Under the manorial administration imposed after the mediaeval English conquest of Wales, Minera existed as a manor and township within the Lordship of Bromfield.

[6] Extraction of lead and coal was later joined by the quarrying of silica stone and limestone, with three lime kilns being recorded in operation at Minera Mill in 1620.

The lead mines expanded under the guidance of engineer John Taylor and the Minera Limeworks came into operation, while a branch of the North Wales Mineral Railway was built in 1844 to serve the area.

Despite the loss of its traditional industries the village of Minera expanded rapidly in the period after World War II, thanks to the construction of council housing estates.

Minera St Marys only lasted one season in this competition, taking on the fixtures of Cerney Swifts and finishing second from bottom.
