Kennecott was evaluating their Eagle deposit, located in Michigan's Upper Peninsula. The deposit includes copper, nickel, gold, platinum, palladium, and cobalt mineralization and is roughly 4.1-million tonnes.
To understand if mining the deposit was realistic, in June of 2005, Stantec completed a prefeasibility study for the project. The results of our study showed that the mine could be profitable. Thanks to our study, Kennecott was ready to take the next step in mine development, feasibility level study, and they chose Stantec to help. The goal of the feasibility level study was to complete the design required to optimize the mining of the resources at the Eagle deposit.
The study identified blasthole stoping with delayed fill as the primary mining method, with a limited amount of top cut and fill mining in some areas. The need to delay recruitment of mine staff due to potential delays in securing required permits posed a risk to the project. To mitigate this risk, Stantec provided engineering, detailed design and procurement support.
