Hercules Metals Announces Positive Results of Induced
Polarization Survey at New Targets, Hercules Project,
Idaho
New Survey Shows IP Chargeability Coincident with MT Conductivity
Anomalies at Pegasus and Hook Targets, with Inaugural Drilling
Commencing in the Coming Weeks
• New Pegasus and Hook targets, situated along strike from the Company’s
Leviathan porphyry copper discovery , are now drill -ready, following results of a
~17-line-kilometer IP survey.
• Rapidly completed multi -phase MT and IP surveys reveal the targets are both
conductive and chargeable , with a similar scale and geometry to the original
Leviathan discovery.
• At the Hook target, a previously announced MT conductivity anomaly (~400 ohm-m)
was surveyed with IP, revealing coincident strong chargeability (up to 25 mV/V)
starting near surface . The anomaly measures approximately 1km along -line and
remains open to the north, east and south.
• At the Pegasus target, a stronger MT conductivity anomaly ( <100 ohm -m) was
surveyed, re vealing an anomalous chargeability response (10-15 mV/V) starting
200 m below surface.
• Rapid pace of new target definition continues, with drilling ongoing at Southern Flats,
inaugural drilling commencing at Pegasus in the coming weeks, and drilling at Hook
to follow thereafter.
Toronto, Ontario / April 22, 2026 – Hercules Metals Corp. (“Hercules” or the
“Company”) ( TSX-V: BIG) (OTCQB: BADEF) (F RA: C0X) is pleased to announce the
results of a recently completed induced polarization (“IP”) geophysical survey, covering two
2
newly identified magnetotelluric (“ MT”) conductivity anomalies (See NR dated Feb 19,
2026), situated along strike from its Leviathan copper porphyry discovery, on its 100%
owned Hercules Property in western Idaho (the “Property”).
The purpose of the IP survey was to further evaluate the prospectivity of two recently
identified MT conductivity anomalies, by testing for the presence of chargeability, a physical
property typically associated with porphyry copper mineralization , and importantly, a key
characteristic of the Company’s Leviathan copper discovery.

IP survey completed over the new Pegasus MT anomaly, that returned a chargeability anomaly ranging from 10 -
15 mV/V in strength. Northeast: A single reconnaissance IP line (georeferenced cross-section) at the new Hook
MT anomaly, showing a strong chargeability anomaly ranging from 12-25 mV/V, which is a similar intensity to the
original Leviathan discovery. Initial planned holes designed to test each new target are shown with a white collar.

the excellent agreement where both surveys overlap. Also shown is MT conductivity (<400 ohm-m) in yellow. An
initial planned hole is designed to test the Hook chargeability anomaly at depth, utilizing road access to the west.

the association with anomalous chargeability. The IP survey has a shallower depth of investigation than MT, but
together show a south-plunging anomaly, similar in geometry to the Leviathan discovery.
Dillon Hume, VP Exploration for Hercules Metals, “The new IP chargeability results at
Hook and Pegasus provide increased confidence in the prospectivity of both targets, which
4
previously were only defined by conductivity. The presence of overlapping conductivity and
chargeability increases the probability of a porphyry copper source to the anomalies.
Property-scale mapping and modelling suggest the anomalies to be hosted in the same age
Triassic host rocks as the Leviathan discovery, with both anomalies showing a similar south-
plunging geometry to the Leviathan porphyry copper system.
The Hook target is further strengthened by close proximity of molybdenum-bearing quartz
veins surrounding the landslide-concealed area.
We’ve designed initial planned holes, utilizing existing roads located at each target. Pegasus
has a road traversing directly over the strongest portion of the anomalies, while Hook has a
road that allows drilling of an angled hole directly at the overlapping anomalies.
We plan to continue drill testing the Southern Flats MT target with one drill rig, while utilizing
our second rig to begin testing these new drill-ready targets, beginning with Pegasus, in the
coming weeks.”
Pegasus Target
The untested Pegasus Target is located several kilometers southeast of the Leviathan
discovery and the adjacent Southern Flats target, where drilling is currently active.
Pegasus is characterized by a strongly conductive MT anomaly, with resistivities of less than
100 ohm-m, as defined by two phases of MT surveying in 2025. The MT anomaly also occurs
within the depth of investigation of IP, which was utilized to test for the possible presence of
a coincident chargeability response.
The IP survey was successful in returning a 10-15 mV/V chargeability anomaly, which is
lower amplitude, but still similar to much of Leviathan, including areas of strong hypogene
mineralization. Chargeability is affected by many factors, including the conductivity of the
cover rocks, and the abundance of associated pyrite. As a result, the contrast of a
chargeability response, relative to background, is often considered a more important
measure of a targets prospectivity, rather than absolute values themselves. In the case of
Pegasus, the overlap of anomalous chargeability with a previously identified MT conductivity
anomaly, ranks it as a high-priority drill target.
Pegasus sits hidden beneath post -mineral basalt cover in a completely untested zone on
the Property. An initial blind drill hole will test for concealed porphyry mineralization as well
as the potential for hypogene enrichment , similar to that found at the Leviathan porphyry
5
copper discovery. Of note, copper skarn mineralization is known to occur at the Climax Zone
on the adjacent Cuddy Mountain property1, approximately 1 kilometer to the east.
All necessary permits, including approval from the Idaho Department of Lands, have been
received, enabling drill testing of the Pegasus target to commence in early May.

Hook Target
The Hook target was initially identified in 2024 , when a nomalous molybdenum -bearing
quartz veins were found along the edge of a landslide-covered area. Follow-up prospecting
in 2025 later identified a small subcrop exposure with porphyry -style alteration and quartz
veining. Quartz-molybdenum veins tend to form a broad halo around the Leviathan
discovery, making them a potential indicator of the outer portions of a porphyry system.
Similar to Pegasus, the Hook target is also located approximately 1 kilometer northwest of
a separate copper skarn occurrence on the adjacent Cuddy Mountain property1, known as
the Railroad.
Following completion of the two phase MT survey in 2025, a significant conductor was
revealed beneath the landslide -covered area. As a result, a single IP line was completed
over the target in March of this year. Remnant snow cover at the time precluded further cost-
efficient production and additional surveying was therefore postponed until mid-spring.
Results of that single IP line have since returned a strong chargeability anomaly, similar in
amplitude to the original Leviathan anomaly, which was tested with the initial discovery hole,
HER-23-05, in 2023.
Chargeability at Hook occurs closer to surface, than other targets on the property, and is
open to the north, east and south. Planning for additional IP lines is underway , to begin
mapping out the full scale of the new anomaly.
Drilling is anticipated to commence at Hook in early summer, following completion of the
additional survey lines.
