Schall Alien Loot combined with this mod makes it possible to acquire high-quality ores from the start of the game, but since no quality tiers have been unlocked, these ores are unusable. Unlocking uncommon and rare qualities from the beginning of the game will allow these quality ores to be used.

the latest release allows you to disable the enemies from spawning with quality via a tick box in startup mod settings that will address this if you wish to tune monster difficulty / rewards with other mods.

Outside of that you would need to take it up with Schall's Alien loot owner which is creating the loot to ensure the quality is "appropriate" that drops.
