The Capello Group of Crown-granted claims (Capello, Dewery, Wallace, Turris and Florence) are located on the south side of Mount Carpenter (Goat Mountain), 1.5 kilometres northeast of New Denver. They are at the north end of the Slocan mining camp, which produced silver from polymetallic vein deposits.

On the Capello property, four or five nearly parallel quartz-calcite veins occur in well-defined faults cutting quartz monzonite of the Mount Carpenter stock. The veins strike 025 degrees, dipping 35 to 40 degrees to the northwest. Vein widths average 15 centimetres but vary to 90 centimetres, which includes brecciated wallrock. Mineralization within the veins consists of tetrahedrite, argentite, ruby silver, native silver and pyrite, with gold values apparently associated with pyrite. The property was known as a producer of "dry ore" - ore carrying no lead or zinc (GSC Memoir 184). High-grade mineralization tends to occur on the hangingwall side of the vein (GSC Memoir 184).

The host Mount Carpenter stock is mainly composed of biotite hornblende quartz monzonite (GSC Open File 432) of Mesozoic to Tertiary age. The stock intrudes Triassic Slocan Group fine grained clastic sedimentary rocks which include phyllite, argillite, quartzite, tuffaceous rocks and minor limestone.

Considerable underground work has been completed on the veins, and workings cover a vertical range of 300 metres on several claims. The principal vein, located on the Capello claim, has been explored in two crosscut adits as well as by drifts and raises (GSC Memoir 184). Recently, the Florence Crown grant was re-staked and extensions of the main Capello vein system were relocated (Assessment Report 16112).

Intermittent production from 1899 to 1980, totalled 177 tonnes, resulting in 2,464,602 grams of silver, 1337 grams of gold, 386 kilograms of lead and 121 kilograms of zinc.
