Natural Resource Company

When building a natural resource company in your country it doesn't give a choice on which one of them to start on.

Example
mining Coal 1,434,120,000 ton
mining Coal 1,744,200,000 ton
mining Coal 16,279,200,000 ton
mining Coal 16,279,200,000 ton

This is my list for coal. I'm guessing it picks the first on the list to start mining. Is this correct?

I would like to create a company to mine one of the last two. Or does it automatically pick the largest pocket?

I want to say that Andy said it automatically picks the largest one, but it's been too long since that forum post. At any rate, you don't really need to worry about it, since the amounts of these resources are just so grossly high that it's not going to matter. The lowest amount of coal on that list will last 296 days at 100% production. That's like 6 real life months. In 6 real life months, if you've managed your country well, there's a decent chance you will have started mining corporations to take advantage of the rest of those coal resources.

Great answer, thank you

I do not remember saying that it picks the largest one but I could be mistaken.

I would suggest you build all of them. They will produce very large profits and remain in business for sufficient time to recover the setup cost many times over.

Look around and you will see that countries and enterprises with many natural resources corporations are very profitable.

From the last resource company I made it did not pick the largest deposit of resources.

How long does it take for natural resources to replenish once they have been used up? I notice they tend to come back but don't remember how long

One, from my recent builds, it appears entirely random which resource is chosen.

Two, replenishment, according to game news, appears to be whenever the gamemaster decides so.

The choice of resource is a random function.
at the end, if you want to achieve max results, you will use all the available resources.

All the natural resources corporations have the potential to be very very profitable.
they all run many game years and produce profits of 3+ billions per game month.

The used resources are never replenished and there is no documentation saying otherwise.
when all used, the natural resource is depleted and the corporation is closed.

The only way new resources are added to countries is by rounds of discovery that are run by a game procedure from time to time and add many resources, at random, in (probably) all countries.

Currently, there are many unused natural resources. Tens of thousands were added in many rounds of discovery.
Most C3 countries have a very large number of unused resources and some have more than 100.
