The Bonbon occurrence is located east of Solly Creek.
The area is underlain by sediments of the Mississippian to Pennsylvanian Fourth Lake Formation (previously the upper part of Muller's Myra Formation; Buttle Lake Group). The sediments consist of interbedded laminated chert, argillite and siltstone with beds of fine to coarse-grained tuff. The unit, particularly the cherty intervals, is locally cut by quartz veins and veinlets.
Locally, four arsenopyrite bearing calcite veins several centimetres in width occur within cherts of the Fourth Lake Formation. Also, disseminated pyrite occurs within greywacke and sandstone, as identified by drilling.
In 1984, the claims were staked by L. Specogna. In 1985 and 1987, trenching and minor winkie drilling of the showing was completed. In 1990, two diamond drill holes, totalling 21.9 metres, were completed.
