Just have to rage

Oh, man. Go to Camp Skull Valley, strike at +3, and you'll get more than enough copper ore. For the longest time, I only mined there, and it seemed like I was never getting anything but copper. I actually left to go find zinc.

I know you can get plenty from low level areas, but the original quote was talking about zinc at grade 5, I just meant that you get tons of zinc there but no copper making the zinc useless. similarly with gold sand when you stop getting silver sand.

And as mentioned if you are going to go back to grade 2 where you are goign to get even more zinc, you might as well make the zinc less available grade 5. I have always had an over abundance of zinc compared to copper
