Minecraft wiki entry for Mining, associated text: This is variation of the spiral which consists of a spiral of 5×5 rooms leading down. Simply dig a straight staircase down for a short while, then dig out a 5×5 room and add a torch or two. Turn right or left, and dig another staircase for a short while, and dig out another 5×5 room, add a torch, and so on. Remember to always turn the same way. This method allows players to find a large number of ores. If they hit bedrock, don't worry, go back up to the first room and turn the opposite direction this time. It is very helpful if players want to avoid lava and such. It also has the tendency to open up underground caves, which are always well-stocked with ores and gems. Just remember to be careful of monsters, so always bring a sword when using this method.
