Oliver Friesen's Guardian Metal Resources is developing US-based tungsten and copper deposits aligned with Pentagon critical-mineral priorities.
Guardian Metal Resources
Guardian Metal Resources is a publicly listed exploration and development company focused on tungsten, copper, and other strategic metals in the western United States. The firm's primary assets sit in Nevada and Arizona, states whose mining jurisdictions are well-understood by institutional capital but whose critical-mineral deposits are now attracting new attention from defense contractors and Washington policymakers. Friesen and his team are not speculators in exotic jurisdictions; they are building permitted, drill-defined resources within existing US mining corridors. The firm's flagship project is the Pilot Mountain Tungsten Project in Nevada, which hosts one of the largest undeveloped tungsten resources in the United States. Tungsten has no viable domestic US production as of 2024, making the Department of Defense an explicitly interested downstream customer for any successful mine buildout. Guardian also holds the Garfield copper project in Arizona, a state that already produces the majority of US copper. The company's strategy therefore spans two Defense Production Act Title III-eligible commodities — tungsten and copper — both critical to munitions, armor, and electrical infrastructure. Guardian Metal Resources trades on the London Stock Exchange under the ticker GMET, a structure that gives it access to UK and European institutional investors who increasingly screen for supply-chain resilience themes. The firm has no announced AUM figure or production profile, consistent with an early-stage developer that is currently drilling and permitting rather than mining. As of early 2025, the company has been expanding its resource definition drilling at both Pilot Mountain and Garfield, generating data that would support eventual mine feasibility studies and offtake negotiations with industrial and government counterparties. What distinguishes Guardian Metal Resources from a junior mining explorer is its asset-level alignment with US industrial policy. The company is not simply betting on rising commodity prices; it is positioning two undeveloped deposits directly in the path of the US government's most explicit mineral-security priorities. The permitting risk and capital intensity remain real, but the demand-side structure — a defense establishment legally mandated to secure domestic tungsten supply — is atypical for a company of this scale.

Frequently asked questions
What does Guardian Metal Resources actually do?
Guardian is a mineral exploration and development company that holds tungsten and copper assets in Nevada and Arizona. Its flagship Pilot Mountain project is one of the largest undeveloped tungsten deposits in the United States. The company is drilling and permitting these assets with an explicit eye toward supplying the US defense and industrial supply chains.
Why does tungsten matter for a public company?
The United States currently has no domestic tungsten mine production and relies almost entirely on imports from China, Russia, and other nations classified as foreign-entity-of-concern under the Defense Production Act. Tungsten is essential to armor-piercing munitions, cutting tools, and aerospace alloys. The DoD has designated tungsten a critical material, and Title III of the DPA authorizes direct government investment in onshore tungsten production capacity.
How is Guardian Metal Resources funded?
Guardian trades on the London Stock Exchange as GMET and raises capital through equity placings and standard junior-mining capital markets channels. The company has not disclosed an AUM or institutional-backer lineup, but its US tungsten and copper focus aligns with several UK-based natural-resource funds that target critical minerals as a distinct allocation theme.
What is the Garfield copper project?
Garfield is Guardian's copper exploration asset located in Arizona, a state that already accounts for the majority of US copper production. The company is conducting resource-definition work there. Copper is on the US critical minerals list and demand is forecast to grow significantly from grid modernization and electrification; Arizona's existing infrastructure reduces the permitting unknowns relative to greenfield sites in other states.
Does Guardian Metal Resources have any US government contracts or offtake agreements?
As of the most recent public disclosures, Guardian has not announced signed offtake agreements or direct funding awards under the Defense Production Act. The company is positioned as an early-stage developer with assets that are eligible for such structures, but eligibility does not constitute a commitment from the US government.
Where does the company name 'Guardian' come from?
The name reflects a deliberate branding strategy around supply-chain security. The company's corporate identity ties directly to its narrative of providing 'guard' for Western defense and industrial supply lines against reliance on adversarial tungsten and copper sources.
What are the biggest risks to Guardian Metal Resources?
The obvious risk is execution: junior mining projects fail at high rates, and both Pilot Mountain and Garfield must clear permitting, feasibility, and financing hurdles before any production revenue materializes. Commodity-price risk is relevant but secondary; tungsten and copper demand drivers are structural, but any mine is a long-dated bet on capital discipline and permitting outcomes.
