Adamera Minerals Seeks Joint Venture for Washington State Tungsten Property Amid Critical Minerals Demand
Adamera Minerals Corp. is offering its Talisman polymetallic property in Washington for joint venture, highlighting its potential as a strategic tungsten source at a time when the U.S. lacks domestic production of this critical mineral essential for defense and technology applications.
Adamera Minerals Corp. will offer its Talisman Copper-Silver-Tungsten Property near Laurier, Washington for joint venture, positioning the historic tungsten mine as a strategic asset amid growing demand for critical minerals. The property includes the Talisman tungsten mine, which was a key producer during World War II, supplying strategic metal for U.S. military applications.
Tungsten is considered a critical mineral by the United States, European Union, Canada and United Kingdom due to its importance in ballistics, aerospace and technology applications. The metal has not been mined commercially in the United States since 2015, with most global supplies currently sourced from China. This creates strategic importance for domestic tungsten sources like the Talisman property.
Adamera's mineral potential review of the property identified grades of 0.35-1.0% WO₃, with local samples reporting even higher concentrations. The company's work has focused primarily on high-grade copper and silver mineralization, with limited attention paid to the historically mined tungsten-bearing scheelite skarn zones. According to historical data referenced in Talisman Mine records, smelter records from the mine report high-grade copper averaging 5% and silver averaging 103 g/t, with specific zones containing lead up to 20% and zinc up to 11%.
Mark Kolebaba, President and CEO of Adamera Minerals Corp., stated that the Talisman Property represents a critical minerals opportunity containing a polymetallic mineralized system with tungsten, copper, silver, lead, zinc and bismuth observed at shallow depths. Exploration has demonstrated that the mineralizing system extends well beyond the old tungsten mine workings, suggesting potential for discovery of a much larger polymetallic deposit.
Surface sampling, mapping and geophysical interpretation by Adamera show that copper, silver, zinc and lead mineralization extends significantly beyond the historic mine, with tungsten likely following similar patterns. The company has 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 mine that have not yet been followed up.
The Talisman Mine is hosted within carbonate rocks intruded by granite and diorite bodies, forming extensive skarn alteration along contact zones. Adamera's mapping has 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 the historic mine workings. The company believes the skarn system remains open along strike and at depth, with significant untested potential beneath a likely barren rock unit.
A drill program has been prepared to test below and along strike of the 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 survey. The property represents one of the few known past-producing tungsten sites in Washington State with strong potential for re-development under modern critical-minerals initiatives.
The combination of historical tungsten production and newly identified copper-silver enrichment positions Talisman as a strategic exploration asset in a geopolitically secure jurisdiction. By seeking joint venture partners, Adamera aims to advance exploration while focusing resources on its core gold assets, recognizing the property's potential significance in addressing critical mineral supply chain concerns.
