Odyssey MINE

one of Canada’s largest underground gold mining projects

The Odyssey Mine, now under construction, will develop the continuity of the deposit in the Canadian Malartic and Barnat pits through four main mineralized zones at depth.

We will become one of Canada’s largest underground gold mines. We are located approximately 3 km east of the entrance to the Town of Malartic.

decree AMENDMENT

An amendment of the decree authorizing the mining of the North and South Odyssey Zones and the start of exploration ramp excavation was passed in December 2018.

Another application to amend the decree was filed with the Ministry of the Environment and the Fight against Climate Change (MELCC) in February 2021, in order to include, among other things, the East Gouldie zone, discovered in 2018, and the known East Malartic zone. We hope to obtain the authorizations for this new application in early 2022.

INFORMATION AND CONSULTATION PROCESS

As part of the application to amend the decree filed with the MELCC, an online information and consultation process was conducted in November 2020. A report on that process was incorporated into our application to the Ministry. It examines the comments, questions and concerns from citizens.
