The relatively high grade of the 2.3 metre horizon and the underlying wide granite dykes point to a remobilized sulphide melt along a zone of weakness or fracture.

Binocular microscope work will show the shape and size of the individual pyrrhotite, pentlandite (Ni), chalcopyrite (Cu), and other sulphide grains, and thin-section work will show the growth-shapes of all the constituents in the rock.

However indications of either precipitation from a differentiating melt or secondary re-crystallization are difficult to determine, especially if the rock cyrstallized at depth.

The high Nickel grade (10%) is unknown in layered ultramafic complexes around that I am aware of!

Taking this all into account, the sulphide horizon could still be large, rich, and economic!!
