Mabasa was on Tuesday officially unveiled alongside five other new signings including Denwin Farmer and Linda Mntambo ahead of the new season.
The 25-year-old striker has joined Babina Noko on a loan deal from Orlando Pirates for the 2022/3 campaign.
"It's an honour to be part of this growing club," Mabasa said.
"What the supporters can expect from me is definitely dedication and scoring goals as well and most importantly for me to enjoy my football.
"I am grateful to the chairman for the opportunity he has given me and the warm welcome I have received from the other players, the technical team and the coaches. I have enjoyed it so much.
"What the supporters can expect from us this season like we have been saying, turning our loses into draws, our draws to wins and achieve more wins going into the new season and finish as high as possible in the league," he added.
Sekhukhune United are set to relocate to Limpopo and use the Peter Mokaba Stadium as their new home ground for next season.
