SNC-Lavalin delivering on new strategy with Rochester POA11 project win

SNC-Lavalin says it has been awarded a contract to provide engineering, procurement and overall project management services for the Rochester POA11 project in Nevada, USA, by Coeur Rochester Inc, a wholly-owned subsidiary of Coeur Mining.

This phase of the project is estimated to be complete by October 2020, according to the company.

The project is anticipated to include a 20 Mt/y crushing plant, including a primary and secondary crushing circuit as well as a high pressure grinding roll circuit, a 13,750 gpm (52,049 litres per minute) Merrill-Crowe process plant, a new substation with power distribution and new heap leach pad.

Since approval of the initial plan of operation in 1986, the Rochester Mine has undergone periodic mine plan amendments to support mine development projects and continued operations. The mine plan amendment (termed Plan of Operations Amendment Number 11, or simply ‘POA 11’) proposes another mine life extension, which would maintain the current workforce and operate the mine at full production until 2033, SNC-Lavalin said. Coeur says it expects to produce 27,000-33,000 oz of gold and 4-5.5 Moz of silver in 2020.

The Rochester POA11 project is located 160 km northeast of Reno near Lovelock, Nevada. The Rochester mine is an open-pit operation that produces silver and gold. Mining methods include typical open-pit techniques where ore and waste rock are drilled, blasted, crushed, loaded and hauled to either leach pads (ore) or rock disposal sites.

This mining and metallurgy contract win is aligned with the company’s new strategy moving forward towards engineering services and greater growth, SNC-Lavalin said.

The Montreal-based company will provide overall project management services and integrate the engineering performed by various service providers under one set of specifications, procurement policies, standards, systems and procedures, it said. Services will be provided out of its offices in Toronto, Canada, with local support from the Reno, Nevada, branch. This mandate will include additional support such as public consultations, community engagement and working with the local community to address any impacts on the public, housing and accommodations during the project period.

César Inostroza, Senior Vice-President, Mining & Metallurgy, SNC-Lavalin, said: “As a first project with Coeur Mining, we look forward to building a long-term relationship and supporting our client to develop their silver and gold mine in Nevada.

“This mandate is well aligned with our services-based strategy for mining and metallurgy projects. This is one of multiple mining projects we have recently been awarded in the US market, and we see great potential in expanding our capabilities in the region. We look forward to contributing to our client’s project success through our extensive technical and project experience.”
