An important lead mine with a number of shafts, extensive tips and tailings heaps, buddle pits, together with a number of mine buildings including the remains of a Cornish engine house and boiler remaining on the site.
Llanfyrnach was by far the largest of the Pembrokeshire mines, and of the south Wales mines, second only to Carmarthenshire's Nantymwyn Mine in terms of the recorded output. A reference in the Mining Journal (1879) notes a well-defined east-west lode made up of sugary quartz and containing a good deal of lead, and about 150 tons of lead ore being delivered monthly from this and the old lode. Very little sphalerite was sold until the final few years of its working. Silver was extracted from the galena.
Llanfyrnach was said to have already been of considerable extent by 1764. By the time of its closure in 1891, workings had reached a depth of 96 fathoms.
Despite an account of a visit to the mine (Mining Journal - 1873) referring to the fine crystals sometimes discovered, there is unfortunately little evidence of this to be found on the dumps.
The hamlet of Llanfyrnach lies in the parish of Llanfyrnach.
