BLACK MAMMOTH METALS IDENTIFIES IP TARGET CORRIDOR AT COAL CANYON GOLD, NV

Black Mammoth Metals Corp. has released the results of a pole-dipole induced polarization (IP) survey with an interpreted inversion model conducted at its Coal Canyon gold project, situated in Pershing county, Nevada, on the west side of the Humboldt Range, approximately 14 kilometres (km) southwest of the Coeur Rochester silver-gold operation.

IP survey -- results

A zonation of resistivity and chargeability anomalies have defined a target corridor trending north-northeast that is coincident with the known gold mineralized area observed in the company's recent surface rock chip samples. The IP survey has also identified previously untested target zones that may be associated with an interpreted mineralized intrusive partially exposed in road cuts that could be reflected in the resistivity high and the enveloping chargeability anomaly located in the centre of the survey area.

The IP survey was selected for the property to follow up with the company's road cut sampling that assayed up to 46 metres (m) at 0.76 gram per tonne (g/t) gold (Au) in oxide (see the company's news release dated May 28, 2025) and verification of historical sampling. Multiple types of mineralization exist on the property, and an extensive soils grid shows strong silver and molybdenum values surrounding the gold zone. The IP survey consisted of four east-west IP lines with 100 m spacing, situated in the south of the property.

The company intends to further investigate the targets defined by the IP survey.

At Coal Canyon, there is an existing drill permit with the Bureau of Land Management that needs a change of operator. Substantial drill roads and pads have been constructed.
