Resource Estimate
The Rio Blanco resource was calculated by Snowden Mining Industry Consultants Pty Limited. It is classified according to the Australasian Code for Reporting of Mineral Resources and Ore Reserves (The JORC Code) prepared by the Australasian Institute of Mining and Metallurgy; the Australian Institute of Geoscientists and the Minerals Council of Australia.
The following table summarises the Rio Blanco resource at a cut-off grade of 0.4% copper. The resource is located principally at Henry's Hill, with a small contribution from the adjacent Soho deposit. The estimate is based on 53,000 m of diamond drilling (157 drill holes) & samples from two adits.
