The Mosaic Co. on June 4 announced that it is immediately closing the K1 and K2 potash mine shafts at Esterhazy. Closing K1 and K2 are key pieces of the transition to K3 but the timeline for the closure has been accelerated by nine months due to a recent acceleration of brine inflows.
The company said it is planning to resume production at the Colonsay potash mine and recalling workers as soon as practical. It said the restart will offset a portion of the production lost by the early closure of the K1 and K2 shafts at Esterhazy, and position the company to take advantage of the expected strong potash markets in 2022 and beyond.
