The proposed project includes a four year construction period and a 90 year post-closure period. Key project components include the open pit, tailings management facility and waste rock storage area, heap leach facility, mill and associated infrastructure, ore stockpiles, liquefied natural gas power generating infrastructure, and office and accommodation buildings. The project also requires a 120 km access road from the town of Carmacks, YT, and concentrate will be trucked to the port at Skagway, Alaska. The Casino Mine Project is a proposed 22 year mine project owned and operated by Casino Mining Corporation (CMC), that will produce copper and molybdenum concentrates, and gold dore bars via flotation milling and heap leach processing, respectively. The location of the Casino Project is shown on Figure 1 1. Key project components include the open pit, tailings management facility and waste rock storage area, heap leach facility, mill and associated infrastructure, ore stockpiles, liquefied natural gas power generating infrastructure, and office and accommodation buildings. The project also requires a 120 km access road from the town of Carmacks, YT, and concentrate will be trucked to the port at Skagway, Alaska. LNG is proposed as the primary fuel supply for power generation and other ancillary uses at the Casino Project. All LNG deliveries to the mine will be by truck transport that will ramp up to an estimated 900 m3/day LNG when at full production. LNG storage is required at the mine to stockpile sufficient inventory to supply natural gas fuel needs during the period where road access is limited due to weather. A management plan for toxic or hazardous substances is required by the Canadian Environmental Protection Act (CEPA) and through the Environmental Management Act (EMA) Hazardous Waste Regulation. Prior to the start of operation, a comprehensive LNG Management Plan for the Casino Project will be developed to ensure worker safety and to prevent uncontrolled releases to the environment. The LNG Management Plan will be developed in consideration of the principles and standards of practice of the Canadian Standards Association (CSA) standards CSA-Z276, CSA-Z731 and the National Fire Protection Association (NFPA) codes NFPA 59A, as well as other principles and standards of practice related to transportation, handling and storage/use and worker safety and emergency response.
