TORONTO, May 20 (Reuters) - An employee died Sunday at a

Nutrien ( NTR ) potash mine in Saskatchewan, temporarily

shuttering the operation as the company conducts an

investigation, the Canadian Broadcasting Corp reported Monday.

The company did not immediately respond to a request for

comment on the incident at the railcar-loading facility at its

mine near the town of Rocanville, about 250 km (150 miles) east

of the provincial capital Regina.

Potash is a primary ingredient in agricultural fertilizers.

According to the CBC, the company said it is conducting an

internal investigation and is cooperating with Saskatchewan's

Ministry of Labour Relations and Workplace Safety.

"Our current focus is on ensuring we have support services

available to all those involved," the CBC quoted a Nutrien ( NTR )

statement as saying.
