The Moha prospect is on the southeast side of Bridge River, 0.8 kilometre southeast of the confluence of Yalakom River with Bridge River.
The prospect covers a quartz vein 15 to 38 centimetres wide within fractured andesitic greenstone of the Mississippian to Jurassic Bridge River Complex (Group). The vein contains native gold; no sulphides have been reported. In 1935, 93 grams of gold and 31 grams of silver were recovered from 12 tonnes of vein material (Minister of Mines Annual Report Index 3).
