Gibraltar’s Reclamation Research Programs

The aim of Gibraltar’s reclamation research program is continual improvement by identifying and

introducing leading-edge ideas within the field of environmental science in min e reclamation. With this

goal in mind, projects at Gibraltar include:

• sampling of salmon from the Fraser River in partnerships with the Xatśūll First Nations and the North

Shuswap Tribal Council to provide information to local Indigenous communities regarding the safety of

consuming salmon captured at traditional fishing sites

• studying and utilizing innovative technologies to determine how reclama tion activities promote the

development and recovery of biological communities;

• supporting BCIT, SFU, and Mitacs master’s students in a trial research program to expedite the

development of soil microbial crust, specifically at the tailings storage facility.
