Ore production slow

[seturo]

Hi guys,
my ore production is only +0.03. Is this normal? Seems very very slow for me. Maximum output per year is only 3-4?
Thank you!

Apparently the various ore deposits can have density so low at the extreme end that it's actually not worth mining it.
This is in the same vein as making some materials unable to be farmed/cultivated in certain regions, pushing you to trade and making it hard to be fully self-sufficient.

Try looking for another ore vein if you have it in your map. If there are no others, check out the sale prices for commodities you can produce easily locally (clothes, furniture, eggs or caged lifestock - some people swear by buying gems and selling jewellery) and just use the proceeds from those trades to buy ore as needed.

Okay thank you! What a pitty it is the only deposit on the map and I have included all of them in my mine. It is really hard for me to understand, because when choosing the region it showed ~9% ore in the map...
But okay I will skip the mine and just import the ore...

Well, at least it gives you something to play around!

At what output percentage is it not worth investing in a mine? I have a coal field that looked large, but I think only has a 30 or 40% output.
