Capsule Geology

The Ron occurrence is located on a northeast facing slope in the southern headwaters of a north flowing tributary of Sidenius Creek, in the Muskwa Ranges.

Regionally, a Lower and Middle Devonian platformal carbonate sequence consists of two assemblages. The lower assemblage comprises the Upper Silurian(?) and Lower Devonian Muncho-McConnell and Lower and Middle(?) Devonian Stone formations, which consist almost entirely of dolomite with various admixtures of quartz sand or sandstones and argillaceous dolomite. The upper assemblage, comprising the Middle Devonian Dunedin Formation, consists of dolomites or variably dolomitized limestones. The Lower and Middle Devonian sequence lies disconformably on Lower Silurian carbonates of the Nonda Formation and is overlain by basinal shales of the Upper Devonian-Lower Carboniferous Besa River Formation.

It is assumed that the host stratigraphy of the Ron occurrence is similar to the Robb Lake deposit (MINFILE 094B 005), located approximately 7 kilometres to the south, where lead-zinc mineralization in dolomite breccias is distributed along the western flank of a large, southeast plunging anticline made up of Muncho-McConnell and Stone formations dolomites (the Ron showing, however, appears to be on the eastern flank of the anticline). The lead-zinc showings are situated very close to the depositional edge of the carbonate platform.

Locally, finely crystalline sphalerite and slightly coarser galena occurring in a brecciated horizon of medium to thick-bedded dolomite with argillaceous and sandy dolomite interbeds.

Work History

In 1973, Buckhorn Mines soil sampled the area as the Ron claims.
