The Herbert occurrence is located on the western side of Herbert Inlet, approximately 2.5 kilometres north of Gibson Cove.

The area is underlain by granodiorite of the Early to Middle Jurassic Island Plutonic Suite.

Locally, a quartz vein, up to 60 centimetres wide with nearby smaller veins, cuts granodiorite. The vein contains up to 5 per cent chalcopyrite with abundant malachite. In 1987, a 2 metre chip sample contained 0.48 per cent copper and 0.02 grams per tonne gold; while individual rock samples (18271) yielded up to 1.26 per cent copper (Assessment Report 16224, page 29 and Figure 6).

During 1984 through 1987, Consort Energy completed a program of prospecting, geological mapping and rock, silt and soil sampling on the area as the Lazeo-Klein and Herb claims.
