Excelsior believes Nuton’s proprietary applied sciences supply the potential to supply extra copper in an economical method and have important environmental advantages by lowering waste from new and ongoing operations.
The primary stage of the collaboration entails Nuton finishing sure take a look at work on supplies collected from the corporate’s Johnson Camp mine challenge to verify that appropriate circumstances exist to deploy the heap leaching applied sciences.
Assuming this take a look at work is profitable, the events would then work towards negotiating industrial phrases for a full-scale deployment of the Nuton applied sciences on the Johnson Camp mine.
The take a look at work is predicted to start in the course of the first quarter of 2023, with a view towards doubtlessly negotiating industrial phrases depending on the take a look at outcomes and different components in the course of the third quarter of 2023, Excelsior says.
The Johnson Camp mine has traditionally been a heap leach operation for the reason that Nineteen Seventies. It consists of two open pits, a two-stage crushing-agglomerating circuit, a completely functioning solvent extraction-electrowinning (SX-EW) plant able to producing 25 million lb. of copper cathode per 12 months.
Excelsior is presently exploring re-opening the Burro and Copper Chief pits – beforehand mined in 2010 by Nord Assets – to supply run-of-mine materials that may be positioned on a brand new leach pad as a method of extracting copper from the remaining mineral assets throughout the two pits.
The corporate additionally owns and operates the Gunnison copper challenge in Arizona, a low-cost, environmentally pleasant in-situ restoration copper extraction challenge that’s permitted to supply 125 million lb. of copper cathode per 12 months.
