Johnson Camp Mine
On December 15, Excelsior acquired the Johnson Camp Mine (JCM) for total consideration of US$8.4 million. JCM mining claims are contiguous with Excelsior’s Gunnison Project. The property consists of 59 patented lode mining claims, 117 unpatented lode mining claims and fee simple lands. The existing facilities includes a 4500 gallon per minute solvent extraction plant, a tank farm, an electrowinning plant with 88 electrowinning cells with capacity of 25 million pounds of copper cathode per annum, solution storage ponds, a truck shop, core storage building, offices, warehouse, laboratory, mechanical shop, a primary and secondary crusher, and various other equipment.
Johnson Camp Mine has a long history, with copper production dating back to the 1880s. Mining operations at JCM stopped in 2010 and has since been producing small amounts of copper from residual leach pads. The mine had been in receivership since 2014.
SX-EW Processing Facility
The SX-EW (Solvent-Extraction-Electrowinning) plant is in good working order and has an annual capacity of 25 million pounds of copper cathode. The SX-EW plant also includes solids containment ponds and related infrastructure necessary for production.
Johnson Camp Mine is located just one mile north of Excelsior’s Gunnison deposit; this close proximity will allow for Gunnison copper solution to be piped to the SX-EW facility at JCM for processing into pure copper cathode.
