The Cheryl occurrence is located 30 kilometres southwest of Nanaimo at the headwaters of Chemainus River on Mount Whymper.

The area, within the Cowichan uplift, is underlain by Mississippian to Pennsylvannian Fourth Lake Formation (Buttle Lake Group) sediments and Upper Triassic Karmutsen Formation (Vancouver Group) volcanic rocks whcih have been intruded by dioritic to granodioritic rocks of the Early to Middle Jurassic Island Plutonic Suite.

Outcrops on the claim host pyrite and chalcopyrite mineralization. Magnetite was observed in silt samples. A silicified chert and turbidite outcrop (OC4), hosts a quartz vein 1.5 metres long and up to 0.3 metres wide. Mineralization increases close to the vein but it appears that the wallrock contains more mineralization than the vein. Small shear zones with limonitic staining were also noted.

In 1981, New Gold Inc. completed a program of geological mapping and prospecting in the area as the Sherk and Widow claims. In 1984 and 1985, Imperial Metals Corp. completed programs of soil sampling and a ground electromagnetic survey on the area as the Whymp 1-2 claims. In 1988, the area was prospected and rock sampled as the Cheryl claim. A sample of outcrop (RS-15) containing 5 to 10 per cent pyrite and 3 to 5 per cent chalcopyrite assayed 0.14 grams per tonne gold and 9.6 grams per tonne silver (Assessment Report 18598).

In 1990 and 1994, New Gold Inc. completed programs of geological mapping and a ground geophysical surveys on the area as the Widow 3-8 claims. In 2008, Cuda Capital Corp. completed a program of helicopter-borne magnetic and VTEM surveys on the area as apart of the El Capitan Property.
