Excerpt from Great Basin Gold article:
Due to the commissioning of the Esmeralda mill and the high toll milling costs
associated with treatment at Newmont's Midas mill, the Company elected not to
treat any ore in the third quarter of 2009 and, as a result, did not record
any revenue during the period. The Company has subsequently also entered into
an ore processing agreement with Yukon-Nevada, to process the 30,000
additional ore tons currently stockpiled at the Hollister property, at a cost
of US$88 per ton. Fixed recoveries of 88% for both gold and silver have been
agreed to.
