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 early Lalor ore. In 2014, Hudbay refurbished equipment and facilities at the concentrator, which now has the capacity to treat 2,700 tonnes per day. The concentrator currently processes ore from Lalor and produces zinc and copper concentrates. The zinc concentrate is shipped by truck for further processing at Hudbay’s zinc plant in Flin Flon. Tailings generated by the Snow Lake concentrator are deposited in Hudbay’s Anderson Lake tailings facility, which the company believes mitigates environmental impacts, as the tailings are deposited in a subaqueous manner, minimizing the potential for generation of acid rock drainage.

On May 4, 2015, Hudbay closed a transaction to acquire a 100% interest in the New Britannia mine and mill, located in Snow Lake, Manitoba, for approximately US$11 million in net cash consideration, plus a contingent payment of US$5 million. The New Britannia mill (the “NBM mill”) is currently on care and maintenance. If refurbished, it has the potential to process approximately 2,000 tonnes per day of gold zone ore from the Lalor mine, and includes an existing Carbon-in-Pulp circuit that has historically produced gold doré on site. It is expected that a paste backfill plant for Lalor will be required in addition to the refurbishment of the NBM mill. Ore from Lalor will continue to be processed at the Snow Lake concentrator, while engineering work is carried out on a potential restart of the NBM mill. It is anticipated that the results of a technical study on the NBM mill, including the estimated costs and timing of a potential restart, will be available in 2016.
