The Zimbabwe international spent the last three seasons on loan at KwaZulu-Natal side Lamontville Golden Arrows from Sundowns.
Late last year, it was reported that Pirates had reached an agreement with Sundowns which would see Mahachi join the Soweto giants at the end of the 2017/18 campaign.
The left-footed player was then quoted in January 2018 confirming that he will be joining the Buccaneers at the end of the season.
However, the Buccaneers remained mum regarding Mahachi’s proposed transfer to the Houghton-based outfit.
Pirates administrative officer Floyd Mbele has since revealed that they have held talks over Mahachi‘s services at the start of the recent campaign.
“There were discussions at the start of last season over Mahachi‚” Mbele told TimesLive.
However, the Bucs club official insisted that there was nothing to report on regarding their pursuit of the talented attacker.
“But it would be premature at this point to say that he is our player. For now there is nothing to report on this,” he concluded.
Mahachi made 22 appearances in the Premier Soccer League (PSL) for Arrows during the 2017/18 campaign - netting four times in the process.
The Buccaneers are expected to beef up their squad this winter having qualified for next season's Caf Champions League.
The club is also looking to re-sign South Africa international Andile Jali, who is currently a free agent having parted ways with Belgian First Division A side KV Oostende last month.
However, Pirates are facing stiff competition from PSL rivals Kaizer Chiefs and Sundowns, who are also keen to snap up the highly-rated central midfielder.
The next PSL transfer window is expected to open on the 1st of July, 2018.
