Agnico Eagle Mines Ltd. has proposed the Whale Tail Project, approximately 130km North of Baker Lake, NU. The project includes the construction a dyke within Whale Tail Lake that will divert water from the proposed mining pit into the surrounding lakes and tributaries, resulting in flooding that will elevate the water levels by 4 m above current levels over two years, causing approximately 157 ha of tundra to become flooded during the time of birds? nest initiation.
The Hamlet of Baker Lake, Nunavut has experienced unprecedented development with the construction and opening of Agnico-Eagle’s Meadowbank gold mine, 100km away by all-weather road. As Meadowbank is the first mine to be established in Nunavut since the creation of the territory in 1999, the community of Baker Lake serves as a test case for the rest of the territory.
The recovery of gold from its ores normally involves a leaching process with cyanide, resulting in the formation of gold cyanide along with a range of other metallocyanides from the crude ore. Therefore, monitoring of the different cyanide species at various stages of the process and in waste solutions is crucial for providing the optimal conditions for the leaching procedure and for environmental protection. AEM wishes to extend the recently developed protocol (or develop new one(s)) in order to analyze the speciation of Zn, Ni, Co, As and Sb complexes in the cyanidation process water.
