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?

when i need to change my orbit to get to the Mun ill be fine and everything but once my liquid fuel runs out i will press space to go to the next stage and it wont work, so im left floating in space unable to complete the tutorial.
