Victor Wyprysky, President and CEO of Chieftain Metals Inc., commented: “Chieftain’s immediate attention to provide a solution to the historic environmental issues at Tulsequah demonstrates the high importance we place on community and stakeholders concerns as we move “The Chief” to construction start.”

Treatment of mine-impacted 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 un-treated mine waters. Additionally, the water discharged from the plant is within regulatory water quality guidelines and the Company 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.
