Mining explosives supplier Bulk Mining Explosives (BME) director Tony Rorke told Mining Weekly that unless South Africa makes a serious investment towards improving their blasting training, millions of rands per year will continue to be wasted in lost productivity.

...intensive investment in training and the use of new blasting technologies are needed if opencast mining operators are to take full advantage of the booming commodities market over the next few years. Effective blasting, probably the most crucial aspect of opencast mining, is largely being neglected as operators, accustomed to the results they are getting, do not examine the opportunities available to them to increase their outputs.

The Company recorded first quarter earnings of $168 million or $0.88 per share (basic) compared to earnings of $55 million or $0.55 per share for the previous year.

These factors were partially offset by lower sales volumes at Robinson and Carlota. Adjusted earnings for the first quarter totalled $51.8 million or $0.27 per share (basic) compared to $55.3 million or $0.56 per share (basic) for the previous year.

GFMS, in its recently-published "Platinum & Palladium Survey 2011", is forecasting that platinum will sustain a gross surplus in 2011 of a similar magnitude to that of 2010. Mine production is expected to increase modestly this year, and while GFMS describes the situation in South Africa as "challenging", including risks surrounding this year's wage negotiations, the prospect of a repetition of the major disruptions of 2007 and 2008 is relatively low. The prospect of relatively buoyant prices also underpins increased supply from recycling and GFMS doubts that fabrication demand this year and keep pace with supply, let alone exceed it.
