Buried resources, Portable Drill and Mining Drone#121

Around the map, Tthere would be buried resource nodes that are not harvestable (tells you “need special equipment” when looking at it) ; these could even come to replace the big “ore rocks” that just indicate that there are ores of this type nearby. To extract the materials from there, you would have to use a portable drill on it to obtain the resources.
Each buried node would have a set amount of resources (random, between 20~50) which the drill tells you when placed down. The drill would have about 1 slot of inventory but with 30 or 40 max items, so if the node has more than this, you’ll have to pick the resources up before it can continue drilling.
The portable drill would be unlocked at Tier 2.

It would give a new source of raw materials, but with a coal tradeoff.
It would take :

• 1 coal to extract 20 copper in 2 mins
• 1 coal for 15 sulfur in 2 mins
• 1 coal for 15 iron in 2 mins
• 1 coal for 10 crystal in 2 mins
• 1 coal for 10 titanium in 2 mins
• 1 coal for 5 diamonds in 2 mins

Enemies could take the resources inside it, or just destroy it. (They can’t pick up the drill itself). For COGs, unless their AI gets massively improved, they would probably just shoot at it on sight.
When a portable drill is destroyed, it leaves a small wreck on the ground that can be recovered for a bit of scrap metal, and if it had resources in it, there would also be a small box that contains said resources.
If there is an eruption and it is still on the surface, it will be destroyed.

The mining drone (#45), which would have to be unlocked at Tier 3, will be a great alternative : As we know, it goes to mine ore deposits near the ship automatically. However, it would also have the ability to collect resources from these special, big nodes ! It’s an upgrade from the portable drills in the sense that it will automatically go there and come back, take energy from the ship directly, etc. So it will be much more efficient and easy, you don’t even need to interact with it.
But there could always be some buried nodes farther away from landing sites, so mining drones could not reach them, and really greedy players could always find more, even if a ship already took all the resources near it. That would make the portable drill not entirely irrelevant.

Note : what I was thinking of when I say “portable drill” is something like the one like in Satisfactory.

Edited the post to make some things a bit more clear.
