 The ultramafic body is in the form of a 'keel', with a southward plunging folded surface pinching out the northern end of the resource, where it enters a heterogeneously sheared structure.The ultramafic sequence is folded at its down-dip termination, where it enters a shear, with remobilised sulfides forming a discontinuous remobilised stringer ore zone of low grade.A proposed 'shelf fault' terminates the down dip portion of the ultramafic in the south of the MAggie Hays portion of the CUU, however it is equally likely that a porpoising hinge to the syncline could equally well explain the apparent truncation of the depth of the orebody in the south.
