The most recent Drill Results for Copper Hill Resources.
Copper Hill's wholly owned subsidiary, Copper Hill Resources Inc.(collectively Copper Hill), and its exploration partner, Billiton Resources Canada Inc., have successfully completed a 10-hole, 1,110-metre diamond
drill program at their Powderhorn Lake VMS exploration project.
The Powderhorn Lake project is situated in the Buchans-Robert's Arm belt, in central Newfoundland, 40 kilometres to the northeast of the Buchans group of deposits which together produced 17.8 million tons of ore grading 14.88 per cent Zn, 7.7 per cent Pb, 1.3 per cent Cu, 88 grams per tonne Ag and 1.28 g/t Au. Copper Hill and Billiton believe that the Powderhorn property is prospective for the discovery of a new base metal deposit with open-pit potential.
Seven holes intersected stratiform sulphide mineralization hosted by Buchans group felsics. Based on numerous criteria including geochemistry, holes PH01-2 to PH01-4, collared to the north of the exploration grid, did not pass through the overlying Shoal Arm formation to intersect the underlying and presumed north-dipping, Buchans group felsics. The sulphides encountered here are of sedimentary origin and included sections with between 10 per cent and 25 per cent total sulphides, comprising magnetic and non-magnetic pyrrhotite, with pyrite, and minor sphalerite and chalcopyrite.
Hole PH01-3 intersected a small showing of globular, magmatic pyrrhotite, hosted by an autobrecciated phase of a composite mafic dike-like assemblage. The similarity of this mineralization and setting to that
previously discovered to the south may have future economic ramifications.
Zn-Cu-Au-Ag mineralization
Six holes, PH01-5 to PH01-10, intersected promising base metal sulphide mineralization along multiple (stratiform) horizons within a felsic tuff sequence interpreted to be part of the Buchans/Roberts Arm group. The mineralized horizons are open in all directions and contain untested IP targets with favourable signatures awaiting phase 3 drill hole testing. The most significant results, with weighted averages, are tabulated below:

Boreholes PH01-5, 6 and 8 returned numerous other similar grade intersections over narrower width and all holes ended in the mineralized zone.
In spite of evidence supporting (local) mobilization of sulphides, the preservation of metal zoning which appears to occur in both a lateral and vertical (stratigraphic) sense, attests to the volcanogenic origin of the precursor body of mineralization. The metal zoning involves both a zinc-rich (with Pb) and a copper/gold/silver-rich component or facies as is
evident from the abbreviated results tabled. Zoning of this nature within felsic volcanics/volcanoclastics is known to characterize VMS camps worldwide.
Copper Hill wishes to thank the Junior Company Exploration Assistance Program (JCEAP) as this drill program was partially financed by this program which is administered by the Newfoundland and Labrador Department
of Mines and Energy.
