Gold to Green Collaboration: Mining Company and Energy Firm Team Up for Renewable Energy Project in Nova Scotia

A mining company based in Nova Scotia is considering converting one of its closed gold mines into a hydro energy storage system and a solar farm. Atlantic Mining ceased operations at the Touquoy gold mine in Moose River last year and recently introduced a new proposal for the site. Partnering with Halifax-based renewable energy company, Natural Forces, a feasibility study is underway to explore the development of a “renewable energy hub” at the mine.

The Renewable Energy Hub

The plan involves utilizing the mine’s open pits to create a closed-loop pumped hydro energy storage system. This innovative system utilizes two connected water reservoirs, with one reservoir positioned higher than the other. During periods of low demand on the grid, excess power is used to pump water to the upper reservoir. Conversely, when energy demand is high, water is released from the upper reservoir through a turbine to generate electricity and supply the grid.

This concept provides a sustainable way to repurpose the existing infrastructure of the mine while utilizing natural resources to store and generate energy. Amy Pellerin, the director of Canadian development at Natural Forces, emphasized the potential benefits of leveraging the elevation difference and reservoir already present at the mine site.

The feasibility study will also evaluate the construction of a solar energy project on the mine’s waste rock pile, further contributing to the renewable energy initiatives at the site.

Land Reclamation and Environmental Considerations

Andrew Strelein, the managing director and CEO of Atlantic Mining, highlighted the company’s dedication to sustainable development through this initiative. As part of the mine closure requirements, land reclamation efforts will be integral to the project. The feasibility study will address the reclamation process, ensuring environmental considerations are prioritized.

While the project showcases innovative approaches to green energy development, concerns have been raised regarding Atlantic Mining’s environmental track record in Nova Scotia. Environmentalist Karen McKendry expressed caution due to past breaches of environmental laws by the company. However, McKendry acknowledged the potential of the project and emphasized the importance of transparent details regarding how it aligns with the mine’s reclamation objectives.

Shift in Operations and Future Plans

Originally, Atlantic Mining had intended to use the Touquoy site for processing gold from the Fifteen Mile Stream project. However, plans have evolved, and the company now aims to consolidate all operations at the Fifteen Mile Stream site. A new environmental assessment application for the Fifteen Mile Stream project is anticipated by the end of the year, coinciding with the conclusion of the feasibility study for the Touquoy repurposing project.
