* Resources shown for Carnilya Hill are those attributable to Mincor - that is, 70% of the total Carnilya Hill Resource. ** Otter Juan includes Coronet and McCloy.
Resources are estimated to a 1% nickel cut-off. No minimum mining width criteria are used. The Resource estimation is done using inverse distance or kriging methods, depending on the data density. Volume models are constructed using all available data including underground drive and stope mapping. Grade interpolation using assay results from diamond drill core and, in places, underground face samples.
The information in the table above that relates to Mineral Resources is based on information compiled by Mr Robert Hartley, who is a Member of The Australasian Institute of Mining and Metallurgy. Mr Hartley is a a permanent employee of Mincor Resources NL. Mr Hartley has sufficient experience that is relevant to the style of mineralisation and type of deposit under consideration and to the activity that he is undertaking to qualify as a Competent Person as defined in the 2004 Edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves. Mr Hartley consents to the inclusion of the table on this website based on his information in the form and context in which it appears.

* Reserves for Carnilya Hill are those attributable to Mincor - that is, 70% of the total Carnilya Hill Reserve. ** Otter Juan includes Coronet and McCloy.
Appropriate dilution for the various mining methods was applied to the Indicated and Measured Resources. Using a 1.5% nickel cut-off and minimum mining width criteria, areas were selected as being mineable. Additional modifying factors to account for ore loss, recovery, further dilution etc were then applied to achieve an estimated Reserve.
The information in the table above that relates to Ore Reserves is based on information compiled by Mr Dean Will, who is a Member of The Australasian Institute of Mining and Metallurgy. Mr Will is a a permanent employee of Mincor Resources NL. Mr Will has sufficient experience that is relevant to the style of mineralisation and type of deposit under consideration and to the activity that he is undertaking to qualify as a Competent Person as defined in the 2004 Edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves. Mr Will consents to the inclusion of the table on this website based on his information in the form and context in which it appears.
