Kirkland Gold has awarded a contract to Veolia Water Technologies for the design and supply of a Reverse Osmosis plant to reduce chloride levels in the produced water stream at the Fosterville Gold Mine.
The Kirkland Lake Gold owned and operated Fosterville Mine is a high-grade, low-cost underground gold mine located 20 kilometres from the local city of Bendigo.
With an extensive exploration potential, the Fosterville Mine operations have recently experienced a significant increase in gold production. The water treatment plant solution will allow Kirkland Lake Gold to continue meeting their operations license conditions in a sustainable way.
The water treatment plant will process mine water for reuse within the process water circuit, reducing the chloride levels to < 500 mg/L.
The Reverse Osmosis plant will consist of multimedia and carbon filtration followed by primary Reverse Osmosis and reject recovery Reverse Osmosis.
“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”, said Leno Cavarra, Client Executive Manager Projects, Veolia Water Technologies (Australia).
The water treatment plant has the capacity to treat 2 megalitres per day (ML/d) and is planned to be operational in 2019.
Kirkland Lake Gold is a mid-tier gold producer with target production in 2018 of over 620,000 ounces from mines in Canada and Australia. The production profile of the Company is anchored by two high-grade, low-cost operations, the Macassa Mine located in Northeastern Ontario, and the Fosterville Mine located in the state of Victoria, Australia.
