The Miners were beaten 1-0 in Tarkwa after Samuel Enzemaba recorded the only goal of the fixture on Sunday
The Mauves and Yellows are on top of the summit with 42 points after Matchday-22. Samuel Enzemaba got the only goal of the game from a well rehearsed free kick in the 19th minute to leave Bashir Hayford and his charges with nothing to smile about.
The results remained unchanged after the interval. The Brothers have recorded 12 wins, six draws and four loses in the 2012-13 season of the domestic top flight.
The Miners have dropped to the fifth spot after 22 games and have amassed 34 points.
Medeama will next play Amidaus Professionals whiles Ashgold face Berekum Arsenals on Wednesday.
