the access road gate will also be locked to prevent unauthorized access. Inspections will be done on <br />all underground chemical storage once every 2 weeks. <br />7. Facilities Evaluation <br />Maps and drawings describing the underground mill layout are given on 7 drawings provided by <br />Samuels Engineering, which are included in Appendix 7. <br />7.1 Mill Description <br />Crushing <br />Mined ore from the main mine tunnel will be arriving at the mill dump point via rail cars. The rail <br />cars will be dumped into one of two hoppers depending on the ore materials source. (The hoppers <br />will have a 12 inch grizzly on top with a rock breaker to prevent oversize material from entering the <br />plant.) After the ore is in the hopper it will be pulled out using a feeder and be placed on a 48 inch <br />wide belt conveyor. Over the belt conveyor will be a magnet for removal of tramp iron from the <br />feed, which can damage the crushing equipment. The belt conveyor will feed a Metso C80 jaw <br />crusher. The jaw crusher will crush the material from 12 inches to 1.5 inches. The product from <br />the jaw crusher will be sent on a 24 inch wide conveyor to a horizontal FLSmidth 5x16 screen. <br />The inclined screen will sort the material into two size fractions with a separation point of 3/8 of an <br />inch. All the material smaller than 3/8 of an inch will be sent to a fine ore bin. All the material <br />which is coarser than 3/8 of an inch will be sent via a 24 inch conveyor to a Nordberg 3 foot short <br />head cone crusher. The cone crusher will crush the feed material to 3/8 of an inch or finer. The <br />product from the cone crusher will be combined with the jaw crusher product on the 24 inch belt <br />conveyor and brought to the screen for size separation. <br />Grinding Circuit <br />The material from the fine ore bin will be pulled out using a scaled belt feeder to ensure accurate <br />ball mill feed tonnages. The material will be fed into a 8 foot diameter and 12 foot long ball mill <br />which will grind the feed material to eighty percent passing 150 mesh. The ball mill will grind in <br />Revenue Mine August 2012 T -26 <br />
