Cpl. Rob King says the remains that were found Saturday afternoon north of Herschel, Sask., were decomposed and that investigators won't know the identity until after an autopsy on Monday.
But RCMP say they have notified the family of Carol King, who is originally from Newfoundland, about the discovery.
The 40-year-old woman disappeared near Herschel, which is 150 kilometres southwest of Saskatoon, on August 6th.
Her car was found in a slough and a friend says she was on her way to Rosetown, Sask., to file a report with police about being harassed.
Officials say the remains were found by a volunteer about six kilometres from where King's car was located.
Mounties are calling her disappearance suspicious, but they have not revealed what led them to draw that conclusion.
King moved to the Prairies from the East Coast three years ago.
Last weekend, police used cadaver-sniffing dogs in their search around King's home and the slough, but they said they didn't find anything.
RCMP investigators are now at the site where the remains were located.
Police say the volunteer had heard about requests from RCMP asking people to check rural properties for signs of King.
The volunteer was from Saskatoon, police say, but is familiar with Herschel area and the property.
Police say at this point, they don't know whether the remains are those of a man or a woman.
King's father in Mattis Point, N.L., said earlier this month that he was losing hope that his daughter would be found alive.
