The Eric occurrence is located about 1.3 kilometres east of the AL (Thesis II/III) past producer (094E 091) approximately 295 kilometres north of Smithers.

The Eric zone is located along the Bonanza fault system, about 980 metres south of the Bonanza deposit (094E 079). The area is underlain by andesitic volcanic rock of the Lower Jurassic Toodoggone Formation (Hazelton Group). The Adoogacho and Metsantan members comprise the Toodoggone Formation in this area. The Adoogacho Member consists of trachydacite ash-flow tuff with lenses of lapilli tuff, rare marlstone, and conglomerate near the base. The Metsantan Member is composed mainly of trachyandesite (latite) flows with lenses of lapilli tuff, and lahar; minor volcanic sandstone and conglomerate (Bulletin 86). The Metsantan Member, in part, directly overlies the basal Adoogacho Member and is also in fault contact with it.

Trench TA88-19, at the south end of the Eric zone, yielded a mineralized interval of 5.25 grams per tonne gold over 13 metres (Bowen, 2012). Drillholes 88-39 to 41 tested the Eric zone directly below this trench. Broken ground resulted in holes 88-39 and 40 being terminated prematurely. Hole 88-39, the shallower of the two holes, entered the pyrite plus/minus chalcopyrite-bearing siliceous hostrock at about 11 metres and was terminated at a depth of 17.1 metres. Low-grade gold values, from 0.60 to 1.55 grams per tonne, were encountered in this interval (Bowen, 2012). Hole 88-40 yielded no significant values, nor did hole 88-41, which successfully penetrated through the siliceous hostrock at a vertical depth of about 50 metres below surface. It is thought possible that holes 88-40 and 41 were drilled beneath a south plunging mineralized shoot which was encountered in the surface trench and hole 88-39.

About 200 metres east of the Eric zone is the Gosselin zone, where blebs of barite have been found associated with silica-altered rock, however, surface gold values in trenches have been found to be low. The Gosselin zone is probably a left-lateral offset segment of the Bonanza structure.

In 1988, three NQ diamond-drill holes totalling 145 metres were drilled on the Eric zone by Energex Minerals Ltd.

See Bonanza (094E 079) for details of the Ranch (Al) property which contains the Eric showing and discusses the work done on it.
