==Minerals Quantity & Accessibility==
Every world has a chance to contain some of the TN-Elements, each with a specific quantity and rated at a level of accessibility between 0.1 and 1, which dictates how quickly the mineral can be harvested with any given quantity of mining equipment. Very massive planets are likely to have large number of minerals available at very high quantities but low accessibility, while smaller worlds, moons and asteroids are progressively more likely to have fewer minerals at higher levels of accessibility.

Minerals Accessibility value is multiplied by your annual mining rate to give the total amount for that mineral that you can mine. So if your mining rate is 12 tons/year and the accessibility of a mineral is 0.5, you will mine 6 tons/year. 

For planets and moons, if a mineral's accessibility is greater than 0.1 it will begin to fall once you have mined out half the mineral. The accessibility will reach 0.1 shortly before the mineral deposit is exhausted
