i Dr. James Pendleton ~ . August 14, 1992 Page 3 the Mined Land Reclamation Division and will deliver the appropriate sam le containers and deionized, distilled water supplied by the analytical laboratory. Under WWL oversight, personnel of Battle Mountain Gold or their contractors will responsible far operating all sampling equipment, obtaining the sample and fillip the sample containers supplied for the split samples. It is expected that water qualit samples will include quality control samples consisting of field duplicates, field bla ks and rinse blanks collected according to the prescribed schedule. A standard sam le of known cyanide concentration will also be periodically submitted in a blind anner to the laboratory. Sampling activities are estimated to be completed in appr imately one day. All pertinent field activities and observations during the sampling vent will be recorded, chronologically, in a hard-bound field book. Chain-of-cu tody forms, received from the laboratory at the time the sample containers are obt fined, will be maintained throughout the sampling episode. Following sampling, the sample containers will be transported to the selected analytical laboratory ccording to documented protocols. While the list of laboratory parameters to be ana yzed for the spilt samples has not been specified at this time, it is expected that the p rameters to be analyzed will, at least, include cyanide and selected metals.

Post-Samolino Activities and Reporting The results of the laboratory analyses will be evaluated to verify the va data. The data verification will include evaluation of quality control sat (duplicate, rinsate and blank samples), calculation of the major ion balance calculation of the cyanide balance, and comparison of the data to previo results. Any water quality data that exceeds control criteria will be noted of compliance and the laboratory will be contacted. The sampling rea summarized in a brief narrative report for submittal to the Mined Land Division. Any analyses that are determined to be out of compliai documented in the report. In addition, the narrative report will provide ci sampling procedures, a copy of the sampling checklist and field notes, ar the laboratory analyses report and all documents related to the sampling Project Manager 4 hours @ 570 Project Engineer 24 hours @ S55 1 Misc.
