Add More offshore mining

Like we have sulfur, and quartz. add some more like iron. coal. copper. Limestone. Rock. gold.
(dirt maybe and sand to)
that way we have more options to get those resources instead of mining, or only trading for them
i’m not sure if any of those exist yet since I have not found any others than the sulfur and quartz.
Thank you for reading!

Idk why you would want this when there are many contracts already available that are much cheaper on unity and workers

Sand can be created from Quartz by processing it in a Crusher twice.

I prefer it how it is, but more trading options would be good.
Currently, it forces you to adopt recycling and consider you trading options for when island ores run out. I like that.
I find i need very little ores late game when recycling is maxed. Just need lots of sand and limestone which is easier to import.
I would like better landfill import options though, sea reclamation slows prohibitively late game once youve levelled everything, last game i had rock, quartz and limestone importing at ridiculous rates but not enough.

I hope it gets added soon. Contracts are nice and all, but importing is way easier and can provide more volume. Considering there are already uranium and coal mines on the map it wouldnt be too much of a stretch.
And whoever would not like it can just not use it
