Pantyffynnon Quarry currently comprises two active quarry sites which are located south of the A48, near Bonvilston.

The quarry is divided into two parts by Pant-y-Ffynnon Lane which also provides access to the site. Mineral extraction currently takes place to the south of the road and the mobile processing plant, offices and weighbridge are located in the northern area. A disused, fixed processing plant is also located within the northern area and is to be demolished in order to allow excavation of the stone resource beneath.

There are three main phases to the proposed development of the quarrying activity:

The deepening of the North Quarry through drill and blast. Simultaneously the removal of the existing ramp in the South Quarry void will also take place and the creation of a replacement ramp using waste materials which are already on site, supplemented by imported inert waste as required. In addition to proposed quarrying in the North Quarry, the remaining reserve in the South Quarry will also be removed through drill and blast for processing in the North Quarry.

Completion of the limestone extraction in the North Quarry and the infilling of the North Quarry void. Waste materials that are generated from the recycling operation to be placed in the South Quarry or eastern part of the North Quarry.

Restoration - Completion of the infilling of the North Quarry. The recycling operation will be moved from the South Quarry to the North Quarry.
