Tungsten Exploration Programme Planning & Live Investor Presentation

 

Accelerating the Defender Tungsten Project in Nevada Towards a Maiden MRE

 

Great Western Mining Corporation PLC, a strategic minerals exploration and
development company, is pleased to update investors on its upcoming
exploration plans at the Defender-Pine Crow Tungsten Project ("Defender" or
the "Project") in Mineral County, Nevada USA. This follows the receipt of
highly encouraging assay results at Defender announced in January 2026.

 

Highlights

·    Accelerating exploration activity with the objective of defining a
maiden Mineral Resource Estimate ("MRE") in Q4 2026.

·    Assessing a 3 km long mineralised trend between Defender and the
Company's existing MRE at M2, as shown in Figure 1 below, through detailed
mapping and geophysical surveys commencing in March.

·    Commencing groundwork in April to prepare drill pads, ahead of the
planned start of drilling in June.

·    Anticipating additional assay results from new channel cuts in Q2.

 

Great Western Chairman Brian Hall commented: "Defender is shaping up to have
the potential to become a tungsten discovery of considerable scale and
significance. Its geological setting, noting its proximity to Guardian Metals'
Pilot Mountain Project approximately 30 miles away, reinforces our confidence
that we are operating within a highly prospective polymetallic district.

 

"We have designed the upcoming exploration programme to accelerate progress
toward a maiden MRE, which we see as a key catalyst in unlocking value at
Defender and across our broader portfolio. Importantly, Defender appears to
represent the far eastern extension of a mineralised trend that includes our
M2 resource, located more than 3 km to the southwest, highlighting the
potential continuity and district-scale opportunity.

 

"This is clearly an underexplored area with substantial upside and we are
eager to commence systematic work to define the full scale of the mineralised
system."

 

DETAILS

Background

The Defender and Pine Crow tungsten skarns are located approximately 3 km
northeast of and on trend with the Company's M2 skarn copper resource.
Historic production of tungsten from these skarns dates back to a short spell
of extraction towards the end of the Second World War.

 

Following earlier positive field mapping and grab sampling, in December 2025
the Company undertook a machine-cut channel sampling programme at Defender.
Two channels returned significant tungsten mineralisation, including 6 m at
0.17% WO₃, including 1 m at 0.43% WO₃, and 16 m at 0.30% WO₃, including
2 m at 0.66% WO₃ (see RNS dated 29 January 2026). Importantly, elements that
could represent potential processing penalties were recorded at very low
concentrations, and silver mineralisation was also intersected within Channel
B.

 

2026 Exploration Programme

Following a successful fundraise completed in January 2026, the Company is
fully funded to execute an expanded exploration programme at Defender during
2026. Accordingly, the Company has designed a programme to accelerate progress
towards defining a maiden MRE, targeted for Q4 2026, and to test the scale,
continuity and geometry of the mineralised system at Defender, including its
potential relationship to the broader mineralised trend extending towards M2,
located more than 3 km to the southwest.

 

Detailed geological mapping and geophysical surveys will commence in March
2026 to assess the mineralised trend between Defender and the Company's
existing MRE at M2, as shown in Figure 1. This work is intended to refine the
geological model and support drill targeting initially at the eastern end of
the trend. Groundworks are scheduled to begin in April to prepare the drill
pads, ahead of the commencement of drilling. Bids from drilling contractors
are currently being sought for the programme, with the objective of starting
drilling in June 2026.  In parallel, additional assay results from newly
completed channel cuts are expected in Q2 2026 and will be incorporated into
the exploration model.
