The main surface workings of the mine were concentrated in the central area, which was once home to numerous industrial buildings. Transporting ore and materials was facilitated by horse-drawn iron tram wagons operating on a surface railway. A siding from the Prestatyn-Dyserth Railway, constructed in 1869, connected directly to the mine, ensuring a steady supply of coal and the efficient movement of ore.

Several steam engines powered the mine’s operations, with an 80-inch pumping engine working at the Engine Shaft, supported by six ‘egg-end’ boilers. A 22-inch horizontal engine powered the capstan and winding gear. By 1874, the site had fifteen steam engines of various sizes, including 100-inch, 36-inch, 24-inch, and 18-inch engines, in addition to five donkey engines. These were supplied by nineteen boilers, with coal transported via the Prestatyn-Dyserth Railway. In addition to steam power, the mine relied on water power, with leats constructed in the 1750s and again in 1844 to drive 20ft and 40ft waterwheels. The best-preserved section of the 1750s leat remains visible in woodland below Graig Bach at SJ 0605 7980, where stone walls define a two-meter-wide channel.

The ore extracted from Talargoch was processed at the dressing floors located at Coetia Llys and Maesyrerwddu. Some remnants of the mine’s industrial past can still be seen today. To the west of the former mine office, below the track of the mineral railway, a substantial stone wall, possibly the remains of an engine house, has been incorporated into a private garage. At SJ80600597, near a small caravan site, another stone structure, which has been incorporated into an enclosure wall, may have once housed machinery for the Talargoch Shaft. Nearby, large limestone slabs with embedded metal rods provide further evidence of the site’s former use.

Though most of the mining complex has been lost, a few remnants of workers’ housing and support buildings survive. Talargoch Cottages, originally a row of four miners’ dwellings, have been modernized into two limestone-built homes at SJ 8065 0586. The former mine office, located to the south, remains a private residence, though many of its original architectural features have been altered or lost.

Much of the mining infrastructure was dismantled in the 1960s, with only spoil mounds remaining at SJ 0590 8057

Worked several veins, including Talargoch, Pantons, and Coetia Llys, which ran parallel in a northwesterly direction. These were intersected in the southern part of the mine by string veins, which remain visible on the exposed rock faces of Graig Fawr. Mining in this area can be traced back to at least the early 18th century, with early operations relying on fire engines and waterwheels. By the 19th century, the site had expanded to include several key shafts, including the Talargoch Shaft, Smedley’s Shaft, No.1 Shaft, and the Engine Shaft, the latter equipped with an 80-inch pumping engine.
