The New Brunswick government wants to reopen a historic mine just south of Fredericton. Officials launched a competitive process to find a private company willing to explore and develop the former Lake George antimony mine. This site sits about 30 kilometres southwest of the capital and offers massive economic potential for the province.

The Value of Antimony

You probably do not think about antimony every day, but it powers the technology you rely on. Manufacturers use this shiny grey metal as a flame retardant and in solar panels and lead acid batteries. The defense industry also relies on it to build infrared missiles, nuclear weapons, and night vision goggles. Canada, the United States, and the European Union all classify antimony as a critical mineral. Right now, global supply is heavily concentrated in China. The provincial government sees the Lake George site as a way to secure a reliable domestic source for these essential materials.

A Billion Dollar Opportunity

Lake George previously operated as North America’s largest primary antimony mine between 1876 and 1996. A historical technical report estimates the site still contains about 800,000 tonnes of antimony bearing ore. At current market prices of $22 per pound, that ore holds an estimated value between $933 million and $1.05 billion. The site also contains tungsten and molybdenum.

Natural Resources Minister John Herron highlighted the importance of the project. “In today’s economic and geopolitical climate, the need for secure, responsibly produced critical minerals has never been greater,” Herron said. He added that New Brunswick is well positioned to meet demand by attracting investment and strengthening partnerships with Indigenous communities.

The Bidding Process and Next Steps

The current expression of interest process is nonbinding. The government refuses to assign any mineral rights until a formal exploration agreement is reached. Officials evaluate submissions based on technical expertise, financial capacity, and a commitment to working with Indigenous communities. Any future mining activities require strict regulatory and environmental reviews.

Broader Mining Push

This announcement aligns with a larger push for critical minerals in New Brunswick. The province also supports the development of a tungsten mine near Sisson Brook. Prime Minister Mark Carney recently confirmed the Sisson project is part of a federal initiative to expedite reviews for nation building infrastructure.
