Dear Mr. Douchane: As you know, the Board directed the Division to report at the July Board meeting on its "beliefs" regarding BMRI's efforts to bring down the cyanide levels in the tailings ponds. To accommodate their directive I wish to request as complete a copy as you have of all the pond samples from just prior to HzO: addition to the present. I understand from talking with you today that you have all of the data on a spreadsheet, and that you may be able to print out the data in graph form. At a minimum I could use the following: 1. All free, WAD and Total Cyanide data from each of the several analytical labs. These should be segregated according to the pond from which the samg~les were collected. (If you are missing data from samples that the Division collected, please let me know.) 2. A bar or line graph showing the trends for each of the various labs' analyses. ZWhat we want to know here is that Battle Mountain's internal monitoring. is at least fairly consistent with external labs.) 3. An estimate of the amount of HZO, added daily to date, and the approximate cost. (I doubt we will provide this data to the Board unless asked.) We hope to present data at least through Friday, July 17. More would be useful, if possible. In either case, we will need the information by mid-day, June 20.
