An exploration firm has struck gold in the southeast in a find that could be worth tens of millions of euro.

The IMC Exploration Group says it has found "exceptionally high" levels of gold during exploratory drilling in north Co Wexford.

The mineral prospector says the encouraging quantities of gold found at the test site could result in a gold mine being opened in the region in the coming years.

IMC has been awarded 21 mineral prospecting licences by the Government over the last three years - three gold and 18 base metal licences.

IMC Director Neil Ring has said the find could be the biggest of its kind in Ireland.

"The concentration of gold per tonne in the sample we have had assayed is 11.3 ounces," Mr Ring said.

“Now to put that into perspective, the Clontibret find in Monaghan is 1.24 grammes per tonne. 11 ounces is 354 grammes, so it's a very significant high level, high grade find."
