Mahlambi has been called up to the Amajita squad by coach Thabo Senong for the Under-20 Africa Cup of Nations, which will take place in Zambia from February 26 to March 12.
However, The Clever Boys are insisting on retaining their star player as they build up to the climax of the Absa Premiership season, while also looking to compete in the CAF Champions League this year.
The 19-year-old forward previously represented the national U-23 team at the 2015 U-23 Africa Cup of Nations in Senegal, where he played a key part in helping coach Owen da Gama's side qualify for the 2016 Rio Olympic Games.
This time around, though, Wits CEO Jose Ferreira is unwilling to budge on Mahlambi's release, with SAFA going as far as threatening sanctions should the player fail to report for duty.
Hunt has since chimed in, saying that Mahlambi is an integral part of his squad, particularly after his contribution in their 5-0 thrashing of Baroka on Wednesday evening proved that.
"Yeah, he's an important member of our squad and he plays a big part in our team, so yeah," Hunt told reporters after the match at Bidvest Stadium.
The School of Excellence graduate now has four goals and four assists in five appeareances since returning from a near-10-month lay-off due to a cruciate ligament rupture he suffered exactly a year ago.
