Type A crystals have moderate yield and residue bonuses, and are the most balanced crystals for standard mining operations.
Type B crystals have much improved yield bonuses, however, they also get a correspondingly high residue probability level to match. These crystals therefore will have a high mining yield but waste more ore in the process. The lower duration results in faster extraction.
Type C crystals are not for standard mining operations. They have extremely low yields with extremely high residue, making them suitable for strategic ore removal or for offensive mining operations against hostile player space.
