− | When the wall-part is removed from a stone tile, there is a 25% chance that a single [[stone]] (also known as a boulder) will be left behind. Minerals which are found in [[vein]]s have a 33% chance of leaving ore, and minerals found in [[vein|small clusters]] (or individual tiles) have a 100% chance of leaving a stone or rough gem behind. Finally, any "deep" material (i.e. [[adamantine]] or [[slade]]) has a 100% chance of leaving a usable stone (though the latter is normally undiggable).

Carving a channel down or ramp up needs special care to provide the full 25%/33%/100% mineral production: in the case that both the bottom tile (where the new ramp up is) and the top tile (new open-space above the newly carved ramp) are both dug out together as part of the same designation, there is only a single chance of mineral production, even though two tiles had their wall-part removed, effectively halving the mineral production chance to 12.5%/16.5%/50% in that case. But if special care is taken to ensure the top open-space tile is dug out first before carving the ramp below it, the full chance from both tiles can be achieved. | Carving a channel down or ramp up needs special care to provide the full 25%/33%/100% mineral production: in the case that both the bottom tile (where the new ramp up is) and the top tile (new open-space above the newly carved ramp) are both dug out together as part of the same designation, there is only a single chance of mineral production, even though two tiles had their wall-part removed, effectively halving the mineral production chance to 12.5%/16.5%/50% in that case.
