I was flying in East Limerick the other day and saw dozens of drilling rigs in operation, in farmland around the N24. A friend of mine who has land there was asked to allow drilling on his land and he declined when they wouldn't tell him what they were looking for and the drilling rep was very cagey. Rumour has it that there is a very large zinc deposit in the area. Has anybody any ideas or info about this operation? My friend is of the opinion that landowners do not own the mineral rights under their property. Is this true?
