Here is a list of all the Ores found in each zone to help you collect all 500 items since rank 1-5 of each count as different items in your collection.
PS. you might find ones not listed, but for the sake of finding all or farming a certain type this was faster and easier.
PSS. you can save after a fight in a different map, then travel to the map the ore is on to roll the RNG, loot the deposits and if you don't get what you're looking for, reload your save and travel to the map again, the RNG will be rerolled upon entering the map so you'll get different ranks and ores each time. From what I can figure out is the RNG is manipulated when doing a fight off map, and then deposits are locked in when loading into the map.
