The mill project at Hycroft is separate from and in addition to an expansion of heap leach operations is currently in progress. The heap leach expansion includes increasing the mining rate by implementing a largerscale mining fleet, additional leach pad capacity, and crushing of 30% of the ore using semimobile crushing plants.

The Pan amalgamation process is a method to extract silver from ore, using salt and copper(II) sulfate in addition to process was widely used from 1609 through the 19th century; it is no longer used. The patio process had been used to extract silver from ore since its invention in 1557. One drawback of the patio process was the long treatment time, usually weeks.
The Minto mill. Originally designed for a throughput of 1,563 t/d, the Phase 2 mill expansion brought the tonnage up to 2,400 t/d. Blended and crushed ore travels over a live feeder to a Marcy by semiautogenous (SAG) mill. The slurry is cycloned and passed though a pair of secondary Marcy by ball mills.
