Mine

If you follow the old road west from Slagtown, past the chemical plant, past the truck stop, and even past Lurleen, eventually bombs start getting thrown at you.

That would be your cue to book it north, and hope that you can climb. After a 10m climb up, you can enter the Old Mine.

Denizens

The mine itself is home to some of the following post-apollyonic critters:

First Level
bats
cave rats
chukkas
bandits

Second Level
chumans
chukkas
giant spider

Third Level
chimaera

Goodies

There are two mutations located in the mine; low-xp players may want an escort or, failing that, to put everything in their safe deposit box and just suicide-run it.

There are also a reasonable amount of items just lying around.

Item name	Abundance
iron ore	very common
quartz	uncommon
rough peridot	uncommon
