3) The Mineral Joe Claims are a dry mine operation with little or no interception of <br />groundwater. There are no CDPHE required as there are no discharges or drainage <br />associated with this mine. <br />4) The JD-6 uses the Duggan Adit of the Mineral Joe for access and the Mineral Joe #2 Adit <br />as an emergency exit. No new mine openings are currently planned. Ore from the JD-6 <br />is being brought out to the Load Out structure at the Mineral Joe. The ore is stockpiled at <br />the Load Out Area on waste rock materials. Sloping of the Area is slightly toward the <br />structure so stormwater tends to drain away from the drainage and percolate through the <br />ground. Staff observed a loader and truck preparing a shipment of ore. Approximately <br />50 tons of material was observed stockpiled. The stockpile of ore is allowed to sit on site <br />for a minimal amount of time. The largest factor is maximizing the trucks and loader for <br />haulage. Ore sorting is done underground to maximize space availability at the surface <br />for support activities and shipping. <br />5) As with the JD-6, maps are from 1977 and with the exception of a 2001 site layout map. <br />Some areas of the Mineral Joe have been reclaimed and maps should clearly show those <br />areas as well as currently active zones, proposed future impacts and final reclamation <br />configurations. <br />6) Reclamation standards include the use of BLM /DOE seed mixes, removal of mine <br />debris and re-sloping: The adits will be used to bury debris and. buildings and sealed with <br />an earthen plug. Some topsoil exists and has been stockpiled for future use, although it is <br />limited. <br />JD-8 Mine. M-1984-014 <br />The JD-8 MINE is the newer of the permits under review. Current work is more developmental <br />at this site rather than production. The mine entrance is located on a narrow bench, which is <br />creating somewhat of a bottleneck for workspace. .. <br />1) This mine site is one of two that is actively bringing waste rock to the surface. As noted, <br />the site has limited workspace. Waste rock is being used to expand the work pad and <br />later will be placed in proposed dump areas. Waste has been dumped over older piles to <br />expand.the surface area~out to the north and east. Cotter has marked the outer limit of <br />the pad area and will cut a bar ditch to direct stormwater towards an existing drainage cui <br />off by the waste rock piles. Silt fencing will be used at the entrance points to control <br />sedimentation and off site disturbance. <br />2) No geochemical analysis has been preformed on waste rock materials. Cotter has <br />agreed to submit a composite sample of the waste rock once all issues are clearly <br />defined and agreed upon. <br />3) Currently, the JD-8 is a dry mine. However, given its closer proximity to the JD-9, it is <br />possible a discharge permit from CDPHE permit will be required in the future. No seeps <br />or springs are noted in the area. <br />4) A temporary office /mine dry trailer has been moved on site. Cotter plans to build a <br />permanent building some time in the future after the pad has been developed. The <br />building will include a concrete pad but the type of building is unknown as of this date. <br />The Division will include removal of the structure in the reclamation bond only after it has <br />been built. <br />
