Mining crystals are special consumables fitted to Tech II mining harvesters and Deep Core mining lasers to massively increase the yield of these mining modules, with certain drawbacks depending on the type of crystal used.

Crystal compatibility

Following the release of Patch 19.11, mining crystals in EVE were fundamentally changed. Prior to Patch 19.11, every ore had its own unique Tech I and II crystal. Now, standard ores are separated into 6 "tiers" with each Tier having 3 types of crystals, further divided into their Tech I and II variants.

Moon Ores

Moon mining crystals only have a visual change to put them in sync with asteroid crystals, and are still compatible with the same tiers of moon ores (ubiquitous, common, uncommon, rare, exceptional) as crystals pre 19.11. See moon mining for more details on specific ores.

Crystal types

Type A

Type A crystals have moderate yield and residue bonuses, and are the most balanced crystals for standard mining operations.

Crystal Tech Cycle time Volatility Residue probability Residue multiplier Yield modifier
Ore simple crystal A I.png Simple Asteroid Mining Crystal Type A I Tech I 1x 10% +0% 0 1.5x
Ore simple crystal A II.png Simple Asteroid Mining Crystal Type A II Tech II 1x 12% +3.6% 0 1.8x

Type B

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.

Crystal Tech Cycle time Volatility Residue probability Residue multiplier Yield modifier
Ore simple crystal B I.png Simple Asteroid Mining Crystal Type B I Tech I 0.9x 15% +20% 0 1.5x
Ore simple crystal B II.png Simple Asteroid Mining Crystal Type B II Tech II 0.8x 19.6% +30% 0 1.8x

Type C

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.

Crystal Tech Cycle time Volatility Residue probability Residue multiplier Yield modifier
Ore simple crystal C I.png Simple Asteroid Mining Crystal Type C I Tech I 1x 24% +40% 18x 0.25x
Ore simple crystal C II.png Simple Asteroid Mining Crystal Type C II Tech II 1x 30% +59% 28x 0.2x
