NEW CLAIMS STAKED FOR TUNGSTEN

 

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 three tungsten targets over both
newly staked and existing claims in Mineral County, Nevada.

 

Highlights

·    Six new claim blocks staked to cover Pine Crow and Defender tungsten
workings

·    Previous grab highlights from these claims of 2,590, 2,430 and 1,600
ppm tungsten

·    Separate area of prospectivity identified 9 km to the southwest

 

Great Western Chairman Brian Hall commented: "Our extensive claims in the
Walker Lane Belt of Nevada are rich in many minerals.  Over the last two
years we have reacted to copper being designated a critical mineral in the
USA, revisited our copper prospects and have reported, with independent
verification, the possibility of a copper play on a far larger scale than the
resource we have already established through drilling in the same area.

 

"Tungsten has also been officially designated a critical mineral in the USA
and in light of this we have revisited known areas of elevated tungsten which
were highlighted during our recent exploration programmes. Having thoroughly
reviewed all the data for tungsten on our claims, both historical and recent,
there is strong evidence of the metal in two separate claim areas.  To move
this forward, in recent days we have staked and registered six new claims
contiguous to our existing claims and encapsulating two old tungsten mines.
We will be working on the data further over the winter months and planning a
programme of works for the 2025 season."

 

Introduction

In the light of recent political developments which emphasise the need for new
domestic tungsten resources in the United States, Great Western has undertaken
a review of the tungsten prospectivity on and adjoining its existing claims,
with positive results.  Tungsten is included on the list of critical minerals
as determined by the US Department of the Interior, while copper is identified
as a critical material for energy by the US Department of Energy.

 

Two separate former tungsten workings historically known as Pine Crow and
Defender, sit close to the northern edge of Great Western's Black Mountain
claims (Figures 1 & 2). In recent days the Company has staked and
registered six new claims which cover both Pine Crow and Defender.

 

Separately, a 600 m long east-west tungsten-in-soils anomaly is evident in the
southern part of the Company's Jack Springs claim group, approximately 9 km to
the southwest of the workings described above (Figure 1 & 3). This anomaly
is parallel to and overlies a linear magnetic high.

 

Pine Crow and Defender

The Pine Crow and Defender mines include surface workings on mineralised
features, each having around five (5) acres of dozer scrapes and small pits
focused on veins and altered outcrops. These features were selectively grab
sampled during reconnaissance work undertaken by the Company in 2018.
Highlights are as follows (Figure 2):

·    Pine Crow, three samples from mine dumps - 2,590, 2,430 and 1,520 ppm
tungsten.

·    Defender, two samples from outcropping veins and altered host rock -
1,600 and 850 ppm tungsten.

·    A sample from the trend between the two workings, on existing GWM
claims identified altered host rock - 210 ppm tungsten.

 

The samples from Pine Crow are also enriched in molybdenum, with values of
700, 690 and 590 ppm. A grab sample data table is available in Appendix A.

 

Jack Springs Tungsten

Existing reconnaissance soil sampling over the northern parts of the Jack
Springs claim group shows a 600 m long (east-west) and 100-150 m wide
(north-south) zone of samples (Figure 3) anomalous for tungsten. The anomaly
occurs on six adjacent soils lines (line spacing 100 m, sample spacing 50 m)
collected during 2012 and consists of between one and three samples above 70
ppm tungsten on each line. The maximum value detected was 96.3 ppm tungsten.

 

The soil anomaly correlates with a roughly linear east-west trending magnetic
anomaly which was detected on GWM's drone magnetometry carried out in early
2021. The juxtaposition of elevated tungsten with a magnetic anomaly is
suggestive of a skarn setting. As the tungsten-in-soils anomaly is obscured to
the east by tertiary volcanic cover, there is potential to extend the area of
exploration.

 

Next Steps

Further soil sampling and field mapping is planned at both areas of tungsten
prospectivity. If the results of this work are positive, geophysical surveys
will be designed to develop drill targets.

ADDITIONAL INFORMATION

 

Results presented in this report pertain to previous phases of work by Great
Western, results from which have been previously announced for other elements.

 

All soil samples were submitted to Florin Laboratory, Reno, Nevada, in 2012.
Soil samples were screened to -80 mesh and analysed by method 7045; aqua regia
digest with ICP finish for a 22-element suite. Quality control samples were
inserted by the company are understood to have been satisfactory.

 

Grab samples were submitted to Bureau Veritas Laboratory (then known as
Inspectorate America Corporation), Reno, Nevada in 2018, analysed by method
Au-FA30 for gold (30 g fire assay, with gravimetric finish for overlimit
samples) AQ370 for a 24-element suite via aqua regia digest and ICP-ES.
Samples were submitted in various small batches and lab internal QC protocols
deemed to be sufficient for these results.

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.
