The Lee occurrence is situated on the southwest slopes of Mount Ogden, approximately 70 kilometres west-northwest of Germansen Landing. Initial discoveries of "placer" jade boulders in the area were made between the years 1967 and 1969, but it was not until late 1969 that in-situ nephrite was discovered. It is one of many occurrences eventually located in the Ogden Mountain area (see 093N 156, 165).

The region is underlain by a northwest-trending, fault-bound belt of argillite, chert, limestone and greenstone of the Carboniferous to Jurassic Cache Creek Complex. Locally, these rocks have been intruded(?) by sill-like bodies of serpentinite formerly assigned to the Middle Permian to Late Triassic Trembleur intrusions and now termed Mississippian to Triassic Oceanic Ultramafites.

Nephrite jade occurs in a zone, exposed over a length of 45 metres, along the contact between serpentinite and other Cache Creek rocks. Part of the zone consists of talc schist and rodingite, which together with the jade, is up to 3 metres wide.

Jade was produced by Teegee Explorations and New World Jade Ltd. in the early 1970s, during the early stage of development of the deposit. Most of this production came from loose parts of the deposit and from blocks and boulders in the vicinity of outcrop. Production for 1971 is estimated at 90 to 140 tonnes (National Mineral Inventory card). Production in 1988 was 22,000 kilograms, all of which was marketed in China (Mining in British Columbia 1988, page 87).
