Tempiute Historical Mine Tailings
Update dated 13 May, 2026.

Guardian Metal Resources PLC
('Guardian Metal' or the 'Company')
Tempiute Tungsten Project Historical Mine Tailings
Update
Guardian Metal Resources PLC (NYSE.A:GMTL,
LON:GMET, OTCQB:GMTLF), a strategic mineral
exploration company focused on tungsten in Nevada, USA, is pleased
to announce an update relating to historical mine tailings present
at the Company's Tempiute Tungsten Project
("Tempiute" or the "Project") located in south-central Nevada less
than 250 miles (402 km) southeast of the Company's Pilot Mountain
Tungsten Project. Tempiute, formerly known as the Emerson Tungsten
Mine, is a significant past producing tungsten mine, which was
originally discovered in 1916 and most recently operated during the
1980s. The Company is evaluating near-term resource and tungsten
production opportunities across the extensive former producing
mine, with the identification of tailings from decades of
historical production adding a compelling new dimension to the
Project.
As a critical defense metal, tungsten has been designated as a
strategic priority by the U.S. government. Guardian Metal's mission
is to establish its co-flagship tungsten projects as the
cornerstone of U.S. mined tungsten supply, directly supporting
national efforts to re-establish domestic production. This is
intended to help the U.S. reduce reliance on foreign supply chains,
strengthen economic and defense security, and deliver long-term
value for shareholders.
Oliver Friesen, CEO of Guardian Metal,
commented:
"Tempiute has a long and well-documented tungsten production
history, and we believe the historical tailings represent a unique
opportunity warranting further investigation, one that could
provide near-term support to the U.S. tungsten supply chain
alongside a meaningful reclamation outcome. Our initial assessment
has confirmed the presence of tungsten across a substantial surface
footprint. As a result we are advancing towards an auger drilling
program which will help us better understand the characteristics of
the material subsurface.
"With tungsten recognised as a critical defense metal and domestic
supply a priority for the U.S. government, this work is very
timely. Furthermore we are encouraged by the results of our
investigations to date."
HIGHLIGHTS
|
●
|
Guardian Metal is evaluating the potential of recovering tungsten
and other metals from the historic tailings at Tempiute, with a
view to provide an opportunity for near-term, domestically sourced
tungsten in the U.S.
|
|
●
|
Through detailed mapping and sampling, the surface area footprint
of historical tungsten-enriched mine tailings at Tempiute (the
"Tempiute Tailings") has been determined to cover approximately 550
acres (2.23 km²).
|
|
●
|
As a result, Guardian Metal has expanded its mineral rights
position significantly, staking 193 claims and increasing its
overall Tempiute footprint by over 375% to secure what the Company
strongly believes to be the full extent of the Tempiute Tailings.
This expansion runs parallel to the Company's appropriate
environmental inquiry.
|
|
●
|
An auger drilling program is planned to commence in June 2026,
subject to receipt of required permits, and will enable
characterization of the tailings material and surrounding soils for
environmental evaluation and assessment of the tungsten resource
potential.
|
|
●
|
The combination of modern recovery methods and elevated tungsten
prices makes this an increasingly compelling near-term domestic
tungsten supply opportunity, while also offering a meaningful
reclamation outcome.
|
|
●
|
Previously milled material sitting at surface, combined with
existing on-site infrastructure, means the cost and development
timeline of a reprocessing operation could compare favourably to a
conventional tungsten mining project, subject to confirmation of
sufficient tailings tonnage and grade.
|
Background
To determine the economic and environmental remediation potential
of historical mine tailings at Tempiute, the Company undertook a
detailed mapping and sampling program across the entire historical
mine tailings area.
Evaluation of publicly available production records, dating back to
the 1930s, was correlated with satellite imagery, spectral
analysis, and ground mapping to identify the tailings footprint
extending down slope from the Tempiute mine. Follow up ground
investigation and surface sampling delineated a large
tungsten-enriched zone and confirmed the extent of the historical
mine tailings area to cover a surface footprint of approximately
550 acres (2.23 km²). Sampling also provided an initial
characterisation of the material, verifying the presence of
tungsten and other metals.
As a result, Guardian Metal expanded its mineral rights position
significantly, staking 193 mining claims and increasing the overall
Tempiute Project footprint by over 375%, to secure what the Company
believes to be the full extent of the historical
tailings.
Subject to receipt of the required permits, an auger drilling
program is planned to commence in June 2026 to characterise the
tailings material and surrounding soils for environmental
evaluation and resource potential. This work will advance the
Company's environmental inquiry and enable determination of the
potential for a tungsten resource.
Next Steps
The Company has submitted a Notice to the Bureau of Land Management
and the Nevada Division of Environmental Protection for the
proposed auger drilling program. Subject to approval, the auger
drilling program is targeted to commence in June 2026 and is
expected to take approximately three months to complete. The
program is designed to allow the Company to make all appropriate
inquiries regarding current environmental conditions on site, while
estimating the total volume and grade of tungsten and
base/precious-metal bearing material present.
In parallel, an independent metallurgical study will be completed
to determine the most effective method of recovering tungsten and
other metals from the tailings, with results expected in the coming
months. This study will also characterize the geochemistry of the
tailings post tungsten recovery to inform the final reclamation
design of the site.

About Guardian Metal
Resources
Guardian Metal Resources PLC (NYSE.A: GMTL, LON:GMET, OTCQB:GMTLF)
is a strategic mineral exploration company driving the revival of
U.S. mined tungsten production and strengthening America's defense
metal independence. The Company is advancing two co-flagship
tungsten projects, Pilot Mountain, one of the largest undeveloped
tungsten deposits in the U.S. and Tempiute, formerly America's
largest producing tungsten operation, both located in
Nevada, one of the top-rated mining jurisdictions in the
United States.
In July 2025, the U.S. Department of War (DoW) under Title III of
the Defense Production Act of 1950, as amended, invested
U.S. $6.2M in Golden Metal Resources (USA) LLC,
a wholly-owned subsidiary of Guardian Metal Resources
PLC, to support the Pilot Mountain PFS. The Company completed a
U.S. listing on the NYSE American on March 20,
2026.
Tungsten is a strategic metal critical to the defense, energy
transition, technology, and industrial sectors. In the context of
shifting geopolitical dynamics and tightening Chinese export
restrictions, Guardian Metal is well positioned to play a leading
role in re-establishing a secure, domestically mined U.S. supply
chain for this vital defense metal.
