The Citronen Zinc Project (Project) represents one of the worlds largest undeveloped zinc resources. The project is located in northern Greenland, a self governed part of the Kingdom of Denmark and has a low level of sovereign risk.

Ironbark completed approximately 11,000m of diamond drilling at the Citronen Project in 2008 bringing the total metres drilled for the Project to 44,000m. The current resource (September 2008) for Citronen is:

•    Global Resource            -  101.7Mt @ 4.7% Zn + Pb at a 2% Zn cut-off
•    Medium Grade                -  56.0Mt @ 6.1% Zn + Pb at a 3.5% Zn cut-off with a
•    Higher-grade core of     -  22.6Mt @ 8.2% Zn + Pb at a 5% Zn cut-off

The mineralisation is considered to be of a SEDEX style zinc deposit and this model is potentially very large. The mineralisation starts from surface, is shallow, flat lying and adjacent to a deep water fjord that may provide near mine ship docking and loading opportunities.
