DE BEERS STAYS AHEAD IN EXPLORATION GAME

Canada has been a focus point for the group’s exploration in recent years, with it having accounted for up to 40% of the total exploration budget. In 2006 this will fall to about 10%. Outside Africa De Beers’ greatest focus areas for exploration in 2006 will be India, accounting for some 8%, and Russia, accounting for 2% of the group’s exploration budget. De Beers group exploration manager, Bill McKechnie, says that with De Beers only just entering Russia in terms of exploration that is still seen as in a start up stage.

“About 65% of our 2006 exploration budget will be spent in southern and central Africa,” McKechnie says.

SIERRA LEONE’S KOIDU MINE CONTINUES ITS RAMP UP

Energem, which owns 40% of the Koidu diamond mine in Sierra Leone, is predominantly an oil and gas group, with only an approximate 15% of the company’s value attributed to its diamond mining and exploration. The company, which was formerly Diamondworks, has expanded to become a mid-tier group, and in so doing its mining arm has been diluted.

However, Brian Menell, chairman of the group which now employs about 1,100 people, says this does not mean that Energem isn’t looking to expand its solid minerals business. “We are using our political understanding, credibility and infrastructure in some 17 African countries to look for mineral opportunities, and we are looking at minerals beyond diamonds as well,” he says.

PAVILION AND HATCH IN WORLDWIDE AGREEMENT

Pavilion Technologies, which specialises in advanced process control (APC) and environmental compliance solutions, has formed a worldwide strategic alliance with Hatch.

The partnership will provide Hatch customers in the cement, mining, metallurgy, and energy (hydro, windpower, and fossil) sectors with industry-specific solutions powered by Pavilion8 advanced process control and performance management software. The initial geographic focus of the partnership will be in North America, South Africa and Australia.

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.

APE PUMPS SETS ITSELF APART

APE Pumps is a manufacturer of specialist pumps, and an estimated 25% of its business is either directly or indirectly linked to the mining sector.

It has both the experience of a long history, and the energy of a new and dynamic company. APE Pumps’ history goes back to its formation in the United Kingdom in 1878, and it opened its first South African office in 1892. In 1952 the company began manufacturing in South Africa, under the name Sangus. However, APE Pumps is also only in effect nine years old as it took its present form in 1997, following a management buyout. Today the Gauteng, South Africabased company employs 65 people, in addition to the 54 people at its forge, where it manufactures the castings for its pumps. APE Pumps’ casting facility uses some 60% to 65% of its capacity on APE products and also does work for other companies that are not direct competitors. The castings factory does some 60 tonnes a month of castings.

BLUEPRINT FOR BIODIVERSITY GOOD PRACTICE IN MINING

Mining companies seeking to improve their biodiversity performance can now do so with the help of a new 142- page guide that has been published by the International Council on Mining and Metals (ICMM).

ICMM’s Good Practice Guidance for Mining and Biodiversity is designed for use by mining companies at all stages of their operations, from initial exploration to mine closure planning and implementation.

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.
