  Abstract An estimated 90 percent of South Africa s gold-bearing reefs are less than 1 m thick Joughin (1976). A large mineral resource therefore lies in seams that are becoming increasingly uneconomic to extract because of the grade dilution caused by raising the mining height to suit currently available mechanized mining equipment Harper (2008).
