The New Brunswick government is taking major steps to restart extraction at the former Lake George antimony mine. This move targets a mineral the federal government labels essential for national security. If you follow local industry, you know this site once stood as North America’s largest antimony producer. Now, the province wants to bring it back to life.

Partnering for Exploration
Officials selected Avenir Minerals to lead the exploration agreement. Avenir operates as a subsidiary of the Canadian firm Agnico Eagle Mines. According to a recent report from Global News, the two parties will finalize the agreement over the next few months. Avenir Minerals CEO Alden Greenhouse confirmed the company plans to collaborate closely with the province, local communities, and Indigenous Peoples throughout the process.
The Importance of Antimony
You will find antimony in everyday products like flame retardants and lead acid batteries. Beyond everyday use, Canada, the United States, and the European Union classify it as a critical mineral. Currently, global supply relies heavily on China. Western governments want to build domestic supply chains to secure these resources. This renewed interest gives New Brunswick a prime opportunity to revive its mining sector and boost the local economy.
