I believe, if we can make the mine in less than four years, that would make sense. The transformation is about two years for existing materials.
I can give one example. If we mine graphite, it could take less than four years. If we have the raw material—the graphite—it would take one and a half to two years to bring graphite to the market, with the transformation, purification and so on. If you are going to develop new materials with the technology that's here, it usually takes 10 years. Then, if we have the programs supporting EI, we could shorten it to five years.
It could be four years, one and a half to two years, and then less than five years for new materials.
