Stage 2
Commissioning of the US$50 million Stage 2 production expansion to 3.7Mlb U3O8 per year has been completed and nameplate production was realised prior to year end 2009 in the December month.
Stage 3
Construction on the Stage 3 expansion to take LHM from 3.7Mlb pa to 5.2Mlb pa is progressing well and is currently causing very limited interruptions on the normal plant operations. During the next 3 quarters, however, some plant operating downtime is expected to facilitate the tie-in of major components. In some instances the tie-ins will start contributing to increased performance of the existing plant.
Stage 4
The drilling programme to upgrade the bulk of the previously defined uranium resources to the Indicated and Measured JORC categories was completed in May. A total of 1,203 holes for 38,592m were drilled. An upgraded resource estimate is expected in the next quarter. It will be used for a new reserve estimation to underpin the Stage 4 feasibility study to expand LHM to 9Mlb U3O8 pa.
