The Specifics cover all available mining locations. Okinawa still provides Helium-3, but players will only be able to gather it in Sigma-13. The same goes for other fields and other ores.
The Hegemon is already able to solo-mine at good efficiency, but only able to carry 2750 units of ore maximum. For anything else, mining should be cooperative action, hence why the route duration accounts for mining time twice. Having more ships like the Hegemon is something I'll consider for the future.
