In my study of how much gold a player can make by soloing various lower-level instances, I decided to make a run through the Deadmines instance.  I was able to run through the entire instance in approximately 30 minutes.

Loot from mobs: 1 gold, 43 silver

Junk items sold to vendor:  26 silver, 13 copper

Common items sold at auction house:  18 gold, 52 silver, 68 copper

Uncommon items sold at auction house:  19 gold, 60 silver, 58 copper

Rare items (bind on pick-up) sold to vendor:  1 gold, 89 silver, 83 copper

Total take for Deadmines run: 41 gold, 72 silver, 22 copper

I should point out that I got extremely lucky with rare items, picking up a total of 8 rare (blue) items in this run.  However, those items are responsible for less than 2 gold of the total take.

Based on the above, my estimate is that if you ran Deadmines back to back as fast as you could, you’d take in approximately 82-83 gold per hour, based on my server’s (Fenris) pricing.
