Finding the necessary ores...

There's little to no information on where they can be found so where have you guys been finding them? Here's what I gathered so far.... Gold - spawns at level 30 and below almost always hidden in copper veins. Titanium - Spawns around the same area but is usually not surrounded by copper Diamond - Spawns at level 10 and below Low Endurium Ore - Spawns in huge clumps on the floating islands (look for the green glow in the sky) High Endurium Ore- Almost always spawns on bedrock and is sometimes found at level 5 and below. Are there better ways to finding these ores? Does distance away from the spawn affect how often you find them at all?
