NEW YELLOW PEAK CLAIMS STAKED

EVIDENCE FOR PORPYHRY POTENTIAL

 

Great Western Mining Corporation PLC (AIM - GWMO, Euronext Growth - 8GW),
which is exploring and developing gold, silver and copper targets in the
Walker Lane belt of Nevada, USA, announces the staking of a new group of 20
claims at Yellow Peak in the northeastern end of the Little Huntoon Valley.

 

HIGHLIGHTS

 

·    Twenty new claims staked at Yellow Peak close to and on trend with
the Huntoon Copper Project.

·    Significant outcropping phyllic alteration identified which is a key
indicator of porphyry-style mineralisation.

·    Highly evolved granite phase identified through fieldwork, previously
unrecognised in the region and strengthening evidence for a large-scale
magmatic-hydrothermal system.

 

Great Western Chairman Brian Hall commented:  "We are very pleased to have
secured the rights to the Yellow Peak area which we believe will add
significant value to the Huntoon Copper Project. The identification of
previously unrecognised granites at Yellow Peak reinforces our belief that
this region has the potential to host a substantial porphyry copper system and
we will start work in earnest on these new claims, aiming to unlock value for
shareholders.

 

In a complex and rapidly changing environment, domestic resources of copper in
the U.S.A., already categorised as a critical metal, will become a more and
more interesting commodity and we are well placed to move the Huntoon Copper
Project forward.  We will provide updates as exploration progresses."

 

YELLOW PEAK

 

Twenty new claims have been staked at Yellow Peak, situated close to the
Company's established Huntoon Copper Project in Mineral County, Nevada. The
decision to stake Yellow Peak was driven by the identification of extensive
outcropping phyllic alteration, a recognised indicator of porphyry copper
mineralisation, and the presence of a key highly evolved granite phase that
has never previously been recorded in this region.

 

The phyllic alteration at Yellow Peak is characterised by
quartz-sericite-pyrite assemblages across multiple exposures, indicative of
high-level hydrothermal fluid alteration. Such features are commonly
associated with shallow portions of porphyry copper systems and enhance the
geological prospectivity of the area.

 

In addition, Great Western's technical team has identified a distinct, highly
evolved granite phase within the Yellow Peak area, which likely correlates
with the Crowne Point granite mapped by the Company at the centre of the West
Huntoon copper prospect. This granite is geochemically distinct from other
intrusive phases in the region and is typically associated with late-stage
magmatic processes that can be linked to porphyry copper mineralisation.
Identification of this phase is original work by Great Western and its
independent porphyry consultant, Dr. Lawrence Carter.  It is now understood
to be associated with alteration and mineralisation over a number of sites
over Great Western's claims in the northeastern end of the Huntoon and Little
Huntoon Valleys.

 

The staking of the Yellow Peak area aligns with Great Western Mining's broader
exploration model for the Huntoon Copper Project, where multiple lines of
evidence continue to support the presence of a large-scale
magmatic-hydrothermal system. Planned follow-up exploration, including
detailed mapping, sampling, and geophysical surveying will investigate the
area's potential.

Notes to Editors

The Company has a large tract of acreage in Mineral County, Nevada. The area
consists of rugged, mountainous terrain, which means that large parts of it
remain under-explored. Mineral potential is hosted by the regional Walker Lane
Structural Belt, the largest structural and metallogenic belt in Nevada, yet
one of the least explored in recent times, with gold, silver and copper
currently produced in Mineral County.  Great Western has seven distinct
concession areas which offer the potential for exploiting (1) short term gold
and silver deposits and (2) long-term, world-class copper deposits.

Six of the Company's properties are in the west of Mineral County and the
seventh and most recent acquisition, the Olympic Gold Project, is in the east
of the county, some 50 miles from the main group.  All the Company's claims
are 100% owned. Claims at the Eastside Mine Group have been contributed to a
pooling agreement with Bronco Creek Exploration, Inc. and in addition the
Company participates in the Huntoon Mine Area Cooperation Agreement with
landowner-neighbour Crowne Point Resources with whom it shares resources.
Great Western's small exploration team is supported by locally based
consultants and contractors.

The state of Nevada is one of the world's most mining friendly
jurisdictions.  While tightly regulated and environmentally conscious, Nevada
welcomes the mining industry.  Great Western takes care to ensure that its
claims are maintained in good standing and all regulations observed.

There are numerous gold and silver prospects on the Company's acreage,
including extensive historic mine workings which offer the opportunity for
secondary recovery. The Company is party to a 50-50 joint venture known as
Western Milling LLC which is constructing a mill to process pre-mined material
for secondary recovery of gold and silver.

Furthermore, through extensive drilling over a five-year period, GWM has
established a Mineral Resource on its first target area known as M2, of 4.3
million tonnes at 0.45% copper, for 19,000 tonnes of contained copper metal.
This resource has been independently reported in accordance with JORC
guidelines.

GWM has also established an Inferred Resource Estimate of 31,000 tonnes
grading 1.6 g/t gold and 3.0 g/t silver in tailings associated with the OMCO
Mine at the Olympic Gold Project.  Additionally, exploration targets have
been independently reported as follows:

·    3,400 - 6,400 tonnes grading between 0.5 and 1.2 g/t Au and 1.2 and
2.1 g/t Ag in the substrate beneath the tailings volume at the Olympic Mine.

·    9,000 - 12,000 tonnes grading between 0.9 and 2.4 g/t Au and 2.0 and
5.1 g/t Ag in a coarse stockpile at Olympic Mine.

·    4,200 - 7,700 tonnes grading between 40 and 140 g/t Ag and 0.3 and
0.3 g/t Au in spoil heaps at Mineral Jackpot.
