Non-Core Portfolio Tungsten-Focused Exploration Results

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 updates across its non-core Nevada-based project portfolio. Whilst the Company remains focused on advancing its co-flagship past-producing Pilot Mountain and Tempiute tungsten projects, exploration and claim staking has also continued across its wider, predominantly tungsten- and base-metal focused portfolio.

The Company's non-core project portfolio (the "Non-Core Assets") now comprises seven exploration-stage projects highly prospective for tungsten (W), gold (Au), silver (Ag), copper (Cu) and lithium (Li), which includes the following:

● White Elephant (W): Newly acquired by claim staking; strong tungsten channel sampling results achieved.

● Pilot North (W-Cu-Ag): Strategic location near to the Company's Pilot Mountain tungsten project now further enlarged by claim staking; strong tungsten, copper and silver channel and grab sample results achieved.

● Cinch (W-Ag): Newly acquired by claim staking; strong tungsten and silver grab sample results achieved.

● Garfield (Au-Ag-Cu): Enlarged by claim staking; strong gold, copper, silver results achieved.

● Golconda (Au).

● Stonewall (Ag-Au).

● Kibby Basin (Li).

The Company believes the now expanded Non-Core Asset base may hold considerable value. The Board is accordingly assessing various options for these assets, with the dual aims of ensuring they are advanced for the benefit of existing shareholders and allowing the Company to concentrate its resources on delivering its main objective: advancing the co-flagship Pilot Mountain and Tempiute tungsten projects towards commercial production. The Company will update the market as and when there are material developments.

Oliver Friesen, CEO of Guardian Metal, commented:

"Our generative exploration programme continues to demonstrate its value, with very strong tungsten, base- and precious-metal exploration results achieved across several of our Non-Core Assets and the identification and rapid claim staking of very exciting new tungsten projects including White Elephant and Cinch, both located in Nevada.

"It is remarkable testament to the hard work of the team for delivering this while also making fantastic progress across both of our co-flagship assets, Tempiute and Pilot Mountain. It highlights the breadth of our portfolio and the quality of our technical team.

"We believe these assets hold real potential, and we want to see them progress in a way that benefits our shareholders. We look forward to providing updates as we work to determine the best path forward for these assets."

Non-Core Portfolio Highlights:

FURTHER TECHNICAL INFORMATION

White Elephant Tungsten Project

The Company's exploration programme continues to generate tungsten skarn targets for further exploration. Following reconnaissance field assessment of the White Elephant target in late 2025, the Company staked a total of 57 BLM lode mining claims which now constitute the White Elephant Project. White Elephant is located in the historical Elk Mining District, near the Nevada-Idaho Line, in Elko County, Nevada, on Forest Service land.

The White Elephant project area encapsulates numerous historical tungsten, molybdenum, gold, silver and copper prospects, with the most notable being the historical Robinette claims, for which the Pyramid Tungsten, Inc., of Yakima, Washington, built a tungsten mill but was subsequently demolished in circa 1990.

After the initial reconnaissance and staking of White Elephant the Company undertook initial geological mapping and sampling across the project area. This initial appraisal field work has mapped and sampled numerous zones of scheelite and molybdenite bearing garnet-pyroxene skarn mineralisation, confirmed the location of historical mines, and noted evidence for historical exploration pits and trenches in several areas. Field mapping of two of the most prospective areas has identified several areas of outcropping skarn, which includes over 1,000 ft (300 m) strike length at the "Pyramid Zone". Several target areas have not yet been appraised in the field. During the initial field appraisal, the Company's geological team collected rock chip samples from outcrop across the Project area, and collected a total of 184 ft (56 m) worth of chip channel samples from 5 channels in the "Pyramid Zone", with results summarised in Tables 1 & 2 and Figures 1 & 2. Areas for follow up geophysical surveys and further detailed geological mapping were also highlighted, with the goal of generating robust drill ready targets.

Cinch Tungsten-Silver Project

Staking of the Cinch tungsten-silver project is another result of the Company's generative exploration programme. Following reconnaissance field assessment of the Cinch target in late 2025, the Company quickly acted to stake a total of 20 BLM lode mining claims to form the Cinch project. Cinch is located in North Lincoln County, Nevada, on BLM land, is accessible by maintained gravel road, and is 4 km from the paved Highway 93. Mineralisation styles include skarn and fault breccias, as well as sulphide bearing quartz veins. The project area encompasses several historical mine workings with evidence of historic exploration activity. Highlight grab samples collected during the reconnaissance visit are summarised in Table 3.

Garfield Gold-Silver-Copper Project

Building upon the positive results from induced polarisation (IP) geophysical surveys at Garfield announced in 20251, the Company contracted Dr Lawrence Carter to undertake further geological mapping and sampling at Garfield to test for possible outcropping extensions to the epithermal system. Geological mapping delineated further mineralised structures as well as an area of broader epithermal stockwork veining and mineralisation in highly silicified rhyolite. As a result, the Company quickly acted to stake 56 new BLM lode mining claims to acquire the new "Freeze South" and "Mother" zones (Figure 4). Highlight rock chip samples collected during the field campaign are summarised in Table 6 and Figure 4.

Whilst high-grade structurally controlled precious metal epithermal mineralisation remains the main target at Garfield, there also remains the potential for broader lower-grade but bulk tonnage mineralisation. As proof of concept, the Company took a 180 ft (54.9 m) chip channel sample across a broad zone of outcropping, intensely altered and oxidised rhyolite (kaolinite, goethite and hematite confirmed by TerraSpec VNIR-SWIR spectrometry). Results of this channel sample are summarised in Table 7 and Figure 4.

To develop geological undertaking on the alteration and mineralisation styles at Garfield, a petrographic study is also underway, including micro-XRF scanning of mineralised structures and rhyolites.

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 defence 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 one of America's largest producing tungsten operations, both located in Nevada, one of the top-rated mining jurisdictions in the world.

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 recently completed 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 defence, 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 defence metal.
