“We are delighted the Citronen project has been ratified as a base metal mining project of global significance,” Ironbark Zinc managing director Jonathan Downes said in the company’s announcement to the Australian Securities Exchange.

“Located in Greenland, a nation actively seeking to foster a mining sector to help support its economy, Citronen’s mine life of at least 14 years is defined only by the limits of drilling to date.

“As such, one of the project’s most exciting aspects remains its exceptional exploration potential with identified mineralisation remaining open in almost every direction.”

The Feasibility Study incorporated a recent review of capital costs and the company’s 2012 updatedResources Statement.

Further advances and improvements, particularly surrounding resource confidence and mine scheduling, were released in 2012 were also included in the Study.

The company said it has achieved recent metallurgical breakthroughs with zinc flotation recoveries of 90 per cent.

Ironbark explained this testwork remains ongoing and as such, the results cannot be included in the Feasibility Study until it has achieved feasibility- level engineering confidence.

The company indicated these higher recoveries will be incorporated into the Feasibility Report following the completion of further studies.
