EXPLORING WAYS TO IMPROVE CHINOOK SALMON HABITAT

Source: Casino 2015 Spring Newsletter

Casino is exploring ways to improve habitat for Yukon River Chinook salmon.

Juvenile Yukon River salmon spend the first year of their lives in freshwater habitats that provide food and protection from predators, and conditions suitable for surviving the winter. Good conditions in this first year of life are critical for preparing fish for the long and arduous journey ahead, as Yukon River Chinook salmon are notable for having some of the longest salmon migrations in the world.

As part of the environmental assessment and permitting process, Casino is working with project partners, including Selkirk and Little Salmon/Carmacks First Nations and Tr’ondëk Hwëch’in to identify options to improve Chinook salmon freshwater habitat.

One opportunity being explored is the reinstatement of a historical watercourse channel adjacent to the Yukon River, just north of the Casino property. If restored, the channel would provide new high-quality habitat for Chinook salmon seeking early-life refuges.

COPPER-HUNGRY MICRO-ORGANISMS AT CASINO

Casino has partnered with Simon Fraser University, Palmer Environmental Consulting Group and Genome BC to study micro-organisms found in upper Casino Creek near the Casino deposit. The research will evaluate how these microbes are incorporating copper into their cell structure and how this process affects the amount of copper observed downstream in Casino Creek.

Research findings suggest there is already a naturally occurring process of metal removal from the water, and study results may contribute to Casino’s proposed long-term, passive water treatment plan for the Tailings Management Facility.

METAL UPTAKE IN NORTHERN MAN-MADE WETLANDS

This past spring, Casino partnered with the Yukon College: Yukon Research Centre on an applied research project that will evaluate potential uptake of heavy metals in selected northern wetland plant species.

Research results will help to mitigate concerns of heavy metal uptake by plants in the Casino project area and the spreading of contaminants into the environment through wildlife.

The research will also inform the Closure and Reclamation Plan of the proposed Casino Mine’s Tailings Management Facility. It aims to use constructed wetlands as a passive, long-term care solution for the treatment of open pit water overflow and tailings  effluent.

“This project further reflects our commitment to using the highest possible standards and supporting innovation in mine remediation technologies in the north,” said Casino President Paul West-Sells.
