Please provide revised maps and cross <br />sections to reflect post-mining topographies that more closely resemble the pre-mining <br />contours of the proposed disturbed area... <br />Trapper Response: The post-mining configuration for the Horse Gulch Fill has been <br />modified to eliminate the saddle that was shown previously. The fill now ties in to the <br />adjacent topography with no saddle. A more complete description of the mining method <br />used in K Pit is included as a part of Section 3.1.4.1, Mining Sequence, pages 3-15a and <br />3-15b. A discussion of safety requirements and resource recovery is included. Permit <br />P.O. Box 187 Craig, Colorado 81626 (970) 824-4401
