Dec 07, 2005 (P Beach) - Hematite exposed in trenches within a ferruginous carbonate unit, 40 feet thick, which strikes NNE and dips 15 to 30 W. Overlain by conglomerate and underlain by ferruginous shale of Huronian age.

May 04, 2011 (A Wilson) - Trenching resulted in the discovery of a hematite occurrence within a 10 to 15 m (30 to 50 ft) thick dolomite bed which is overlain by red quartzite cobble conglomerates, and underlain by red shales of probable Paleozoic age. The carbonate bed consists of relatively pure yellowish-green dolomite. It strikes N10°E and dips 18°W and is exposed only in the trenches.
