Ok - the POS is pretty much setup for construction now.
We're short on some of the minerals however - the most urgent being Zydrine (40k) and Megacyte (16k).
We are however in a region with Arkonor, Crokite, Bistot and Spodumain

According to my calculations - we need 16k of Crokite & 13k of Arkonor to obtain the volumes above.
Now ideally we can get this from a hidden belt - but that requires chance and it isn't a sure steady supply.
The nearest unrestricted system with crokite is 6/7 jumps away - and there are 2 restricted systems (2 [D-Q04X] and 3 [V6-NY1] jumps respectively) that have it.
I'll try to grab a SOT diplomat to see if I can arrange mining rights in those systems.
Now the volumes of Crokite & Arkonor are pretty large - so a standard hulk will only be able to hold 500 ore units and we would therefore need either the Rorqual or a maxed hauler.
Using a hauler is possible but introduces extra risk (due to the manual jumping needed) - the Rorqual can single jump between the POS system/office and the remote systems.
The unrestricted systems further out would need to be checked to see if they are cyno-jammed.
Otherwise we may need to see about setting up a small POS in WMH-SO or Y-2ANO. Jumping in the Rorqual without having a POS would be risky.
Update: Contacted one of the diplomats in SOT about mining in the Minotaur constellation (http://evemaps.dotlan.net/map/Fountain/Minotaur) and he's passed it up the food chain and will contact me when he has an answer.
I'll offer them a % of what's mined (I was thinking around 10%) in return for the rights to mine there.
