Sandra Brown, Brock Bowles, and Stephanie Reigh from the DRMS <br />Denver office were also present. No operator /representative from Munger Canyon Mine was present during the <br />inspection; however, we did speak with April Schultz HR/Administrative Assistant at the McClane Canyon Mine <br />office prior to the inspection.
