The company said that the earnings were affected by non-cash impacts of Leach Tank failure at Ranger uranium mine, including a drawdown in finished goods inventory and decline in depreciation.

The mine was forced to suspend operations after a uranium spill in December 2013. In June this year, the Australian government and Northern Territory allowed for resumption of Ranger processing plant.

Located near Kakadu National Park, the processing plant is on track to reach full processing capacity in the September quarter. It is expected to produce 1,100 to 1,500 tons of uranium oxide this year.

Revenues during the six-month period increased 26% to A$171.6m ($159.9m) from A$136.2m ($126.9m) a year ago.

Sales volume was increased 33% to 1,524 ton, compared to 1,147 ton sold in the previous year period. For the second half of 2014, sales volumes are expected to be broadly in line with the first half of the year, the company said.
