I found that in my colony 2 having massive ore is not easy for gold it's the same could we have as in the first game a mine
I would suggest you deploy your lander near (but not too far away from ores too) gold deposit clusters.
Maybe you'll need to explore around a bit.
This strategy might help.
Might be a good idea if we add gold mines and ore mines from MC1.
