®Cameo L'E <br /> Via Email and U.S. Mail <br /> July 18, 2014 RECEIVED <br /> ,Mr. Tom Kaldenbach VJUL ? 2 Z014 <br /> Division of Reclamation, Mining& Safety <br /> �' 1313 Sherman Street, Room 215 Division at i�tecearnation, <br /> Denver, CO 80203 Mining Safety <br /> Re: Schwartzwalder Mine, Permit No. M-1977-300 <br /> >Jater Quality Data for April 2014 and Adjusted Mine Level Measurements for February- <br /> April 2014 <br /> Dear Mr. Kaldenbach: <br /> With respect to the Schwartzwalder Mine site, enclosed please find monthly water quality <br /> monitoring results for the month of April 2014 (with certain data collected on May 1, 2014), <br /> and adjusted daily mine water level measurements for the period February through April <br /> 2014. This submittal represents continuation of routine monthly reporting of water quality <br /> monitoring results and daily mine pool levels. It includes data from the new groundwater <br /> monitoring wells. There was not enough water in monitor well 16 to collect a sample. <br /> The new cable was received and the new water level probe was placed in the shaft on April 10, <br /> 2014. A physical measurement of depth to water was made at that time, showing the mine <br /> pool surface at 23.05 feet below the Steve collar or 6,578.89 feet in elevation. <br /> In February 2014, when the old probe started to produce erratic results, an attempt was made to <br /> withdraw the probe. The attempt was not successful. After the new probe was installed in <br /> Shaft#2, an attempt was made on April 17, 2014 to bring the new probe up out of the shaft, <br /> and that attempt was unsuccessful. These activities resulted in the probe ending at different <br /> elevations on February 27, April 10, and April 17, 2014. Accordingly the attached mine pool <br /> water levels have been adjusted to account for these changes in probe elevation referenced to <br /> the measurement made on April 10, 2014, and cover the period February through April 2014. <br /> Cotter Corporation Telephone(719)275-7413 <br /> Canon City Mill,P.O.Box 1750,Canon City,CO 81215-1750 USA Fax(719)275-1669 <br />
