Environmental Protection
Protecting Yukon’s environment is a long-term responsibility.
Tailings Management
We’re committed to safely managing tailings and waste rock. All materials will be stored in a purpose-built Tailings Management Facility (TMF) designed for long-term safety and environmental responsibility.
Project access includes:
- The TMF design was shaped through the Best Available Tailings Technology (BATT) Study (2016–2018), which reviewed 11 possible locations and 5 different storage methods, resulting in 498 options for the storage of mine waste and tailings at our site.
- Yukon First Nations, YESAB, and Casino’s Independent Engineering Review Panel (IERP) were actively involved in the review and decision-making process.
- Every option was carefully assessed for potential environmental impacts, community safety, and long-term risk.
- The final design goes beyond Canadian Dam Association standards and follows the Global Industry Standard on Tailings Management for best practices.
Water Quality Monitoring
- Geochemistry
Testing potential for metal leaching and acid rock drainage - Hydrometeorology
Tracking how water moves on or through the site - Hydrogeology
Tracking how the water is moving underground - Surface Water Quality
Monitoring to protect aquatic life and drinking sources - Sediment
Understanding the sediments in stream beds allow us to better understand how the water carries the minerals from our deposit, and how fish may or may not use creeks near our site
Research + Innovation in the North
The Casino Project is a proud Yukon Mining Research Consortium member, and worked in partnership with Yukon University’s Northern Mine Remediation program while it was operating to explore evidence-based approaches to mine development, operation, and closure.
Areas of research included:
- Passive water treatment
- Tailings management and remediation
- Mine site revegetation
This collaborative research helps ensure that northern projects like the Casino Project operate in alignment with community and environmental values.
Centre for Northern Innovation in Mining
Northern Mine Remediation works with Yukon University’s Centre for Northern Innovation in Mining to provide innovative and flexible training and research for Yukon’s mining industry.
Community Engagement
From early exploration to environmental review, we’ve prioritized open and respectful conversations with Yukon First Nations, governments, regulators, and community members.
- Regular engagement sessions, workshops, and meetings
- Transparent updates through public postings and community events
- Quarterly Newsletters to inform Yukoners of our Project’s progress
- Decisions are shaped by feedback from Yukoners
- We are committed to ensuring the proposed Casino Project’s opportunities and benefits stay within the Yukon and last well beyond the life of the mine.
