The Manson River East occurrence is exposed in a roadcut on a logging road 0.75 kilometre east of the Manson River and 5.5 kilometres northeast of the mouth of Munro Creek (Open File 1988-12).

The area lies within the Omineca Crystalline Belt, which consists of siliciclastic sediments with minor carbonates and mafic rocks. These rocks belong to the late Proterozoic Ingenika Group. Within the Wolverine Range, the sediments are highly metamorphosed and subsequently intruded by granodioritic bodies and associated pegmatites, which are most likely Early Tertiary. The Proterozoic Wolverine Complex rocks consist of amphibolite and calcsilicate gneiss, schists, micaceous quartzite, and crystalline limestone.

Mineralization consists of disseminated chalcopyrite and pyrite hosted by amphibolite gneisses of the Proterozoic Wolverine Complex. The amphibolite gneiss is interlayered with a hornblende- bearing granitic gneiss, with layers 10 to 30 centimetres thick. The interlayered gneisses are cut by quartz feldspar pegmatites up to 2 metres in width and intruded by granodiorite dikes and sills. These intrusions comprise up to 50 to 75 per cent of the total exposure. Later work indicated that the mineralization consists of chalcopyrite, pyrrhotite and scheelite exposed as ragged masses associated within the ultramafic enclave and its hornblende quartz monzonite host.

A grab sample analysed 0.12 per cent copper and 3 grams per tonne silver (Open File 1988-12).

In 1988, Chevron Minerals Ltd. conducted a geochemical sampling program in the Manson River East area, within the Will #2 grid east of the Manson river. Rock sample UG-7823 of aegirine-augite monzodiorite returned 0.13 per cent rare earth elements, sample UG-7813 of the alteration zone returned 0.50 per cent rare earth elements and sample UG-7816 of ‘rare earth dike’ returned the maximum value of 0.80 per cent rare earth elements (Assessment Report 17872).

In 2007, two grab samples (148669 and 148670) of monzonite or diorite with sulphide blobs assayed up to 0.748 per cent copper, 9 grams per tonne silver and 0.092 per cent tungsten (Assessment Report 29693; Breaks, F.W. (2009-11-10): Geological Report on the Mount Bisson Rare-Earth Element Claim Group).

During 2006 through 2011, Paget Minerals completed programs rock and silt sampling, geological mapping and a combined airborne magnetic and radiometric survey, totalling 564.4 line-kilometres, on the area as the Mount Bisson property

In 2014, a minor program of prospecting and soil sampling was completed on the area as the Wolverine Copper claims. Some of the assayed soil samples yielded anomalous values of silver, copper, and zinc.
