The Lily B claim is located at about 1600 metres elevation on the south slope of the valley of Springer Creek, 7.5 kilometres east-northeast of Slocan. Access is via the Springer Creek and Bettina Creek roads from the Slocan highway.

The workings, consisting of a shaft and adit, explore a fault fissure lode cutting coarse grained Nelson granite, on a strike that varies from 075 to 105 degrees, dipping 55 degrees south. The mineralized zone consists of crushed country rock and gouge, up to 1.5 metres wide, containing small lenses of ore, up to 1 metre wide. The ore consists of galena and sphalerite accompanied by a small amount of pyrite and chalcopyrite in a quartz gangue. Some native silver occurs along the fissure planes in the ore.

Shipments of ore from this mine were intermittent beginning in 1913. Altogether up to and including 1922, this mine has produced 41 tonnes of ore yielding an average of 2748 grams per tonne silver and 5.6 per cent lead.
