The Calumet property is at about 2000 metres elevation on the ridge east of Dayton Creek, 5 kilometres due east of Slocan. Access to the property is from a switchback mountain road that joins the Springer Creek road at Coldwell Creek, about 8 kilometres by road east of the Slocan highway.

The Calumet property, first staked in 1895, comprises the Calumet No. 2, Buffalo and Hecla claims and fractions. The property was trenched by Slocan Hughes Mines Ltd. in 1963 and by Goldstream Mines Ltd. in 1970.

A quartz vein cutting granitic rocks of the Nelson batholith and a large metasedimentary xenolith (the Slocan Group ?) has been explored by an adit crosscut and drift. The vein is intercepted by the tunnel at 46 metres from the portal. It strikes about 060 degrees and dips steeply northwest and has been drifted on for 90 metres, partly in metasediment rocks and partly in the granite. In the metasedimentary rocks the vein is irregular and consists of barren quartz, however, in the granite the vein is regular, about 1.5 metres wide, and contains galena, sphalerite and barite. In this section of the tunnel the best samples grade 280 grams per tonne silver and 12 per cent lead.
