Adamera Completes Underground Inspection of the Talisman Tungsten Mine, Washington State
Adamera confirms underground access at Talisman, enabling shallow drilling within the Western Australian tungsten hub.
Adamera Minerals Corp. (ADZ) completed an underground site inspection of its Talisman Tungsten Mine in Washington State, conducted by JDS Energy & Mining Inc. The inspection confirmed that historic underground workings are in competent, stable rock with no water management or ventilation issues. Only minor ground support is required to re-establish safe access.
Preliminary visual observations and portable XRF (pXRF) data identified chalcopyrite, scheelite, and sphalerite in the portal and adit, consistent with a potentially larger mineralized system extending beyond previously mined zones. A 3D magnetic inversion model indicates the magnetic body extends to depths of more than 200 metres below the ~30 metres that was historically mined.
Over 200 soil samples were collected in the southern zone on a 25-metre spacing grid to define the extent of the mineralizing system and generate drill targets. Results are currently pending.
Historical production context includes early 1900s shipments (521 tons @ 5% Cu, 4.1% Zn, 3 oz/t Ag), later lead-zinc zones, and post-1951 tungsten focus (0.35% to 1.0% WO3).
Adamera Minerals Corp. (ADZ) confirmed the physical feasibility of accessing historic workings for geological mapping and potential drill access, validating the company's exploration strategy. This update follows the June 2026 announcements that established the "Washington Tungsten Hub" and identified three drill targets via magnetic modeling.
The release provided no new financial data, resource estimates, or drilling results. Preliminary pXRF data was noted in the technical disclaimer as not indicative of grade, continuity, or economic potential.
Adamera Minerals Corp. (ADZ) is a pre-revenue junior explorer focused on precious and critical metals across Washington State and British Columbia. Its flagship project is the Talisman Tungsten Mine in Washington State, a historic polymetallic skarn mine (W-Cu-Ag-Pb-Zn) featuring 600m of historic underground development. The company is consolidating a "Washington Tungsten Hub" that includes the Talisman, Tungsten Ridge, Pierre Creek, and Roosevelt properties.
The company’s secondary project is South Hedley in British Columbia, a 24,000+ hectare property featuring the Max Copper-Gold porphyry target and the Glix gold skarn prospect. Adamera Minerals leverages modern geophysics, including 3D magnetic inversion and IP surveys, alongside geochemistry to identify drill-ready targets in established mining districts.
