Mwansa also featured in the Saba Saba tournament in Tanzania in July 1967 though he did not see much action after this as Happy Malama was the preferred goalkeeper by national team coaches, relegating Mwansa to a reserve role. He made a return when Zambia met Cameroon for a place at CAN 1970 with Zambia drawing 2-2 at home in June 1969 and going out after a 2-1 defeat in Yaoundé on 3 August 1969 in a match where Zambia scored first through Godfrey Chitalu and conceded an equalizer by Confiance Moukoko in the 56th minute. Cameroun’s winning goal was conceded when Mwansa, in retrieving a ball which was going out for a goal kick collided with a Cameroonian attacker and a penalty was awarded in the 75th minute which sent Zambia packing.
