The Crash prospect consists of two siliceous, cataclastic breccias similar to those that host the mineralization at the Dahl prospect (MG053). The Crash zone is in a splay structure associated with a regional fault that hosts the Dahl prospect (MG053). The mineralization in one shale-hosted breccia zone contains massive chalcopyrite and sphalerite with traces of galena. It is near the contact of the Lower Ordovician to Lower Silurian, Post River Formation and the Middle to Upper Silurian Terra Cotta Mountains Sandstone, both units of the Dillinger sub-terrane (Bundtzen, Harris, and Gilbert, 1997). The other cataclastic breccia contains abundant arsenopyrite. Both sulfide-bearing breccia zones are from 3 to 30 centimeters thick, appear stratiform or parallel to sedimentary bedding, and are isoclinally folded. This suggests the sulfides were formed prior to Lower Cretaceous compressive deformation (Bundtzen, Harris, and Gilbert, 1997). The mineralization at the Crash prospect might be related to younger plutons. Samples from the larger sulfide-bearing breccia contain up to 16.5 percent copper and 926.8 grams of silver per tonne. (Brewer and others, 1992). The smaller cataclastic zone has a pod 02 to 2.0 meters thick of massive arsenopyrite that contains 6.8 grams of gold per tonne. Three samples collected by Smith and Albanese (1985) contain up to 316 parts per million (ppm) copper, 86 ppm lead, 940 ppm zinc, and 10.5 grams of silver per tonne. The gold in the Crash is atypical of most sulfide occurrences and prospects in the Farewell Mineral Belt.
