Most likely any major would have its own internal view and estimates under a range of assumptions.
Most likely any major would have to "officially" adhere to vaild NI 43-101 numbers in order to present and justify any actions to its shareholders.
Most likely any major would only take notice when the valid NI 43-101 brings a project to their threshold to trigger a closer look.

It appears to me that while drill holes not being included could certainly be a cause, that in itself is not the only cause since once one looks at the original and two updates at the same cut-off grade one sees that this estimate lost ground. Perhaps some previously allowed drill holes had to be excluded under the new modelling. However, I believe that the new upper grade cut (20 g/t) and especially the new block size in the model both contributed to reducing the ounce total.
