`�� 10ar7- 3 <br />carrer <br />Via Email and U.S. Mail <br />November 21, 2014 <br />/ Mr. Tom Kaldenbach <br />✓ Division of Reclamation, Mining & Safety <br />1313 Sherman Street, Room 215 <br />Denver, CO 80203 <br />RECEIVED <br />40V 2 6 2014 <br />DIVISION OF RECLAMATION <br />MINING AND SAFETY <br />Re: Schwartzwalder Mine, Permit No. 1'GI -1977 -300 <br />Water Quality Data and Mine Level Measurements for September 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 September 2014. This submittal represents continuation of <br />routine monthly reporting of water quality monitoring results, and includes data from the new <br />groundwater monitoring wells. There was not enough water in monitor well 16 to collect a <br />sample. <br />Due to malfunctioning mine pool depth probes, this submittal does not include daily mine <br />water level measurements for the month of September 2014. Data from both mine pool depth <br />probes installed by Cotter show that neither probe is responding to fluctuations in the depth of <br />the mine pool as shown by physical measurements on April 10, May 2, July 18, September 19, <br />and October 23, 2014. Alexco Corporation installed a depth probe as part of its mine water <br />treatment system, but technical difficulties have frustrated data retrieval. Cotter has ordered a <br />new depth sensor, and delivery is expected this month. The elevation of the mine pool on <br />October 23, 2014 was 6582.27 feet above sea level. <br />If you have any questions, please contact me at 719- 275 -7413 (ext. 202). <br />Sincerely, <br />C 1� 5 <br />John S.
