By using the last five years of production at the Vagneur Gravel Pit in <br />conjunction with the remaining resource, it is forecasted that the gravel will be depleted in <br />about 20 to 25 years. It should be pointed out that forecasts are based on current and past <br />information. Inherent with any forecast is a degree of uncertainty. A 25 year life span is <br />a relatively short period of time for a sand and gravel operation such as exists in the <br />Woody Creek area. <br />CRUSHING AND STOCKPILE AREAS -The excavated gravel resource is crushed and <br />stockpiled according to size on the pit floor. Maximum processing is approximately 3,000 <br />tons per day. Since a portable crusher is used, the location of the crushing operation and <br />processed stockpiles change as the mining proceeds across the mining area. Crushing <br />operations do not occur during the winter months, unless market demands require <br />additional material. Water is used constantly during the crushing operation to control dust. <br />The water source is from an existing permitted well located on the property_and is pumped <br />to an existing pond located near the asphalt production area. <br />ASPHALT PRODUCTION - A portable asphalt plant has been erected on the site. Material <br />crushed on site is used for asphalt production. Maximum production for the portable plant <br />is 2000 tons per day. In 1998 the plant which has operated on the site during the prior <br />years was replaced with a new "state of the art" plant. This new plant utilizes a "bag <br />house" to capture any fine particles of material from entering the atmosphere. The plant <br />meets or exceeds all State and Federal pollution requirements, and is inspected on a <br />regular basis by corporate and governmental authorities. <br />
