Crimbonium Mine

You probably shouldn't go into a highly-radioactive mine without wearing some sort of protection.

(Shows a Mining system.)

You start digging. You hit the rock with all your might.

You succeed in cutting away some weird, peppermint-scented rock.

You acquire an item: peppermint tailing

then You pan through the rock you knocked loose and collect some Meat tailings.

You gain 24−27 Meat.

or You accidentally inhale a bunch of dust, making your voice sound all husky and cool. And probably eventually giving you cancer.

You gain 9-10 Roguishness.

or This mining stuff is more of a workout than you usually get!

You gain some Beefiness.

or Being down here where it's quiet really makes you think. Or maybe it's the hypoxia setting in...

You gain some Magicalness.

You carve out a nugget of festively-glowing ore!

You acquire an item: nugget of Crimbonium

or

An inexpert shot with your mining laser causes a tremendous cave-in!

You lose some hit points.

You lose some of an effect: Oily Legs (1 Adventure)

Occurs when clicking "Crimbonium Mine" in the Desert Beach.

Notes

You must be wearing the High-Radiation Mining Gear in order to access this area.
There are 10 promising chunks per mine. A contiguous group of 6 promising chunks will be the nuggets of Crimbonium, the other 4 chunks (some of which may be contiguous with the Crimbonium) will be cave-ins. Other chunks will give ~10 of one substat or ~25 meat, in addition to the peppermint tailings.
Mining uses adventures like usual, unless you have the Oily Legs effect (randomly received from flask of mining oil), then one charge is consumed instead.
The Unaccompanied Miner passive skill works as usual, but the Oily Legs effect gets consumed before charges from this skill get used up.
If you have the Crimbonar effect (also randomly received from flask of mining oil), you can see all the promising chunks, regardless of whether you're close to them or not. You can also see all promising chunks with Object Detection, as in any standard mine.
