Most of the commercially exploited and exploitable Irish lead zinc deposits have been discovered in a NE – SW band of Carboniferous stretching across the centre of the country. The deposit types tend to be carbonate hosted such as the Lisheen mine in Co. Tipperary or a combination of Sedimentary Exhalative (SEDEX) and carbonate hosted deposits such as the Navan deposit operated by Tara Mines.

Belmore Resources’ 100% owned Clare block licenses are located in this most prospective carboniferous region and are host to the historical Ballyvergin copper deposit, discovered in 1957. This deposit marked the start of modern mineral exploitation in Ireland. The licenses are also on trend with the Tynagh zinc-lead-silver deposit which was discovered in 1961. It was this discovery of Tynagh that sparked interest for exploration for Lead Zinc deposits in Ireland and in 1962 the Silvermines deposit was discovered which lies just 30km to the east of the Clare Licenses.
