In the 3D, it states strike of 2000m, widht of up to 400m and depth of 300m.
Trying to calculate the total tonnage of ore.
So 2000 x 400 x 300 x 1/2 x 2.7 (density) = 324mt ore.
Thats approximately 10% the size of Olympic Dam, which sounds about right if it indeed is a smaller scale T1 IOCG deposit.
The question is what will be the average gold grade and hence the total contained gold? Olympic Dam is 0.5g/t from memory.
