After having electrical power restored to the mine site three weeks later than anticipated due to scheduling delays with the electrical power authority CFE, personnel commenced dewatering the mine.
"Access has been restored to the El Largo zone, where there is approximately 50,000 tonnes of broken mineralised material available for transport to the mill site and at the mill site, approximately another 20,000t of previously mined transported mineralised material is available to begin processing upon start-up," the company said.
"Personnel are advancing on the process of checking, servicing and repairing, as necessary, all mill processing equipment, mobile mining equipment, underground mining equipment, ventilation systems and safety equipment."
While a specific restart date was not available, the miner estimated it would resume operations by the middle of the month.
Canada-based Telson Mining owns 100% of Campo Morado, and operated it for 22 months after bringing the mine back to life in October 2017 and sending it into care and maintenance in August 2019 as a result of declining zinc prices and community issues. It cited "improving current conditions" for the move.
Sister project Tahuehueto in northwestern Durango state, Mexico, is currently under development and waiting for final funding to wrap up work. Its construction has advanced to approximately 70% completion.
