The Aussie open-wheel star has been in the frame for a Supercars endurance drive with PremiAir Racing since testing with the team earlier this year.
However he has faced an uphill battle to seal the deal, which would mark his Bathurst 1000 debut, thanks to the strict superlicence requirements put in place by Supercars.
While Motorsport Australia, the governing body and licence issuer, has given Mawson a licence, Supercars initially dug its heels in over its own additional requirements.
Those requirements are to have either made six starts in Super2 or hold gold status in the FIA driver rankings.
Mawson has never raced in the second tier of Supercars, his background mostly in open-wheelers.
He is a German F4 winner and has won the last two Gold Star titles in S5000 since returning to Australia.
Despite that success, he is still categorised as a silver driver by the FIA which means Supercars needs to sign off on his superlicence.
The matter has now been discussed at Supercars Commission level, with indications that the matter will be settled either through the FIA or via a dispensation.
That will leave him free to potentially sign with PremiAir and make his Supercars debut at the Sandown 500 in September, ahead of a Great Race debut the following month, both alongside Tim Slade.
PremiAir has already locked in Dylan O'Keeffe to partner James Golding in its #31 entry.
The enduro seat in the Slade Camaro is one of just two not yet confirmed, the other being the Blanchard Racing Team seat alongside Todd Hazelwood.
