The Hycroft heap leach operation re-opened in 2008. Initially the plan was to expand the mine within six years and process the refractory sulphide ore beneath the oxide cap. High operating costs combined with low gold and silver prices resulted in Allied Nevada filing for bankruptcy protection in March 2015. Following an agreement with its creditors the company emerged from bankruptcy protection in October 2015, having raised US$227 million. The company also changed its name to Hycroft Mining Corp. Wood Mackenzie assumes that the sulphide operation will commence in 2021 at the earliest.
