On February 21, 2008 Memphis Stone & Gravel Company participated at the Mississippi Acedamy of Sciences annual meeting in Olive Branch, MS.  Below is an abstract of the presentation. 

CHARACTERISTICS OF THE AGGREGATE INDUSTRY AND MEMPHIS STONE AND GRAVEL COMPANY’S MODERN MINING CYCLE, presented by Alan G. Parks* and William D. Kelley, III*, Memphis Stone and Gravel Company, P.O. Box 1683, Memphis, TN, 38106

Memphis Stone and Gravel Company mines “pre-loess” sand and gravel terrace deposits, often referred to as the Upland Complex, to produce high quality construction aggregate for the construction markets in the Memphis Metropolitan Area and Northwest Mississippi. Aggregate is broadly divided into three categories: sand, gravel, and crushed stone. These products are the basic raw materials used in the manufacture of concrete. A five part “Mining Cycle” brings these natural resources from initial discovery to the market place and returns the land for other productive use. These five parts include: exploration, planning, mining, processing, and reclamation. Construction aggregate is a high weight, high volume commodity, which trades at a relatively low unit cost. Proximity to market and efficient management is critical due to the high transportation costs. According to US Geological Survey estimates, per capita consumption of aggregate exceeds ten tons per year. It is projected that we will require as much aggregate in the next twenty-five years as we have used the previous century. Memphis Stone and Gravel Company is well positioned to meet this demand, but aggregate availability will be challenged by competing land uses, regulatory approvals, and the geological characteristics in the area. Often aggregate mining is faced with community opposition with concerns about environmental impacts, effects on property values, and increased traffic. But given the opportunity Memphis Stone and Gravel Company can demonstrate that the modern mining cycle does not require a community to accept aggregate development at the expense environmental protection and quality of life.
