The Poorman workings are reported (Minister of Mines Annual Report 1930, page A262) to be located on the west side of Blue Grouse Creek, approximately 10 kilometres northeast of Burton.
This area is underlain by east trending metasedimentary rocks (mainly argillites) and mafic volcanic rocks of the Triassic Slocan Group. Quartz monzonite of the Cretaceous Halifax Creek stock outcrops south of the area.
The showing is said to be a "crushed zone of graphitic slate" (Minister of Mines Annual Report 1930, page A262) containing "small lenses of zinc and lead sulphides carrying good silver values". A selected sample assayed 15.1 grams per tonne gold, 570 grams per tonne silver, 3 per cent lead and 11 per cent zinc (Minister of Mines Annual Report 1930, page 262).
Physical work on the property consists of an 8-metre adit, a shallow shaft and several trenches (Minister of Mines Annual Report 1930, page 262).
