Adamera Minerals Offers Talisman Property for Joint Venture Amid Critical Minerals Demand

Adamera Minerals Corp. will offer its Talisman Copper-Silver-Tungsten Property for joint venture, located near Laurier, Washington, which includes the historic Talisman tungsten mine. While not core to the company's business, the project warrants exploration due to increased demand for critical minerals. Adamera has conducted a mineral potential review where grades of 0.35–1.0% WO₃ have been reported according to documentation from Tungsten Deposits of Washington.

Tungsten is considered a critical mineral by many countries including the United States, European Union, Canada and United Kingdom due to its importance in ballistics, aerospace and technology. The metal has not been mined commercially in the USA since 2015, with most supplies sourced from China. The Talisman Mine was a key tungsten producer during World War II, supplying strategic metal for U.S. military applications. Work by Adamera has focused on high-grade copper and silver mineralization, with limited attention paid to historically mined tungsten-bearing scheelite skarn zones.

Scheelite occurs in garnet-epidote skarn along the contact between limestone and intrusive rocks. Selected samples from the workings contain between 0.35 and 1.0% WO₃, with local samples reported to assay higher. In addition to high-grade tungsten, smelter records from the Talisman Mine report high-grade copper and silver averaging 5% and 103 g/t respectively, 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, with clear potential for discovering a much larger polymetallic deposit.

Surface sampling, mapping, and geophysical interpretation demonstrate that copper, silver, zinc and lead mineralization extends well beyond the historic mine, suggesting tungsten may do the same. 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 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 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 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 work will include 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.
