M-88-112 <br />Dear Steve, <br />Enclosed please find four (4) copies of a permit amendment to File No. M- <br />88-112, Battle Mountain Resources' San Luis Project. An amendment feo~ of $100.00 <br />is also enclosed. <br />The San Luis Project amendment addresses a change in ore beneficiation <br />technology which would eliminate the currently approved heap leach. Under this <br />amendment, if approved, all ore would be beneficiated through a carbon-in-leach <br />circuit in the mill facility. Disposal of the tailings will be in an engineered <br />- tailings disposal area using the thin-layer deposition method. <br />Three waste rock disposal areas have been revised. These areas have been <br />designed using the approved design standards contained in the existing permit. <br />The mine plan and permit boundary 'have not been revised anc remain as <br />approved in Permit M-88-112. <br />Each exhibit of the approved permit has been reviewed and revisions have <br />been included where appropriate to address the amendment. Upon amendment approval <br />the existing permit document will be revised to include the amended sections. <br />Your timely consideration of this amendment would be appreciated. Mr. <br />Walter Wise of Battle Mountain Gold Company is the formal conta~:t for the <br />amendment. Please feel free to contact Mr. Wise, Dean Massey or my<_elf if you <br />have any questions. <br />SincQrely, 1 <br />n ~t.~„a ~~'.~jr'.+r'1 <br />l'.h, ~'' <br />4 i <br />Anne C. 8aldrige <br />Project Manager <br />P&E <br />ACB/rje <br />Steffen Robertson and Kirsten (U.S.), Inc. <br />3232 South Vance Street, Suite 210, Lakewood, Colorado 80227, U.S.A. <br />Tel.
