other major projects may accelerate mining production for short periods of time.The average <br /> production rate is estimated to be five hundred tons per day with total reserves in excess of three <br /> million tons.Therefore,the pit life is anticipated to be approximately fifteen years. With Phases 5, <br /> 6,and 7,the feasibility of mining these areas has yet to be determined As the Mining Phases are <br /> completed,a determination will be made. <br /> V1. NATURE OF THE GRAVEL DEPOSIT-The gravel deposit is located in an alluvial plain south <br /> of Florence.The gravel is layered in thickness up to twenty feet.Overburden on the proposed site <br /> varies in thickness from zero to greater than six feet.Generally,the overburden is a silty loam with <br /> very little distinction between topsails and underlying material.Organic matter is virtually non- <br /> existent in this soil.The strata underlying the deposit are a silt-clay shale formation. <br /> • <br /> • <br />
