The South African Senior Men’s National Team will participate in the Cosafa Castle Cup from the quarter-final stage against Group B winners on 18 June.
The tournament runs from 11-25 June 2016 and all matches will be played at Sam Nujoma and Independence Stadium.
"After long deliberations with the other coaches regarding the Cosafa Cup, we came to the conclusion that we must use this tournament to build our future teams," said Mashaba.
"Many a time we as national team coaches always talk about how little time we have with the players ahead of a big game and how we didn’t have enough time to prepare but now we have ample time to do that.
""The 2016 squad for the Cosafa Cup is mainly made up of u23 players and we are using the tournament as part of the preparations for the upcoming 2016 Rio Olympics," added Mashaba.
