1714

Lease of Dyserth mines to a partnership of Staffordshire men who probably introduced the first steam powered pumping engine into the area, but the water problem seemed to be too great. The Governor & Company for smelting down lead with pittecoal and seacoale took the lease of the Talargoch site to rework the surface tips for calamine.

1753

Paul Panton of Bagillt took lease of land between Dyserth and Talargoch for 21 years. At that time the mines all seemed to be in an abandoned state and great expense was incurred in reopening the mines. Panton had leat built in the mid 1750s to take water from Afon Ffyddion above Dyserth waterfalls along a course following the 200 feet contour line to the Talargoch site. This route of the leat caused much contention in later years. Panton acquired leases to land along the Talargoch vein.

1763
