The purchase, completed through a wholly owned U.S. subsidiary, totals US$1.3 million in cash.

Insights

Mining sector and project finance analyst

Small cash deal secures critical land and water for Tempiute.

Guardian Metal Resources is buying Lincoln Estates for US$1.3 million, adding 841 acres and 2,540 acre-feet per year of water rights near its Tempiute Tungsten Project. Proximity and direct highway access strengthen logistical and permitting fundamentals around a potential future mine.

The company highlights this as a de-risking milestone, since water access can be a bottleneck for mine development in arid regions. However, the announcement also stresses that there is no assurance these rights will ultimately support a mining operation or that Tempiute will proceed to development or production.

Investors may focus on how these assets integrate with ongoing Tempiute workstreams, including resource-focused drilling described in the update. Subsequent technical studies and regulatory milestones at Tempiute and Pilot Mountain will be important to gauge whether this modest acquisition translates into higher project value.

Key Terms

acre-feet, water rights, forward-looking statements, Defense Production Act of 1950, +2 more

6 terms

acre-feet financial

"2,540 acre-feet of annual water rights."

An acre-foot is a unit of water volume equal to enough water to cover one acre of land to a depth of one foot, roughly 325,851 gallons (about 1,233 cubic meters). Investors see it as a practical measure for valuing water assets, rights, reservoirs and the revenue of utilities or agricultural operations—think of it like counting barrels of oil but for water supply and demand.

water rights financial

"2,540 acre-feet per annum of water rights across three permits"

Water rights are legal entitlements that allow a person or company to withdraw, use, or store water from a river, aquifer, lake or other source. For investors they matter because these rights are assets that affect a business’s ability to operate, expand or sell — like owning a reserved parking spot or deed for a piece of land that guarantees access to a needed resource. Limits, permits and local rules can change value and risk.

forward-looking statements regulatory

"This announcement contains forward-looking statements relating to expected or anticipated future events"

Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.

Defense Production Act of 1950 regulatory

"under Title III of the Defense Production Act of 1950, as amended, invested US$6"

A U.S. law that gives the president temporary authority to direct industrial production, prioritize and allocate materials, and speed up manufacturing for national defense needs. For investors it matters because the law can shift demand and revenue quickly by steering government contracts and supply chains toward certain companies or industries, much like a coach reallocating players to meet an urgent game plan, which can boost some firms while disrupting others.

pre-feasibility study financial

"to support the Pilot Mountain PFS."

A pre-feasibility study is an initial assessment that evaluates whether a proposed project or investment idea is worth exploring further. It involves examining basic factors like costs, potential benefits, and possible challenges, similar to conducting a preliminary check before deciding to invest more time and resources. This helps investors determine if pursuing the project further is practical and likely to be successful.

Acquisition of Lincoln Estates & Water Rights

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 the acquisition of Lincoln Estates Group LLC ("Lincoln Estates") which includes 841 acres of real property as well as 2,540 acre-feet of annual water rights. Lincoln Estates is located less than 10 miles from 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. 

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. 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.
