This partial inspection of the New Horizon Mine was conducted by DMG staff from the DMG Durango Office, 484 Turner Drive, Building F, Suite 101, Durango, CO 81301, phone (970) 247- 5469. Operations were active during the time of this inspection. Ross Gubka was present during the inspection. ACTIVE PIT AREA was observed from County Road BB. Reclamation backfiil, grading and topsoil replacement appeared current. Side roll irrigation equipment was intact and watering recently seeded and topsoiled areas. Recently reclaimed areas appeared stable, no evidence of slumping, settling or excessive erosion was observed. Affected area drainage appeared to be controlled in accordance with permit conditions. RECLAIMED AREAS NORTHWEST OF THE ACTIVE PIT AREA SAE 003 Sediment containment sump was dry, well vegetated and stable. Vegetative cover for reclaimed areas was well established and appeared sufficient to control erosion. Operator has controlled erosion and sedimentation in the sediment containment ditch by installing energy dissipating straw bales. Evidence of minor erosion within the sediment containment ditch appeared to have occurred prior to installation of the straw bales. Pond 004 Pond 004 was dry. Reclaimed areas within the watershed for Pond 004 were well vegetated and stable, no evidence of slumping or excessive erosion. Pond inslopes and embankment were well vegetated and stable. Primary spillway was clear of debris, no discharge noted, brush guard and anti-vortex fin were intact on the CMP inlet riser. Secondary spillway appeared stable, no evidence of discharge. Russian knapweed was established along the county road and has infiltrated across the permit boundary onto the pond embankment. The noxious weed was not well established within the permit area but will become a serious pest and possible obstruction to successful revegetation if not eradicated prior to establishment.
