This Minecraft 0.9.0 Infinite seed sets you on a small island in a huge body of water. Dig straight down from spawn and the fun starts. Not too far below ground you’ll fall into an abandoned mineshaft. You’re not far from gold at this point! And, there’s also iron, redstone and emeralds down the same shaft.
Explore the mineshaft a bit – you won’t find gold yet, but there is coal. Keep digging down, underneath that spawn point, and you’ll hit gold! When you dig out around the gold you will break through to another mineshaft where there is more gold! If you continue digging down, you’ll hit iron, redstone and emeralds!
