Mineral Resources Estimate
The Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (the “JORC Code” or “the Code”) sets out minimum standards, recommendations and guidelines for Public Reporting in Australasia of Exploration results, Mineral Resources and Ore Reserves. According to the JORC Code, ‘Mineral Resource’ is defined as a concentration or occurrence of materials of economic interest in such form, quality and quantity that there are reasonable prospects for eventual economic extraction. Mineral Resources are sub-divided, in order of increasing geological confidence, into Inferred, Indicated and Measured categories.
The following Mineral Resource estimate is based on assay data from drill holes at the initial mining area (“IMA”) and surrounds as at 19 April 2010. The Resource Model was released by Golder Associates in October 2010, utilising a cut-off grade of 17% MagFe. “Joffre” is a member of the Brockman Iron Formation, the main ore body for the project.
