IMPLATS’ PLATINUM OUNCES INTO THE FUTURE

Of this, 1.15 million ounces will still come from Implats’ mainstay, the Impala Platinum lease area in the western Bushveld near Rustenburg. That operation will remain at its steady state of production, with two major shaft sinking projects recently begun to replace older shafts nearing the end of their lives.

The 20 shaft, being sunk by Murray and Roberts Cementation, will be the last shaft in Impala’s main lease area to go down just over 1,000 metres; the others in the future will be deeper. The 20 shaft underwent its first blast for the main shaft sink in August 2005, with the pre-sink having been completed. The 20 shaft is at the northern end of Impala’s lease area next to the 12 North shaft, and it will produce 185,000 tonnes of reef a month. It will consist of a single large station below reef, with a decline system feeding upwards and another one feeding downwards. It is scheduled to begin its first production in 2007.

TJATE PROJECT GIVES JUBILEE BALANCE

Bird’s excitement about Madagascar almost threatens to overshadow Tjate, particularly following favourable results from geophysical work done on the company’s Lavatrafo property in the Londokomanana region located some 150 km north of Antananarivo. This has led to Jubilee commissioning a 2,000 metre drilling programme there.

 

The first borehole of that programme has intersected a x70 metre-wide multi-metal (nickelcopper- platinum-palladium) formation at a depth of 37 metres. The intersection over the entire width (from 38 metres to 108 metres) graded 0.23% nickel; 0.11% copper and 1.05g/t 3E (platinum, palladium and gold). The platinum to palladium ratio is 1 to 1.

BLUE RIDGE AND SHEBA’S RIDGE STUDY FEASIBILITY

Ridge Mining changed its name from Cluff Mining in May 2005, following its decision to focus on its platinum assets. Prior to this Algy Cluff, who headed Cluff Mining, had invited Terence Wilkinson, the former chief operating officer of Lonmin, to join the Cluff Mining board. Wilkinson, who is now CEO of Ridge Mining, introduced Martin Sharpe, co-founder of Sperrylite which owned platinum rights in South Africa, into the partnership. Of the four projects that came out of that agreement, the number has been reduced to two, these being Blue Ridge and Sheba’s Ridge, while a third, Fountain’s Ridge, has since been added.

BLUE RIDGE – FEASIBILITY ALMOST DONE
The more advanced of these projects is Blue Ridge, which is an underground mineable platinum project whose feasibility study is under revision. A great deal of drilling (some 92 boreholes drilled with 155 deflections) had been done in 2003, but the change in the rand environment required an optimisation of the original feasibility work. This has been done over the past 18 months. Blue Ridge has the potential to be a UG2 reef platinum mine from surface to 800 metres underground, at a rand price of R6.50 to the dollar.

ANGOLA’S CAMAFUCA PROJECT GOES FORWARD

The Angolan government recently approved the formation of the operating company Sociedade Mineira do Camafuca Lda (SMC). This company will hold the mining licence for the Camafuca diamond project allowing construction of the project to commence. The project involves a joint venture between SouthernEra Diamonds and Angolan state owned diamond group Endiama.

Camafuca is one of the largest known undeveloped diamondbearing kimberlite complexes worldwide and is located in the Lunda Norte province in north-eastern Angola 20 kilometres southeast of the town of Lucapa. The project area covers the outcropping primary kimberlite deposits associated with the five Camafuca-Camazambo kimberlite pipes with a combined surface area of 160 hectares.

ANGOLA GEARS UP POWER FOR CATOCA EXPANSION

What is expected to be the largest and most sophisticated power station, at a mine in Angola has been commissioned after an extensive overhaul undertaken by Barloworld Equipamentos – Angola. Planned expansion of production at the Catoca diamond mine, in Angola, has necessitated the increase of the power station’s capacity from 12 MW to 24 MW and Barloworld Equipamentos - Angola, which developed the original power station at the mine, commissioned the upgraded facility in August 2005.

HARMONY’S GROWTH PROJECTS ON TRACK

Two of Harmony Gold Mining Company’s growth projects, Doornkop and Phakisa, recently reached milestones in their development. The Doornkop South Reef project is a R1 billion (US$0.15 billion) project involving the deepening of the existing Doornkop Mine to access the South Reef. The project is due to commence production in October 2006 and will achieve peak production of over 300,000 ounces in 2009.

THE EVOLUTION OF PNEUMATIC CONVEYANCE

As a specialist in pneumatic conveying together with their partner Claudius Peters, ELB Engineering Services recently launched its Fluidcon system. Pneumatic conveying has always been an acceptable means for transporting fine materials from one location to the other. From a positive point of view, the initial investment and maintenance costs are typically lower when compared to mechanical conveying systems. However, the energy consumption for the air supply on pneumatic systems is considerably higher than other options power requirements.
The Claudius Peters Fluidcon system uses the advantages of typical pneumatic conveying at considerably lower energy requirements.

SCREEN AT XSTRATA CHROME

A 10 ft OmniScreen, the largest of its kind in the world, has been supplied to Xstrata Chrome Kroondal by minerals processing specialist IMS Engineering. It was installed during December 2005 and will be instrumental in chrome ore processing at the operation near Rustenburg, in the North West.

Xstrata plant engineer Johan Hattingh says that the 10 ft OmniScreen is the ideal screen for the chrome ore beneficiation facility, which is currently being upgraded to process up to 300 tonnes of chrome ore an hour.
