Section 3.0 Gold and Gravel Mine Facilities <br />The gold and gravel mine operation will consist of the following facilities: <br />- portable gold processing plant <br />- truck scale with small portable scale office <br />- assorted power poles delivering power to the camp area <br />- 2 portable trailers for employee temporary housing 1 -8' x 40', 1 -14' x 70' on metal skids <br />- 1 office trailer on metal skids 14' x 38' <br />- 2 porto - potties for employees and visiting personnel <br />- equipment and material storage on skids or palettes for easy removal <br />- various portable plastic water lines delivering water from the pumps in the pit to the processing <br />site <br />- fixed gravel process plant (not in use) <br />- portable crusher, screen and stackers for gravel operation <br />- front end loaders of Cat 966 or 980 size (1 or 2) <br />- haul trucks of 25 -35 ton capacity, (2 or 3) <br />- Cat D -8 size dozer (1 or 2) <br />- Cat 245 or equivalent track hoe for gravel or placer material excavation <br />- in pit pump and 8" piping into process plant or settling ponds <br />- one 1200 gallon diesel tank with berm and liner for secondary containment <br />No blasting will take place in this operation. Any spills of fuel or other hazardous material will be <br />reported to the Division as soon as they are discovered. <br />Section 4.0 Highwalls <br />It is important that the placer operation be allowed to mine material near the bedrock since this <br />material will have the highest concentration of gold. It is also important that this excavation be <br />minimized to lessen the amount of water exposure and also lessen the amount of backfilling <br />needed for reclamation. For this reason, the water exposure for the placer excavation pit will be <br />limited to a maximum of 9000 square feet ( .21 acres). Since the depth to bedrock is <br />approximately 80 -120 feet from the surface in most areas within the permit, and since a track hoe <br />can reach approximately 25 feet down, highwalls of approximately 55 -95 feet may be needed. <br />Greg Lewicki, P.E. conducted an inspection of the current placer pit on October 12, 2012. The <br />highwalls were observed carefully. It was noticed that a significant amount of natural cementing <br />has occurred in the gravel, giving it high strength, even in steep walls, as shown in the following 2 <br />photographs. <br />
