loaded direct to the portable wash plant(s) and/or stockpiled. A radial stacker may be used to convey materials from the field conveyors or 25 ton dumps to the stockpile(s). Stockpiled materials will then be used as feed stock to the portable wash plant. Tails from the wash plant will be transported back to mined-out portions of the open cast pits for use in reclamation. Mine production is assumed to be on a 350 operating days per year, seven days per week, two- shifts per day. The new portable wash plant and centrifuges have a maximum capacity of 160 cubic yards per hour. For the purposes of this study we have established a production schedule based on a nominal 120 LCY per hour, i.e., 1920 LCY/day, though OpEx is anticipated on the basis of 150 LCY per hour (2400 LCY/day). The projected annual production, including recoveries of target minerals, using a recovery factor of 80% is approximately 584,000 BCY. Recovery of placer gold, REEs, and heavy minerals will be accomplished through use of a single Oro Industries Inc. mercury-free and chemical-free mobile recovery system. Washability tests will be conducted prior to final construction of the plant. If clays and slimes are determined to be a problem in processing, a mobile scrubber trammel plant (MSTP-100) also built by Oro Industries will be substituted for the MPP-100 plant. The plant and ancillary equipment including centrifuges will be further modified and customized to the processing needs for the particular ores at the Eagle Gold and REE Placer Mine. Project infrastructure on the Timberlake Gold and REE Placer Mine include temporary crew, work, and storage buildings; roads; power systems; and water supplies and settling ponds. At least one operational water well is present on the Timberlake Nos. 1 and 2 claims. An access road exists and will be improved for prolonged and heavy operations as planned. Temporary buildings and structures (on skids, trailers, or similar) include changing and shower facilities, a 4-unit dormitory for personnel, mine offices, and lunch room facilities. A secure gold room is also included as well as security shack and core and sample storage facilities. Power can be supplied directly to the Timberlake Mine site by existing lines from Yampa Valley Electric Co. These lines and poles cross the property, but will need to be upgraded to provide the needed voltage and amperage for the plants and facilities. New transformers are also required. A 60 KW and 250KW generator will supply emergency power in the event of a power failure by the Yampa Valley Electric Co supply. The mine plan, mining method, and feasibility study replicates previous mining methods successfully used at the Timberlake Gold and REE placer deposit, Four-Mile Timberlake Creek Mining District, Moffat County, Colorado, and draws upon that mining plan and operation. A new more efficient and portable 100 to 160 LCY per hour wash plant and dual centrifuge systems, as described above, with scalper magnets will be substituted for the previous fixed- position spirals wash plant employed by the previous owners. The new plant is anticipated to increase metal recoveries by 5 to 20% over the previous plant, including potential capture of<_ - 230 mesh fine or "flour gold". The mine will operate under all MSHA defined safety rules and regulations. All employees will be MSHA trained and certified. 3
