Grady Aggregate is a high calcium facies of the Suwannee Limestone, typically averaging in excess of 98% calcium and magnesium carbonate with minute mineral contaminates. Drilling programs conducted indicate a reserve base of 14.8 million cubic yards (27.6 million tons) of total limestone existing from 40 feet below the water table to top of the rock. Approximately 9.8 million cubic yards (19.6 million tons) are above the water table and are recoverable under the condition of the mining permit issued by the State of Georgia. The permit can be modified to accommodate under water mining as confirmed by the Surface Mining Division of EPA in Atlanta. The total limestone volume (30,000,000 million tons) lies beneath an average of 26 feet of overburden on 70 acres. Grady Aggregate will mine from the Suwannee Formation at its operation in Grady County, Georgia. The stone is a tan-white to white fine grain fossil ferrous high calcium limestone with varying degrees of induration (hardness). Typically, the stone becomes whiter and softer at depth. Core drilling has indicated this relationship to be present throughout the ore body. Because of the varying degrees of relative hardness and color, stone from this quarry will support a wide spectrum of varying markets.
