A quick, yet thoughtful suggestion:
Every other Unguarded mine has access Minerals, Ore, HQ Minerals, and HQ Ore, except the Broken Hills mine.
Broken Hills has three different places to mine Uranium Ore, but it has no places to mine regular Minerals.
(Of course, if you have seen and tested a spot that already has regular minerals, please post a screen-shot of it, or very good description of where it is at.)
Currently, if you take the top passage after you enter the Broken Hills mine, to your right (as you go up the top route) will be a Uranium rock-slide at the beginning.
Now for the suggestion:
I suggest we change this spot Uranium spot to regular minerals, and leave the two other Uranium spots as is. I think that all unguarded mines should have access to both types of minerals and iron ore. Redding has regular minerals and ore, and so does Gecko, but (as far as I know) Broken Hills does not.
(I don't have a picture of the spot at the moment, hopefully you know what spot I am talking about, I'll add pictures later)
