Location and accuracy The Ridge Top mine (Hawley and Associates, 1978, mineral deposit C) is at an elevation of about 3150 feet. The mine is on the crest of the divide between Little Moose Creek and locally named Lucky Creek (MM017). The location is accurate within 500 feet.

Geologic setting

Geologic description

The Ridge Top mine is in quartz-feldspar schist and gneiss in the hanging wall of a layer of quartzite. The quartzite is a unit of the upper Precambrian Birch Creek Schist (Hawley and Associates, 1978, fig. 4.1-A(2); Bundtzen, 1981). The deposit at the Ridge Top mine is geologically similar to the one at the Upper Ridge mine (MM141), which consists of partly oxidized, slightly auriferous, stibnite-bearing quartz veins that also cut Birch Creek quartzite.

Mineral deposit model Simple Sb deposit (Cox and Singer, 1986; model 27d).
Mineral deposit model number 27d
Age of mineralization Probably Eocene (see records MM091, MM144, and MM141).
Alteration of deposit Oxidation of iron and antimony minerals (?).

Production and reserves

Workings or exploration Surface cuts.
Indication of production Yes; small
Production notes Production from the Ridge Top mine is probably included with that from the Stampede mine (MM144).

Additional comments

The Ridge Top mine is on patented mining claims that are part of the Stampede property.
