Previous mining in the <br />region experienced local areas that were difficult to support because of weaker clay -rich strata in <br />the immediate roof. Both the Allen and Apache Seams locally have a clay -rich carbonaceous <br />roof that if not held during the initial cut will likely be included in the mining interval. The <br />weaker clay -rich immediate roof strata range from 0 to approximately 2.5 feet thick. This <br />weaker material if included in the run -of -mine product would be removed during the preparation <br />process and transported to the waste storage site. <br />2.04.6 (3a) (iv and v) <br />The New Elk Mine surface facilities have already been built or are under refurbishing. <br />The old workings of the Allen Mine, which extracted the Allen Seam, underlie these facilities in <br />part. No further production mining is planned beneath these facilities except for minor <br />development to reach a fan shaft within the Apache Seam. A core hole was drilled adjacent to <br />this vent shaft and the data including core descriptions is submitted herein. <br />TR56 2.04 -11g Revised 1 /10 /11 <br />
