Boye, L. Colby, Z. Felkey, K. Blake <br /> • Jofree Duran <br /> • - TR 113—Leach Study_Cell <br /> This document summarizes the geotechnical evaluation of the proposed leach study cell (cell)that <br /> is planned to be located at the Arequa Gulch Valley Leach Facility(AGVLF). <br /> The proposed cell will be staked to the 10,165 ft elevation, and will have a lift height that varies from <br /> 2 ft at the southern edge to 35 ft at the northern edge. It will be lined to allow the collection of <br /> leached solution (see Figures 1 and 2). <br /> The cell will have a minimum set back of 20 ft from the edge of the existing bench. The bench <br /> below the cell has a bench width that varies from 115 ft in the section where the cell has a height of <br /> 2 ft, and 257 ft in the section where the cell has a height of 35 ft. <br /> The ore material to be placed in the proposed study cell is composed by hard ore with similar <br /> strength properties of the crushed ore and given the geometry of the cell, it's limited height, and it's <br /> location on the AGVLF, the proposed cell is considered stable. <br />
