Pyrophyllite is periodically mined along a logging road 1.2 kilometres northeast of the Tulameen River and 9.0 kilometres northwest of Princeton.

The pyrophyllite is hosted in volcanics of the Upper Triassic Nicola Group. The occurrence appears to be related to a major fault zone. The ore is a mixture of quartz and pyrophyllite with scattered grains of pyrite. Shears and fracture faces are filled with quartz and fine-grained powdery pyrophyllite. A grab sample of the ore taken from the centre of stripping, where the rock is more light grey-white coloured and surrounded by brown-stained material, contained 80.96 per cent silica, 13.24 per cent alumina and 0.13 per cent iron (Minister of Mines Annual Report 1959, page 184).

Since 1972, pyrophyllite from this property has been used by Clayburn Refractories Limited for refractory products manufacturing at the company's ceramics plant in Abbotsford at a rate of several hundred tonnes a year. Reserves are reported to be sufficient for 20 years at current production rates (B. Warner, personal communication, 1991). The material is stockpiled on the mine site and in Princeton and is shipped to the Abbotsford plant whenever there is a demand for it.
