Questions about ore and mining

[mdlp0716]

I am trying to mine on the Mun, and using the orbital scanner, i set the cutoff to 70% and found a good spot to land. When I landed, I used the surface scanner and it said 2.34% concentration. I tried again with another spot, and it only said 7%. Why is it saying 7% when the orbital scanner said 70%? Is there any way to get the concentration up even higher?

70% in orbit means "70% of maximum concentration", not that the ground is literally made out of ore.  Given the figures you've listed here, the maximum must be around 10%.  Which sounds about right for a stock game.

Might want to have a look in the Tutorials subheading of this very forum.

This should help.
