Nickel? Copper?

Yes, a BIG HIT and only more big hits are coming
From the Aug. 11, 2009 news release:
Drilling Campaigns Show Nickel Mineralization over Significant Widths
MacDonald's drilling campaigns in 2007 and 2008 did intersect low-grade nickel mineralization over significant widths in several locations on the McNugget Property. Ultramafic rocks have been intersected and by interpretation this would indicate a potential to host both nickel/copper and chrome mineralization. Hole MN07-39 intersected 0.36% Ni over 4.5 metres and 0.26% nickel over 27 metres in a gabbro unit. Hole MN07-46 encountered peridotite throughout its entire 170 metre length and assayed 0.18% Ni over 112 metres, including 0.20% Ni over 41 metres in an ultramafic volcanic sequence which indicates that the base of the geological sequence is present on MacDonald's property.
So they found nickel on the McNugget property albeit not ineconomic quantities.
Now this from the May 31 NR:
Mr. Butler notes, "Regionally, McNugget has three VMS mineralized greenstone fold limbs (to the north, west and southeast - likely the same stratigraphic suite) all of which have now yielded VMS mineralization over a potential cumulative strike length of approximately 20 km. A new VMS camp with characteristics similar to those seen at Matagami or Noranda in Quebec is now conceivable (i.e., larger VMS deposits with satellite deposits along strike)."
On the north fold limb, a fence of 5 new diamond drill holes has intercepted Cu-rich VMS along a strike length of approx. 1 km (still open along strike and to depth) with preliminary assays of greater than 1% Cu. Drill hole MN-10-90 had a greater than 4.5m intersection with a greater than 1% Cu zone, and drill hole MN10-102 a 15m greater than 1% Cu zone (1% is the limit of the preliminary assay technique used). This greater than 1 km zone also has strong zinc (Zn) values.
A second VMS target at the nose of the north and west fold limbs appears to be a plunging Zn-Cu-rich VMS body. Drill hole MN10-104 cut spectacular 10cm wide bands of sphalerite (Zn sulphide) throughout a 30m wide massive sulphide horizon. Drill hole MN10-112 (assays pending) was drilled along strike and at a greater depth to the east (approximately 100m) on this body. Field analysis of drill core suggests a potential VMS feeder zone in the vicinity.
So now they have found copper and zinc on the McNugget property but no Nickel. Help me I'm confused.
