:: BioteQ Announces New Tailings Recovery Project Operational at Caribou

BioteQ Environmental Technologies Inc. has announced the successful commissioning of the new tailings recovery plant at the Caribou site. To date approximately 15,000 tonnes of tailings have been treated.

The first stage of the expansion plan at Caribou was successfully commissioned in May with the startup of the High Density Sludge (HDS) lime circuit, as previously reported. The HDS plant was built to improve lime utilization efficiency and reduce the volume of sludge produced in the lime circuit. The second stage of the expansion plan at Caribou, a 50,000 tonne per year tailings treatment circuit, has now been commissioned. The tailings, deposited at the Caribou site by previous operators prior to ownership by CanZinco Ltd (a subsidiary of Breakwater Resources Ltd), contain mobile heavy metals, such as copper and zinc, and contribute to water contamination at the site.

Initiated in June, the plant commissioning has been completed and the plant is now operating at the design capacity of 12,000 tonnes per month, on a campaign basis during the summer and fall seasons. The plant has treated approximately 15,000 tonnes since startup with the objective to treat 50,000 tonnes in total this year.

The tailings recovery plant Caribou is a new operation for BioteQ and provides the company with additional operating expertise that could be utilized at other sites, in combination with the BioSulphideŽ Process for metal recovery, to offer complete tailings and water management services combined with metal recovery.
