Galantas Gold shares rose strongly on Thursday after the firm announced the "game changer" news it has been granted planning consent for an underground gold mine in Ireland.The planning consent will permit the continuation and expansion of gold mining and is expected to create hundreds of jobs locally.The consent includes operating and environmental conditions, which the company anticipates mostly to be based upon guidance already noted in consultation.The group's chief executive officer Roland Phelps said: "This is a significant milestone and a game changer for Galantas."Our open pit gold mine, operated until recently, is the only one in Ireland. "It had excellent environmental standards, monitored with detailed studies by the Northern Ireland Environment Agency and used a safe processing methodology to produce a smelter concentrate."The share price had soared 28.85% to 7.57p by 13:59.
