Plymouth, Minn.-The Mosaic Co. on Nov. 12 responded to market rumors about elevated levels of brine inflow in the mined-out area at its Esterhazy, Sask., potash mine. The company said that brine inflow rates rise and fall regularly. The current rate of brine inflow is elevated, but within the historical range of inflows at Esterhazy. The company says it is evaluating the inflow and is managing it as in the past. Mosaic said it has successfully mitigated brine inflows at its Esterhazy mine since 1985. The Esterhazy mine has an annual production capacity of approximately 5.3 million mt. The last reported new inflow development at the mine was reported in 2007 (GM Jan. 29, 2007). Mosaic and PotashCorp are currently in litigation over how much longer PotashCorp will be entitled to a share of the potash from the mine (GM Aug. 17, 2009) – PotashCorp says until 2012, Mosaic says 2010.
