Adamera Minerals Corp. will offer its Talisman Copper-Silver-Tungsten Property for joint venture, positioning the Washington State project as a strategic asset in the growing critical minerals sector. The property, located near Laurier, Washington, includes the historic Talisman tungsten mine that served as a key tungsten producer during World War II, supplying strategic metal for U.S. military applications.
Tungsten's critical mineral status by multiple countries including the United States, European Union, Canada and United Kingdom underscores the project's significance. The metal's extreme hardness and high melting point make it essential for ballistics, aerospace and technology applications. The United States has not seen commercial tungsten mining since 2015, with most global supplies currently sourced from China, creating strategic vulnerability in the supply chain.
Adamera's mineral potential review revealed grades of 0.35-1.0% WO₃ at the property, with selected samples from mine workings confirming this range and local samples reporting even higher assays. The company's work, while initially focused on high-grade copper and silver mineralization, has identified extensive polymetallic potential beyond the historic tungsten focus. Smelter records from the Talisman Mine indicate high-grade copper averaging 5% and silver averaging 103 g/t, with specific zones containing lead up to 20% and zinc up to 11% according to documentation available at http://mrdata.usgs.gov/mrds.
Surface sampling, mapping and geophysical interpretation demonstrate that copper, silver, zinc and lead mineralization extends well beyond the historic mine, suggesting tungsten may follow 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 original mine workings, areas that have not yet received follow-up exploration.
Geological mapping has outlined a 1.5-kilometer mineralized corridor with copper-silver-lead-zinc occurrences, multiple magnetic anomalies coinciding with surface mineralization, and continuity of alteration beyond historic mine boundaries. The skarn system, hosted within carbonate rocks intruded by granite and diorite bodies, remains open along strike and at depth with significant untested potential beneath what appears to be barren rock cover.
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. The property represents one of few known past-producing tungsten sites in Washington State with re-development potential under modern critical-minerals initiatives.
Rock samples from the property were analyzed at Act Labs, and qualified person Gordon Gibson has reviewed and approved the technical data. Historical context for the region's tungsten potential can be referenced through Washington Division of Mines and Geology Bulletin No. 37, which documents tungsten deposits throughout the state.
