The annual average tonnage mined and sold fiom the site are best predictions since many factors <br />such as the economy, competition, etc. geatly affect the actual sales. <br />~~ <br />The life of the gavel operation will be 15 years. Where the gavel is mined from is not easy to <br />determine since it is very dependent upon the gold operation. If the gold operation is viable over the <br />12-13 years shown in the plan, a large part (60,000 tpy) of the gavel sold from the site will be the <br />waste gravel from the gold plant. If the gold operation is uneconomic, gavel will then be <br />aggessively mined from the gravel mine azea as shown on Map C-2. For planning purposes, it is <br />predicted that the gravel operation will be in place 15 years at an average product sales rate of <br />130,000 tons per yeaz, with 2 possible scenarios: <br />1) The gold mine operates for 12 years and using the same average of 130,000 tons sold per yeaz, <br />60,000 tons per yeaz will come from the waste gravel from the gold plant for 12 years and all <br />tonnage coming from the gravel mine azea for the remaining 3 yeazs. Therefore, the tonnage to be <br />mined from the gavel azea is 70,000 tons per yeaz x 12 years + 130,000 tons x 2 years = 1,100,000 <br />tons. The reclamation plan map assumes that this case will occur, therefore, it shows a volume <br />removed in the gavel mine azea of 1,100,100 tons. <br />f, J <br />2) The gold mine does not operate for any significant period of time. In this case, the gravel mine <br />will produce al! sold material from the gravel mine azea, which is basically 2,000,000 tons over the <br />15 year period. Almost all of the previously mined azeas aze reclaimed from gravel mining. <br />In either scenario, front end loaders will be used to deliver the raw gavel to the crushing, screening <br />and wash plants for sepazation into various products. Fogger sprays will be present in all three <br />plants to keep dust down. The crusher will also employ sprays. The plants will be located to <br />minimize impacts to the town of Alma. <br />The breakdown of the disturbed acreage is given below: <br />i~ <br />Alma Placer 7/03 23 <br />
