Black are the more recent drills.




See North Uphill extending out of the inferred blocks, while usually the inferred would extend X meters past the nearest intersections. So I expect the inferred to extend further uphill after MRE, which would be good for replacing waste with ore in the pit design, but needing to upgrade that part from Inferred for use in PFS.



As for Valley, it's a bit harder for me to predict whether the inferred will expand, as the intersections are sporadic - potentially similar to what the inferred had already assumed.

For South, the inferred will likely be cut back on the eastern slope, but extended in the downhill direction. Potentially allowing the pits to merge into one. South delivered a little in the downhill direction, but combine that with North Uphill delivering a fair bit (consistent and quite good grades, but not testing particularly far uphill yet). That removes some waste from the pit design, improving strip ratio, maybe allowing it to become larger (merging into one, but that's a while away, with PFS requiring more Inferred upgraded to M&I).
