Old pyrite quarry located 3.5 km NNE of Nairne (Brukunga), now used as a training place for the fire brigade.
Cambrian pyrite beds at the base of the Kanmantoo Group (quartzites, greywackes, siltstones).
The mineralization has a sedimentary origin and was affected by a remobilization during amphibolite facies metamorphism.
Tension Gash Veins, perpendicular to fold axis and mineral lineation are mineralized with manganochromite, hexagonal and monoclinic pyrrhotite, nickel, graphite, apatite, REE phosphates (Ca-Th-Ce phosphate and lanthanide phosphate) and a PdSb2 mineral.
The mineralization also contains hyalophane and barium micas.
"PIRSA is currently responsible for managing the former Brukunga pyrite mine site and investigating different remedial options aimed at achieving an environmentally sustainable solution to acid metalliferous drainage generated from the waste rocks and tailings." (MESA Journal 61 (2011) p. 25).
