successful low-cost open-pit mining of the thick platreef ni-cu-pge deposit, coupled with rising costs and limited scope for mechanization associated with narrow reef-type deposits in the eastern and western bushveld, have driven efforts to locate similarly wide magmatic sulfide orebodies at surface or at reasonably shallow depths elsewhere in

the j-m reef, and other pge-enriched sulphide horizons in the stillwater complex, share many similarities with the highly prolific merensky and ug2 reefs in the bushveld complex. at the same time, the lower part of the stillwater complex also shows the potential for much larger scale disseminated and high-sulphide pge-ni-cu deposits, similar to
• stratiform chromititic deposits enriched in pges in the upper group 2 (ug2) reef of the bushveld complex. 1 in this study, pgm deposits include some combination of iridium, osmium, palladium, platinum, rhodium, and ruthenium in concentrations high enough to warrant exploration activity or recovery at current prices.
we mine 40% of the world's platinum metals at the bushveld complex in south africa & the unki mine in zimbabwe.. south africa, on the northwestern limb of the great bushveld mineral complex. 03. unki - our mechanised platinum mine on the great dyke of zimbabwe, with a
the mines of the platreef, on the north limb of the bushveld complex, are among the largest and most profitable in the world. led by the development of anglo american’s mogalakwena mines in the 1990s, the district has grown to include ivanhoe’s platreef mine and platinum group metals’ waterberg project, and now hosts over 400 million

summary seismic methods have become, and will continue to be, an important tool to help unravel structures hosting mineral deposits at great depth. this work demonstrates how the reflection seismic method (mainly 3d seismics) has been successfully used to explore some of the world’s largest platinum deposits and map the gross structural architecture that controlled the formation of these ore
the world’s pges are supplied from mining operations in south africa’s bushveld complex (johnson matthey, 2010). the bushveld complex has geographically distinct western and eastern portions. historically, the majority of supply has come from the western limb due to the favourable platinum grade distribution, geographical
the majority of platinum reserves worldwide are found in a deposit known as the merensky reef, located in the bushveld complex of south africa. estimated reserves for the merensky reef are 333 million troy ounces (anstett, 1980), with an average grade of 0.25 ounces per ton. a similar geologic occurrence can be found in the great dyke of
the western platinum mine is near rustenburg, south africa. the site was first discovered in 1924 by hans merensky, d. mckerrell & m. weber. the western platinum mine is a underground mining operation. initial production took place in 1971 and overall output was considered to be medium size. mine operations consist of underground workings.
the mines of the platreef, on the north limb of the bushveld complex, are among the largest and most profitable in the world. led by the development of anglo american's mogalakwena mines in the 1990s, the district has grown to include ivanhoe's platreef mine and platinum group metals' waterberg project, and now hosts over 400 million ounces of
