Nelligan Mining Complex

Québec, Canada · Open Pit

Under Development
Gold
Overview
The Nelligan project is a large-scale, open-pit gold exploration project located in the Nord-du-Québec region of Québec, Canada. It is situated approximately 60 kilometres southwest of Chibougamau and 45 kilometres south of Chapais. The project is fully owned and operated by IAMGOLD Corporation. The company has consolidated its land position in the Chibougamau district, combining the Nelligan project with the nearby Monster Lake, Philibert, Chevrier, and Croteau projects to form the Nelligan Mining Complex.
Processing
Preliminary metallurgical test work suggests a processing flowsheet incorporating flotation with regrinding could improve gold recovery compared to direct cyanidation of the whole ore. One study indicated a sulphide flotation circuit followed by cyanidation and carbon-in-leach could yield a gold recovery of about 92%. An optimal flow sheet has not yet been selected.

Workforce
640 people, comprising 290 unionised workers, 110 employees, and 240 contractors.
Overview
The mine is located in northern Mexico in the state of Coahuila, approximately 708 kilometres northeast of Torreon. The property is situated in the municipality of Villa de Ocampo, about 120 kilometres east of the city of Melchor Múzquiz. The site includes 4,076 hectares of mining rights and 1,343 hectares of surface rights.
Production
In 2023, the mine processed 966,392 tonnes of ore, producing 2,718,856 ounces of silver and 321 ounces of gold. In the fourth quarter of 2024, the mine produced 755,963 ounces of silver from 253,953 tonnes of processed ore. The projected production for 2024 is 2.3 million ounces of silver.
Processing
Historically, a 1,000 tonne-per-day flotation plant was the primary method for silver recovery. This was later replaced by a 4,000 tonne-per-day cyanidation mill. The flotation circuit was suspended in June 2010 and is currently under care and maintenance. The cyanidation plant, which commenced operations in April 2010, allows for the production of silver doré bars on-site.
Equipment
electro-hydraulic jumbos, hand-held jacklegs, diesel-powered load-haul-dumps (LHDs), highway-type diesel rear-dump trucks, battery-powered rail haulage trains, three new 20-tonne Torino-style haulage trucks with Mercedes-Benz engines
