1 Hayman, Randy -FS Subject: Attachments: FW: CuMo Mine Objection thompsoncreekmolybdenumminearialview.pdf; Thompson_Creek_mine.jpg; Mo_processing_flow.gif From: Mary Heyn Sent: Wednesday, June 24, :56 PM To: FS-objections-intermtn-regional-office Subject: CuMo Mine Objection Dear Forest Service Staff, This is my second letter of objection (first letter sent 9/18/2014) to the proposed huge molybdenum, copper, and silver mine proposed to open in Boise County, 3 miles NE of Grimes Pass at T-8N R6E section 7,8, 17, 18,19, 20; by CuMo Mining. I have and still have very grave objections to this proposed mining proposal. This information was taken from CuMo's own website: This proposed site may be the country's largest deposits of Molybdenum, copper and silver. I stand in sincere objection on every front to this proposed mine and development due to the following: 1. Loss of a whole mountain top to an extremely ugly open pit mine. Please see picture attachments below of the Thompson Creek open pit mine located near Stanley, Idaho. I Do Not Want This Kind of Mine in my Backyard! I Do Not Want This Kind of Mine in my Backyard! I Do Not Want This Kind of Mine in my Backyard! 2. Watershed pollution. The CuMo people relayed that there would be no Arsenic but due to the very nature of Molybdenum mining there would be polluted water and polluted catchment ponds from the mining and extracting procedure itself with subsequent concentrated high levels of poisonous mining residues. It is a crushing, grinding, and flotation (with water) mining procedure employing trommel (grinding) and highbanker (water) methods. Where will CuMo mine obtain this kind of water for their mining operations? This would surely cause catastrophic implications for Grimes creek, the Payette River, and the Boise River watersheds. The CuMo mine can not verify nor offer any rational explanation that there will be no watershed damage. There will also be a huge impact with the large equipment plus the mining traffic, noise, and pollution of every kind. Please see attachment below regarding Molybdenum mining. I was unable to open the Environmental Impact Statement~why is this the case? The 300,000 Bond that Cu MO mine put up is no where big enough for environmental clean up let alone any disaster which can and will probably occur. The CuMo mine will create 99 tons of waste for every ton of Molybdenum extracted. Where does CuMo mine propose to put all the waste product during and after exhausting the mine of Molybdenum and other minerals (copper,silver) for a period of a 100 year longevity? 3. Complete Loss of Biodiversity-actually the Mountain will be stripped bear. There will be no standing forest with under-story and thus there will be no habitat for any creatures big or small. All living organisms will either be destroyed or forced to move to other locations. I Do Not Want This Kind of Mine in my Backyard! There will be epic soil erosion and water pollution. I will no longer be able to visit this beautiful spot to hike and camp with my family and friends. 4. Job creation? CuMo mine has proposed big economic incentives of jobs, taxes, and growth. 1

2 I would like to ask CuMo mine how many local residents they plan on hiring or will most employees come from other locations? I believe that job and economic growth can come from somewhere else that doesn't destroy the environment in it's wake. 5. Everything stated on CuMo company website sounds 'too good to be true' and I firmly believe that CuMo Mine is 'too good to be true' and CuMo's proposed slick plan should not be believed, stopped in it's tracks, and not allowed to go one step further. For the Mountain's sake~ Sincerely, Mary Heyn Mary Heyn 1254 Cumberland Dr. Boise, Id

4 Thompson Creek Mine The Thompson Creek Mine is a primary molybdenum mine located in mountainous terrain with an open pit, mill and tailings facility. It is the fourth-largest primary molybdenum mine in the world. The property is approximately 35 miles southwest of the town of Challis in Idaho s Custer County, a historic mining area. The mine, which began operations in 1983, uses conventional open-pit mining methods with large electric-powered shovels that can each move up to 100,000 tons of waste rock and ore per day. The shovels load ore into 200-ton trucks to be hauled to an on-site mill (concentrator). A molybdenum disulfide concentrate is extracted from the ore through a series of crushing, grinding, and flotation operations. Daily throughput of ore at the mill has recently averaged close to 28,000 tons per day. Most of the molybdenum disulfide concentrate produced at the mine is further processed into technical grade molybdenum oxide at the Langeloth Metallurgical Facility in Pennsylvania. The current mine plan is based on the mine life calculated in 2007 at approximately 10 years, assuming a molybdenum price of US$10 per pound and updated costs. During 2008, Thompson Creek conducted development drilling beside and below the current ore body. The drilling results are currently being evaluated. 55 Boise mi Thompson Creek Mine 21 Stanley Clayton Carey Challis Custer County A molybdenum disulfide concentrate is extracted from the ore through a series of crushing, grinding, and flotation operations Thompson Creek Mine Cross Section W 8,000 ft.
