Typical Cross Section of Babbitt.

Higher grade (>1% Cu) occurs near the basal contact of the meta-sediments, while much of the high grade semi-massive sulphide is found in the adjacent hornfelsed sediments or is spatially associated with the hornfels.

Disseminated sulphides (2 to 5%) are also found in troctolites and norites around the semi-massive ores. Sulphide contents decrease above the basal zone, but increase again in the "Cloud Zones".
