Have you seen the size of the space stations? The amount of metals and mineral involved in constructing even one of these would take up a massive amount of resources
Yeah Depleted is probably a poor choice. Maybe it should have been a grading "Poor" , 'Medium", "Rich" and "Chockas"
This way, its a rating of the yield rather than using something like Depleted that makes it sound like we did it, rather than it just being a place that has low yield or High Yield
