Chippa initially signed Pentjie in February on a three-and-a-half year deal from Bidvest Wits.
However, the player only made four league starts for the Chilli Boys and does not feature in coach Dan Malesela's plans for next season, according to a source.
"Pentjie is one of the players leaving the club," says the source.
"The rest of of the list of players leaving the club will be released by next week."
Meanwhile, the Port Elizabeth-based club is prepared to field offers for midfielder Thamsanqa Sangweni.
