Black Mammoth Metals Finds Large Chargeability Anomaly Underlying the Historic Workings and Stakes Claims at Amador Silver Property, NV

BMM: TSX-V

VANCOUVER, BC, Dec. 8, 2025 /CNW/ – Black Mammoth Metals Corporation (TSXV: BMM) (OTC: LQRCF) (“Black Mammoth” or the “Company”) is pleased to announce the results of a recently completed induced polarization survey (the “IP Survey”) and has interpreted the related inversion model at its 100% owned Amador property (“Amador” or the “Property”) in Lander County, NV. The IP Survey’s objective was to investigate if significant sulfide mineralization is present underneath the historic Amador mine workings and along the related shear zone as sulfide mineralization produces characteristic chargeability and resistivity responses.

Survey Results:

The IP Survey has delineated a large high-chargeability anomaly, with high-resistivity (the “Anomaly”) extending at least 1.22 km along the range-front and under the historic Amador mine workings, where historic drilling and the Company’s recent rock chip sampling encountered significant silver mineralization. The Company’s recent rock chip samples assayed up to 23.05 oz/t silver (see the Company’s news dated July 22, 2025) while the historic drilling in this area has not been followed up on. The 0–50m IP depth slice aligns well with geophysical and sampling criteria (see Figure 1), while the 150-250m depth slice indicates a potential NE dip of the sulfide mineralized zone (see Figure 2).

The workings of the historic Amador mine consist of at least 3 shafts, 3 adits and numerous exploration pits. The silver mineralization 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. The Amador property has been explored in recent years (2003-2010) with operators reporting significant silver mineralization in rock chips and in 3-to-12m drill intervals.

Claims Staking:

The Company has newly staked 55 unpatented lode claims at Amador. The range-front claims are administered by the Bureau of Land Management (BLM) while the claims uphill to the East are managed by the US Forest Service. Together with the 23 existing claims, the Property now covers a total of approximately 631 hectares (1560 acres).

The Company initially intends to permit five drill sites with a BLM Notice of Intent to test the chargeability anomaly which encompasses the high-grade silver shear zone along the range-front and its potential deeper extension to the West.
