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 the east to justify development of an underground high-cost room-and-pillar operation.

Although the east extensions are untested it appears that if the present grades and thicknesses do not continue for up to a kilometre to the east, or if the grades and thicknesses do not increase without the plunge continuing to the east, that both the open-pit and underground mining scenarios are uneconomic!
