Small roadmetal quarry in sandstone with narrow tin-topaz-tungsten veins.
Relatively good topaz crystals (colourless to pale yellowish) and white to smokey quartz occur in clay pockets. Some good cassiterite crystals occur also.
Located about 200 m W of the All Nations mine and less than 2 kilometers southeast of the Shephard and Murphy mines.

Site is under an active mining lease and permission to enter is required from the Tenement Holders, No public Access.
