The Snyder occurrence is located west of the centre of Upper Dam Lake (Anyox Creek), and 7 kilometres northeast of the Anyox smelter (103P 021).

The region is underlain by a roof pendant, consisting of volcanic and sedimentary rocks, within the Eocene Coast Plutonic Complex. These pendant rocks have been correlated with Middle-Upper Jurassic Hazelton Group rocks and overlying upper Middle to Upper Jurassic Bowser Lake Group sedimentary rocks (Geological Survey of Canada Open File 3453). The Hazelton rocks consist of variably chloritized pillow and massive basalt with minor mafic tuffs. The overlying Bowser Lake sediments consist of siltstone and sandstone with minor chert and limestone.

The Snyder showing is a massive quartz-carbonate vein exposed in scattered outcrop over a 50 metre strike length hosted in pillow basalt. The vein dips steeply and averages 30 centimetres in width. Over a small section of its total length, this vein contains up to 60 per cent fine pyrite and marcasite as scattered blebs or knots within the quartz.

A sample of the material yielded 0.064 gram per tonne gold, 81 parts per million copper, 30 parts per million zinc, 30 parts per million lead and 0.6 gram per tonne silver (D.J. Alldrick, B.C. Geological Survey, unpublished data, 1998).
