The preliminary estimates were based on 39 diamond core holes for the McFaulds 3 deposit
totalling 12,114 metres in length and on 15 diamond core holes for the McFaulds 1 deposit
totalling 4,715 metres in length.
At a cut-off grade of 1.5% Cu, Indicated resources at the McFaulds 3 deposit are estimated to
total 802,000 tonnes grading 3.75% Cu and 1.1% Zn. At the McFaulds 1 deposit, Inferred
resources are estimated at 279,000 tonnes grading 2.13% Cu and 0.58% Zn.
A set of cross sections and plan views were interpreted for both deposits to construct threedimensional
wireframe models at a cut-off grade of 1.5% Cu and a minimum true thickness of
two metres. These criteria reflect a potential underground mining scenario. High copper and zinc
grades were capped at 12.0% Cu and 8% Zn at McFaulds 3 and at 5% Cu and 7% Zn at
McFaulds 1 prior to compositing to 1.5 metres. Variogram parameters were interpreted from the
composited assay values. Block model copper and zinc grades within the wireframe models were
estimated by ordinary Kriging for the McFaulds 3 deposit and by inverse distance squared for
the McFaulds 1 deposit. Classification into the Indicated and Inferred categories was guided by
the drill hole density, interpreted variogram ranges, the apparent continuity of the mineralized
zones, and by available density determinations.
