<br />BATTLE MOUNTAIN RESOURCES, INC. <br />February 14, 1994 <br />Mr. Larry Oehler <br />Division of Minerals and Geology anocornPAn~r <br />1313 Sherman Street, Room 215 <br />Denver, Colorado 80203 <br />Re: Battle Mountain Resources, Inc. (BMRI) - San Luis <br />DMG Permit No. M-88-112, TR-08 <br />Rc~L85t for Approval of Yiezometer Locations <br />Dear Mr. Oehler: <br />As outlined in the approved TR-16, ten additional <br />piezometers (condition 1) are to be installed prior to March <br />15, 1994. This letter serves as a request to the Division <br />to review and approve the proposed locations for the neca <br />piezometers. <br />TR-16 requires the installation of five piezometers along <br />the crest of the Phase II, Raise I embankment raise. These <br />piezometers will be identified as P11-P15 (see attached <br />location map). The approximate proposed coordinates for thz <br />embankment piezometers are: <br />P11 N 205,275 <br />E 2,037,760 <br />P12 N 205,460 <br />E 2,037,700 <br />P13 N 205,650 <br />E 2,037,635 <br />P14 N 205,855 <br />E 2,037,570 <br />P15 N 206,065 <br />E 2,037,500 <br />A schematic of the embankment piezometers is enclosed; this <br />design is consistent with the 8590' embankment piezometers <br />installed in September 1993. As outlined in the Division's <br />November 2, 1993 letter, the screened portion of the <br />standpipe will be located at or near the base of the fill. <br />BMRI proposes that the piezometers will be constructed such <br />that the bottom cap is at or near the contact of the <br />embankment fill material and the tailings with a l0' screen <br />interval in the fill material directly above the cap. <br />,1 S(1fl5lOh1RY OF RA'171.1. 110//.Yl:1/N G(1/ /) COMPANY <br />P.O. 60X !IU SAN LU lS.CQLORADO S11S'_-010 (7IH16T_336'_ FAX {7141 b71~3363 <br />
