Buchans Barite Harvesting and Processing Operations

Proponent: Barite Mud Services Inc.

Summary of Environmental Assessment Process

Project Description:

Buchans Barite Mud Services Inc. is proposing to re-start the Buchans Development Corporation owned barite operation in order to recycle remaining base-metal tailings from ASARCO’s Buchans mine and to extract and concentrate barite for sale and use as drilling mud to be used in Newfoundland and Labrador’s offshore oil industry. This is a brownfield operation and will process tailings currently stored in a tailings pond (TP1). Tailings will be removed from TP1 via dredging. No new construction is required. Approximately 40,000 - 50,000 tonnes will be removed per season to make 10,000 tonnes of barite product. Extraction operations will commence in early May and continue until late October annually. The operation is anticipated to start during the summer of 2014 and continue for a minimum of 15 years.
