Brumell, the surface exposures, mag anomalies, and drill intersecting show the gabbro is a relatively small 120 metre wide plug. There would not have been enough nickel in the 120 metre gabbro-norite melt to give the higher grades and widths at the base of the plug. Perhaps the pyrrhotite-nickel-sulphide-enriched norite-gabbro rock in the plug was originally a melt forced out of a large differentiating ultramafic intrusive below or alongside Lac Rocher to fill a fracture zone above or alongside the intrusive, and then this melt differentiated within the small 120 metre wide plug to produce the lightly disseminated .5% nickel upper portion of the plug exposed on surface, the strongly disseminated 1% nickel lower portion, and the massive 8% nickel bed. Perhaps others have an idea how the large amount of sulphides could have differentiated from such a narrow plug??
