Excelsior intends to restart operations of the historic Johnson Camp copper oxide open pits, that were previously mined in 2010 by Nord Resources.
The only additional infrastructure required are, a new leach pad and minor piping and pumping facilities.
Operations could provide up to 65.9 million pounds of copper over 3 plus years
Work is ongoing to advance restarting mining from the existing Johnson Camp Mine pits

*The PEA is preliminary in nature and includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that the conclusions reached in the PEA will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability
