Mosaic says Esterhazy inflow rate cut in half

Plymouth, Minn.-The Mosaic Co. reported Feb. 16 that data collected from hydrogeologic testing performed this week indicates that the salt saturated brine inflow at its Esterhazy, Sask., mines has declined to an estimated rate of approximately 12,000 gallons per minute. This compares to the estimated initial inflow rate of approximately 20,000 to 25,000 gallons per minute. Inflow rate measurements reflect an estimate as of a particular point in time, and depending on when tests are conducted, rates can fluctuate up or down. Mosaic says the new measurement suggests that efforts to inject calcium chloride near the identified inflow area are beginning to impact the inflow as anticipated.
