SeaBlock Mining is a mod that adds productivity to the crystallizers, and is intended to make use of the at the time, pointless mining production research. however as sea block has disabled mining prod research (because it is useless), the previous version of seablock mining no longer works.

Updated to reactivate mining productivity research using KiwiHawk's fix. Uploaded for your convenience.

Previous Description:
"Enables the use of mining productivity when using mods with machines that create ore (rather than mining drills). All crystallizers now receive a bonus from mining productivity research, the same way that mining drills do in a normal game. Designed for use with the Sea Block mod pack"

updated to apply to Crystallizer 3 using "Rashino"'s fix uploaded for your convenience.

if Minno or Oncmonkey comes back to the modding community and wishes me to remove this all they need do is ask.
