HIGH GRADE SAMPLE RESULTS AT WEST HUNTOON

 

Great Western Mining Corporation PLC (AIM: GWMO), which is exploring multiple
precious and base metal prospects in Mineral County, Nevada, is pleased to
announce the results of surface sampling at West Huntoon during spring 2025.

 

HIGHLIGHTS

 

·    1.07 g/t gold and 455 g/t silver from a sample at the Crowne Pointe
granite extends a high-grade trend there to an 80 m strike length.

·    A sample located in the far north of the Crowne Pointe granite
outcrop returned 2.16 g/t gold, 34.2 g/t silver and 1.58% copper.

·    Multiple samples in the range 0.1 - 0.2 g/t gold and 5-20 g/t silver.

·    Seven samples around the Crowne Pointe granite outcrop contain copper
grades of 0.18 - 0.31% copper, with an outlier at 0.68% copper.

·    A single grab taken to the northwest of previous sampling contains
0.44% copper and 6.4 g/t silver.

·    A single grab taken to the northeast of the granite outcrop area
contains 56 g/t silver and 6.34% zinc.

 

Great Western Chairman Brian Hall commented: "The West Huntoon area has the
potential to be a major copper project as well as having an abundance of
precious metal and other mineral indications. It is looking more and more
exciting as we continue our field work and expand the mineralisation
footprint.

 

"We are currently preparing a summer drill programme which will include the
Rhyolite Dome gold prospect on the Olympic Gold Project as well as several
targets at West Huntoon.  In the same general area as West Huntoon, later
this month we will have a team in the field sampling surface tungsten
indications around and between the Defender and Pine Crow tungsten workings.
We will keep shareholders informed as we make progress."

 

BACKGROUND

 

West Huntoon is a group of claims on high ground to the west of the flat
Huntoon Valley.  In the hills on the other side of the valley is the M2
project where the Company has extensively drilled and already established an
inferred copper resource.  Directly south of M2 is the M4 prospect which the
Company has also drilled and found positive indications of copper.  Due to
sedimentary cover, there are no surface indications of mineralisation on the
floor of the valley and in due course this is likely be drilled, in an attempt
to establish connectivity right across the valley.  West Huntoon and M2 are
approximately 12 km apart which indicates the potential size of the copper
prospect if connectivity can be established. The greater area has been
designated the Huntoon Copper Project.

 

West Huntoon includes an abandoned gold mine (the Huntoon Mine) and in 2017
Great Western drilled a single scoping hole close to this mine, based on
limited information, which recorded measurable grades of both gold and
copper.  Commencing in late 2023, the company launched a new initiative at
West Huntoon, discovered a previously unknown outcrop of granite, commissioned
a report on this granite which verifies the setting for a potential copper
porphyry, carried out extensive soil sampling and also commissioned a
geophysical (IP) survey which indicates continuity of copper where
mineralisation disappears from sight under the valley floor sediments.

 

During the current quarter, Great Western will be drilling on the high ground
at West Huntoon with an initial programme of 5 holes, each likely to be
approximately 200 m in length, (1) aiming to establish that the consistent
copper showings at surface across a large area are matched at depth and (2) to
continue exploring the precious metals potential.  The survey results below,
acquired in collaboration with a team from the UK's Camborne School of Mines,
analyse precious metals and other minerals found to be present in this complex
and highly mineralised area.

 

WORK PROGRAMME

 

Great Western conducted a selective surface sampling programme at West Huntoon
earlier this year, focused on potentially mineralised ground in the Crowne
Pointe granite area, to which it holds rights under the previously announced
Huntoon Mine Cooperation Agreement. This work was a follow-up to an earlier
programme which recorded exceptionally high grades of silver and gold of up to
2,438 g/t Ag and 5.14 g/t Au. Other samples from around the wider area were
taken as part of a field consultation and the academic collaboration with the
Camborne School of Mines.

 

NOTABLE RESULTS

 

·    A very high silver grade of 455 g/t Ag together with elevated gold of
1.07 g/t Au from a sample taken in the southern parts of the Crowne Pointe
granite. Previous samples from this area included one with 2,438 g/t Ag &
5.53 g/t Au, situated 40 m to the southwest, and one with 102 g/t Ag &
4.51 g/t Au, taken a further 40 m to the southwest. These three samples
together form an 80 m trend.

·    A first sample from the far northern end of the Crowne Pointe granite
returned 2.16 g/t gold, 34.2 g/t silver and 1.58% copper, showing that
potential for an elevated precious metals zone occurs at a considerable
distance from the established zone in the southeastern portion.

·    Multiple samples with elevated gold and silver values (0.1-0.2 g/t Au
and 5-20 g/t Ag), mainly located adjacent to the high-grade samples in the
southern tip of the Crowne Pointe granite.

·    Widespread copper anomalism in the Crowne Point granite, with seven
samples in the range 0.18 - 0.31% Cu, and an outlier at 0.68% Cu. These
samples were selected from local surface showings of copper oxide
mineralisation.

·    Outside the granite area, a grab sample taken 180 m to the northwest
of the nearest previous sample, from a local copper sulphide and oxide showing
associated with a 1 m wide vein, returned 0.44% copper and 6.4 g/t silver.
This sample again expands the prospectivity of the West Huntoon area.

·    Also outside the granite area, 45 m upslope from the western margin
of the Crowne Pointe granite, a sample from a breccia zone contained 56 g/t
silver, 6.34% zinc, 0.51% Pb and 0.09% Cu.

 

These new results significantly expand the known footprint of mineralisation
at West Huntoon, both within the Crowne Pointe granite area and in the
surrounding host rocks. The repeated occurrence of high-grade silver and gold
values along an emerging trend in the south of the Crowne Pointe granite, the
identification of precious and base metal potential at the granite's northern
extent and the presence of copper and polymetallic mineralisation outside the
granite all point to a larger, more complex mineralising system than has
previously been recognised. These findings will guide future exploration
targeting.

ADDITIONAL INFORMATION

 

All grab samples were analysed at Paragon Geochemical Laboratories, Reno,
Nevada. A quality control standard sample was included in the batch by the
company and results of this reviewed prior to release. Grab samples were
analysed by method Au-FA30/AuAg-GR30 for gold (30 g fire assay, with
gravimetric finish for overlimit samples) 35AR-OES for a 35-element suite via
aqua regia digest and ICP-OES. The gold grade in the QC sample was within
acceptable limits. Both the silver and copper grades were below three standard
deviations from the expected value, indicating that results reported here are
likely conservative.

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.
