Abstract
Hole WC99-01 intersected a mafic to ultramafic intrusive complex consisting of massive, undeformed gabbro, pyroxenite, peridotite and serpentinized peridotite intruding granitic pegmatite. Representative samples of all rocks types were sent for assay and returned <5 ppb Pd, <5 ppm Pt, 1-79 ppm Cu and 10-1580 ppm Ni. The highest Ni concentrations were found in strongly serpentinized peridotites with 20-25 % magnetite. The serpentinized peridotites which were intersected in drill hole WC99-01, are interpreted to be the cause of the strongest part of the central magnetic and IP anomalies.
