The Rye occurrence is located approximately 107 kilometres east of Dease Lake and about 11 kilometres south of the Turnagain River.

The area of the showing is mapped as Ingenika Group undivided sediments and metasediments consisting of the Upper Proterozoic Swannell and Tsaydiz formations. In the Rye area, these comprise quartzite, shale, siltstone and pebble conglomerate with minor overlying limestone and dolomites. The northeastern contact of the Early Cretaceous Cassiar batholith occurs a few kilometres to the east. The batholith varies in composition from granite to quartz monzonite to granodiorite.

Scheelite occurs as disseminations which are distributed fairly uniformly throughout a 90 to 100 centimetre thick altered bed. The original rock, possibly a sandstone, has been silicified and is often banded with chlorite; it exhibits gneissic texture in some samples. Part of the bed carries a bladed mineral, possibly tremolite. The bed is exposed for about 30 metres in three outcrops. Three channel samples yielded 1.25 per cent WO3 over 1 metre; 0.54 per cent over 0.9 metre; and 0.40 per cent over 1 metre (Assessment Report 3213).

In 1971, Conwest Exploration conducted geological and geochemical surveys and collected 214 soil and 9 channel samples.
