(Page 2) <br />M{NE ID # OR PROSPECTING ID #: M-1977306 <br />INSPECTION DATE: 3/24/05 <br />OBSERVATIONS <br />INSPECTOR'S INITIALS GRM <br />This inspection was conducted as part of the normal monitoring program established by the Colorado Division of <br />Minerals and Geology. The JD-6 and associated Mineral Joe Claims, JD-8, JD-9 and the Wright Group / SM-18 <br />Mines have begun mining operations after a lengthy period of minimal activity. The Division of Minerals and <br />Geology is inspecting the referenced sites in conjunction with permit reviews to ensure that permits meet current <br />standards for metal mining activities. No problems or issues will be noted within this report specifically as any <br />concerns will be addressed through the permit review process for each site individually. <br />The JD-9 Mine is the most complex of the mines noted above. The main entrance is in the Bull Canyon area of <br />Monogram Mesa. The JD-9 has a shaft at the top of the mesa that is an emergency escape way as well as the point <br />where water from the under ground working is pumped for treatment and de-sedimentation prior to release down the <br />canyon. For clarity, this report will break down the observations into the shaft area and Mine Entrance azea. <br />The Main Mine Entrance Area has a permanent building for equipmentmaintenanee and supply storage. Several ~ - -. <br />loaders and mine equipment were noted in use or pazked in this azea. The onsite fuel tanks are in proper secondary <br />containment constructed of earth berms and thick plastic. The area azound the building is free of debris'and well <br />maintained. (Photos 2 and 5) <br />Waste from current activities is being gobbed or backfilled into old workings to reduce haulage expenses and reduce <br />surface impacts. Established waste piles have been graded on the top but slopes are not impacted at this time. <br />The slopes are stable with only minor riling noted. Some mine debris was observed over the slope edge, which <br />should be cleaned up as much as possible. A 36" culvert• runs- through the waste pile where water from the <br />dewatering process passes. This culvert directs the water through the pile.while minimizing contact with the waste. <br />'The natural drainage then carries the water along the toe of the waste piles and then down gradient: (Photos 1,2 and <br />3) <br />` ~ - ;some ore has been brought to the surface for stockpiling. •°The operator stockpiles ore until there is enough far ' <br />several loads. ?,t which point, the stockpile is removed and the.process started over. Overall, ore stockpiles at any_• <br />sites remains for only short periods of time prior to shipping: Berrrisai'ound theatockpile area prevent; stormwater. ~ ~, <br />fortn;escaping into ;undesirablep1aces.

The sheds house the :~'.~;ii: <br />pump§~and water treatment tanks. The inspector watched as Mr. Williams added barium chloride to one of the ' ' <br />tanks. The water from the tank goes into a preliminary settling pond and then down to a secondary pond prior to <br />release. The primary pond is noted as beginning to be silted up. (Photos 10,11) The liner above the water line is ' <br />also beginning to show signs of deterioration along the free board of the pond. The secondarypond is in much better <br />shape. (Photos 6,7,8 and 9) It should be noted that the operator has already built new ponds just to the west of the <br />current ones. The only part missing is the installation of a liner prior to activation. This pond construction was part <br />of an amendment a few yeazs ago. (Photos 13,14) CDWQ has an active dischazge permit that requires submittal of <br />monthly samples to monitor water quality. <br />There were no observed fuel tanks or storage of petroleum products noted in this azea. This area is somewhat <br />isolated from general workers so housekeeping isn't great but not an issue of concern either. <br />
