Black Mammoth Metals Corporation announced the commencement of a property-wide ground gravity survey at the Company's now 1,213 hectare 100% owned Happy Cat gold property in southern Ravenswood Mining District, Lander County, Nevada. The gravity survey area substantially covers the 12 square kilometer Happy Cat property with a 150-meter grid, consisting of more than 500 gravity stations. This is the first known ground gravity survey that has been conducted on the Property and is part of the Company's efforts to refine the Property's Carlin-like drill targets with systematic modern exploration.

Ground gravity is known to contribute to identifying new structural and stratigraphic features in Carlin-like environments along with confirming the existing structure and stratigraphy that has been indicated by the Company's recently completed UAV magnetic survey and ongoing geologic work.
