The Hartley layered mafic igneous complex within the Great Dyke of
Zimbabwe contains economically-recoverable quantities of platinum
group metals and gold, nickel, copper and cobalt. The recoverable metals
are concentrated in a thin gently-dipping stratigraphic unit - the Main
Sulphide Zone. The Hartley Platinum mine, jointly owned by BHP and Delta Gold NL,
is scheduled to come on stream at the end of 1996 at an initial mining rate
of 2.16 million tonnes per annum and will produce approximately
150 000 oz of platinum and 3300 tonnes per annum of nickel, as well as
saleable amounts of palladium (110 000 oz), rhodium (11 500 oz) and
copper (2232 tonnes).
