Tested on Minecraft 1.5.2
This Minecraft Seed spawns you in a plains biome with a half dozen cows nearby. Also, next to the spawn point is a decent cave system which will make gathering some ores very easy at the start. So grab some coal and iron ores and lets move on. (X: 11, Z: 133 for a dozen surface coal ores…torch time!)
[showmyads]There is a small NPC town at X: 83 Z: -154. It comes complete with a blacksmith and several farm animals (cows, sheep) nearby. It is in the plains with a jungle biome near. There is a ravine really close to here at X: -15 Z: -232. In a cave near the bottom of the crevice is an abandoned mineshaft and in there are several surface diamonds at X: -1 Y: 14 Z: -165. If you keep exploring you will find 2 more diamonds at X: 26 Y: 13 Z: -165
There is an absolutely ridiculous ravine that you MUST go check out. Its double wide with a lava floor. Surface diamonds all over the place and an abandoned mineshaft. X: -683 Y: 17 Z: -199. There is a stronghold connected to the abandoned mineshaft, if you have the coordinates for it leave them in the comments. Check out the video:
There is also a Jungle Temple (X: 878 Y: 78 Z: -384) and Desert Temple.
