<br />Description, and labeled #1 on the Mining Plan Map. Due to [he size of <br />the open Mine entrance and the relatively shallow underground extension <br />of the developed drift in [he Mine, no ventilation shafts or facilities are <br />anticipated to be required. <br />(iv) Other. Because all of Applicant's operations aze expected to occur <br />underground, other than the loading of trucks at the Mine entrance; <br />Applicant does not anticipate the need for topsoil stockpiles, overburden <br />stockpiles, product stockpiles, waste rock fills, stream channels, etc. <br />Further, because washing and screening the lepidolite ore will occur <br />offsite, Applicant anticipates that no buildings, processing facilities, <br />ponds, impoundments, dewatering pumps, diversions, or tailing or waste <br />disposal areas will be required. To the extent that any of these features are <br />required, Applicant believes that they can be accommodated within [he <br />proposed permit boundary, subject to first obtaining appropriate regulatory <br />approvals. <br />(d) Minera/ Exlrnction. Mineral extraction will occur within the existing <br />underground drifr along the strike of the pegmatite dike hosting the Mine. The strike is roughly <br />parallel to existing surface topographic contours, and is shown in the Mining Plan Map. <br />(e) Valuab/e Su-uctures. Paragraph (b) of Exhibit B -Site Description describes all <br />of the surface structures known by Applicant to exist on and within two hundred (200) feet of the <br />affected lands. Except for the safety and reclamation values of the three grates covering mine <br />entrances, and the historic value of the core shack and ore chute, none of the structures is <br />believed by Applicant to be significant or have any additional value. The only structure <br />Applicant will impact in its operations is the grate covering the Brown Derby Mine entrance. <br />Applicant intends [o leave the grate in place during its operations, but will expand the size of [he <br />locked door providing access through the grate into the Mine. <br />(f) Ekisting Drsturbunce. <br />(i) Generally. The Mine was operated during World War II under the <br />authority of the War Production Board. During this time, mining <br />operations were conducted in an underground drift heading east from the <br />mine entrance into [he mountainside. The Mine also operated during the <br />early 1950's, during which time the operator removed overburden from a <br />portion of the underground drill, thereby turning this portion of the Mine <br />into an open pit, Subsequently, in 1990, the Office of Inactive Mines <br />installed the grate covering the Mine entrance. Applicant does not intend <br />to remove further overburden above the drift. <br />(ii) Waste Dumps. Several waste dumps were left by previous operators <br />outside the permit boundary. They are briefly described here: <br />Exhibit E - 2 <br />
