Hercules Metals Completes District-Scale MT-NSIP
Survey on Hercules Property, Idaho
Enhanced survey method enables imaging at depths of up to 6 km
Toronto, Ontario / July 9, 2025 – Hercules Metals Corp. ( “Hercules” or the
“Company”) (TSX-V: BIG) (OTCQB: BADEF) (FRA: C0X) is pleased to announce the
successful completion of a large -scale (> 100 square kilomet re) magnetotelluric and
natural-source induced polarization (“ MT-NSIP”) geophysical survey by Moombarriga
USA (“M-Geo”) over the Company’s Hercules Property in western Idaho (the “Property”),
including its flagship Leviathan porphyry copper discovery and newly-added claims. An
additional 20 square kilometres was surveyed on the adjacent Cuddy Mountain property1,
held by Scout Discoveries Corp. (“Scout”), as part of a collaborative survey initiative.
The combined 120 km² dataset is now being processed and inverted as a single
contiguous block, which allows resistivity to be reliably modelled to depths of up to six (6)
kilometres, significantly beyond the ~ 800-metre penetration achieved from the
conventional DC-IP survey completed in 2023.
Survey Highlights
• Expanded Coverage: The 120 km² MT-NSIP survey expands upon the previous
12 km² and 11 km² DC-IP grids completed by Hercules and Scout, respectively.
• Superior Depth Penetration : By utilizing long -wavelength natural currents, MT -
NSIP enables imaging at depths an order of magnitude greater than the previous
active-source DC-IP methods.
• MT Resistivity Applications:

cautioned that mineral deposits on adjacent properties are not indicative of mineral deposits on the Company’s properties.
1. Mapping of regional fault structures and structural intersections.
2. Advanced interpretation of alteration zonation . P orphyry cent res often
present as a conductive phyllic halo surrounding a resistive potassic core.
• NSIP Innovation: NSIP is a novel emerging method to derive deep chargeability
data, up to two (2) kilometres depth , using the same natural-source input as MT.
Partially funded by a third party, this survey may serve as a pioneering industry
case study if its results prove successful. The survey aims to explore for extensions
of the Leviathan porphyry and potentially identify other centres associated with
disseminated sulfide mineralization, which may occur within the project area.

Discussion and Preliminary Analysis
The decision to collaborate with Scout on a broader regional survey served two strategic
purposes:
1. Regional Fault Targeting: Modelling at this scale enhances the ability to interpret
large structural corridors, which often serve as conduits for porphyry emplacement.
With Hercules' significantly expanded land position (see Hercules March 4, 2025
news release), the potential for additional concealed centres can now be further
unlocked.
2. Enhanced Depth Resolution : The broader survey area increases the effective
survey aperture (area), which enables significantly deeper geophysical imaging.
Preliminary Resistivity Results and Insight
M-Geo has delivered a p reliminary resistivity data set ahead of the inversion modelling ,
revealing several key insights:
1. Regional fault structures cut northeast and northwest across the Property ,
indicating potential district-scale structural controls.
2. A conductivity anomaly associated with the Leviathan Porphyry indicates
expansion potential along trend, and provides a baseline for evaluating the
prospectivity of other new anomalies across the Property.
3. A prominent resistivity high has emerged beneath a multi-kilometre soil and rock
chip anomaly in the Eastern Block Zone.
• The anomaly appears consistent with a potential buried intrusive stock.
• New surface mapping demonstrates a folding pattern consistent with
doming, which may support the presence of an underlying intrusive stock.
• Ongoing inversion of the resistivity data will better define the anomaly’s
geometry, and if successful, chargeability data may indicate the presence
of disseminated sulfides.
Next Steps
With field acquisition complete, inversion modelling is underway. Results will be
integrated with the Company’s existing geological, geophysical and geochemical
datasets. The Company anticipates that this integration will yield targets for additional
porphyry centres on the expanded Hercules land package.
