Following is the third of three hand outs from the annual meeting; it is not dated and it appears to be a photocopy from a publication called "National". Headline: Microwave technology used to unlock mineral wealth Sub Headline: Local group Bateman teams up with Canadian firm to market product locally By: Llja Graulich Engineering group Bateman Project Holdings (Bateman) has teamed up with Canadian company EMR Microwave Technologies to jointly market and distribute a product which could revolutionise the mining world. The process uses microwaves to unlock gold, copper and other metals from refractory and hard ores and has proved in tests to be substantially higher yielding than other methods. It offers also more effective metal recovery at operations struggling to come to terms with extremely sulphide ore bodies. The microwave process comes in at the extraction stage, when ore has been brought to the surface for treatment. EMR has been running tests over a number of years and has used more than 300 different ore suites, 80% of which have been gold related, to test its product. Bateman CEO John Herselman says his company's involvement will be to bring the product to a commercial production level and assist EMR in providing total solutions to clients. Bateman has taken an equity stake in EMR which has also ensured the group receives the exclusive rights for the product on all mineral related usages. While patents have been taken on the technology, Herselman says that even if other companies were to develop similar products the venture between Bateman and EMR is three to five years ahead of the pack. Bateman has known about this technology for more than a year but had to satisfy itself that this process has "something revolutionary". Herselman said his first reaction was that "this idea had to be too good to be true". The company hopes to have a pilot plant up and running in SA within the next year and this will add to the interest of various mining companies. EMR president James Tranquilla, who has more than 30 years experience in microwave technology, said that while his company had tested the technology mainly on gold related ore, its use could be spread across the whole metal range. Herselman said he sees the main application of the microwave technology not in gold but in base metals and specifically copper. The vast copper belt in Zambia and the Congo could be ideally suited. The product can also make commercially viable those mineral reserves previously rejected as uneconomic because of extraction difficulties. However, Herselman said, the mining industry was known for its conservatism and he would just let things run at their natural pace. Tranquilla said a positive for companies in times of low metal prices was that the technology was cheaper at the set up stage, but cost savings would really come to the fore at the production level.
