<br />Letter to Ken Kluksdahl <br />Third Party Monitoring Report #1 <br />page 2 <br />Monitor had several discussions that refined the scope of the report. <br />This and all of the previous delays led to changes in tha MOU and in <br />the contract. <br />Battle Mountain has voiced concern about the analysis :reported for <br />total cyanide in well MW-13. The analysis of monitorinc{ well MW-13 <br />indicates that Total Cyanide is present at the level of 0.03 mg/L. <br />This is 0.01 mg/L above the detection limit of 0.02 mg/L, A split of <br />this sample, collected by BMRI and submitted at the same time to the <br />same laDOratory indicated detection at less Lhan 0.02 mgjL. The <br />practical quantitation limit for this parameter is indicated to be 0.10 <br />mg/L. In other words, the level at which cyanide can be reliably <br />determined is approximately 5 times higher than the level at which it <br />car. be detected. the Division will not act on the basis of a report <br />such as this unless the PQL is exceeded. <br />Bi ,~i~i :,motes that because sample i:,~ttles from i,iyi, cya„ide px,~c~ss psi„i.~ <br />ware mixed in transit with sample bottles from low cyanide process <br />points, there was a breach of protocol, and therefore the analysis <br />reported for MW-13 may represent contamination. The Division concurs <br />with this assumption; the third party monitor has taken steps during <br />subsequent sample shipments to assure that no cross-contamination will <br />occur in this fashion. <br />As a result of the Division's and Battle *".ountain's review c:f the firsr <br />report, changes have been made in the Memorandum of Understanding <br />between Battle Mountain and the Division. In addition, the contract <br />betweer. the third party monitor and Battle Mounta_a was r.:odified. <br />Likewise, changes have been made in tP.e samplina_ and analytical <br />protocol, TR-006. <br />The Division appreciates the cooperation of Battle Mountain and the <br />assistance of RCG/xagler-Bai11y in this effort. Tree also ~pFreciate the <br />patience of the community of San Luis, for whom this report has been <br />long delayed. <br />Please distribute the required copies of the report for public <br />examination. <br />Persons with questions or comments should address those to Harry Posey <br />at the Division of Minerals and Geology (303J866-3567). <br />
