(a) 2PGE=Pt+Pd
Of particular interest in Table I is the 12-meter footwall massive sulphide intercept grading 1.21% Cu, 1.06% Ni, 0.143% Co, 3.74 g/t Pd and 0.31 g/t Pt encountered in hole 05-220. This intercept correlates well with the massive sulphides found in holes 04-181 and 04-195 drilled during the 2004 exploration campaign in the same area (Table I). This style of mineralization is characterized by higher grade base and precious metals (palladium plus platinum: 2PGE=4.05 g/t), content which is open to expansion.

(a) 2PGE=Pt+Pd
To date, eight delineation drill holes have been completed in the "Pit Area" and main sulphide lens(es) assays for six holes have been received (Table II). Highlights include holes 05-218 and 05-219. Results for all PGE low-sulphide intercepts for the eight holes are pending.
Two drills are presently "infill drilling" between the 119 Zone and the West Zone as Phase One Exploration continues.
True thicknesses of the footwall-style mineralization are not yet known. Details concerning drill core sampling, sample preparation, accredited laboratory geochemical and assay analytical methods, QC and QA procedures can be referred to in detail in Press Release No. SRU-07-04, June 10, 2004, page 3.
