The sides went in level at 0-6 to 0-6 at the break before Conor Garvey's goal two minutes into the second half put Mayobridge three points clear.
Dromore fought back and O'Neill netted midway through the half to steer his team to a deserved two-point success.
The reward for Dromore is a semi-final clash with Crossmaglen next Sunday.
Dromore were the better side in the second half, their superior fitness and organisation proving decisive.
Mayobridge managed just one point after the interval with Michael Walsh supplying it five minutes from time.
Sean O'Neill starred for the victors, scoring six of their nine points and all from play.
