Shafts remain visible on land now occupied by a static caravan park and can be identified both within the park and in the woodland of Coed Mawr at SJ 1974 6536, SJ 1981 6537, SJ 1982 6535, SJ 1971 6523, and SJ 1943 6541. A series of leats, constructed during the John Taylor period in the early 19th century, supplied water to the mines. The system diverted water from the River Alyn at SJ 1968 6282 and ran through the Llynypandy sett to the Pen-y-fron sett at SJ 1986 6623.

Llynypandy Vein runs east to west through Carboniferous Limestone. The earlier Rhydalyn sett was later absorbed into the larger Llynypandy Mines, becoming known as South Llynypandy. The mines were eventually drained by the Halkyn Tunnel, which reached the sett by 1901.
