D geological model

developed by the technical team over the winter – now defining a shell of copper-

molybdenum (“Cu-Mo”) mineralization around a central porphyry intrusion (the

“Leviathan Target”).

• Five drill rigs (four core and one Reverse Circulation (“RC”) are now testing the

system across 2.2 kilomet res of strike. T his increase, from three drill rigs at the

outset of the 2025 campaign , accelerates production and reduces the all -in cost

per metre.

• RC pre-collars are now being used to efficiently advance through the cover

sequence. Shortly after securing the RC contract early in the season, the Company

elected to halt core drilling of hole 25-01 and reinitiate drilling with the RC rig on

an adjacent pad (25-07), improving overall efficiency.

• Approximately 1.3 kilometres of known strike are now being better defined, with a

renewed focus on the dominant structural control identified in the Cu -Mo block

model, highlighting strong grade potential around the contacts of the porphyry

intrusion.

• A series of s tep-out drill holes are also targeting along strike extensions, where

chargeability and magnetic data highlight compelling growth potential under cover

(Figures 2 and 3).

• Ongoing targeting continues to support potential for additional, untested porphyry

centres beneath both the Eastern Block and Western Deeps zones. The Eastern

Block is defined by several kilomet res of anomalous soil and rock chip

geochemistry, while the Western Deeps hosts a parallel chargeability high that

exceeds Leviathan’s anomaly in both size and amplitude (Figures 2 and 4).

Chris Paul, CEO and Director of Hercules Metals, commented, “Our 2025 campaign

is off to an encouraging start. Initial drilling intercepts have demonstrated enough

consistency with the geological model to confidently ramp up to five drill rigs and

accelerate the program.

“We commenced the program with a series of high-priority holes, aimed northwest, testing

a newly developed southeast-dipping structural model. As predicted by the model, holes

have now intersected a shell of copper and molybdenum mineralization surrounding a

central porphyry intrusion, bracketed on either side by a classic porphyry-style pyrite halo.

Early indications also show a general trend of increasing grade around the porphyry’s

contacts – a structural control which remains largely untested by previous drilling.

“We are now fully focused on rapidly delineating the full extent of the system and

concurrently testing for higher-grade controls . Our objective is to better define true

thickness along approximately 1.3 kilomet res of known strike at Leviathan, while

extending the system along trend where anomalous chargeability and magnetic data

continue.”

Mr. Paul concluded, “I want to commend our technical team for an outstanding geological

model developed over the winter, and their cost-effective management of the ongoing drill

program. In a short period of time, they’ve significantly improved both targeting accuracy

and overall drilling productivity. We have a substantial amount of drilling still ahead of us,

and I look forward to providing further updates as the season progresses.”

relative to the footwall and hanging wall targets on either side of the central Leviathan Porphyry.

Figure 2: Chargeability – 2025 drilling at the Leviathan Target, relative to chargeability 450m below

surface. The geophysical pattern is consistent with a classical porphyry copper system, with a low

chargeability core flanked by a high chargeability halo. In this case, chargeability extends into the

untested Grade Creek and Southern Flats zones, while a secondary target, the Western Deeps, lies

buried beneath a down dropped fault block to the west.

Figure 3: Drone Magnetics – 2025 drilling at the Leviathan Target, relative to total magnetic intensity.

Similar to chargeability, magnetic data suggests continuity northeast into the untested Grade Creek

Zone and beyond. In the south, magnetic intensity increases before encountering p ost mineral

basalt which conceal the magnetic signature beneath Southern Flats. Chargeability data however

suggests potential for continuity in both directions.
