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 (ca. 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 (2.54 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 (ca. 30 m) long has been driven into a hill underlain by metagabbro.

Locality descriptionIdentification: Visual Identification
β“˜ Calcite
Formula: CaCO3
β“˜ Chalcopyrite
Formula: CuFeS2
β“˜ Cobaltite
Formula: CoAsS
Habit: cubic crystals ( up to 3.0 cm) and more rarely cubo-pyritohedral crystals
Description: Many specimens found in a zone at the contact between a large quartz vein and gabbro host rock. The quartz vein is up to 15m wide has a vertical dip and strikes North. The contact zone varies in width and consists of mainly grey coarse grained iron rich dolomite with lesser amounts of actinolite, fine grained calcite, talc (fine to coarse grained), pyrrhotite, pyrite, chalcopyrite and quartz. Cobaltite occurs mainly in the grey dolomite but is also found abundantly in a mixture of coarse actinolite and fine grained calcite and occasionally in massive pyrrhotite, and rarely in quartz.
β“˜ Copiapite
Formula: Fe2+Fe3+4(SO4)6(OH)2 · 20H2O
β“˜ Dolomite
Formula: CaMg(CO3)2
β“˜ 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.
β“˜ Marcasite
Formula: FeS2
β“˜ Pharmacosiderite
Formula: KFe3+4(AsO4)3(OH)4 · 6-7H2O

β“˜ Rozenite
Formula: FeSO4 · 4H2O
β“˜ Scorodite
Formula: Fe3+AsO4 · 2H2O
Description: Two different varieties of scorodite were observed - brown massive pseudomorphoses after cobaltite and pink Co-bearing (~1 % CoO) crystalline spherulites and crusts around brown pseudomorphoses.
