Ireland is one of the top ten producers of zinc, globally, and that zinc comes from only a handful high grade, underground mines. But if you think that exploration for zinc in Ireland is small fry, think again Xstrata, Anglo American and Canadian giant, Teck Cominco are all in the thick of it; and the reason they are in the thick of it is the high grade nature of Ireland's zinc deposits.
Arguably the most famous zinc mine in Ireland is Navan, which was discovered in 1970. Navan had an impressive 70 million tonnes of reserves, grading 10% zinc and 2.5% lead, when it went into production, and it's still one of the top three underground mines in the country today. Amazingly, after Navan in 1970, no further discoveries were made for 15 years, until the Galmoy discovery in 1986. Galmoy, like Navan, had eye popping grades 6.2 million tonnes @ 11.3% zinc and 1.1% lead. Just four years later, a third mine, Lisheen, was discovered, holding 18.9 million tonnes @ 12.5% zinc and 2.2% lead. So why the history lesson? Simply put, the name of the game in Ireland is grade - high grade; and that is exactly what Connemara Mining has hit in Limerick.
