DRILLING COMPLETED AT MINERAL JACKPOT
Great Western announces the completion of its drilling programme
at the Mineral Jackpot group of claims in Mineral County,
-- Four holes totalling 536 metres drilled in the Mineral Jackpot main workings area
-- All four holes drilled towards known, previously worked mineralisation.
-- All holes intercepted zones of target-type alteration.
-- Cuttings being sent to laboratory for assay
-- Summer 2022 drill programme complete and rig stood down
After short delays on account of severe storms in the area,
Great Western has now completed the first ever drill programme over
the Mineral Jackpot claims, made possible by the Company's upgrade
of a 14 km mountain mule track to a road earlier in the year. Great
Western was originally formed to exploit this area of historic gold
and silver mines, comprising the Silver Moon, Silver Bell, Ming
Toy, Bass and Mineral Jackpot mines, sometimes also collectively
known as 'Cabin Rock'. Rock chip, soil and grab samples have been
assembled and analysed over the last three years and magnetometer
surveys conducted, together indicating potential for a doubling of
the known mineralisation over the claims, as previously reported.
Mineral Jackpot is also host to numerous spoil heaps from historic
mining operations, which the Company is planning to load from site
using the new road and then process for secondary recovery of
Great Western chairman Brian Hall commented: "This completes an
exciting summer drill programme over four of the Company's many
prospect areas, the Southern Alteration Zone (Rock House Group),
Trafalgar Hill (Olympic Gold), OMCO Mine area (Olympic Gold) and
Mineral Jackpot (Black Mountain Group), with 24 holes drilled
totalling 2,798 metres drilled depth. We now await assay results
from busy independent laboratories, timing of which is outside our
control but which we will announce as soon as they become
Mineralisation at Mineral Jackpot consists of a series of quartz
veins and associated alteration zones, hosted in granite. These
veins strike to the northwest and dip at 40-50deg to the southwest.
Although most of the details of historic production have been lost,
the gold and silver workings were extensive and numerous
mineralised waste piles from the workings are distributed across
the hillsides. More recently, contemporary exploration techniques
have identified vein material from grab samples. These alteration
zones will now be modelled across the holes drilled by Great
Western, using the known structural orientation of the
Each of the four holes drilled intersected at least three zones
containing alteration of target type, some of which also exhibited
significant amounts of chips interpreted to be derived from quartz
veins. Other weaker alteration zones occurred within the holes
between the noted zones but are not detailed here.
The first hole from the lowermost pad at the main workings was
designed to test the ground directly beneath the portal developed
in 'Vein 01', the most historically worked of the veins. Vein 01 is
also the most north-easterly, being the lowest in the array, and
its footwall is largely unexplored. A secondary objective of all
the four initial holes was to test the granite beneath this
structure. The hole intersected alteration of target type directly
below the workings at 6 - 10 m. This is thought to be the down-dip
extension of Vein 01. Additional zones of interest with up to 50%
altered granite and milky quartz chips were identified at 59 - 64 m
and 94 - 98 m. Strong haematite alteration occurred within the
latter zone from 96 - 98 m. The hole finished at 152 m.
The second hole was drilled from the same pad as MJRC001, being
a steeper hole to test the down-dip continuity of zones identified
in the first hole. This hole also intersected alteration of target
type near the start of the hole at 15 - 18 m, possibly the
continuation of Vein 01. Another zone of strong alteration was
intersected at 67 - 70 m, and a third at 105 -114 m. The hole
finished at 128 m.
The third hole was drilled from 50 m northwest at the Main
Workings to test the along-strike continuity of zones identified in
the first two holes. A strong alteration zone with quartz vein
chips was identified from 10 - 15 m. Moderate to strong alteration
occurs at 45 - 53 m around a mafic dyke, and moderate alteration
zones were also seen at 70 - 82 m and 105 - 113 m. The hole
finished at 122 m.
The fourth hole was drilled from the upper parts of the main
workings, a further 60 m to the northwest of MJRC003, again
designed to test the strike continuity of intersected zones. A
strong alteration zone with quartz vein chips was identified from
4.5 - 11 m. Weak to moderate alteration occurs from 41 - 52 m.
Moderate alteration with haematite was identified from 59 - 67 m.
The hole finished at 133 m.
The rig has now been released.

Notes to Editors
The Company has a large acreage position 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 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.
