The Kipahigan Ultramafic body is located 45 miles N-NW of Flin Flon, Manitoba. It crops out in the axial position of a large-scale F₂ fold and intrudes Nokomis garnet-biotite gneisses. The ultramafic body probably intruded before the first recognized period of deformation (F₁) and before the main metamorphic event (1600--1800 my).

The ultramafic rocks consist of almost completely uralitized pyroxenites and wehrlites with a minor amount of harzburgite present. The copper-nickel mineralization is concentrated mainly in the central portion and does not extend outside of the ultramafic body. The primary and secondary sulphide minerals present are pyrrhotite, chalcopyrite, pyrite pentlandite, violarite and marcasite, The sulphides are considered to have a magmatic origin, and a sulphide melt separated at an intermediate time during the crystallization of the magma.

A computer analysis of the chemical data shows that four factors are required to explain the variance in the garnet-biotite gneisses. The gneisses surrounding the Kipahigan Lake Ultramafic are not anomalous with respect to the amount of Cu, Ni, or Zn present.
