Tungsten Exploration Update

 

Advancing Exploration Across the Defender-M2 Mineralised Corridor in Nevada

 

Great Western Mining Corporation PLC, the exploration and development company
focused on mineral projects in Nevada, USA, is pleased to provide an
operational update on exploration activities at the Defender-Pine Crow
Tungsten Project ("Defender-Pine Crow" or the "Project") in Mineral County,
Nevada, USA.

 

OVERVIEW

·    Initial exploration work programmes have been completed across the 3
km corridor between Defender-Pine Crow and the existing M2 copper resource.

·    Programmes designed to support the planned July 2026 drilling
campaign and assess the broader extent of tungsten mineralisation within the
Black Mountain claim area.

·    Gravity geophysical survey completed by Zonge International covering
approximately 3 km by 500 m.

·    Geological mapping of skarn occurrences completed, and new grab
samples submitted for assay, identifying additional prospective zones and
structural controls.

·    Drill pad locations selected for upcoming drilling and access roads
between the historic workings known as the Dough God Mine, located
approximately 500m south-west of Defender, and the Defender Mine submitted to
the Bureau of Land Management ("BLM") for permitting approval.

·    Four new machine-cut trenches completed, with all samples submitted
for assay:

o  Three trenches located between Defender and Pine Crow Mine.

o  One trench completed at the historic workings known as the Widowmaker
Mine, located 2 km west of Defender along strike and midway between Pine Crow
Mine and the M2 copper resource.

 

Great Western CEO, Ed Loye, commented: "The completion of these programmes
marks another important step in accelerating the Defender-Pine Crow tungsten
project towards drilling and resource definition. In particular, the scale of
the geophysical and geological work completed across the broader mineralised
corridor is helping us better understand the continuity and district-scale
potential of the tungsten system.

 

"The addition of trenching at the historic workings known as the Widowmaker
Mine is especially encouraging as it extends exploration activity further west
along strike towards M2, supporting our view that this is part of a much
larger mineralised trend.

 

"With drilling scheduled to commence in July, we now look forward to the next
phase of work and to receiving the assay and metallurgical results in due
course."

 

DETAILS

The Company is undertaking a fully funded 2026 exploration programme to
deliver an initial maiden resource estimate for Defender-Pine Crow tungsten
project by end of Q4. The current work programme is designed both to support
the planned drilling campaign commencing in July 2026 and to further assess
the scale, continuity and geometry of tungsten mineralisation within the
broader Black Mountain claim area.

 

As part of this work, Zonge International has completed a detailed gravity
geophysical survey covering approximately 3 km by 500 m across the corridor.
The survey data will be integrated with recent geological mapping and grab
sampling as an additional vector to better understand the skarn and tungsten
mineralisation in the Defender to M2 corridor.

 

Preparatory work for drilling is also advancing, with proposed drill pad
locations and access roads between the Dough God Mine and Defender Mine now
selected and submitted to the BLM for permitting approval.

 

Additionally, four new machine-cut trenches have been completed across the
project area. Three pre-existing trenches and outcrops were machine cut
between the Defender and Pine Crow Mines, while a fourth was completed at the
Widowmaker Mine, located approximately 2 km west of Defender along strike and
midway between Pine Crow and the M2 copper resource. Samples from all trenches
have been submitted for assay, with results expected in due course.

 

As previously reported, the Company has also sent a 750 kg representative
metallurgical bulk sample to Eriez in Pennsylvania for flotation test work to
support future development studies.

exploration and development company focused on strategic minerals across
several 100%-owned claim groups in Mineral County, Nevada, a highly
prospective and mining-friendly jurisdiction. The Company has an increasing
strategic emphasis on tungsten as a critical mineral, while continuing to
advance its Huntoon Copper Project, which hosts a JORC-compliant resource of
4.3 Mt at 0.45% Cu with further porphyry upside. It also maintains exposure to
gold and silver through exploration and tailings reprocessing opportunities,
alongside evaluating farm-out and joint venture options to unlock wider
portfolio value.
