About the copper-gold Troilus Project
A Legacy of Mining, A Sustainable Future

The Troilus site has a rich mining history, operating successfully as a gold and copper mine from 1996 to 2010. Today, we are advancing a new phase of responsible resource development, focused on delivering long-term economic benefits while prioritizing modern sustainability practices.

Since acquiring the mine site in 2017, we have conducted extensive geological exploration and drilling, revealing a significantly larger copper and gold deposit than previously understood. In 2026, we completed a technical report for the Troilus Project, which incorporates the significant technical and engineering work completed since the 2024 Feasibility Study and further confirming the strong economic viability of responsibly extracting this expanded mineral resource.

Results of the 2026 Technical Report:

26 Years Mine Life
50,000 tpd conventional open-pit operation
5.63 Moz Gold LOM Payable production
427 Mlbs Copper LOM Payable production

As part of the permitting process, we are now conducting an Environmental and Social Impact Assessment (ESIA) to ensure that all environmental, social, and community considerations are thoroughly addressed. This assessment is critical in incorporating feedback from stakeholders, meeting regulatory requirements, and shaping the project’s development in a responsible and transparent manner. Learn more about the ESIA process HERE.

We are actively engaging with local and Indigenous communities, listening to concerns, sharing information, and integrating feedback into our plans. Our commitment is to work collaboratively to ensure that the Troilus Project is developed in a way that reflects community values, respects the environment, and contributes positively to the region for generations to come.

2027-2029Pre-development, construction and pre-production are expected.
The Former Troilus Mine 1996–2010:
A Journey of Community, Culture, and Positive Change

This heartfelt documentary reflects on the legacy of the former Troilus Mine, which operated between 1996 and 2010. As the site nears its final closure, the video captures emotional recollections and insights from employees - many of whom are Indigenous Crees - who played a vital role in its success. Their stories highlight not only the mine's economic and social impact but also a model of inclusive development and cultural respect in the Canadian North.
