.white marble bed have been considered to be waste material over the past number <br />. of years of operation. These materials are now considered to be ore and can be <br />mined for a number of industrial uses including cement rock raw material and <br />joint compound products due to its high calcium carbonate content. An estimate <br />for overburden material covering the ore body north of the current mining area <br />ranges from three feet of soil to bedrock (ore) exposed at the surface. A short <br />term estimate for waste rock produced for the next several years is a stripping <br />ratio of 1: i, based on the poor condition of mine development due to past high <br />grading operations more than long term mine plan projections. <br />29. The .25 acre of disturbed ground located within the Shamrock Claim, a patented <br />mining claim owned by US Lime, Dallas, TX, lies east of Taylor Gulch. The <br />mine operator's former contractor illegally cut this access road, which includes <br />two crossings of Taylor Gulch (FS Road 228 and another cut directly north of <br />228) which is the cause un-controlled sediment entering Taylor Gulch. It is <br />Colorado Marble's intent to keep mining operations isolated west of Taylor Gulch <br />and keep Taylor Gulch drainage separate from mine site drainage. This is neazly <br />impossible without the changes to mine plan described in comment paragraph 20 <br />above. The disturbed land will be reclaimed to its original condition including <br />fill, compaction, topsoil application, and seeding during 2006 if possible. US <br />Lime has been contacted by letter requesting their approval of this action and <br />requesting a formal statement to that affect Their response will be forwarded to <br />the Division as soon as it is available. The work plan submitted to the Division <br />July 6, 2006, included this work as part of the environmental correction work <br />scheduled as soon as road permits are approved by the FS_ <br />30. To the best of our knowledge, the Mineral Survey numbers reflect the more senior <br />patented right, lower number more senior than higher. Thus the Shamrock Claim <br />would have senior claimant rights over those portions of Colorado Marble's <br />claims. <br />31. The vertical shaft is a app. 8'x8' excavation mined in the central portion of the <br />white mazble seam. It can be viewed on the third active operating level of the <br />present disturbance. The excavation was mined in solid rock and no timbers or <br />cribbing was used in its construction in at least this portion of the shaft Mining <br />operations over the past twenty years have long ago removed any head frame <br />and/or structures that may have existed at the original surface contact of the shaft. <br />The shaft is of unknown depth, although reported by past mine owners to have <br />been 200' deep. The current condition of the shaft is filled tightly with white <br />mazble rock, which fills the entire shaft excavation. Mining has progressed <br />downward over time, with extra care taken for operating equipment in the vicinity <br />of the shaft. Due to the competent rock surrounding the shaft excavation and the <br />fact that the void is filled with mined rock, the struct~ae appears to present a low <br />degree of risk regarding working in the vicinity. Active mining will continue to <br />lower the shaft excavation surface exposure at the same elevation as the working <br />
