Ironbark owns the Citronen Zinc-Lead Project in northeast Greenland. The Project lies within the the Paleozoic Franklinian Basin in northern Greenland. This sequence of Ordovician (~400Ma.) rocks spans roughly 2,000km, running E-W across northern Greenland into northern Canada. This stratigraphic sequence is well mineralised with base metals (zinc-lead-silver) and hosts several Mississippi Valley type (MVT) and SEDEX type deposits.
