Mineral costs for slipways and additional capacity?

[Graymane (OP)]

Are there any mineral costs associated with expanding shipyards?  I would assume so, but where do I see the cost?

Yes, there are costs - I have found my dockyard expansions halted due to lack of them.  I believe the minerals required are Duranium and Neutronium.  I do however not know where to check, or what amounts they cost.

I believe it's 50/50 of the above mentioned minerals. You get an idea of the cost look at the cost to add a slipway or to add 1000 tons. It will be half of the cost in Duranium and the other half of the cost in Neutronium.

It's exactly 50-50 Duranium and Neutronium. Slipway cost depends on the size of the shipyard.
