History

See also: Citronen Fjord

The Ironbark company listed on the ASX in August 2006 as Ironbark Gold and in March 2007 acquired the Citronen Project.^[1] To reflect its core focus on zinc and the Citronen Project, the company changed its name to Ironbark Zinc in November 2009. Ironbark's goal is to develop the Citronen Project into a major base metal mining operation in Greenland. The project hosts in excess of 10 billion pounds of zinc and lead, and has a JORC-compliant Resource of 55.8 million tonnes at 6.1% zinc and lead.

In 2013, Ironbark completed a Definitive Feasibility Study which confirmed the Citronen Project's development potential and in October 2014, the company submitted a Mining License Application for the project. Ironbark has a non-binding Memorandum of Understanding with China Non-Ferrous Metal Industry's Foreign Engineering and Construction Co. Ltd. (‘China Non-Ferrous’, ‘NFC’) for the construction and financing of the project, which provides NFC the option to purchase 19.9% of the Citronen Project and the right to enter into an offtake agreement for a portion of the project's concentrate at such time it is in production. Ironbark has strong and supportive shareholders which include Glencore International AG and Nyrstar NV.

Development remains contingent on securing financing. Ironbark signed a memorandum of understanding with China Nonferrous Metal Industry’s Foreign Engineering and Construction Co. (NFC), under which NFC would provide engineering, procurement, and construction services, could secure offtake rights to the concentrates, and potentially acquire up to a 20 % equity interest in the project.^[2]

A 2025 report by industry analysts remains highly complimentary, reaffirming Citronen’s status as one of the most significant undeveloped zinc–lead deposits globally, and underscoring Ironbark’s strategic positioning in Greenland’s mineral sector.^[3]
