(k) Results were previously provided to Colorado Division -of <br />Reclamation, Mining and Safety that showed no acid or toxic <br />producing materials would be encountered during the surface <br />trenching process. <br />(1) Describe measures will be taken to minimize disturbance to the <br />hydrologic balance, prevent off-site damage, and provide stable <br />configuration. <br />• This is a very small mining / trenching operation that is typical only 6 to 10 feet <br />wide and will get refilled about every 30' to 50' so only a very limited amount of <br />trench will be opened at any given time. <br />• Trench to be backfilled and reclaimed as described in other areas of mining plan <br />plus lined with new top soil as required and replanted. <br />• Best practice of methods including Erosion Logs, Hay Bales, Erosion Nets and <br />Re -replanting of seed mixtures during back fill and road disturbances. See <br />Illustration 2. <br />• Replanting of disturbances as an ongoing process once an area has been refilled or <br />road widening completed. <br />(m) Specify whether the ore will be processed on site and nature of <br />milling. <br />• Hand sorted ore will run through the following process on-site as shown in further <br />detail in Exhibit E Map 3: <br />1. Ore is initially hand sorted. <br />2. Material is crushed down to 3/8" minus in a jaw crusher. <br />3. Jaw crusher material is loaded into a ball mill with 20 mesh screen. <br />4. Material is then loaded onto a shaker table for concentrating heavier minerals <br />that is removed for further refining. <br />5. Recirculating water supply is stored in metal water troughs. <br />6. This is a water concentration process only. No chemicals or leaches will be <br />used. <br />7. System (except for metal water troughs) is trailer mounted capable of running <br />1 to 2 tons of material per day. <br />8. Downhill portion of mill area lined with erosion control logs. <br />Teton Drilling, Inc. <br />Dixie Mine - Clear Creek County, CO <br />
