were commissioned in September 2010 Iron ore mining began in November 2010; ramping up to a throughput of per year. The mine had been the subject of a legal dispute during and after the final stages of production. Moly Mines had conducted a mine gate sales agreement with Mineral Resources Limited, under which the latter paid A$35 million in advance for an expected 2.4 million tonnes of iron ore from the mine. Concluded in 2013, the deal was to extend to the completion of mining at Spinifex Ridge, with a final payment in the range of A$3 million due upon this. As part of this agreement, Moly Mines accepted that it could potentially owe money to Mineral Resources, depending on the amount and quality of ore mined. In November 2015, an expert adviser concluded that Moly Mining owned Mineral Resources A$4.2 million, a sum the former disputed. Subsequently, Mineral Resources launched legal action in the
