Mining is primarily done in caves. Activate a [[Pickaxe]] and right-click a rocktile, then select Mining -> Mine. Every mining action on a regular rock tile gives a rock shard. +/- 25 mining actions creates a cave entrance. Within a cave, +/- 50 mining actions are required to let a cave wall collapsecontinue the tunnel.

To find specific ores, you should [[Prospecting | prospect]] on the surface. Prospecting in the cave itself will only tell you the quality of the tile(assuming you have at least 20 prospecting skill).
