The Bonbon occurrence is located at an elevation of approximately 550 metres, west of Solly Creek and approximately 5 kilometres southwest of Mount Brenton.

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 wide, occur within cherts of the Fourth Lake Formation. Also, disseminated pyrite occurs within greywacke and sandstone, as identified by drilling.

Work History

In 1984, the Bonbon claims were staked by L. Specogna. In 1985 and 1987, trenching and minor winkie drilling of the showing was completed. In 1986, Abermin Corp. and Laramide Resources conducted a program of geological mapping, trenching, rock sampling and diamond drilling to continue testing the Coronation Zone (MINFILE 092B 129) and other reconnaissance targets on the Lara property including the Bonbon occurrence area. In 1990, two diamond drill holes, totalling 21.9 metres, were completed.

In 2023 and 2024, Nova Pacific Metals Corp. conducted a three-dimensional interpretation of a previous completed airborne magnetic survey on the Coronation trend of the Lara property, including the Bonbon occurrence area.
