The B-Zone 4611 Silver-Rich Pod—An Unusual Ag-Ge-Sb-As-Ni Assemblage Within the Irish-Type Zn-Pb Silvermines Deposit, County Tipperary, Ireland Open
The Silvermines Pb-Zn-Ag-Ba orebodies comprise vein, replacement, cross-cutting and stratiform mineralization mostly hosted in Lower Carboniferous limestones in the vicinity of a major ENE and E-W trending normal fault array and represent …

Irish-type Zn-Pb deposits - What are they and can we find more? Open
Seven carbonate hosted Zn-Pb (+/-Ag, Ba) or Cu deposits have been mined in Lower Carboniferous limestones in Ireland since 1960 - representing a resource base of ca. 22 Mt of metal (Tynagh, Gortdrum, Magcobar, Silvermines, Navan, Galmoy an…

Ore depositional processes at the carbonate-hosted Tara Deep Zn-Pb deposit, Navan, Ireland Open
The Tara Deep Zn-Pb deposit (currently 26.2 Mt @ 8.4% Zn, 1.6% Pb) is the latest major discovery by Boliden Tara Mines (first announced in 2016) which significantly adds to the existing world-class Navan deposit. Located 2 km south of the …

Coupling Mineralogy, Textures, Stable and Radiogenic Isotopes in Identifying Ore-Forming Processes in Irish-Type Carbonate-Hosted Zn–Pb Deposits Open
Irish-type deposits comprise carbonate-hosted sphalerite- and galena-rich lenses concentrated near normal faults. We present new data from the Tara Deep resource and overlying mineralization, at Navan, and the Island Pod deposit and associ…
