Company Snapshot

Integra’s primary focus is on exploring and advancing its high-grade Lamaque South project.

Integra’s Lamaque South Gold Project and Sigma-Lamaque Mill and Mine Complex are located directly east of the city of Val-d’Or along the prolific Abitibi Greenstone belt in the Province of Québec, Canada. Québec is rated one of the best mining jurisdictions in the world1 and the city of Val-d’Or is known for its mining infrastructure, local government support, human resources and mining expertise.

The Lamaque South property is divided into three clusters, the North, South and West cluster. The primary targets are the high-grade Triangle and No. 4 Plug Deposit in the South Cluster and the Parallel Deposit in the North Cluster. The Sigma Mill, a fully permitted 2,200 ton per day mill and tailings facility which was acquired by Integra in 2014, is located 1 kilometre from the Parallel Depost and 3 kilometres from the Triangle Deposit. The Sigma-Lamaque Mill and Mine Complex include the historic Sigma and Lamaque Mines which operated for 75 and 52 years respectively and produced more than 9 million ounces of gold in total2.
