A former underground gold mine.
The mine produced about 4,600 ounces of gold. In 1902 a 400 foot long tunnel was driven from the Anthill Mine to the other side of the ridge, to reach the aerial hoppers which took ore down to the Taitapu battery in the Slaty Gorge. The battery closed in 1906.
Gold is usually found in the Mine Beds unit on the goldfield, but is absent in the Anthill workings. There were three levels at the mine, with the most gold in weathered sections, with supergene action increasing gold values. The mine contained thick and thin quartz veins up to 2 metres long each, with also lensoid and irregular masses of quartz, all containing gold.
The mine is about 500 metres north of the Aorangi Mine. Mindat map approximate.
