The Alps-Alturas property is located on the east side of Dolly Varden Peak, 14 kilometres northeast of Slocan Lake. Access can be gained by bush road leading up the east side of Wilson Creek from the town of Rosebery on Slocan Lake. The last portion of the route is a footpath.

There is little geological information on the occurrence, however the 1928 Minister of Mines Annual Report describes a 1.2- metre quartz vein which carries disseminated to massive stibnite hosted in (or associated with) serpentinized ultramafic rock described in Assessment Report 20939 as "locally altered to listwanite quartz-carbonate-mariposite". Ninety-five tonnes of shipped ore averaged 57.2 per cent antimony. Gold values are low. The showing is close to the contact between Permo-Triassic Kaslo Group mafic volcanic rocks and Triassic Slocan Group clastic sedimentary strata (GSC Open File 432).

Twenty four and one-half tonnes of antimony ore grading 50 to 60 per cent antimony is reported to have been shipped from the property in 1916 (Minister of Mines Annual Report 1916). The information regarding activity between 1916 and 1926 is sparse. However, in the 1928 Minister of Mines Annual Report it is estimated that there had been a cumulative production of 95 tonnes averaging 57.2 per cent antimony. The 1928 Minister of Mines Annual Report states that two adits tested the vein, the lower one advanced 73 metres and the upper one, 30 metres higher on the mountain, advanced 30 metres. The ore was extracted from the first 20 metres of the lower adit.

In 1990, Black Tusk Explorations Limited (Assessment Report 20939) completed reconnaissance lithogeochemical sampling (40 samples analysed for gold, silver, copper and antimony), geological mapping and prospecting. In 1994, additional prospecting was undertaken (Assessment Report 23235).
