• <br />Timing: The applicant anticipates that mining will commence in the spring of 1998. The <br />estimated size of the gravel deposit on this site is 8,000,000 tons. It will take <br />approximately 25 years to mine and reclaim this property. Annual production is estimated <br />to be between 320,000 and 500,000 tons. This may vary depending upon the demand for <br />construction material and may impact the total life of the mining operation. The property <br />will be mined in 8 phases, each phase will take between 2 and 3 years to complete (see <br />Mining Plan Map). Reclamation will proceed in conjunction with the mining of each <br />phase and will consist of regrading, replacement of topsoil, planting of trees and shrubs <br />and revegetation of pond banks. <br />Nature, depth and thickness of the deposit to be mined and the thickness and type of <br />overburden to be removed: Terracon Consultanu Western, Inc. (Terracon) performed a <br />geotechnical engineering exploration of this site and prepared a report on <br />October 14, 1997. Please refer to Exhibit I -Soils Information for a copy of the <br />Geotechnical Report. The nature, depth and thickness of the deposit to be mined and the <br />thickness and type of overburden to be removed is described in detail on page 4. <br />The primary commodity to be minedlextracted is sand and gravel. The intended use is for <br />construction materials. Secondary commodities to be mined include screening and sale of <br />topsoil not needed for reclamation of the site. Anticipated incidental production will <br />include gold that is recovered as part of the standard washing and screening operation. <br />Ha!!-Irwin Mining Proposal jor the Shores - MLRB l 12 Permit 14 <br />
