1 <br /> CURRENT CONDITIONS <br /> Map Exhibit C shows the outline of the effected lands, touching land <br /> ' owners, vegetation and current topography. <br /> Except for the existing mining areas, land use has been and will continue <br /> ' to be limited to habitat for non-critical wildlife on the hogback and occasional <br /> ' pasture in the lower flatter areas. <br /> The majority of the mining in this area has been from underground stopes. <br /> Many of these stopes have been mined to the surface so there are numerous <br /> openings along the crest of the hogback. Some of these openings have caved <br /> ' in, however, the majority of the stopes are open to a depth in excess of 100 <br /> ' feet. <br /> MINING PLAN <br /> ' Mining started in 1911 and consisted of both underground and surface <br /> mining. The front veins along the entire length of the hogback on this <br /> property were mined from underground workings; many of the stopes are still <br /> ' open to the surface. One area that was surface mined (for silica sand) is <br /> within the stockpile area on Map Exhibit D-1 . When mining ceased in this <br /> ' area, a highwall (slope 1/2 to 1) was left that was approximately 200 feet <br /> long and 60 feet high. <br /> Mining will be conducted in 9 stages so as to minimize surface disturbances <br /> at anyone time. Area one (1) is located to the north of the stockpile area. <br /> The ov rburden from area one will form the base layers for the future waste <br /> from a ea 4B. Mining will proceed from Stage 1 in numeric order through <br /> ' Stage This staging pattern is shown on Map Exhibit D-1 . <br /> 1 <br /> ` , 8 <br />
