Interesting to note in a presentation document from 2015 (hope this link works)

https://www.asx.com.au/asxpdf/20151110/pdf/432vhf0n9gdc7l.pdf

The presentation refers to NPV calcs from 2012. A side note suggests that these calcs were done using data from 2004 which was not updated as it was not expected to materially differ. (see page 6 if the above link works)

So the 2012 NPV was based on resource findings / estimates prepared using technology available in 2004?

If so, is it any surprise that with the improvements in technology we are hearing of a significant increase in the resource?
