Jan 21, 2020 South Africa’s reef deposits, especially gold and platinum-bearing ore bodies, are narrow and tabular. While legislation dictates a minimum operation height of 800 mm in areas where people work, some of the country’s narrow reef mines have ore bodies with thicknesses of less than 500 mm, which results in ore dilution, as waste ore with zero economic value is also mined.

Unusually large deposits ( 200Mt as suggested mining rate would be unobtainable) Very deep, flat ore bodies (production limited by hoisting limits of shaft) Steeply dipping tabular or massive deposits that are worked in steps towards great depths (limited to rate of deepening of the working, use Tatman (2001)).
