M-88-112 <br />Dear Mr. Oehler: <br />In compliance with Abatement Items 8 and 10 of the 1942 Notice of ViolatioE~ issued to Battle <br />Mountain Resources, Inc. (BMRI), we are pleased to provide you with thr copies of the <br />enclosed Reclamation Evaluation. <br />Abatement 8 required BMRI to evaluate the tailings chemical constituents to (determine if the <br />potential differences in metallic content of the ore and chemical changes in interim and final <br />detoxification procedures rendered the approved reclamation plan for the !, tailings facility <br />inappropriate. If changes to the reclamation plan were necessary, then Abatement 8 required <br />BMRI to submit comprehensive analytical results and design evaluations to the ivision no later <br />than 180 days after completion of the cyanide detoxification of the tailings ar contents. <br />The 180 day time frame was initiated November 15, 1992. This smittal includes <br />comprehensive information on BMRI's evaluations of the tailings chemical onstituents. In <br />addition, this submittal also include BMRI's evaluations of other tailings ch cteristics which <br />could affect the long-term reclamation planning such as tailings consolidatiorh and long-term <br />reclamation planning such as tailings consolidation and long-term seepage m efing. Finally, <br />the document evaluated the Division's predictions of movement of the high cy ide pore water <br />through the tailings material. <br />As discussed in the document, none of the comprehensive information gQthered for the <br />evaluation indicated that the characterization of the tailings material as non-tozi and chemically <br />inert is inappropriate. In addition, the assumptions of long-term tailings geochemistry, <br />consolidations and underdrain performance which were utilized to develop the approved <br />reclamation plan have not changed as a result of the changes in tailings detoxification. <br />A SC~RSIDIAFY OF BATTLE.
