The classification is an assessment of 'geologic confidence' of the estimation. This is heavily influenced by the data density (drill spacing) and data continuity (a subjectively influenced statistical 'measurement'. the subjectivness can come from how the statistical domains are determined).

No way of knowing what 100m spacing will achieve, because ultimately that will be determined by the CP doing the estimation and classification, and his/her 'interpretation' of the continuity (basically, how they decide to calculate continuity).

My hunch is indicated classification should be able to be achieved for the area with 100m spacing. Measured, maybe not - but possible. I think I remember somewhere Chris mentioning to expect more indicated than measure - but I wouldn't be surprised if we only saw indicated (no measured).
