The Val property is located about 6.4 kilometres south of Greenwood at the elevation of 1400 metres on the south-facing slope of Mount Attwood. Access is via the McCarren Creek road which turns east off of Highway 3 near Boundary Falls. At 9 kilometres on the McCarren road there is a left turn onto a little used bush road which leads to the property 3 kilometres to the northwest.

The property is underlain by cherts and phyllites of the Knob Hill Group which have been intruded by dioritic dikes of various ages. Silica occurs in these host rocks as large tabular bodies of massive, fine grained white quartz. The origin of the quartz body is unknown but there is some agreement that it is a vein, although a few authors believe it to be the result of remobilization of a cherty beds in the Knob Hill Group. The æveinÆ has been traced easterly on strike for 350 metres. A second smaller vein occurs on strike 400 metres further east. Several samples analysed by the Geological Survey Branch returned 98.7 per cent silica.
