Not sure I like the tone of your request
@bigdaddymoney... perhaps you meant 'unspin this 2ic'?
The header really says nothing substantial about whether the infill drilling has improved or downgraded the MRE model, and thus ultimately the Mine Reserve (to be updated fully in March Qtr which seems a long way off for fairly simple update). Additional detail, "largely confirming", significant intervals are all quite meaningless motherhood statements really.
Similar wording in the 2021 Grade Control drilling release, which never turned into a market MRE or Mine Reserve update.results were kept in house and last Qtr no reference ws made to how all-important actual production reconciled to the Mine Reserve model?? Frankly it reads the same and means the same... nothing inn the context of mine issues they are currently facing.
2021 Grade Control infill drilling (planned to cover first 2 years) are black dots in northern area, much of which has been left behind in the new East Dune only mine plan. You can see the requirement to extend infill drilling south now, especially down the south where they are already about to move beyond infill drill coverage.
The Cross-Sections THM scale is woefully inadequate for a very low-grade deposit (a conscious decision to avoid clarity imo). A scale in 0.5% increments would be more revealing of the actual grades, where as 0.5-1%, then 1-3% is almost useless for an average 1.2% MRE deposit. Even 0.5%-1% can be misleading as to whether THM is closer to 0.8% or 1%, which is a 20% range in itself.
Top section A-A' has added some useful deep strands inbetween the old pit designs, but also doesn't look encouraging further west with thick overburden to reach 1% THM average grade ore, especially with water mounding issues out west. The Lower Dune-strand Unit variably extends across the deposit as we know, and variably, intermittently extends along strike (as per bottom image 2018 MRE). By definition almost, the old drill section immediately north of Section A-A' is probably weakly mineralised or it would not have been left closed off and not drilled in previous pit-design. This is why MRE catagories move from Inferred, to Indicated, to Measured with more detailed rilling and less 'guessing' or risky mathematical interpolation. Only a detailed MRE computer model update and comparison with pre-exiting MRE can reveal what the over-all difference and changes to any pit designs will reveal (including possible mineralogical implications of more detail met comp samples).
Section B-B' out east is in an area with thick Upper Dune sands of good avg grade, over high-grade Lower Unit strands... which is partly why the new mine plan has headed solely down the East Dune as I pre4viously explained (basically high-grading the deposit in a fight for life).
Finally, the 2022 Mine Reserve Upgrade new Pit Design compared to the pre-mine DFS Pit Design are shown side-by-side below. We now know the 2022 Pit Update (based on 2021 Infill Drilling) produced smaller, patchier mine pits than the market was led to believe from the DFS. Obviously more infill drilling will be required moving south to provide confidence to the pits over very wide spaced rill sections. More detailed mineral met work over the Upper vs Lower, West vs East ore may also be helpful...
