At the end of mining in 1975 the 2.5 kilometre length of mineralisation partially drilled and mined was reported to contain resources totalling 4,875,000 tonnes. This was estimated to have an average grade of around 16 grams per tonne (g/t) Platinum equivalent (2,800,000 ounces). Estimates of grades from several studies were in excess of 10 g/t platinum plus palladium with a ratio of 40:60 (Pt:Pd). Particular areas had averages of up to 16.5 g/t platinum plus palladium.
