1★ Isogen Extraction is a Territory research that raises your base mining rate for 1★ Raw Isogen, from 10% at level 1 to 150% at level 15. It unlocks at R&D Department 25, making it one of the first Territory projects you can touch, and one of the best: everything the Territory tree does runs on the isogen you mine.
What 1★ Isogen Extraction does
1★ Raw Isogen is the entry tier of the isogen family, mined from isogen nodes in Territory Capture space and a handful of regular systems, then refined into 1★ Iso-Emulsion, the currency most early Territory research is paid in. This project multiplies your base 1★ Raw Isogen mining rate, so every hour a miner sits on a node returns more raw material for the same effort.

Unlock requirements
Level 1 needs only R&D Department 25. Later levels climb the R&D ladder and pick up Territory-tree prerequisites along the way, all listed per level in the table above.
Cost and research time
Per-level costs are in the table above. Maxing all 15 levels totals about 1.8M 1★ Iso-emulsion, 1.1B Dilithium. The base research time adds up to roughly 14.6 yr on paper; research speed bonuses cut real timers to a small fraction of that, so use it to compare levels, not to plan your calendar.
Is 1★ Isogen Extraction worth it?
Yes, and early, if you play Territory Capture at all. Mining rate research pays back continuously for as long as you mine, and the early levels are cheap. Pair it with 2★ Isogen Extraction once your R&D Department reaches 30, and stretch every refine with Iso-Emulsion Efficiency. The full tree is on the Territory Research guide.
