A number of showings are aligned north-south for 3 kilometres, starting from just inside Glacier National Park (Edinburgh, 082N 029; Elizabeth, 082N 030; Scotia, 082N 031) parallel to the Incomappleux River, about 750 metres east of the river, approximately 48 kilometres east of Revelstoke. These showings were previously covered by claims staked in the early 1890s and comprise the Edinburgh (082N 029), Elizabeth (082N 030), Scotia (082N 031), Annie, Agnes (082N 033), Heronback (082N 034) and Salmon (082N 035), aligned north-south starting from the north.

The area is underlain by a steeply dipping package of rusty weathering, thinly bedded, black, metamorphosed argillite and silty argillite of the Lower Cambrian and younger Lardeau Group, intruded by an Early and/or mid-Cretaceous biotite granite intrusion. The argillites have been extensively hydrothermally altered resulting in considerable deposition of manganese.

Quartz and quartz-carbonate zones from 3 to 4 metres wide occur in a north striking, vertical shear zone in argillite. Up to 6 metres of manganese alteration occurs on either side of the shear zone along with seams of manganite. Mineralization in the quartz- carbonate and quartz consists of seams and veins of argentiferous galena and some sphalerite.

At the Annie occurrence, an adit has been driven 45 metres along the vein and a dump of shipping ore assayed 2742 grams per tonne silver and 72 per cent lead (Minister of Mines Annual Report 1896, page 540).
