Main entrance is at SJ 1295 7950, workings extending across pasture and woodland near Bryndigif Farm (SJ 1275 7945).

A large isolated shaft lies west of the farm at SJ 1262 7942, with multiple shaft mounds to the east and in surrounding woodland. The vein was worked further east, with numerous early shafts scattered across fields, some fenced off but others barely visible. A more easterly shaft is at SJ 1385 7920 near Nant Evan.

An adit level driven from southeast of Pentre-ffynnon Farm remains unlocated.

• 1720s - The Quaker Company, which dominated 18th-century lead mining in Flintshire, leased Brindigrif from the Mostyns.
• Worked by Mostyn Consols from 1882 to 1884.

Accessed via a track from Maes Achwyfan Crossroads, with a low stone wall running parallel to the woods.
