Excelsior intends to restart operations of the Johnson Camp open pits, incorporating sulfide leaching technology to improve recoveries.
The only additional infrastructure required are, a new leach pad, crusher and agglomeration refurbishment, leach pad stackers and minor piping and pumping facilities.
Plans include mining oxide, sulfide, and transition material from the Burro and Copper Chief pits for approximately 20 years and heap leaching for an additional year to produce copper cathode at a capacity up to 25 million pounds per annum.
Total copper to be produced is 492 million pounds.
Work is ongoing to advance restarting mining from the existing Johnson Camp Mine pits
