The Miners were going into the second leg having played 0-0 at home last week in the first leg in Ghana.
Salitas welcomed the Ghanaian club into the 60,000-capacity Stade du 4 Août 1983 on Saturday afternoon for a decisive confederation cup return leg
The host started on the front foot and got an early goal in the 14th minute through Olivier Boissy.
Boissy scored again just before the break to put the score at 2-0.
David Abagna responded quickly by pulling one back in the 45+3 minute to out the score at 2-1 before the break.
The second half started with the visitors pushing extra mile to get the goal that could take them into the next stage of the competition but their effort was not enough as the game ended 2-1.
The results mean Ashgold are out of 2020/21 Caf confederation cup competition.
