In its announcement to asx today they mention they are looking into rapid development of Citronen, the largest undeveloped zinc deposit.
As Ironbark looks to fast track the project into production with the commencement of mining targeted in 2013... till date the world largest undeveloped zinc resource is Selwyn resource estimates resource base is 389 Mt, indicated 154.35 inferred 234.15 Zinc (billion lbs indicated 18.2b inferred 23.6b) Lead(billion lbs indicated 6.32b inferred 7.32b)

If IBG resource is the biggest undeveloped zinc resource it should be bigger than Selwyn resource... so the JORC 2010 should be huge
