I think the revised announcement is due to differences in how material exploration results are reported in the North America and Australia. NVA are using US-based consultant geologists to help with the field work and compiling data. So it's probably limited familiarity with the Australia's JORC 2012 reporting requirements. This is also NVA's first reporting of new material exploration results for Estelle - everything we've seen to date has been either interpretation and reporting of historic information or exploration planning.

If you take a look at how material results were reported by Millrock (for exactly the same target/prospect), you can see that there is much less detail in the way results are formally reported to the market. Millrock are Canadian-listed. You can see there is nothing like the JORC table ( which adds 3-5 pages of additional detail to any exploration results announcement ).

compare that generally with the detail of NVA's announcement issued today:
