FLIN FLON — The flagship Flin Flon mine, which has now reached the end of its life, is complete – and parts of other operations are not far from the same.

Hudbay continued its efforts to close the 777 mine site, filling in the mine portal and removing key infrastructure. The company says closure efforts at the 777 mine are nearing completion, with several final closure-related tasks either complete or nearing completion.

The closure of other facilities in the Flin Flon area is also underway, and efforts to close the Flin Flon processing plant and zinc plant continue. The closure of these facilities is expected to complete in the coming weeks, likely in early September, while parts of the Flin Flon plant will be temporarily used to support the company’s tailings processing facility before the closure. from the factory itself.

“The closure of the zinc plant is ahead of schedule, with the majority of activities completed and minor clean-up activities to be carried out in early September,” read a statement from the Hudbay spokesperson.

Hudbay completed its final blasting at the 777 mine in June, then shut down operations at the mine a few days later, followed by the processing of that final ore later in the month. The company has also moved workers from its Flin Flon operations to operations near Snow Lake, such as the Lalor mine and the New Britannia mill. Equipment has also been moved up the highway to Snow Lake from the 777 and Flin Flon or will be auctioned off next month.

Not all Hudbay operations in Flin Flon are closing. The company will service and maintain its tailings facility, both to provide a contingency plan should the Flin Flon facilities restart and to fulfill its own environmental obligations to the site. A very small number of workers – about 50, according to old company estimates – will be stationed at the Flin Flon tailings facility, while some administrative and machine shop jobs will be based outside the Flin Flon facilities.
