Uranium oxide production for the June 2009 quarter of 1,481 tonnes was 44 per cent higher than the June 2008 quarter, as a result of improved grades and mill throughput, and 22 per cent higher than the March 2009 quarter due to improved throughput.  


Ore milled for the quarter was 21 per cent higher than the previous quarter and 7 per cent higher than the June 2008 quarter, due to improved utilisation and milling rates.  The laterite processing plant also contributed to production in the June 2009 quarter.


Ore grade processed was 0.28 per cent uranium oxide (March 2009 quarter: 0.29 per cent)29 per cent higher than the June 2008 quarter (0.22 per cent) when the mill processed stockpiled lower grade ore for the majority of the quarter.  In the June 2008 quarter, lower average grade resulted from restrictions in access to higher grade ore located at the bottom of the pit, and the depletion of stockpiled higher grade ore as a result of the effects of the significant weather event in February 2007. 


Ore mined was 48 per cent higher and material mined 23 per cent higher than the March 2009 quarter, due to improved access to the pit following the end of the 2009 wet season and the sequencing of waste and ore removal.  Compared to the corresponding period in 2008, ore mined was 10 per cent  lower primarily due to mine sequencing and material mined was 16 per cent lower primarily due to longer haul distances. 


EXPLORATION AND EVALUATION    

Work continued on the Ranger Expansion Project, involving the development of a heap leach facility at the Ranger operations for the extraction of 15,000 to 20,000 tonnes of uranium oxide contained in low grade mineralised material currently on the stockpiles and yet to be mined 

On 19 May 2009, ERA announced that the proposed heap leach facility would be subject to environmental assessment under the Northern Territory Environmental Assessment Act and the Commonwealth of Australia Environmental Protection & Biodiversity Conservation Act (EPBC Act), at the level of an Environmental Impact Statement.  The Northern Territory and Commonwealth governments have not yet released the draft guidelines for the Environmental Impact Statement for public comment. 

Studies are continuing regarding the Ranger 3 Deeps ore bodywith a current resource of around 34,000 tonnes of uranium oxide. On 19th May 2009, ERA announced that the Commonwealth government had determined that the proposed exploration decline project, to conduct close spaced underground exploration drilling to further evaluate the extent and continuity of the Ranger 3 Deeps ore body, would not be subject to environmental assessment under the Commonwealth EPBC Act. ERA has not yet been notified by the Northern Territory government whether this project will be subject to further environmental assessment under the Northern Territory Environmental Assessment Act.

Total evaluation expenditure during the June 2009 quarter was $4.9 million, compared with $5.4 million in the March 2009 quarter, for a total of $10.3 million in the June 2009 half year, which has been expensed.

During the June 2009 quarter, 12 exploration drill holes were completed for 3784 metres. Exploration  expenditure for the June 2009 quarter was $1.5 million (June 2008 quarter: $4.2 million), compared  with $2.2 million in the March 2009 quarter, for a total of $3.7 million in the June 2009 half year  (June  2008 half year$8.0 million), which has been expensed.

The table below shows the most significant results for exploration drilling during the quarter.

All intersections were determined using a 0.08% U3Ocut-off at a minimum five metres composite, including a maximum of two metres of non mineralised internal material. Intersections are down-hole lengths and the true width of the intersections has not been calculated.
