Operations halted at El Teniente mine

The El Teniente mine, located in the O'Higgins region, suffered a collapse on 31 July. The collapse in the Andesita sector of the mine is understood to have been as a result of seismic activity that registered 4.2 on the Richter scale. It remains unknown whether the seismic activity was caused by the mining operations or natural activity, according to industry sources. Underground operations are to be halted for an unknown period of time while the open air sector, which represents around 10% of the total production, will remain open, according to industry participants.

Copper output begins at Rio Tinto-backed project

Gunnison has started producing pure copper cathodes at its Johnson Camp Mine (JCM) in southeast Arizona, United States, from a solvent extraction-electrowinning (SX-EW) circuit and using leaching technology from Rio Tinto-owned Nuton. As well as giving Gunnison exclusive rights to deploy the proprietary process on run-of-mine ore, Nuton is a financial partner of the Phoenix-headquartered mine developer which has restarted copper production at past-producing JCM. The company’s next goal is to ramp-up to nameplate plant capacity of 25 million lbs/year (11,300 t/a) of finished copper.
