Just to be clear, you put it on a normal patch of copper, inserted the quality modules, and it doesn't produce any quality ore?
In 100 ores, it should make about 4.5 pieces of uncommon or above ores.
Hovering over the miner should show various ratios of quality ore as "available ores". Does it not show this?
