1, , <br />III II~'llllllllllll <br />{-. _ <br />. ] i. ,i_, <br />BATTLE MOUNTAIN RESOURCES, INC. <br />August 30, 1993 <br />Mr. Larry Oehler ~~-~(!• ,f <br />Division of Minerals and Geology - ~EM~+~+ <br />1313 Sherman Street, Room 215 q 3.~3 DCOMPANV <br />Denver, Colorado 80203 I~.- <br />Re: Battle Mountain Resources, Inc. (BMRI) - San Luis <br />DMG Permit No. M-88-112 <br />Bi-Weekly Water Sampling - July 10, 1993 <br />Dear Mr. Oehler: <br />Enclosed are the analytical reports from Core Laboratories <br />for the bi-weekly water samples collected on July 10, 1993 <br />as specified in the April 1992 Abatement Plan. Core Labs <br />issued the reports under two separate job numbers; both sets <br />of data are enclosed. The cross-reference table between <br />sample identification numbers and sample locations is <br />attached. As specified in TR-006, calculated free and wad <br />cyanide values for the process point samples are enclosed. <br />.~ iyg~ <br />No deviations from the sampling QA/QC protocols, TR-006, <br />were noted for any of the samples collected. Wells M}9, <br />M-12, and M-13 were sampled. Samples were collected at ff° <br />surface water station RS-5. Four process points were ;~`~ <br />~ <br />~ <br />sampled; the pre-detox sample could not be collected ~iue to <br />maintenance activities. Wells M-2, M-6, M-7, and M-8 and ~,~,~~ <br />- <br />` <br />;~ ~°(/ fi~y :~!~~ <br />the three lysimeter pairs were checked and found to be dry. ~I,,gi•z~` <br />1 <br />The initial analysis by Core Labs of the cyanide samples for <br />the upper, lower, and collection ponds showed CN-wad values <br />greater than CN-total values. The samples were re-analyzed. <br />Both reports are attached. All cyanide values were below <br />our permit limits. <br />The analytical results for the post detox sample <br />(930710 BMG OS) appear to be anomalous. The cyanide <br />(total and wad) concentrations reported by Core Labs $or <br />this sample were at the detection level of 0.02 ppm. This <br />concentration is unusually low for a post detox sample. <br />The July 10 post detox sample analyzed on-site showed <br />0.95 ppm CN-wad and 1.12 ppm CN-total. Also, the zinc <br />concentration of 0.14 ppm is elevated from the range of <br />0.01-0.03 ppm that has been established over the past nine <br />months of INCO post detox sampling. Since both the metals <br />and the cyanide results are in question, the sample may have <br />been contaminated during collection. <br />A SUHSIOIAHY OF HATTLF, .NODNTAL~' GOLD CO~IPANY <br />P.O. BOX 31U SAN LUIS, C'OLOHADO NI IS?-0310 1719) 672-336? FAX 1719) 672-3367 <br />
