This is probably some type of bug or glitch. Remember Chlorophyte spawns in the jungle and can only be mined with a high level pickaxe so perhaps you've been missing those. As for the other ores im not quite sure, you may need to wait for the next update for some type of patch. Trust me you are not alone on this :)
