Just double the size of the mines and give people a cut of the proceeds based on how much of the mining they did. That should do it.

A drasine in the mines would make sense...maybe even a mine cart, if someone can do the graphics better than I...like, replace that tiny yellowish room in the upper left with the minecart and track and a little cave that the player can't go into (have some weak excuse like it seems to drop off, not safe, the miner stops them), and they can jump in the cart for a ride to Mine Room B, which only goes once a minute round trip - 15 seconds at A, 15 seconds in transit, 15 seconds at B, 15 seconds back
