It looks reasonable to guestimate that the GM is 8 km long, 1 km deep, 0.5 m wide with an average grade of 3 g/tonne. This will give about 1.1 million ounces of gold.
With the other strikes in that general area, the tonnage easily adds up.
The question is if it is economic or not! The veins are narrow and not of spectacular grades.
The NR as usual came up with lots of potentials, but each property is sufficiently far away from each other to not allow for too much synergy between various potential operating mines. This means that each region has to be economic on its own rights.
So for me right now, the big questions are if 1) the GM can be economic and 2) will some of the other promising targets shine even brighter.
I personally would not spend big money on the metallurgy and recoveries of the gold, if the ore is not too different from other ores.
