Mr. Chairman, the process for the milling and hydrometallurgy separation and leaching for all rare earth elements is the same. If the technologies that we are developing are able to resolve this separation issue between the different elements, the technology would be applicable to all the elements we have. The five most critical ones, which we talked about earlier, are the five heavy rare earth elements gadolinium, dysprosium, terbium, europium, and yttrium. These are the five heavy rare earth elements that we are focusing our research on.
This would also be applicable to the suite of other rare earth elements that we are considering, but for now we're focusing on the heavy ones.
