Proponent: Marathon Gold Corporation
Summary of Environmental Assessment Process
Project Description:
The proponent is proposing to develop a gold mine approximately 55 kilometres southwest of Millertown in the central region. The project includes four potential mining deposits: Leprechaun, Sprite, Marathon, and Victory deposits. Standard surface mining techniques will be used in open pit construction and operation. The project will involve waste rock disposal piles; crushing and stockpiling areas; heap leach processing; conventional milling; processing facilities; and tailings management areas. It will require personal accommodations and supporting infrastructure including roads; power lines; buildings; and water and effluent management facilities. The construction period is expected to last 18-24 months followed by an estimated mine operation life of 13 years. The project will operate 24 hours per day, seven days a week on a 12-hour shift basis.
