I have found you can dupe some of the ores via level up reloaded mod prospecting skill ore chunks as some of the chunks get turned back into ore via that mod at changes ore into a specific type instead of staying as chunks and can be further duped via a fortune pick. Example - 1 iron ore + fortune 3 pick = 4 ore chunks that turn back into ore then repeat.
