The occurrence is located on Jordan River, above the Diversion Reservoir.

Aluminosilicate-rich pelitic schists of the Jurassic to Cretaceous Leech River Complex (Formation) are exposed on southern Vancouver Island, outcropping between the Leech River and San Juan faults near Port Renfrew and Langford. The complex is largely comprised of argillites and metagreywackes, with some metavolcanics. Metamorphic grade increases from north to south across the unit.

In a few places, notably in the vicinity of Jordon River, the quartz-biotite and quartz-sericite schists contain large amounts of garnet, staurolite and sillimanite. To the west, kyanite has been observed. The exposed southern one-third to one-half of the Leech River unit contains staurolite and andalusite, with the latter forming porphyroblasts up to 20 centimetres in length (see Leech River, 092B 102).

The sillimanite occurs in short to long slender prisms, of rectangular or hexagonal cross-section, that are rudely oriented parallel to foliation. They have a maximum length of about 5 centimetres and a maximum width of 4 to 5 centimetres. Garnet occurs in small (averaging less than 2 millimetres in diameter) pinkish, dodecahedral crystals. Staurolite, not usually conspicuous in hand specimens, forms small, yellowish grains between the lamellae of biotite and quartz; in a few places distinct single and twin crystals are seen.

Within a relatively narrow zone west of the Jordan River are carbonaceous andalusite-staurolite-biotite rocks. These rocks contain euhedral twinned staurolite crystals up to 3 centimetres long, garnet averaging 1 centimetre across and erratic black tourmaline. Most of the large andalusite crystals have been altered to chlorite, biotite and sericite (Assessment Report 12642).

In the 1980’s and early 1990‘s, the area was explored as the Blaze and BPEX claims by Beau Pre Explorations as apart of the Valentine Mountain (MINFILE 0982B 108) property. In 1997, the area was prospected as the RB 3 claim.
