1. Overview of the Antrim Gypsum Project
CertainTeed has successfully completed a new phase in its Antrim Gypsum Project, marking a significant milestone in Nova Scotia’s resource sector. This development follows approval from the Nova Scotia Department of Environment and Climate Change in October 2024.
2. Location and Scope
The Antrim Gypsum Project is situated approximately 50 kilometres from Halifax, near Gays River, along Lake Egmont Road in the community of Cooks Brook, Nova Scotia. The project involves the creation of an open-pit gypsum quarry that will source natural gypsum locally for the eastern Canadian and northeast U.S. markets.
3. Environmental Assessment Approval
In October 2024, the project received environmental approval from provincial authorities. This key milestone allows CertainTeed to move forward with permitting and detailed design, ensuring compliance with sustainability and environmental protection standards.
4. Project’s New Development Phase
The recently completed phase focuses on collecting essential technical data and geological assessments. This phase also allows the company to fine-tune its mine design and water management systems, preparing for large-scale operations in the coming years.
5. Construction Timeline and Future Plans
Construction of the Antrim Gypsum Project is expected to begin in 2026. Once operational, the mine will support regional construction and manufacturing industries, helping meet growing demand for gypsum-based building materials.
6. Production and Output Capacity
The Antrim mine will produce high-purity gypsum with an estimated output of 1.5 million tonnes per year. This material will primarily be used in wallboard and cement production, benefiting both Canadian and American industries.
7. Transportation and Distribution
After processing, the gypsum material will be transported by truck to an existing port facility in Sheet Harbour, Nova Scotia, from where it will be exported to various regional and international markets.
8. Economic and Regional Benefits
The project promises to boost the local economy, create new job opportunities, and enhance regional trade. With a projected lifespan of 20 years, it will contribute to long-term industrial stability and sustainable development in Nova Scotia.
9. Environmental and Sustainability Measures
CertainTeed emphasizes environmentally responsible mining, including surface miner machines for reduced environmental impact, rock processing efficiency, and water management infrastructure to minimize ecological disturbance.
10. Conclusion
The completion of this new phase of the Antrim Gypsum Project marks a major achievement for CertainTeed. With construction set for 2026, the company is one step closer to launching a sustainable and productive mining operation that will strengthen Canada’s resource and manufacturing sectors.
