Connemara Mining is expanding its exploration work close to the Lisheen zinc mine, capturing additional geological data as it tries to locate new resources.
The company, whose chairman is John Teeling, holds three licences around Thurles, Co Tipperary, close to the mine, which is operated by global mining giant Vedanta Resources. The Lisheen mine is one of Europe's biggest producers of zinc concentrate.
Connemara said that it has already completed a significant amount of work on the block where it holds its licences.
That activity included the drilling of four exploratory holes in 2012. No minerals were discovered during that drilling, but the company said it revealed "positive structural indicators".
Connemara is also engaged in field work at its Donegal block of 10 licences where it hopes to strike gold.
"The Thurles exploration programme is designed to better identify potential drill targets while the Donegal exploration is designed to give a general understanding of what might be there," said Mr Teeling.
