Police said on Friday that it is unlikely that the jumper, whose nationality was not publicly identified, would have survived his accident.
"The man is presumed dead but that is not confirmed since personnel has not reached him yet," Alf Stormo from the Møre and Romsdal police told NTB.
Police said previously on Friday that rescue crews were unable to reach the man.
“It is difficult to put [rescue] people in there. There are vertical steep walls, and the mission is dangerous,” Western Police operations leader Torry Aakenes told NTB, calling it "a difficult situation".
Police in Møre and Romsdal were notified of the situation at 7.30pm on Thursday. Within two hours of the call, they had located the jumper at a height of some 1,300 metre.
On Friday, rescue groups plan to draw up a plan for how to possibly extract the jumper.
Police know the identity of the man, but did not want to release the information until next of kin have been notified.
