Mining Rules in 3.x or Pathfinder?

[Endarire]

Greetings, all!

Are there any official rules for mining (effectively digging the ground) to excavate valuable materials, like gems and ore? Basically, if I dig for an hour in environment X, what charts are there to determine what I find/excavate? If not official, what are the best homebrew rules around?

I ask because I'm interested in making a character who starts out mining, then opens a business, and adventures on the side. I was pondering Warblade due to fighting skills and the STR focus being logical. I'm aware of the official business rules from Dungeon Master's Guide II and Frank & K's revisions for these business rules.

I'm also well aware of the combat side. I'm specifically after mining rules.

If you're just mining by yourself, use the profession rules and take Profession (Miner). Not sure about running a business.

Are there any tables, charts, or/and rules that are significantly more specific than just a Profession check? I mean finding a dig site, determining its worth, excavating it, hauling stuff to market, fighting off intruders, building supports... that sorta thing.

Such rules existed in the First Ed Dungeoneer's Survival Guide.

To the best of my knowledge and understanding, nothing like them has been reprinted since.

The rules for Profession (Mining) are in Races of the Dragon.

Yeah, use Races of the Dragon to determine progress, and possibly a second check to determine pay? Or some kind of appraise system for gemstones? I guess it depends where you are mining, for that sort of thing. It might just be a random % roll based on the rock type.

Dwarf Fortress RPG anyone?
