I used most of an adventure called Base of Operations from the Wizards website in one of my campaigns. The module is set around a small castle called Brightstone Keep, so named for the mine in the hills about 200 yards to it's north. The mine is explained in the write up as 'still producing', but there are no specifics as to how much it actually puts out.
The party has hired 8 dwarves that were captive in the keep to rebuild the keep and mine the area. Does anyone know how many gems a mine puts out in a week, month, or year? I know I can adjudicate this, but I don't even know where to begin.
Thank you, in advance, for any input you can offer.cross posted to dungeonmasters
