The Peanut showing is located "south of Cultus Creek and about 3.5 kilometres west of Mount Burnett" (Minister of Mines Annual Report 1968). It is described as a shear zone cutting altered granite (alteration not described). The shear zone strikes 325 degrees and dips 75 degrees southerly; it contains a narrow lens of vein material (assumed to be quartz) which carries tetrahedrite. The vein, which is only 10 centimetres wide, has been traced for 12 metres on surface and to a depth of 8 metres in an inclined shaft. Although no granite is mapped in the area of the claims, there could be a small stock, possibly related to the Middle Jurassic Nelson intrusions, too small to show at the regional scale.
