I presume that because ~50% of the deposit is already classified as Indicated resources (as opposed to lower confidence Inferred) that the expert that produced the current resource thought there was enough continuity demonstrated by the current 20m spaced drilling to justify that higher classification.

The company might argue the new 10m spaced sections was to allow them to upgrade to Measured resources.

In the world where money is not an issue you would NOT be seeking to upgrade Indicated to Measured now - you would be out exploring for more ounces - new deposits / extensions etc. Many pits are designed, funded and mined with a fair amount of Indicated resources.

In the real world money is an issue (ie: NTM didn't have much) so we can probably call it for what it is - drilling holes in the most likely place to get a share price response to allow the company to complete a CR.
