Hardee County Phosphate Rock Mine

        In 1975, we purchased 20,000 acres of land in Hardee County, Florida that was originally estimated to contain in excess of 100 million tons of recoverable rock reserves. Between 1978 and mid-1993, we operated a one million ton per year phosphate rock mine on a 5,000-acre portion of these reserves.

        In 1992, we initiated a project to expand and relocate mining operations to the remaining 15,000-acre area of the reserve property. The new phosphate rock mine cost $135 million and began operations in late 1995. In 1997, we added approximately 20 million tons to our reserve base through an exchange with a neighboring rock producer. In 1999, we acquired 1,400 acres containing an estimated 8 million tons of rock reserves. In 2008, we acquired approximately 800 acres of land containing an estimated 1.6 million tons of rock reserves.

        The table below shows the estimated reserves at the Hardee phosphate complex as of December 31, 2008. Also reflected in the table is the grade of the reserves, expressed as a percentage of bone phosphate of lime (BPL) and P2O5. Finally, the table also reflects the average values of the following material contaminants contained in the reserves: ferrous oxide (Fe2O3) plus aluminum oxide (Al2O3) and magnesium oxide (MgO).

        Our phosphate reserve estimates are based on geological data assembled and analyzed by our staff geologist as of December 31, 2008. Reserve estimates are updated periodically to reflect actual phosphate rock production, new drilling information and other geological or mining data. Estimates for 99% of the reserves are based on 20-acre density drilling.
