Adamera Minerals (TSX-V:ADZ) has completed an underground inspection at its Talisman Tungsten Project in Washington, US.
The inspection was carried out by JDS Energy & Mining at the 100% owned project. Adamera reports the assessment found host rock, stable workings, and ventilation, with no immediate impediments to safe re-entry.
CEO Mark Kolebaba says the underground workings are ‘well preserved’.
“The mineralisation seen in the adit is consistent with a potentially larger mineralised system,” Kolebaba shares.
“Knowing that the old mine is open and can be rehabilitated is important, as underground access will provide geological information and potentially drilling access for the project.”
The inspection revealed mineralisation comprising chalcopyrite, scheelite, and sphalerite in the portal and adit access. Adamera’s 3D magnetic inversion model indicates the magnetic body extends to depths exceeding 200m, below the estimated 30m previously mined.
US Geological Survey records show historical production in the early to mid-1900s shipped 521 tonnes of ore averaging 5% copper, 4.1% zinc, and 3 ounces per tonne silver. Later tungsten-focused operations reported grades of 0.35–1% tungsten trioxide.
The company has collected more than 200 soil samples over the southern zone on 25m spacing to define the mineralising system extent and generate drill targets. Sample results remain pending.
Adamera has also accelerated the expiry of 20.15 million warrants exercisable at $0.12 per share to 21 October 2026, following its shares closing above $0.16 for 10 consecutive trading days. If exercised, the warrants will generate $2.4 million in proceeds for working capital and exploration.
Adamera Minerals is advancing a tungsten portfolio in Washington, while actively exploring the South Hedley Copper-Gold Project and maintaining several drill-ready gold projects in Canada.
