<br />(Page 2) <br />MINE ID # OR PROSPECTING ID #: M-1977-365 <br />INSPECTION DATE: April 19. 2001 <br />OBSERVATIONS <br /> <br />INSPECTOR'S INITIALS: AIW <br />This was a normal monitoring inspection conducted by Tony Waldron of DMG along with Robert Vance of Park County Road <br />and Bridge. The site is located approximately 15 miles east of Hansel, Colorado. The pit is situated in an open range pasture <br />typical to the majority of South Park. <br />This site is no longer active and has been reclaimed, however, they are having trouble with vegetative establishment. It <br />appears that the site was mined in two locations that are separated by a small relatively undisturbed parcel. The north parcel <br />has been nicely re-graded and the revegetation efforts on this area seem to moderately successful at this time. Probably one of <br />the biggest problems is unlimited grazing activity which is not allowing the grasses that have established to seed and thicken <br />up the stand. On the other hand, the south parcel is not exhibiting much success with vegetative establishment and also has <br />one small slope that needs to be cut back to a 3H:1 V or flatter grade. It does not appear that any topsoil was replaced on this <br />area and the surface growth medium is rather coarse with little to no organic matter. As a result, the available water holding <br />capacity on this area seems to be very limited and even if grass seedlings were to germinate and establish, they probably <br />would not be able to sustain growth over time. <br />A couple of suggestions that might help would be to conduct a standard soil fertility test to determine if the soil has an obvious <br />problem such as high or low pH or a salt problem. Once that is done the operator will probably need to apply one of the <br />following amendments; bring in topsoil to a depth of 4-6 inches over this area prior to re-seeding or; mix in 20-40 tons of <br />manure into the existing surface material to increase the organic matter and fertility levels or; possibly try to amend the surface <br />material by incorporating PAM and a granular fertilizer. The PAM is a poly-acrylamide substance that absorbs water when it is <br />available and releases it to the plant as the soil dries out. In any event, the aforementioned slope will need to be graded out <br />and some amendment to the growth medium will probably be necessary in order to establish vegetation on this area. <br />No other observations were noted and this concluded the inspection. <br />I & E Contact Address <br />NAME: Robert Vance <br />OPERATOR: Park County Road and Bridge <br />STREET: P.O.
