Currently (2008) owned by the Doe-Run Company. This mine is famous for its large gray scalenohedral calcite crystals, many showing phantom crystals, sprinkled with a combination mix of chalcopyrite/marcasite. Also has rarely produced wonderful spinel-law galena crystals.

Recent drilling has encountered economic mineralization within the lower Bonneterre Dolomite of the Brushy Creek mine, more than 30 m below the main ore-bearing horizon of the district. These ores are more zinc and copper rich than typical deposits (Zn/Pb commonly >2 and Cu up to 8 wt %), with notable enrichments in Ni, Co, and Ag. There is pronounced zoning of Ni-Co, Cu, Zn, and Pb with increasing distance above the underlying Lamotte Sandstone. The stratigraphic position, massive character, metal contents, mineral zoning and textures, and gangue dolomite cements of the orebody are unusual for the Viburnum Trend. Mineralogically and stratigraphically, these ores are more similar to the historically mined ores of the Indian Creek and Fredericktown-Mine La Motte districts to the north and east of the Viburnum Trend.
