Leroy Lita netted an 83rd-minute winner for Boro to add to efforts from Scott Mcdonald and Tony McMahon double as the Lions slipped to defeat despite goals from Neil Harris and Hameur Bouazza.
And Mowbray singled out Zemmama, who assisted two of the Teessiders` goals, for particular praise.
Mowbray said: "He was a bit of class. He's a Moroccan international and I signed him for Hibernian five years ago.
"He's matured into a man but he was a boy then, although he's always had fantastic technical ability.
"For (Scott) McDonald's goal, having that extra bit of quality to thread the pass through was what was required."
