Evaluation of Chemical Product for Tailings Facility Evaporation Reduction at the New Afton Mine

New Gold Inc.

The environmental safety of a chemical product used to aid in Tailings Storage Facility evaporation reduction was evaluated by Borealis using generated environmental data, and an ecological risk assessment approach. This included: the development of a problem formulation for the evaluation; a review of historical ecotoxicological information pertaining to the product; a summary of methodologies used in the testing/evaluation of the product (independently commissioned by Borealis); reporting of results, conclusions and interpretation; and a full third-party evaluation.

The project included liaison and consultation with provincial regulators (BC MOE) and a local First Nation (Stk’emlupsemc te Secwepemc Nation).
