<br />• <br />~II ~I~~I~III~I~~ ~I~ <br />999 <br />Phoenix Mine - MLRB File No. 82-75 <br />ADDENDUM to EXHIBIT B: Mining Plan <br />The charactex• of the waste rock to be stored in the <br />underground stope:> is broken quartz and Idaho Springs gneiss <br />formation. The bulk of the waste rock will not be removed <br />from the mine, but will be left underground in pre-existing <br />stopes. The end waste product from the ore dressing facility <br />will be transported to the stopes using a front end loader. <br />Initially the ore dressing will be by mechanical separation, <br />later float cells are proposed to be added to the circuit. <br />These will involve the use of such reagents as pine oil and <br />xanthates (which are non-toxic). <br />The anticipated amount of waste rock will reach a <br />maximum of 10 tons per work day. <br />
