PERMIT #: M-2011-009 <br />INSPECTOR'S INITIALS: MAC <br />INSPECTION DATE: June 29, 2015 <br />OBSERVATIONS <br />The inspection was conducted by Michael Cunningham of the Division of Reclamation, Mining and Safety <br />(Division). Mike London was present on behalf of IGWT Mining, Inc. The Hector Placer Mine is located <br />approximately 1 mile south of Alma, Colorado in Park County. The site is permitted for 100 acres and the post - <br />mining land use is wildlife habitat. The primary commodity mined is gold. <br />The purpose of this inspection was to follow up on a corrective action issued during the previous inspection <br />conducted on May 28, 2015. During the May 2015 inspection, the Division observed water seeping from the <br />south end of the lower settling pond. The lower settling pond receives process water from the sluice plant; <br />water from the lower settling pond is pumped back to the sluice. The process water was seeping through the <br />side wall of the settling pond and was also found to be percolating from the ground surface. The Division cited <br />a problem and required the Operator to reconstruct the earthen embankment, such that it was of a sufficient <br />height and compaction to eliminate any seepage from the settling pond. <br />The Operator performed a substantial amount of earth work at the south end of the lower settling pond. The <br />embankment was raised on the south end by several feet and compaction was achieved through multiple <br />passes of a wheeled front end loader. In addition, the Operator filled in the low lying area off of the southwest <br />corner of the settling pond where water was ponding. The Division traversed the south end of the settling <br />pond and did not observe any areas of seepage. The soils and colluvium around the perimeter of the settling <br />pond were dry and the Division is satisfied that the Operator has taken the necessary measures to prevent <br />seepage from the pond. The Division considers the problem to be resolved; however, the Operator should <br />perform periodic inspections of the pond perimeter to ensure that seepage does not occur in the future. <br />This concluded the inspection. <br />Page 2 of 4 <br />
