The No.31 (Falls) occurrence is located on Blackbear Creek, approximately 2.5 kilometres east-southeast of its junction with Spanish Creek.

The area is within the Quesnel terrane of the Intermontane Belt near its eastern margin, adjacent to the Precambrian to Paleozoic rocks of the Omineca terrane. The dominant lithologies comprise red-brown weathering phyllite, grey siltstone and interbedded felsic tuffs, which form the lowermost part of the Upper Triassic to Lower Jurassic Nicola Group. Formerly referred to as "black phyllite", this unit has been thrust onto the older rocks of the Omineca terrane, with which it has been deformed and metamorphosed, probably during the Middle to Late Jurassic.

Locally, a quartz vein, greater than 1.25 metres wide, is sparsely mineralized with galena.

In 1967, a select sample assayed 1471 grams per tonne silver (Property File - A.F. Reeve [1967-01-01]: Summer Report on Keweenaw Syndicate General Prospecting Programme, Cariboo District).

In 2010, a grab sample (PS-04) from a trench (PS-1), located a short distance to the north, yielded 1480 grams per tonne silver and 42.6 per cent lead (Assessment Report 32209).

The area has historically been explored in conjunction with the Providence (MINFILE 093A  003) past-producing mine. In 1967, a program of regional prospecting and sampling was completed by the Keweenaw Syndicate. In 1972, Stokes Exploration completed a program of soil sampling on the area as the BG claims. In 2010, Barker Minerals Ltd. completed 2000 metres of trenching in 12 trenches on the area.
