Occasionally, this amount is enough to keep a mining crew busy for a lifetime or more; much more frequently, however, the mine plays out after a certain period of time. To determine how long before a mine’s wealth is depleted, the DM should secretly roll d100 at the start of the mining operation. The resulting number equals the number of man-weeks that the mine can be worked before depletion. If the resulting number was  doubles (e.g., 11, 22, 33, etc.), however, the mine has a much longer duration. Roll d100 again, and this time read the result as the number of man-months that the mine lasts, adding this figure to the number of weeks already determined.If this second d100 roll also yields doubles, roll d100 a third time, and this time read the result as the number of man-years before the mine is depleted. Further doubles rolls are also rerolled to provide an additional number of years, until a d100 roll is made without a doubles result.[/spoiler]It also went into value, smelting, mining hazards, the claim, quality of the mine products, shoring up tunnels, mining rates, and more.</blockquote>
