This can be seen on Map 7 <br />Geology. The upper D-Seam outcrop is above the creek level. <br />The elevation of the upper D-Seam in the northeast corner of <br />the mine plan area is about 6345. The elevation of Hubbard <br />Creek immediately east of the northeast corner of the mine <br />plan area is about 6240. Therefore, th¢ upper D-Seam is about <br />200 feet vertically above Hubbard Creek at the seams lowest <br />point. <br />with regard to Jce Dudash's memo of July 12th I have the <br />following comments. <br />~I. The DMG notes that the completion diagrams for DH-54 and DH-55 <br />state that a portion of the casing is slotted. However, the <br />stippling in the drawing shows that the entire casing is <br />slotted. Only a portion Of the casings are slotted. The <br />stippling is shown incorrectly. <br />The DKG questions how monitoring well DH-55 can monitor the <br />entire lower perched water bearing zone, without including any <br />other zone. BRL has determined that well DH-55 does monitor <br />the lower perched water bearing zone. This ie based on <br />correlation with drill holes which defined the lower perched <br />water bearing zone. The DMG's question brings up a more <br />global question as to y(yy BRL is monitoring the perched water <br />
