OLYMPIC GOLD DRILLING UPDATE

 

Great Western is pleased to provide the following update on its 2022 drilling
programme at the OMCO Mine area of the Olympic Gold Project in Mineral County,
Nevada where initial results exceed management expectations.

 

Following a three-hole drill project at the nearby Trafalgar Hill prospect,
announced by the Company on 13 June, the reverse circulation (RC) rig was
moved to the area of the former OMCO Mine, which produced gold at grades of
25-30 grams/ton and silver at 30 g/t until the 1940s.

 

HIGHLIGHTS

 

·    Ten holes totalling 1,339 metres drilled in the OMCO Mine area

o  Assays pending

·    Five of the holes were drilled over parts of the OMCO vein which had
been mapped as unmined but never previously drilled

·    The five holes intercepted quartz chip zones of 1-3 m thickness at
depths ranging from 25 to 45 m, consistent with the predicted thickness and
depth of the vein

·    The remaining five holes delivered visual indications of alteration
and veining

·    Four further very shallow holes drilled to evaluate a stockpile of
previously mined material for future processing

 

Great Western Chairman Brian Hall commented:   "The initial indications from
all these holes are very encouraging. By far the most significant development
is the apparent identification of unmined portions of the OMCO vein itself.
Should laboratory analysis establish grades of gold comparable to those
achieved from material mined in the past at the main OMCO vein, a shallow gold
resource could potentially be defined and expanded in short order, with
minimal additional work.  We cannot determine the timing of the assay results
as all the laboratories in the area are currently overworked but we will
update shareholders as soon as they are available."

 

 

SUMMARY

 

Below is a summary of the targets drilled and the resulting features of
interest:

 

·    Unmined portions of the main OMCO vein

Five holes, numbered OMRC015, 17, 21, 27 and 28 have now been drilled into
this target.  All five holes intersected evidence of quartz veining at depths
consistent with the predicted OMCO vein.  This part of the vein, discovered
in 1915 and mined during 1917-1921, historically averaged 25-30 g/t gold and
30 g/t silver recovered.  Maps prepared by previous lease holders identified
this area of 'unmined vein' to the southwest of the main workings, not drilled
until now.

·    Mined portions of the main OMCO vein

The OMCO vein workings are understood to be surrounded by a potentially
mineralised alteration zone. One hole, OMRC016, was drilled over the mined
portions of the OMCO vein to investigate this envelope, striking a mined void
from 24.5 - 27.5 m, with quartz vein chips and alteration in the 2-3 m above
and below this feature.

·    OMCO vein in host rhyolite, NW of the main workings

Hole OMRC018 investigated the possible presence of the main vein in this
vicinity.  Several zones of quartz chips were intercepted, with coarse
fragments and clay alteration from 15‑27 m, a depth which may correlate to
the OMCO vein.

·    OMCO vein, east

Hole OMRC019 was drilled directly to the east of the main OMCO vein on the
other side of a north-south fault, which had been the limit of previous mining
activity in the vein when operations ceased in the 1940s.   Quartz vein
chips were intersected at 128-144 m and 156-161 m around lithological
transitions.  In 2021, through magnetometry and drilling, Great Western
identified a low-grade gold anomaly east of the fault.  OMRC019 provides
further evidence of veining in this fault block, closer to the existing
workings and there will be follow-up work on this target in due course.

·    Far southeast target

Hole OMRC020 was targeted to follow up on drilling conducted in 2021 around a
magnetic anomaly which identified a weak but intensifying gold trend in the
far southeast of the zone.  Mild pyrite impregnation was identified from
113-273 m, with local 10-20 m zones of pyrite veinlets occurring within that
interval.

·    Mid Ridge

Hole OMRC026 was drilled directly west of the mine site on a north-south ridge
which features several silicified horizons at surface.  This ridge had not
previously been drilled. Silicification and some quartz vein chips occurred
between 24-32 m and another zone of quartz was encountered at 133-148 m,
possibly correlating to the OMCO and Lower Veins respectively.

·    Mineralised stockpile

In addition to the mineralised tailings pads at the OMCO Mine site which the
Company plans to exploit, there is a substantial stockpile of coarse mined
material near the headframe of the mine. Grab samples have confirmed that this
contains both mineralised and unmineralised clasts.  Four short holes
(OMRC022-25) have been drilled into this pile and six 20 kg bulk samples taken
from different locations on the surface and flanks.  Depending on assay
results, this stockpile may be treated for recovery of gold and silver through
the Company's proposed process plant.

 

Drill cuttings for all these holes in the OMCO Mine area are being assayed at
a laboratory, results of which will be announced when available.

 

The RC rig has now moved to the Mineral Jackpot target group, to undertake the
first holes ever drilled at those prospects.  This has been made possible
with a conventional drill rig following the Company's upgrade of the 14 km
mountain access road earlier this year.

Notes to Editors

The Company has a large acreage position in Mineral County, Nevada. Much of
the area consists of rugged, mountainous terrain, large parts of which are
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 are 100%
owned and operated.  The Company has an option to acquire a seventh property,
the Olympic Gold Project, in the east of the county.  Great Western's small
exploration team is supported by locally based consultants and contractors.

 

The state of Nevada is generally considered to be 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.

 

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.
