undercalled gold in gh sample, page-5

Nabaru, agree with your comments.

"Having no cut would ring big alarm bells to me."

What do you think about ABU reporting OP resources with no top cut? (yes Chuk, I am aware they also report top cut values too).

Lots of methods for top cut analysis. End of the day, it depends on the quality of your domaining (the geo's work) and the statistics of the gold population distribution within that domain. End of the day you want to minimise the amount of metal lost, while at the same time decreasing the COV of the population to something that will still result on a good resource estimation.
