A goal in each half of the game by midfielder Habib Mohammed and striker Shafiu Mumuni gave coach C.K Akonnor's side an important win in their run to clinch the title this season.
It was the visitors who almost drew first blood by the 10th minute, after Sam Adams and Oba Ikama Ulitch combined to set up Elvis Opoku but his effort was blocked by Emmanuel Nti Mensah.
Three minutes later, Bright Agyei met a teeing cross from Ikama but the striker couldn't guide his effort on target, with Boubacar Hainikoye firing wide on 17th minute.
By the 22nd minute, Ashanti Gold made the visitors pay for their missed chances, after midfielder Habib Mohammed met a pass from a teammate and slotted in the opener.
Eric Donkor's cross by the 48th minute was connected by James Akaminko but Aduana's Emmanuel Akuoko made a goal line clearance to keep the visitors still in the game.
Ashanti Gold added another goal by the 59th minute, after Roland Amouzou was brought down in the box. Mumuni stepped up and sent goalkeeper Gordon Yeboah to the wrong side.
By the 75th minute, substitute Joseph Gordon, who replaced Abdul Latif Anabila, played Habib through but the youngster couldn't put his effort past goalkeeper Yeboah.
The visitors brought on Yahaya Mohammed and Samuel Bioh for Emmanuel Boateng and Ulitch but they couldn't find a breach in the hosts' defence to at least pull one back.
Ashanti Gold have now moved to second on the log with 27 points, tied with Medeama at the top, but the Yellow and Mauve have superior goal difference.
Aduana remain 14th with 14 points and will play Ebusua Dwarfs on June 13 in matchday eight outstanding game at Nana Agyeman Badu Park in Dormaa Ahenkro.
