An away draw for Primeiro Agosto ensured the army club's first GiraBola title in seven years after they moved into an unassailable position in Angola's championship.
Jan Brouwer has led Primeiro Agosto to their first title since 1999
Sunday's 0-0 draw with Bravos do Marquis in Huambo gave the leaders the point they needed to ensure a first championship success since 1999.
Coached by Dutchman Jan Brouwer, Primeiro Agosto moved to 50 points, out of the reach of second-placed Inter Clube on 37 points with four rounds of the championship left to play.
The top two finishers in the GiraBola qualify to play in next year's African Champions League.
