The Fivemile Point deposit is just east of the Troup Junction near the southeast shore of the west arm of Kootenay Lake, 5 kilometres northeast of Nelson. Access from Nelson is via the Canadian Pacific Railway line.

The mineralization was discovered in 1904 by George Huston and associates, of Sandon. A drift adit was driven about 23 metres. In the fall of 1904 Hall Mining and Smelting Company, Limited, operator of a smelter at Nelson, optioned the property and mined a bulk sample for test purposes.

The Fivemile Point fluorite deposit is a vein occupying a fissure in sheared Nelson granite. The vein strikes 120 degrees and dips 90 to 55 degrees northeast. The filling is a band of fluorite, crushed granite and gouge having a maximum thickness of 1.1 metres.

A band of bluish and purplish fluorite, up to 35 centimetres wide, occurs along and near the footwall, and smaller parallel streaks lie in the central and hangingwall parts of the vein, together with some light grey siliceous streaks. Vugs up to 0.3 metre in diameter, with concentrically banded borders are common. Barite is found locally as minute crystals and aggregates on the fluorite.

A few tonnes of fluorite were mined from an adit in 1904, but silica content proved to be higher than desirable.
