PERMIT #: M-1977-410 <br />INSPECTOR'S INITIALS: MAC <br />INSPECTION DATE: November 18, 2010 <br />OBSERVATIONS <br />The inspection was conducted by Michael Cunningham of the Colorado Division of Reclamation, Mining and Safety <br />(Division). Tom Hendricks of Calais Resources Colorado, Inc. and Bruce Humphries of Regulatory Permits Management, <br />Inc. were also present for the inspection. The Cross Gold Mine is located 5 miles west of Nederland, CO. The site is <br />permitted for 2 acres and the post-mining land use is residential. The weather was sunny and there was between 6" - 12" <br />of snow on the ground. <br />Availability Of Records: <br />The Operator indicated the Cross Gold Mine has been issued an APEN permit and has an FEL permit with the ATF. A <br />review of the permit file found the Division does not have copies of these permits. The Division requests the Operator <br />submit copies of these permits for the record. <br />Financial Warranty: <br />The Division currently holds a financial warranty in the amount of $15,400 which is sufficient to complete reclamation at <br />the site. <br />Gen. Compliance With Mine Plan: <br />Currently there is no mining taking place at the Cross Gold Mine. The mine site contains the following structures: <br />1) A mobile trailer which is utilized as an office space. <br />2) A storage warehouse which contains core samples and a compressor. <br />3) An equipment shop which was undergoing internal repairs at the time of the inspection. The shop contained drill <br />equipment, mine related PPE, a shower area, and barrels of lime used in the water treatment process. The adit can be <br />accessed through the equipment shop, a locking door controls access to the adit. There is also an external entrance to the <br />adit, which was controlled by a set of aluminum doors which have been sealed. <br />4) A cabin used as a residence and a caretakers quarters which is not currently being used. <br />The Division approved Technical Revision - 04 on July 21, 1999, which revised the Reclamation Plan to allow all <br />buildings to remain onsite after the completion of reclamation. The Operator has made repairs to the snow shed during the <br />past year. Wood timbers within the snow shed were replaced with Douglas Fir 6" x 6" and 8" x 8" posts. <br />Support Facilities On-site: <br />The water treatment system operates year round and was functioning properly during the inspection. The water treatment <br />system consists of two lined ponds, upper and lower. Water flows into the upper pond through a pipe which collects <br />gravity flow from the tunnel level of the mine workings; water enters the mine as snow melt/surface runoff. The upper <br />pond drains into the lower pond, which discharges into an elevated pipe and into Coon Track Creek. The average <br />discharge rate is 19 gpm. The water is treated with lime to control pH levels. The Operator was treating water as it <br />discharged from the lower pond; however, this method was not effective in controlling the pH level of the water. The <br />Operator now treats the water at the upper pond by adding powdered lime; this method has proven to be successful in <br />controlling pH levels. During the inspection, the Operator provided the Division with a copy of the 2010 3rd Quarter <br />Water Quality Report, which is submitted to the CDPHE as a requirement of the Operator's NPDES Permit. During the <br />past year, the Operator performed concrete and dike work on the lower pond dam. The improvements to the dam and the <br />freeboard of the two ponds was not inspected due to snow cover. <br />Signs and Markers: <br />The permit sign was posted at the entrance to the site as required by Rule 3.1.12. <br />This concluded the inspection. <br />Page 2 of 3
