Police have found 60 kilograms of explosives buried at a farm property north of Saskatoon.

The material, which police called "commercial and military grade," is believed stolen and had been in the ground for more than a decade, the RCMP said Thursday afternoon in a news release.

The land owner had recently been made aware of the material after the death of a family member, the RCMP said.

Over eight hours, police dug up and destroyed some of the explosives, which were found in a remote wooded area on an acreage.

The military demolition charges had been manufactured during the Second World War but were still functional.

Those items have been returned to the Canadian Forces, the RCMP said.

No charges have been laid, but the RCMP said they continue to investigate.
