Ol <br />November 02, 1998 <br />Division of Minerals and Geology <br />Department of Natural Resources <br />1313 Sherman Street, Room 215 <br />Dcnver, CO 80203 <br />Fax #:303-832-8106 <br />Attention: Carl Mount <br />RE: Permit No. M-94-117 <br />Gold Hill Mill <br />Deaz Carl, <br />This memorandum is sent with reference to the approved Technical Revision pertaining to <br />installing a layer of ballast material on parts of the exposed tailings in the original tailings <br />impoundment. The purpose, in part, is to preconsolidate those old tailings, prior to placement of <br />the remainder of the new liner system for the expanded tailings impoundment. <br />This is to confirm that, in accord with our proposal and discussions, there was incorporated into <br />the ballast material the abandoned "ore" which was removed from the coarse and fine ore bins <br />during the rehabilitation of the Gold Hill Mill. This abandoned material, estimated to have a <br />weight of 38-50 tons, was mixed with other ballast material nn October 28 & 29, 1998. On the <br />same days, the total ballast material was placed over and upon the extended geogrid <br />rcinforcetnent layer over the surface area of the exposed tailings in the two areas where the <br />indicated tailings depths exceed one foot. <br />All the abandoned material was used in this operation. At this time, the monitoring/observation of <br />settlement is in progress, and next steps await the final determination of settlement of the loaded <br />area. <br />Please let the know of any commrnts or questions. <br />ITEC Environmental Colorado Inc. <br />by, Ted ngler <br />i ' <br />~. <br /> <br />
