In lot 10, concession V, Foster Township, cobaltite, pyrrhotite, and chalcopyrite occur near the contact between a partly altered Nipissing-type gabbro body and hornfelsed calcareous siltstones of the Espanola Formation. The sulphides are in, and close to an east-west-trending quartz-carbonate vein which is as much as 40 feet (12 m) wide and can be traced for several hundred feet (metres). An equally large north-trending vein barren of sulphides is exposed to the north. Pyrrhotite and chalcopyrite are found mainly within the quartz-carbonate vein whereas cobaltite occurs as euhedral crystals up to 1 inch (2.5 cm) in diameter in actinolite amphibolite along the walls of the vein. Both calcite and brown-weathering ankerite are present in the vein.

Stripping, trenching, and diamond drilling has been carried out on the occurrence. An adit 100 feet (30 m) long has been driven into a hill underlain by metagabbro.

Dolomite
Formula: CaMg(CO3)2
Reference: Ontario Division of Mines, Map 2311, Merrit and Foster Townships Sudbury District 1974
Erythrite
Formula: Co3(AsO4)2 · 8H2O
Habit: Acicular
Colour: pink
Description: Pavel Kartashov did some microprobe work on what was thought to be Erythrite in 2011 but it turned out to be cobalt-bearing scorodite. Subsequently in 2012 Reiner Mielke found another pink mineral in acicular crystals that gave a positive HCL test for cobalt ( bright blue in Conc. HCl). This new material differed from the material Pavel tested. The material Pavel tested was granular and produced a yellow solution in conc. HCL.
