I listened closely to what you said, and you piqued my curiosity with your remarks about rare earth oxides. If I understand correctly, a process similar to the electrolysis used in aluminum production can produce permanent magnets. Here's my concern: often, when a particular country is the only country that has this kind of rare earth oxide, the material is extracted and sent to other countries for processing.
A while ago, a witness recommended setting up a critical minerals reserve so that the processing part of the supply chain could happen here in Quebec or in Canada.
I'd like you to comment on the specific potential of rare earth oxides and the possibility of producing permanent magnets.
