Adamera Minerals Corp. will offer its Talisman Copper-Silver-Tungsten Property for joint venture development, positioning the historic mine site as a strategic asset amid growing global demand for critical minerals. Located near Laurier, Washington, the property includes the historic Talisman tungsten mine, which served as a key producer during World War II, supplying strategic metal for U.S. military applications. While not core to Adamera's business, the project warrants exploration due to increased demand for critical minerals identified by multiple nations.
Tungsten has been designated 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 supply chain vulnerability makes domestic sources like the Talisman Property strategically important for national security and industrial stability.
Historical documentation from Tungsten Deposits of Washington reports grades of 0.35–1.0% WO₃ at the Talisman site, with local samples assaying even higher. The mine's historical significance extends beyond tungsten, with smelter records indicating high-grade copper averaging 5% and silver averaging 103 g/t, along with specific zones containing lead up to 20% and zinc up to 11%. These polymetallic characteristics enhance the property's economic potential beyond single-commodity focus.
Mark Kolebaba, President and CEO of Adamera Minerals Corp., emphasized 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, with clear potential for discovering a much larger polymetallic deposit than historically recognized.
Recent exploration work has revealed significant findings beyond the historic mine boundaries. 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 distribution patterns. Recent exploration highlights several significant metal values located 700 to 1500 metres from the mine, including zones with elevated tungsten (100 to 2600 ppm) and bismuth (100 to 2850 ppm) that have not yet been systematically explored.
The geological setting features 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 plus/minus tungsten occurrences, multiple magnetic anomalies coinciding with surface mineralization, and continuity of alteration beyond 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 comprehensive 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 Talisman Property represents one of the few known past-producing tungsten sites in Washington State, now recognized as having 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, offering potential partners exposure to multiple critical minerals in a single, well-located property.
