The job cuts are a direct result of increasing costs against a weak outlook for uranium prices in the recent past.

Since the Japanese tsunami in 2011 demand for uranium declined, while prices reduced by more than 36%.

Rössing incurred its second consecutive major operational loss of $53m in the 2012 financial year and has failed to generate any profits from operations despite stringent cost reductions by 31%.

Losses were recorded even after production rose 26% to 2699t along with continued operational efficiencies through improved productivity, reduced contractor spend and improved ore grade.

"With the utility sector in Japan essentially shutdown, there is little prospect of a turnaround in the near term," the company said in a statement.

Rössing stated that the company has resisted the need to cut jobs at the mine for as long as possible, but has no alternative now.
