The Lions this season finished bottom of the Investec Super Rugby table and were stripped of their status, which will result in the Kings and the Eastern Province rugby region making their debut in the competition next year.
Despite winning the Currie Cup Premier Division last season, the Lions have had a difficult campaign in 2012, with the fallout already costing assistant coach Carlos Spencer his position.
Mitchell, despite being talked about as the new head coach of the Sale Sharks, was determined to fight for his future and remain in the Republic.
The Lions released a brief statement and said that Mitchell will rejoin the Lions on full duties next week.
The Golden Lions Rugby Union, which oversees the Lions, said they will make no further comment on the matter.
Mitchell and his lawyer Brian Patterson said that the coach had been cleared of all charges.
