III IIIIIIIIIIIIIIII <br />999 <br />BATTLE MOUNTAIN GOLD COMPANY _ _ RECE~ I~Q <br />February 26, 1993 MAR 1 1993 <br />Mr. Larry Oehler Division of Minerals & Geolo ,~~ <br />Division of Minerals and Geology 9Y <br />1313 Sherman Street, Room 215 c~"aoco°Unn"ru"• <br />Denver, Colorado 80203 <br />Re: Battle Mountain Resources, Inc. (BMRI) - San Luis <br />DMG Permit No. M-88-112 <br />Bi-Weekly Water Sample Report - January 7-8, 1993 <br />Dear Mr. Oehler: <br />Enclosed are the analytical reports from Core Laboratories <br />for the bi-weekly water samples collected on <br />January 7-8, 1993 as specified in the April 1992 Abatement <br />Plan. The cross-reference table between sample <br />identification numbers and sample locations is attached. As <br />specified in TR-006, calculated free and wad cyanide values <br />for the process point samples are enclosed. <br />No deviations from the sampling QA/QC protocols, TR-OD6, <br />were noted for any of the samples collected. Wells M~9, <br />M-12, and M-13 and three process points were sampled. <br />RS-5 was not sampled due to excessive ice cover on the <br />stream. During the sampling event, the mill was down for <br />routine maintenance; therefore, pre-detox and post-detox <br />samples were not collected. We11s M-2, M-6, M-7, and M-8 <br />and the three lysimeter pairs were checked and found to be <br />dry. A barrel filter rinse blank, a field blank, and a <br />duplicate sample of the upper pond were taken as field <br />quality control samples. <br />Core Labs reported dissolved cadmium concentrations o$ <br />0.028 ppm at Well M-9 and 0.004 ppm at Well M-12. A13o, the <br />barrel filter rinse blank sample showed a dissolved cadmium <br />concentration of 0.013 ppm. The detected dissolved cildmium <br />concentrations appear to be from residual cadmium nitrate in <br />the barrel filter. Cadmium nitrate was used as a <br />pre-treatment during earlier sampling events to eliminate <br />sulfide interference in samples being analyzed for cyanide <br />concentrations. Alternative field filtering devices afire now <br />being used. <br />Sincerely, <br />~c:Y,a d ~-c.~~ <br />Alana L.
