COMPANY ANNOUNCEMENT / MEDIA RELEASE
Rössing South Project Feasibility Study Update
Australia – March 12, 2010 – Australian-based uranium mine development and exploration company, Extract Resources Limited (ASX/TSX: EXT) (“Extract or “the Company”) reports that the Rössing South Definitive Feasibility Study (“DFS”) continues to progress well and is on track to confirm the project’s potential to be one of the world’s largest uranium mines. The base case mine plan remains low risk, bulk tonnage, open pit mining, with ore processed through a conventional agitated tank leach plant.
The size of the Rössing South mineralized system continues to grow with strong drilling results continuing from Zones 1 and 2. There are encouraging indications of significant mineralization on the western limb of the Rössing South antiform and high grade mineralisation in both zones.
Extract aims to announce an updated Rössing South resource in Q3, 2010. This revised resource estimate will incorporate infill and extensional drilling that has been completed since July 2009. The updated estimate is expected to increase the overall size and confidence levels of the Rössing South resource.
As part of the ongoing process of optimising the currently defined resource, the most recent mine plan incorporates an average stripping ratio of 6.9:1 over the life of mine. Open pit mining studies indicate that approximately 120 Mt of pre-strip material is to be removed to enable ore movement rates of approximately 15 Mtpa to feed the processing plant.
As outlined in the Preliminary Cost Estimates (“PCE”) released on 3 August 2009, several items were excluded from the initial capital cost estimate. Extract is continuing to refine the cost of independently developing Rössing South, including the costs of using either an owner-operator mine fleet or contract mining. Studies to fully define the costs associated with procurement of water, power and acid delivery, together with external infrastructure including rail and road, are ongoing.
Extract, together with its technical consultants, continues to undertake value engineering to optimize the development of the project and will provide an update following completion of the DFS, completion of which is currently targeted for Q4 2010. An example of this is pilot plant metallurgical testwork which is currently commencing operation in Perth. Extract expects this work to confirm overall process plant recovery as well as reagent and acid consumption.
Extract notes that capital costs for the processing plant and annual operating costs are currently expected to remain in line with the PCE.
