Magnetics, IP, and drilling to date indicate the sulphides are restricted to the 100 metre-wide east-plunging gabbroic plug.

The 60 metre thick 1.1% Ni zone would have to extend for 600 metres along strike to the east giving it about 8 million tons before an economic open-pit plan could be considered to pre-strip the 66 metres of overlying rock. If the zone plunges as indicated it would soon be below open-pittable depth!

The 2.3 m thick 9% nickel horizon would have to extend for over a kilometer along strike to justify development of an underground high-cost room-and-pillar operation.

Now it depends on whether the sulphides increase in thickness or grade to the east, for at the present indicated grades, thicknesses, and depths both surface and underground mining scenarios are uneconomic!
