I can answer like this. What we know we don't have is the type of mineral deposits that China has. We know that because these types of deposits develop only in subtropic areas around the world. I know that there are European companies looking at identifying deposits around the world that are similar to China's. They're looking in Africa, for example, or other equatorial countries.
So we don't have these easy-to-take-out rare earths. This we know.
