Denbigh played some superb stuff in the opening half but failed to take the majority of chances that came with the only goal coming on 37 minutes through Kyle Scarisbrick.
2nd half and the game became stretched as both sides cancelled each other out.
On 75 minutes Mold Alexandra equalised through Andreas Economides.
On 84 minutes Denbigh Town had a massive let off when Mold where awarded a penalty from which Lee Jones missed by hitting the post.
Both sides continued to attack and on 88 minutes Alan Bull scored the winning goal to claim a first win in 6 as Denbigh Town progress to Round 2.
Mold will feel hard done to after improving in the 2nd half.
