Mr. Chairman, on the question about the study that has been conducted, I'm not aware of that study.
But in the area of environmental science, the project will be looking after the environmental impact of rare earths in the environment. It's a study that began a few months ago. To date, we don't have enough data to make any further comments. We'll be happy to share at one point in time, once we have some, the data available on the environmental impact of rare earths.
