M- 2013 -070, LIBERTY MINE, LIBERTY MINING, LLC. MESA <br />COUNTY, QUARTERLY-GROUNDWATER MONITORING <br />Dear Mr. Marshall: <br />On behalf of Liberty Mining, Souder, Miller and Associates (SMA) is notifying the Colorado <br />Division of Reclamation, Mining & Safety that the fifth quarter of five total required quarters of <br />groundwater monitoring was completed at the Liberty Mine, Mesa County, Colorado. The <br />groundwater monitoring event included gauging levels in monitoring wells MW -1 and MW -3 <br />and sampling of MW -1. <br />On March 6, 2014, SMA representatives visited the site for the quarterly groundwater gauging <br />and monitoring event. The depth to water in MW -1 was 498.55 feet below top of casing. The <br />MW -1 depth to water following the monitoring event of November 14, 2013 was 496.9 feet, <br />indicating no recovery over the nearly four month period. <br />Similar to the previous quarters of monitoring, the total depth of MW -3 was measured at 256 <br />feet below TOC. MW -3 did not contain measurable water. <br />On March 6, 2014, SMA collected water from MW -1 using a disposable bailer. Approximately <br />1.8 gallons of water was purged from the well during the sampling event, dropping the water <br />level to 501.33 feet below top of casing. The well could not be completely purged with a bailer <br />due to high sediment content and the depth to water. <br />The water was sampled for the following items: <br />• EPA Method SW -846: Metals <br />• SM20 2340B: Total Hardness Calculation <br />• EPA Method 300: Chloride, Fluoride & Sulfate <br />• EPA Method 353.2: Nitrate, Nitrite, Nitrate +Nitrite <br />• SM20 4500 -PE: Total Phosphorus <br />• Carbonate, Bicarbonate, Alkalinity <br />• SM2 450OH /SW 9040: pH <br />• SM20 251 OB:Specific Conductance <br />• EPA Method 160.3/SM20 2540C: Total Dissolved Solids <br />• SM 711 OB: Gross Alpha /Beta <br />RECEIVE® <br />APR ''2 9 2014 <br />DIVISION OF '2ECLAMATION <br />MINING AND SAFETY <br />Engineering • Environmental • Surveying www.soudermiller.cum <br />
