Mining crystals

Mining crystals are consumables fitted to certain Tech II mining modules to increase the yield of these mining modules, with certain drawbacks depending on the type of crystal used.

Overview

Following CCP's release of Patch 19.11, mining crystals were fundamentally changed. Previously, all ores had their own unique Tech I+II mining crystals. Now, crystals are divided into the into 6 "tiers" of standard asteroid ore types, and the standard moon ore tiers. Within each tier, the crystals are further divided into 3 types with a Tech I & II variant for each type. More information on the differences between crystal types is given below.

Mining crystals can only be used on modulated ore mining modules (any tech 2 module with "modulated" in its name), and increase mining yield when mining a particular kind of ore (but give no benefit when mining another kind of ore). They are loaded into the mining modules (like ammunition) and have a limited lifespan before they break and must be replaced with fresh crystals.

Moon Ores

• : Ubiquitous Moon Ore Crystals
• : Common Moon Ore Crystals
• : Uncommon Moon Ore Crystals
• : Rare Moon Ore Crystals
• : Exceptional Moon Ore Crystals

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	Duration Muliplier
Simple Asteroid Mining Crystal Type A I	I	1x	10%	+0%	0	1.5x	1.0x
Simple Asteroid Mining Crystal Type A II	II	1x	12%	+3.6%	0	1.8x	1.0x

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. The lower duration results in faster extraction.

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

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	Duration Muliplier
Simple Asteroid Mining Crystal Type C I	I	1x	24%	+40%	18x	0.25x	1.0x
Simple Asteroid Mining Crystal Type C II	II	1x	30%	+59%	28x	0.2x	1.0x

Skills

All crystals require their corresponding resource processing skills to be unlocked for use. More information about skill requirements is provided in that link.
