The Mammoth Gold Mine NL was formed in 1935 in Melbourne, and registered in Canberra, with 100 000 pounds capital to develop the Mammoth mine. A 10 head battery was erected, with a rich first crushing. However they were unable to find the continuation of the shoot, and the following year when shareholders failed to support another call on funds, the mine closed. The battery was given to the government, and it crushed for local prospectors as a state battery until the 1950's. 104 ounces of gold was achieved during its brief mining period.

The mine is located on a north-west to south-east trending shear zone, of banded iron formation, dolomite, with malachite staining, minor magnetite, south of and parallel to the shear. Country rock is greywacke, siltstone, shale and tuffs of the Warramunga Formation. Testing of the mine site in the 1980's found low gold values, moderate levels of Bi, and high copper around the old battery site.

The mine site is 15 kilometres east of Tennant Creek. To reach head east along a rough track from the Tennant Creek repeater station. When inspected in the 1980's the site contained several shallow pits, shafts, and adit, and historically a tunnel is noted. The state of the old workings is unclear, as all that can be seen is a bulldozed area, and an on the ground inspection is needed. The site borders the southern side of the track.
