Capsule Geology

The Wonderland (Cottonwood) showing is located approximately 800 metres west of Widow Creek at an elevation of 792 metres.

The area is underlain by sedimentary rocks of the Mississippian to Pennsylvanian Fourth Lake Formation, Buttle Lake Group. The manganese minerals are hosted in the Lower Mississippian Shaw Creek Member (dated by conodonts, Personal Communication - Nick Massey, 1991).

Rhodonite and rhodo-chrosite lenses occur parallel to bedding in cherty tuffs. They occur over an area about 30 metres north-south by 15 metres east-west. The lenses are coated with oxides. Rhodochrosite in small amounts occurs in irregular masses that grade into rhodonite.

The showing was discovered in 1919 and staked as the Sentinel, Wonderland and Wonderland No. 2 claims. From 1985 through 1989, BHP-Utah Mines completed programs of geochemical sampling, geological mapping and ground and airborne geophysical surveys in the area as the Striker Property.
