The dressing floors, located northwest of the mineral railway track, included a battery of ore bins. Other on-site buildings included the Manager’s Office, main workshops, sawmill, blacksmith’s shop, joiner’s shop, fitter’s shop, and storage facilities. The smithy, which also functioned as a mortuary, lies in a deteriorated state south of Taylor’s Shaft at SJ 2702 5116.

Additionally, the foundations of the cottage at Pant-y-naf, once home to the worker responsible for the reservoirs, remain at a basal level alongside its enclosed garden.

The Minera Mines were developed within Carboniferous Limestone, with both the Main Vein and the Red Vein being exploited. The site was well-connected, with the 1850s mineral railway linking all major shafts to the smelting facilities at New Brighton. Today, the railway route remains visible as a public footpath.

Taylor’s Shaft was the central hub of mining activity for the Minera Mines from the mid-19th century. The site, located to the southwest of the mineral railway track, played a crucial role in lead extraction and processing. Various shafts, including Bryn Heulwen Shaft at SJ 2683 5125, were used for access and ventilation. The mining operations continued into the early 20th century, with the main pumping engine being sold in 1910 and smaller engines operating until 1908.
