BLACK MAMMOTH METALS OBTAINS DRILL PERMIT FOR AMADOR SILVER, NV

Black Mammoth Metals Corp. has received final approval to drill test priority targets at its 100-per-cent-owned Amador silver property. Up to six drill sites have been selected, where multiple boreholes may be drilled at each site, all on lands administered by the Bureau of Land Management.

The company intends to test the high-chargeability-with-high-resistivity anomaly at Amador, which encompasses the high-grade silver shear zone extending at least 1.22 kilometres along the range front.

• Black Mammoth's recent induced polarization survey with inversion model delineated the anomaly along the range front and under the historic Amador mine workings (see the company's news release dated Dec. 8, 2025). Sulphide mineralization produces characteristic chargeability and resistivity responses.
• Overlapping the anomaly area, historic drilling encountered significant silver mineralization that has not been followed up to date, and the company's recent rock chip sampling assayed up to 23.05 ounces per ton silver (see the company's news release dated July 22, 2025).

Amador consists of 78 unpatented lode claims covering approximately 631 hectares and is situated on the west side of the Toiyabe range, 7.3 kilometres north of the historic silver mining town of Austin in Lander county, Nevada. The silver mineralization at Amador is hosted in a quartz vein shear, which appears to have been developed along a contact zone of Devonian sediments (Slaven chert) with plutonic intrusive.
