FWIW, there are several example of narrow high-grade Abitibi deposits really coming on-line, WRT grade, at depth.
LOL, it may be that we only hear of the ones that did. But, in any case, these come to mind:
1) Wesdome's Eagle mine, which is just to the SW of the Sugar Zone, particularly Eagle's 300 Zone. (15.3 g/t overall mine reserve grade)
2) Agnico/Kirkland Lake's Macassa, to the NE in Kirkland Lake (16.3 g/yt overall mine reserve grade)
3) Wesdome's Kiena Deeps (most notable example), in Val d'Or (11.1 g.t overall mine reserve grade, but Kiena Deeps is 20+ if memory serves)
I'm not as familiar with the Island Mine, Sugar Zone's nearest neighbor, just to the east. It's currently at 11.4 g/t reserve grade, but they have a large chunk "Island East" as they drill deep, that is 1.9 million ounces inferred grading 20.8 g/t. Slide 18 here:

Some of the other mines of Kirkland Lake, just a few hundreds of meters east of Macassa, ran 18 g/t nearly from the surface, but the currently operating mines, 1-3 above, got rich at depth.
Again, one probably does not hear about the flops LOL. I'm not an expert, do your own DD.
