The Riverside property, comprising the Riverside, Almeda, Autumn and Lailey fraction Crown Granted claims, is situated on the ridge between Enterprise Creek and Arlington basin, 12 kilometres northeast of Slocan. Access is by trail from the Arlington and Springer Creek roads.

On this property three adits spaced about 60 metres vertically apart explore a quartz vein cutting coarse grained, porphyritic Nelson granite. The vein strikes northeast and dips steeply southeast. Underground work on the vein consists of about 120 metres of drifting which has exposed small pockets enriched with pyrite, sphalerite and galena associated with high silver values. A sample from a pile of 2 tonnes of ore extracted from the upper adit in 1919, assayed 3000 grams per tonne silver and 7.5 per cent zinc. In the period 1935 to 1937, production totalled 18 tonnes, yielding 27,619 grams of silver, 453 kilograms of lead and 419 kilograms of zinc.
