Press Release

MOSAIC TO APPEAL PRELIMINARY INJUNCTION ON MINE EXTENSION;

MOSAIC TO HOLD CONFERENCE CALL

PLYMOUTH, MN, July 31, 2010 – The Mosaic Company (NYSE: MOS) today announced it will appeal a preliminary injunction entered Friday evening by the U.S. District Court for the Middle District of Florida which prevents impacts to federal wetlands on the Hardee County extension of Mosaic’s South Fort Meade phosphate mine in Central Florida. The District Court also remanded certain aspects of the permit back to the Army Corps of Engineers for additional information.

This ruling may impact Mosaic’s workforce, including the layoff of up to 221 employees, as previously announced, after the expiration of the 60-day notice period provided under the federal Worker Adjustment Retraining Notification (WARN) Act.

The preliminary injunction resulted from litigation brought against the Army Corps by several non-governmental organizations. The District Court’s ruling followed a July 22, 2010 hearing on the matter in Jacksonville.

“We’re disappointed by the ruling and will immediately seek an expedited appeal of the matter. We do not believe the decision was supported by the overwhelming facts supporting the Army Corps’ decision to issue the South Fort Meade permit. This permit has received a higher level of scrutiny and contains more environmental protections than any prior Florida phosphate mining permit,” said Richard Mack, Mosaic’s Executive Vice President and General Counsel.

Mosaic intends to conduct a conference call on Monday, August 2, 2010 at a time that will be determined and announced.
