Arizona Tribune - Guardian Metal Resources PLC Announces Acquisition of Lincoln Estates & Water Rights

Securing water and land rights marks an important milestone for the Project as its various workstreams advance. Combined with Tempiute's existing infrastructure, this acquisition enhances the Project's development potential and advance Guardian Metal's goal of building a resilient U.S. domestic tungsten supply chain, reducing reliance on foreign sources while reinforcing economic and defense security.

Acquisition Highlights:

• 2,540 acre-feet per annum of water rights across three permits currently banked with the Lincoln County Water District.

• Approximately 841 acres of real property rights that are zoned for mixed use, commercial, industrial, and single family.

• Direct access off Highway 375, the same access highway for Tempiute.

• Guardian Metal retains the right to assign and/or transfer the beneficial interest in the water rights for use within the service area, which includes Tempiute.

• The acquisition of Lincoln Estates represents a key derisking milestone as the Company continues to advance Tempiute across multiple active workstreams.

Oliver Friesen, CEO of Guardian Metal, commented:

"We believe securing these water and property rights materially de-risks and supports the accelerated advancement of the Tempiute Tungsten Project. These rights, together with the substantial infrastructure remaining from Tempiute's last period of operation in the 1980s, further strengthen the Project's foundation for redevelopment.

Our on-site team continues to make meaningful progress across multiple workstreams, and this acquisition secures a range of strategic opportunities that will facilitate the next stages of project exploration and development. We look forward to providing further updates as these workstreams advance, including ongoing resource-focused drilling."

Commercial Terms:

The total purchase price for 100% ownership of Lincoln Estates is US$1.3 million, payable in cash, completed through Golden Metal Resources, LLC, one of the Company's wholly-owned U.S. subsidiaries.

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.

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.
