SNC-Lavalin Awarded EPC Contract by Codelco Division Norte for the Construction of Two Sulphuric Acid Plants

MONTREAL, Nov. 22, 2016 -SNC-Lavalin (TSX: SNC) is pleased to announce that it has been awarded an engineering, procurement and construction (EPC) contract by Corporación Nacional del Cobre de Chile (Codelco), one of the largest copper producers in the world, for the construction of two sulphuric acid plants at the Chuquicamata Copper Smelter Complex, located in the Antofagasta region of northern Chile.

This project incorporates the best-in-class sulphuric acid production technology by MECS Inc., a wholly owned subsidiary of DuPont, with whom SNC-Lavalin has successfully executed projects for over 50 years. The plants will treat off-gas from the Chuquicamata smelter, each producing up to 2048 metric tonnes of market grade sulphuric acid per day. These new plants will replace those currently in operation at the facility and are part of Codelco's ongoing environmental compliance plans.

Construction is expected to begin in early 2017 with SNC-Lavalin performing basic and detailed engineering, procurement of equipment, and construction of the acid plants via their Santiago and Toronto offices.

"Following our recent contract award for the replacement of the Effluent Treatment Plant at the Chuquicamata Copper Smelter, this new contract once again supports our strong position in Latin America", said José J. Suárez, President, Mining & Metallurgy. "We are very proud to be part of a local project that, once completed, will not only provide Codelco with first class acid plant facilities, but will be a key element in their environmental program for the future. Codelco's environmental values are closely aligned with those of SNC-Lavalin and this adds to an already excellent working relationship."
