I didn't look at the whole game but . . . Not a stalemte.
70. Qc4+ Ka5 forced not other place to go.
71. Qb5# check mate.
Also around move 58 white could have contained the black king on the eight rank and there were various methods to mate black.
I was amuzed by the way.

Okay so I put double peices for both sides and then played both sides pretty equel and after 70 moves it became a stalemate.
