Talk:Hardmode Ores/@comment-75.84.220.225-20130531001526

I have not got to hardmore yet and I found this page useful.

What I am scared of is when i go into hardmode does my gold ore, silver ore, iron ore, copper ore disappear or get replaced by the new ores? Where exactly does this ore spawn? And is it possible to have all 3 cobalt, mythril, and adamantite ores on your world at the same time?
