Reconnaissance Drill Hole HER-26-03 Intersects Intense Phyllic Alteration, Consistent with the

Drill Results

Hercules

Metals

Identifies

Evidence

for

a

New

Porphyry

Center

at

the

Hook

Target

Reconnaissance

Drill

Hole

HER-26-03

Intersects

Intense

Phyllic

Alteration,

Consistent

with

the

Margins

of

a

New

Porphyry

System,

at

the

Edge

of

a

1.8-Kilometer

Chargeability

Anomaly

●

Reconnaissance

Hole

Tests

Edge

of

Anomaly:

Drilling

from

the

nearest

existing

road,

approximately

400

meters

west

of

the

newly

identified

Hook

chargeability

anomaly,

successfully

intersected

strong

quartz-sericite-pyrite

(“phyllic”)

alteration,

consistent

with

the

margins

of

a

potential

nearby

porphyry

copper

system.

●

Advanced

Drill

Permitting

Underway:

The

reconnaissance

hole

was

drilled

from

the

nearest

location

accessible

under

the

Company’s

existing

drill

permit

and

was

designed

to

test

for

distal

porphyry-style

alteration

near

to

the

target.

Based

on

the

strength

of

the

alteration

encountered,

the

Company

has

elected

to

proceed

with

permitting

temporary

access

roads

and

drill

pads

to

directly

test

the

core

of

the

chargeability

anomaly.

●

Target

Size

:

The

Hook

target

comprises

an

approximately

1.8-kilometer-long

IP

chargeability

anomaly,

coincident

with

a

previously

identified

conductivity

anomaly

from

the

Company’s

district-scale

2025

MT

survey.

●

High-Strength

Core:

The

highest-intensity

portion

of

the

Hook

target

extends

for

approximately

500

meters

and

ranges

from

approximately

20–40

mV/V,

representing

the

strongest

chargeability

response

associated

with

Triassic

rocks

identified

on

the

Property

since

the

2023

IP

survey

that

led

to

the

discovery

of

the

Leviathan

porphyry

copper

system.

●

Near

Surface:

The

high-strength

core

of

the

anomaly

is

modelled

to

begin

within

approximately

100

meters

of

surface,

which

is

where

the

next

phase

of

drill

permitting

will

focus.

In

addition,

Triassic-age

host

rocks

are

mapped

at

the

surface

across

the

Hook

target

area.

●

Favourable

Host

Rock:

In

addition

to

quartz-sericite-pyrite,

distal

skarn

alteration

was

encountered

within

favourable

calcareous

host

rocks

in

the

hole.

The

presence

of

skarn

2

alteration

is

encouraging,

as

these

host

rocks

are

generally

conducive

to

strong

mineralization

near

their

porphyry

source.

Toronto,

Ontario

/

September

14,

2026 – Hercules

Metals

Corp. (“Hercules”

or

the

“Company”)

(TSX-V: BIG

|

OTCQB:

BADEF)

is

pleased

to

announce

that

HER-26-03

has

intersected

intense

quartz-sericite-pyrite

(“

phyllic

”)

and

skarn

alteration

at

the

newly

identified

Hook

target

on

its

100%

owned

Hercules

Property

in

western

Idaho

(the

“

Property

”).

The

alteration

style

identified

at

Hook

is

consistent

with

the

edges

of

other

porphyry

copper

systems

on

the

Property

and

aligns

with

the

results

of

recently

completed

geophysical

surveys,

including

Hook’s

large,

near-surface

chargeability

anomaly,

occurring

approximately

3

km

east

of

the

Company’s

Leviathan

porphyry

copper

system.

The

Hook

target

is

centered

on

a

large,

near-surface

chargeability

anomaly,

however

the

nearest

available

drill

pad

under

the

Company’s

existing

permit

was

located

on

an

established

road

approximately

400

meters

west

of

the

anomaly.

Rather

than

immediately

permit

new

road

access

to

the

target,

the

Company

elected

to

first

use

the

existing

permitted

drill

pad

to

establish

geological

support

for

the

target.

Core

logging

of

HER-26-03

has

now

indicated

support

for

advancing

such

additional

permitting

and

road

construction.

Figure

and

(right)

IP

chargeability

anomalies

on

the

Hercules

Property

and

the

drilled

location

of

HER-26-03.

Chargeability

is

clipped

to

>17

mV/V.

HER-26-03

began

in

relatively

unaltered

rock

outside

of

the

anomaly

which

transitioned

to

increasing

phyllic

alteration,

with

strong

pyrite

ranging

from

5-10%,

as

disseminations

and

porphyry-style

3

“D-veins”.

Importantly,

the

alteration

appears

consistent

with

the

pyrite

halo

surrounding

the

Company’s

nearby

Leviathan

porphyry

copper

system.

Unlike

at

the

Leviathan

target,

HER-26-03

did

not

have

to

drill

through

younger

post-mineral

cover

and

was

drilled

entirely

within

Triassic-age

geology,

which

hosts

the

Late

Triassic

porphyry

copper

mineralization

on

the

Property.

The

hole

intersected

volcanic

and

carbonate-bearing

sedimentary

lithologies

consistent

with

the

lower

portion

of

the

Triassic

stratigraphy

mapped

throughout

the

Hercules

district.

This

lower

stratigraphic

sequence

includes

iron-

and

carbonate-rich

host

rocks

that

are

considered

favourable

for

the

development

of

skarn

and

associated

copper

mineralization

in

porphyry

systems.

Assays

are

pending;

however,

given

the

distal

nature

of

the

intercept

within

the

interpreted

pyrite

halo,

the

results

are

expected

to

be

more

useful

for

providing

additional

vectoring

information

toward

the

system

than

for

returning

significant

copper-molybdenum

intercepts.

Drilling

efforts

will

move

northeast

toward

the

high-chargeability

core

at

the

Hook

anomaly

targeting

a

potential

causative

porphyry

intrusion,

which

may

host

a

shell

of

copper-molybdenum

mineralization,

akin

to

that

observed

at

the

Leviathan

porphyry

system.

at

the

similar

chargeability

response

at

both

targets.

George

Ogilvie,

President

and

Chief

Executive

Officer,

commented

:

“The

team

utilized

existing

road

infrastructure

to

provide

an

efficient

initial

test

of

the

newly

identified

IP/MT

geophysical

anomaly

at

Hook,

without

incurring

the

permitting

costs

and

associated

delays

that

would

have

been

required

for

new

drill

access.

This

initial

drill

test

has

provided

encouraging

geological

indications

of

potential

4

porphyry-related

alteration,

supporting

the

strategy

to

continue

testing

the

high-strength

core

of

the

anomaly

along

its

strike

extent.

He

continued,

“Looking

forward,

continued

drilling

will

focus

on

expanding

our

near-surface

targets,

particularly

at

Leviathan,

where

more

than

30,000

m

of

combined

drilling

has

tested

both

the

at-surface

epithermal

silver

mineralization

and

the

underlying

copper

porphyry

system.

In

addition,

initial

drilling

in

HER-26-03

has

upgraded

Hook

to

a

particularly

compelling

near-surface

target,

supported

by

geological

and

geophysical

similarities

to

Leviathan.

These

results

warrant

an

updated

plan

of

operations

to

facilitate

the

next

phase

of

follow-up

drilling,

targeted

to

commence

in

2027.”

diamond

drills

active

at

Hercules

property.

Both

drills

are

conducting

step

outs

(HER-26-05

and

of

the

Leviathan

with

a

focus

on

expanding

hangingwall

and

footwall

mineralization

along

strike

and

to

depth,

in

an

area

with

a

gap

in

drilling

between

Leviathan

and
