I agree. But what I hadn't picked up earlier was that they have dug 2 holes in L71 and pulled about 2000t from each, hence the 4000t which is all from L71.
I'm not sure if they have dug one or two holes in L72. Would probably make good sense to keep the rock from each pit separate though, so it will probably be mid next week before all rock is processed.

From June 26:
The L071 kimberlite sample will be the first of the kimberlites in the Canguige catchment area to be
bulk sampled (Figure 1). L071 is estimated to be ~30ha in size at surface. Two bulk sample locations
have been chosen at L071, where the completed delineation drilling showed the targeted
volcaniclastic kimberlite (“VK”) was hosted.

It appears to me that L72 excavation had only just commenced at the AGM presentation, I think the two holes in that presentation are both L71. The L72 hole looks like a pentagon in the 10 Aug announcement.
