PRESS RELEASE: The water treatment plant solution will allow Kirkland Lake Gold to continue meeting its operations license conditions in a sustainable way.

Kirkland Lake Gold is a mid-tier gold producer targeting 580,000-595,000oz of gold production in 2017 from mines in Canada and Australia. In Australia, Kirkland Lake Gold owns and operates the Fosterville mine, which is a high-grade, low-cost underground gold mine, located 20km from the local city of Bendigo. The Fosterville mine features extensive exploration potential and low-cost production. The mine is currently experiencing a significant increase in gold production due to recent exploration.

The Fosterville gold mine plans to implement a water treatment plant to treat mine water for reuse within its process water circuit.

Veolia Water Technologies has been awarded the contract for the design and supply of a reverse osmosis plant to reduce the chloride levels < 500mg/L. The reverse osmosis plant will consist of multimedia and carbon filtration followed by primary reverse osmosis and reject recovery reverse osmosis.

Leno Cavarra, client executive manager - projects at Veolia Water Technologies (Australia), said: "Leveraging our extensive experience in reverse osmosis technology for treating mine water, we are very proud to deliver this water treatment system to enable Kirkland Lake Gold to further enhance its sustainability credentials by producing a high quality treated water for reuse within the mine."

The water treatment plant has the capacity to treat 2 million litres per day and is planned to be operational in 2019. This water treatment plant solution will allow the Fosterville gold mine to continue meeting its operating license conditions in a sustainable way.
