A 35 year old father of two from the Yorkton area lost his life in an incident at Mosaic's K3 site last week. Mosaic says a "fall of ground incident" was the cause of the fatality.
A fall of ground incident is described as Fall of Ground (FOG) in mining refers to the dangerous, unplanned collapse or dislodgement of rock from the roof (hanging wall) or walls (ribs) of underground mine openings or open-pit slopes, a leading cause of fatalities and injuries due to geological stresses, weak rock, and mining activities. This can range from small rock fragments to massive collapses, often exacerbated by depth, seismic events, blasting, and inadequate support, creating significant hazards for workers and equipment.
“The Mosaic Company is deeply saddened to report that early this morning on Monday, December 15, 2025, a fall of ground incident occurred at the K3 underground mine in Esterhazy, Saskatchewan, resulting in a fatal injury to one employee. No further injuries have been reported,” says Mosaic in a statement.
“Mosaic's Emergency Response Team was activated following the incident. The site has now been secured and all mining activity has been temporarily halted. A full investigation is underway and Mosaic is working closely with all regulatory authorities. Support services are being provided through the company's Employee and Family Assistance Program.”
“The safety and wellbeing of our people remain Mosaic’s highest priority. Our thoughts go out to our colleague’s family and friends, all employees, and the broader community. We ask that the family be given privacy at this difficult time.”
