The Omai mine extracted high grade ore, to my understanding higher than Smarts/Hicks. The 1.4 g/t figure is somewhat misleading, what they had was an area of high grade veins and waste inbetween with a width of maybe 50m. The only thing they could do was bulk-mine it and so the grade was 1.4 g/t.

Seems there is something similar at depth of Ohio Creek. The mineralized intersections seem to be equal to 4.5 g/t over 20m. True width is still unknown as long as the dip of the deposit is unknown. I assumed the worst case, -90 degree which would mean at -55 degree drill angle 12m true width. But if the deposit has -80 to -75 degree dip true width could be 16m. That compares very favourably with Smarts and Hicks. Grades seem to be way higher closer to surface, I think overall grade could vary between 9 and 4.5 g/t with the wide true width meaning favorable economics regarding strip ratio etc. on top of the grade.
So I assume they have found more than 400k ounces at one of the highest grades for an open-pit mine.

kojack, there is some very high hits deeper down.
2m @ 39.5g/t from 99m
9m @40.5 g/t from 89m inc 6m @ 60.1 g/t

Not to shabby also
1m @ 6.59 g/t from 108m
1m @ 4.4 g/t from 109m
1m @ 9.5 g/t from 115m

cathedrals drilling had
1m @ 868.7 g/t from 61m
1m @ 13.2 g/t from 117m

Obviously more drilling required but looks like good grades down deeper

Also if I recall correctly smarts underground had higher grades
