Hycroft mine is located 87 km (56 miles) west of Winnemucca in Humboldt and Pershing Counties, Nevada, USA.

A small scale gold oxide heap leach mining operation started in 1983.Hycroft is a conventional open pit mining operation that treats the oxide ore through heap leach methods and recovers the gold by using a Merrill Crowe method.
