Katlego Mohamme's own goal and Naby Bangoura's penalty ensured Guinea finished third at the 2017 U20 Africa Cup of Nations after beating South Africa 2-1 at the National Heroes Stadium on Sunday afternoon.
Amajita's only goal came through Liam Jordan in the first half as they bagged the fourth spot at the tournament in Zambia.
As early as the first minute, Amajita dictated the terms as Kobamelo Kodisang nearly opened the scoreline only to see his shot saved by goalkeeper Moussa Camara.
However, in the fifth minute the South Africans broke the deadlock through Jordan who showed great composure in the box when he was set up from the midfield.
Despite their lead, Thabo Senong's men conceded a silly own goal two minutes later when Mohamme tried to header back his keeper, Sanele Tshabalala, who did not anticipate the pass and it easily beat him handing Guinea a goal, 1-1.
The Junior Syli Nationale combined well in the middle fo the park in Amajita's half, but Morlaye Sylla failed to hit the target from a well drilled shot in the 29th minute.
In the 38th minute, Itumeleng Shopane was set up by Grant Margeman, but the Kaizer Chiefs striker was denied by Camara from close range.
It was 1-1 at the break.
With less than 30 minutes to go, Tshabalala produced a fine save to deny the Guinean forward in the 63rd minute from a distance.
Alseny Soumah came close to bagging the lead in the 69th minute when he found himself unmarked in the box, but his effort went wide of the target.
With seven minutes to go, Tercious Malepe committed a foul in the box and striker Bangoura converted from the penalty spot to make it 2-1 to Guinea.
Amajita wasted a beautiful chance when Thendo Mukumela's free header sailed over the cross bar in the injury time as the South Africans finish at number four.
