Snow Lake Concentrator

Hudbay’s concentrator in Snow Lake, Manitoba was re-started in late 2009 and a new copper recovery circuit was installed in the third quarter of 2012 to facilitate processing of Lalor ore. In 2014, Hudbay refurbished equipment and facilities at the concentrator, and the concentrator now processes approximately 3,000 tonnes per day of ore production from the Lalor mine and produces zinc and copper concentrates. The majority of the zinc concentrate is shipped by truck for further processing at Hudbay’s zinc plant in Flin Flon, with the excess zinc concentrate sold to market. Tailings generated by the Snow Lake concentrator are deposited subaqueously in Hudbay’s Anderson Lake tailings facility. A paste plant is currently under construction at the Lalor mine, and once completed the majority of the tailings produced from the Stall mill will be pumped to the paste plant, dewatered, mixed with cement and sent underground as pastefill.

In 2015, Hudbay acquired a 100% interest in the New Britannia mine and mill, located in Snow Lake, Manitoba. The New Britannia mill  is currently on care and maintenance. If refurbished, it has the potential to process up to 1,500 tonnes per day of gold zone and copper-gold zone ore from the Lalor mine and may provide a more attractive alternative to transporting Lalor ore to Flin Flon for processing. The New Britannia mill includes an existing Carbon-in-Pulp circuit that has historically produced gold doré on site.
