BRITISH COLUMBIA – Chieftain Metals of Toronto has received the discharge permit for the new water treatment plant it build at the Tulsequah Chief mine project 100 km south of Atlin. The site had a legacy of acid mine drainage from operations that ceased in the 1950s. With the commissioning of the new plant in December 2011, the site has been considerably remediated.
Treatment of acidic water thus far has shown significant improvement in discharge water quality, with initial test results showing a reduction of greater than 98% of the metals load compared with untreated mine water. Additionally, the water discharged from the plant is within regulatory water quality guidelines and Chieftain says it is consistently achieving high quality plant discharge water with contaminant levels below the published limits of the federal government's Metal Mining Effluent Regulations.
Although a short-term solution, this water treatment process will ensure that the water entering the Tulsequah River is clean and does not negatively impact the rivers' fish and aquatic life.
Chieftain is preparing the Tulsequah Chief polymetallic deposit for mining. Learn more at ChieftainMetals.com.
