I'm looking at the announcement of 28 November 2018.

Read the 4 paragraphs above table 2, look at and read that table and read this paragraph in particular.

"The Gilbeys grade control drilling took place initially from natural surface ~ 430 RL and then from the 400 RL predominantly in the major Gilbeys southern pit extension where mining is more advanced, and has provided detailed information on a 10m by 7.5m pattern infilling the approximately 25m by 25m pre‐mining resource drilling. The grade control drilling extends to approximately 360RL (~65‐70m below natural surface), and the re‐modelling extends its influence to around 345RL."

If the grade control drilling only extends to 65-75m below natural surface how can it say anything about the grades below that? The modelling extends 15m below RL360 to RL345, ie to about 90m below surface.

Now look at the typical cross-sections of the Gilbey's mineralisation shown on page 11 of the 2016 Dalgaranga feasibilty study.

The deposit extends to depths of below the RL200 level. That is 145m beyond/below the limits of the grade control drilling/modelling or to a depth of 230m below the ground level. Then look at the figure on page 14 of the same feasibilty study. It shows the pit shell in the feasibilty extending to the same depth, ie down to the RL200 level, ie a depth of 230m below the ground level. Most of the indicated resource also extends to this depth with some of the indicated resources going beyond the planned pit floor, 230m below ground level.

The reference to 85% in the fourth quote in your post is a reference to the Gilbey's deposit comprising 85% of the global resources of the project when you include the other pits/deposits, it doesn't refer to the proportion of the Gilbey's resource tested by the grade control drilling although no one would blame anyone for making that mistake when reading that extract.

The grade control drilling can say nothing about what is below the 360RL level (ie 85m below the ground level) because that was the depth of the drilling. Esh
