(Page 3) MINE ID k OR PROSPECTING ID ~` M-97-032 • INSPECTION DATE 1113/99 INSPECTOR'S INITIALS RCO The waste rock pile is low and in a stable configuration. Its sides are sloped at about 1.5:1, but the angular material does not exhibit any instability or erosion. Its perimeter is set back from the boundary (the runoff control berm) by about 15 to 20 feet. The extreme southern end of it is not filled up to the same elevation as the remainder of the dump. Its surface is vegetated with volunteer native shrubs. There is no topsoil here, and if it is not disturbed by dumping more rock, it may be optional at the time of reclamation as to whether it should be redisturbed (i.e., top soiled for revegetation). The top surface of the rest of the dump is barren, the majority of which is graded smooth, and the southern remainder of it exhibiting small piles from loader dumps. The reclamation plan calls for backfilling the shafts with waste rock, and contouring the rest onsite. The topsoil will be spread over it, and the perimeter runoff control berm will be removed by dozing it smooth. Electric power is supplied through a spur which enters the site from the adjacent utility company-owned overhead lines. The onsite station consists of three poles with a platform holding six transformers. The operator stated these were owned by the operator. Transformers are all non-PCB type. The station is surrounded by a steel chainlink fence. Electric lines throughout the site are buried, and all buried portions will presumably remain after reclamation. There is an adjacent open-sided shack made from steel framing and galvanized roofing. It measures about 10 x 12 feet, and has a 6-inch thick concrete floor. Another shack onsite near the east boundary formerly held drums of oil and/or other fluids. It has a dirt floor, exhibiting oil staining, but holds no vessels presently. The structure • measures about 8 x 12 feet, also made from steel framing and galvanized walls and roof. It might not be utilized in the future at all. The operator agreed that storing containers of fluids would require some sort of secondary containment. The compressor building is constructed from corrugated steel siding and roof. Its floor is concrete. The floor's overall thickness and reinforcement are unknown, but there are two heavier-duty slabs built into the floor, one of which supports a compressor. These are each about 6 x 12 feet. It will be presumed that these slabs are reinforced. There is a large steel compressor tank mounted outside the building. It measures about 3 feet in diameter x 15 feet long. The hoist building is similarly constructed of steel framing and siding with concrete floor. The floor thickness and reinforcement are unknown. There is a narrow concrete sump extending through the building and an obviously thicker concrete slab under the workings of the hoist. The hoist mechanism is not dilapidated, and may have some salvage value. The headframe over the shaft is steel and bolted together. It is in good condition. It is about 80 feet high, and anchored by bolts on the concrete footers. The footers are above or part of the 30 x 30 foot concrete pad. The concrete thickness and reinforcement are unknown. The shaft collar is concrete. It and the hoist workings are enclosed by a steel mesh fence and locked gate. The shaft is about 6 feet in diameter and is not cased. It will provide the only access to the underground workings (within this permitted area). Ore, waste rock and personnel will use the shaft and manlift/hoist. The operator stated that the shaft was about 700 feet deep, but that figure was an estimate. There are three ore bins attached to the north side of the headframe. These handle the waste • rock and ore brought out of the mine. These too are either bolted to the concrete pad or anchored to concrete footers. They measure about ten feet square by six feet deep, and are supported by legs 10 to 12 feet tall. They are in good condition, and might fetch some salvage value at the time of removal for reclamation.
