The 19th century was a period which saw Cornish mining technology used to deepen some of the mines in search of richer ore deposits. However, as the lead veins narrow with depth, this proved unsuccessful, and attention was switched to resmelting the lead-rich waste slag and slimes left over from previous medieval mining.
Large deposits have been extracted from mines in Navan, Galmoy and Lisheen. The mines in Galmoy in Co. Kilkenny and Lisheen in Co. Tipperary have ceased production in recent years but Tara Mines in Co. Meath is still in operation. At its peak Ireland was the largest producer of Zinc in Europe and the second largest producer of lead.

Commercial production of zinc did not start in Europe until the middle of the 18th century and in the United States until 1860. Zinc metal has never been found naturally. The great majority of zinc deposits contain the lead mineral, galena, and both the lead and zinc minerals are mined together.
