grade of ore at chambishi mine

Nov 28, 2018 Im trying to research Prime Hulls, and to do that you need 125 Uncommon Grade 3 Ore. Im at level 14 and still working on research and upgrades. I found some Raw Grade 3 Ore, but my refinery lacks the option to refine grade 3. I only have grade 2 available. Is there something needed to make it available?
