Does this area work in prime and plat? I was told that it did, but I would like to confirm. Thanks,

From 2 minutes ago, in Prime:

[Sea Caves, Tunnel]
Cool wind blows in from the sea and down into the tunnel. Flecks of mica glitter in the walls, floor, and ceiling of the basalt passageway. Green moss grows tentatively across the ground and partway up the sides of the tunnel where the late rays of sunlight fall before the sun goes to its rest. The sound of the pounding surf echoes faintly down the hall.
You also see a wide opening.
Obvious exits: southeast.
Mapped exits: go wide opening

You see evidence of mineral deposits and are certain a good quantity remains to be found.
This area is composed of metamorphic rock layers.
Studying the geology, you are certain that continued mining will be quite safe.
You are certain that marble can be mined here.
You are certain that copper can be mined here.
Miners stand ready to trade resources in for deeds. Just PUSH any mined up stone or metal, and they'll take care of the rest.
