OCTOBeR 2011 NeWS FOR THe FRIeNDS aND peOpLe OF SWaKOp URaNIUM This was the good news from the latest reserve estimate. Not only is there more uranium: the ore grade in Husab Zones 1 and 2 shows a 4% increase in forecast grade from 497 parts per million (ppm) to 518 ppm uranium oxide. It furthermore shows a 15% reduction in life-of-mine strip ratio. Total ore tonnes within the reserve have increased by 37% to 280 million tonnes. In short, we will be getting a better grade than originally thought, have to remove less waste rock to get to it, and have much more ore to process. The strip ratio now stands at 6,2:1 (previously 7,3:1), which means that just over six tonnes of waste rock have to be removed to obtain one tonne of ore. The reduction in strip ratio is expected to have a positive effect on project economics. The 20-year mine life, which includes pre-strip and ramp-up, is based on the definitive feasibility study (DFS) processing target of 15 million tonnes of ore and 15 million pounds (6 800t) of U3O8 per year. Once this production is reached, Husab will become the world’s third-largest uranium-only mine. young child grappling with his times tables in primary THaT school right now, could well be an engineer working there’s MoRe to Husab for Swakop Uranium’s proposed Husab Mine in 20 years’ time. The According to Jonathan Leslie, CEO of Extract Resources (Swakop proposed mine near Swakopmund now has a potential mine life of Uranium’s 100% shareholder), the updated reserve estimate marks the more than 20 years and uranium reserves of at least 280 million tonnes.
