The Speculator property, consisting of the Speculator (Lot 2360), Mineral Mountain (Lot 2362), Eda Fr. (Lot 2363) and Nancy (Lot 5259) Crown granted claims and fractions, is located 8.5 kilometres east-northeast of Slocan. Access from the Slocan highway is via the Springer and Speculator creek roads.

The workings consist of three adits that explore the northeast extension of the Arlington mine zone (082FNW152), which on the Speculator is crushed hornblende granite or granodiorite about 50 metres wide, within which mineralization occurs chiefly in a series of parallel fissures striking 034 degrees and dipping 65 to 70 southeast.

The ore is largely replacement of the crushed Nelson granite. The chief ore minerals are galena and lesser sphalerite, associated with disseminated stephanite, grey copper and native silver. The recorded shipments of ore in 1901, 1941 and 1951, totalled 26 tonnes that yielded 25,661 grams of silver, 5947 kilograms of lead and 413 kilograms of zinc.

A sample taken in 1987 assayed 119 grams per tonne silver, 1.55 per cent lead and 0.46 per cent zinc (Open File 1988-11). Another sample returned 4.3 grams per tonne gold, 2300 grams per tonne silver, 0.03 per cent copper, 0.135 per cent lead and 0.08 per cent zinc (Open File 1988-11).
