Jurassic Hazelton Group volcanics are intruded by an Eocene or older monzonite stock that varies from 150 to 350 metres in width and appears to be continuous in a north-south direction for about 6 kilometres. The volcanic rocks vary in composition from lithic and crystal lithic tuffs to Lower Jurassic Hazelton Group breccias and andesitic flows of the Unuk River Formation. Regional metamorphism is of lower greenschist facies with significant epidotization in the andesites, agglomerates and flow breccias west of the intrusive.

The intrusive is comprised of a light green, fine to medium-grained monzonite that hosts widespread copper mineralization in the form of chalcopyrite, malachite and auzurite. Refer to the Mt. Dunn property (VV (Mt. Dunn) 104K 079).

Significant sphalerite was found peripheral to the monzonite porphyry within altered pyroclastic breccia north of the VV (Mt. Dunn). Mineralization consisted of dark brown, iron-rich sphalerite within well crystallized quartz and quartz-calcite veinlets cutting pyroclastic breccia. The sphalerite-bearing veinlets range up to a few centimetres in width over an area of about 61 by 30 metres. In 1976, the overall grade was reported as less than 0.1 per cent zinc (Assessment Report 6234, page 20). Honey brown siderite is frequently associated with the zinc mineralization.

The showing lies northwest of the intrusive within intermediate volcanics that shows advanced degrees of propylitization culminating into advanced epidotization and chloritization in scattered locations. The propylitization is thought to be representative of both regional greenschist facies metamorphism and local hydrothermal alteration.

The sphalerite mineralization is located within a north trending fault gully close to a cross-cutting hornblende diorite dike. The mineralization is underlain by a thin barren-carbonate horizon which probably provided a favourable chemical environment. The sphalerite is present only in quartz, plus or minus, calcite veinlets.

The Eric 2 was covered by an airborne geophysical survey completed in 2013 and 2016 by Metalis Resources.
