A molybdenum anomaly was found by soil sampling on the southeast portion of the ME4 claim, just above a small lake at the head of an east-flowing tributary at the headwaters of the west branch of Hellroaring Creek.

The area is underlain by quartzites and grits of the Cranbrook Formation (Lower Cambrian Gog Group), intruded by a small stock of Mesozoic granodiorite, likely of Early Cretaceous age. Contact metamorphic effects peripheral to this medium-grained intrusion appear to be minimal, but the rocks are metamorphosed to biotite facies regionally. Molybdenite mineralization was not located in place but is assumed to be present. Pyrite and pyrrhotite occur as disseminations up to 10 per cent by volume in the Cranbrook Formation, which is marked by a prominent gossan.
