The Black Knight occurrence is located within the lower reaches of East Georgie River approximately 3 kilometres upstream from its mouth on the Portland Canal. It is situated 25 kilometres south (192°) of Stewart, B.C.

Regionally, the area lies adjacent to and includes moderately folded volcanic and sedimentary rocks of the Lower Jurassic Hazelton Group intruded by a succession of plutons of the Eocene Coast Plutonic Complex. Hazelton Group rocks include a variety of sandstones, conglomerates and breccias as well as minor intercalated tuffs, siltstones and flow material. Granodiorite is the dominant rock of the Coast Plutonic Complex but stocks and plutons vary from quartz monzonite, quartz diorite to granite. Numerous dike swarms range in composition from granite, quartz monzonite, granodiorite and quartz diorite.

The Black Knight property is underlain by an assemblage of epiclastic rocks of the Hazelton Group intruded by massive granodiorite and related dikes of the Coast Plutonic Complex. The epiclastic rocks have been locally subjected to strong shearing movements and are generally altered to a chloritic foliated rock.

Mineralization appears to be related to a shear zone where a quartz vein 1.32 metres wide has been developed by limited historic underground work and opencuts. The quartz vein is mineralized with galena, sphalerite, pyrite and chalcopyrite. A grab sample of nearly solid galena and sphalerite with little gangue assayed 43 per cent lead, 28 per cent zinc and 562.19 grams per tonne silver (Minister of Mines Annual Report 1906).

In 1910, development work consisted of 84 metres of underground work and a large number of opencuts and prospect shafts.

Granby Gold Inc. conducted airborne magnetometer and gamma ray spectrometry surveys (and geological interpretation of the same) over their East Georgie River project area, including the Black Knight showing, from 2017 to 2020.
