Exploration company Minco says recent drilling at its Pallas Green site in County Limerick has revealed the highest grades of lead and zinc found at the project so far.
The drilling was at the Tobermalug Prospect. Minco has a joint venture with Xstrata at Pallas Green.
Minco's Terence McKillen said the company was delighted with the 34.56% grade encountered, and further drilling would take place shortly.
