Alliance Craton Explorer (ACE), a division of Alliance Resources and a minority partner with 25% stake in the project, had voted against the decision.

Quasar has plans to implement its start-up plan comprising an in-situ recovery operation at Four Mile East in Q2 2013 and at Four Mile West in Q4. First uranium sales from the mine are expected in Q3 that year.

Heathgate Resources, an affiliate of Quasar, will undertake uranium capture at the Pannikan satelite plant and elution, precipitation, drying and packing at the Beverley processing plant, as part of the start-up plan.

The company expects to produce 2.1 million pounds of uranium oxide over 16 months, incurring expenditure of A$97.8m until December 2013.

According to Quasar, the start-up plan enables the company to consider production rates with a staged start of mining operations before the construction of full-scale production facilities.

A statement from ACE said that the company considered the construction of a stand-alone plant at Four Mile would produce a better outcome.
