Tungsten Mining & Processing Strategic Partnership dated 08

8 July 2026
Guardian Metal Resources plc
('Guardian Metal' or the 'Company')
Strategic Partnership Signed to Advance Domestic Tungsten Mining
and Processing for U.S. Defense Applications
Guardian Metal Resources plc (NYSE.A: GMTL, LON: GMET, OTCQB:
GMTLF), a strategic exploration company focused on tungsten in
Nevada, USA, is pleased to announce that it has entered into a
strategic partnership (the "Partnership") with the Montana Mining
Association ("MMA") to collaborate on a tungsten mining and
recovery pilot program supporting domestic defense applications.
The Partnership is also being advanced in conjunction with Montana
Technological University ("MTU") and the Army Research Laboratory
("ARL").
As part of the Partnership, Guardian Metal will supply stockpiled
legacy ore from its Tempiute Tungsten project ("Tempiute" or the
"Project"), located near Rachel, Nevada, approximately 150 miles
northeast of Las Vegas. 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.
As a critical defense metal, tungsten has been formally designated
a strategic priority by the U.S. government. Guardian Metal's
mission is to advance its co-flagship projects, Tempiute and Pilot
Mountain, as a cornerstone of U.S. tungsten supply, directly
supporting national efforts to reshore production. This strategy is
expected to reduce reliance on foreign supply chains, strengthen
economic and defense security, and deliver long-term value for
shareholders.
KEY HIGHLIGHTS
|
●
|
Guardian Metal has entered into the Partnership to advance an
entirely U.S.-based tungsten mining and recovery pilot program to
support domestic defense applications.
|
|
●
|
Tempiute selected as a U.S. feedstock source, with an initial
~250-400 tonnes of stockpiled legacy ore to be transported from
Tempiute to Philipsburg, Montana, for trial processing at the
partner milling and processing facility.
|
|
●
|
First shipments of legacy ore are expected by late summer 2026,
subject to completion of metallurgical test work currently underway
at partner laboratories in both the U.S. and U.K., and pilot-scale
test work to be completed on-site in Montana.
|
|
●
|
The program is focused on upscaling domestic tungsten-rich sources
of historical mine tailings and legacy ore stockpiles to evaluate
pathways toward commercial production of tungsten metal powder for
defense-relevant applications within the U.S.
|
|
●
|
The Partnership further validates Guardian Metal's strategy of
advancing its co-flagship tungsten assets, Tempiute and Pilot
Mountain, towards a fully domestic mine-to-market tungsten supply
chain.
|
|
●
|
If the initial program is successful, further shipments of
tungsten-rich material from Tempiute could be supplied as part of
an expanded program.

Matt Vincent, Executive Director of MMA,
commented:
"We are excited to work with Guardian Metal on this Partnership,
which we feel is incredibly important to the industry and our
nation's security. Guardian Metal's Tempiute material represents
what we believe will prove to be an important domestic source of
tungsten for this Partnership, as well as a demonstration of our
Association's ability to effectively establish a broader network of
critical minerals projects across the Mountain West."
Oliver Friesen, CEO of Guardian Metal Resources,
commented:
"We are delighted to enter into this Partnership with MMA, ARL, and
MTU to advance this strategically important pilot program. The
selection of Tempiute as a feedstock source is a strong endorsement
of the strategic significance of Guardian Metal's entirely
Nevada-based tungsten project portfolio.
"At
a time when tungsten supply security has never been more critical
to U.S. defense and industrial capability, this initiative
represents a tangible step toward building an entirely domestic
supply chain, free from reliance on foreign sources."

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
US$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.
