A number of large shafts remain visible in the area, including several near Holway Road. At SJ 1786 7634, a shaft sits alongside the road, and at SJ 1794 7630, Garden Shaft remains as an overgrown mound. The Roskell Shaft, which served as a key feature of the Holway mines, is substantially capped with a large concrete slab at SJ 1802 7644.

The mines were drained by the Holway ‘boat level’, begun in 1774, which also served as the main access route for miners. The boat level was used to transport ore via barge but was replaced by a tramway by 1830. The entrance portal of the boat level at SJ 1842 7637 is still visible today, with an iron gate blocking the entrance.

In the 19th century, an 80“ pumping engine was installed at Roskell’s Shaft, and the mines were later superseded by the Milwr Sea-level Tunnel in 1897, part of the Holywell-Halkyn Drainage Scheme.

Processing waste from the dressing floors remains in the vicinity of the stream at SJ 1825 7605. Evidence of buddles and dressing floors is visible, although much of the area is overgrown.

Other surviving features include old stone walls at SJ 1841 7637, possibly forming a building, and three brick-built reservoirs at SJ 1843 7637, which were used for milling activities in the Greenfield Valley. While full of slime and debris, the reservoirs still hold water.

The area has been used as a household dump in the past, but it has now been cleared of debris.

The Holway mines, situated in the northernmost veins of the Carboniferous Limestone Rocks of Halkyn Mountain, were worked from the early 18th century. The Quaker Company initially opened up the large vein that crossed Holway Road, along with the smaller strings branching off it. By the 19th century, the Holway United Mines, including Holway Consols and Great Holway, continued operations east of the old A55 road, in the waste ground south-west of Springhill Farm (SJ 1820 7650). The Holway Rake and the Holywell Level were in operation between 1845 and 1872 near Holway Cottage Farm (SJ 1740 7650), the site of the old whimsey shaft.
