Adamera Minerals Seeks Joint Venture for Washington Tungsten Property Amid Critical Minerals Demand

Adamera Minerals Corp. announced plans to seek joint venture partners for its Talisman Copper-Silver-Tungsten Property in Washington state, positioning the historic mine site as a potential source of critical minerals including tungsten, which has not been commercially mined in the United States since 2015. The company's mineral potential review identified grades of 0.35-1.0% WO₃ at the property near Laurier, Washington, with historical records indicating even higher localized concentrations.

Tungsten's classification as a critical mineral by multiple governments including the United States, European Union, Canada and United Kingdom underscores the strategic importance of domestic sources. The metal's extreme hardness and high melting point make it essential for ballistic, aerospace and technology applications, with current supplies predominantly sourced from China. The Talisman Mine previously served as a key tungsten producer during World War II, supplying strategic metal for U.S. military applications.

Company exploration has revealed a polymetallic mineralized system extending well beyond the historic mine workings. Mark Kolebaba, President and CEO of Adamera Minerals Corp., stated that while initial work focused on copper-silver targets, the property represents a critical minerals opportunity containing tungsten, copper, silver, lead, zinc and bismuth mineralization observed at shallow depths. Surface sampling identified zones with elevated tungsten ranging from 100 to 2600 ppm and bismuth from 100 to 2850 ppm located 700 to 1500 meters from the original mine.

Geological mapping outlined a 1.5-kilometre mineralized corridor with copper-silver-lead-zinc occurrences, multiple magnetic anomalies coinciding with surface mineralization, and continuity of alteration beyond historic workings. The skarn system remains open along strike and at depth, with significant untested potential beneath what appears to be barren rock. Historical documentation from sources including Talisman Mine records and Washington Division of Mines and Geology Bulletin No. 37 indicates high-grade copper averaging 5% and silver averaging 103 g/t, with specific zones containing lead up to 20% and zinc up to 11%.

The company has prepared a drill program to test below and along strike of former mine workings, targeting both high-grade scheelite zones and associated copper-silver-bearing sulphides. Additional planned work includes systematic soil and rock geochemistry focusing on tungsten and detailed electromagnetic surveys. As one of few known past-producing tungsten sites in Washington State, the property represents a strategic exploration asset in a geopolitically secure jurisdiction at a time when critical minerals initiatives are gaining prominence.

Adamera's decision to joint venture the property allows the company to focus on its gold assets while ensuring continued exploration of the Talisman Property's polymetallic potential. The combination of historical tungsten production and newly identified copper-silver enrichment positions the site for potential redevelopment under modern mining approaches and critical minerals priorities.
