Mr. Chairman, the further you go in the separation process, the more value is added to the product. So it's advantageous for companies to develop grinding, milling, and processing processes that go as far as possible and come as close as possible to the pure oxides, which are the materials that are needed by the manufacturing companies. Depending on the availability of technological facilities, the ease of constructing that equipment and those facilities on site, it is possible that ore could leave at different stages, depending on the company and depending on the ore type as well. It's a very difficult question to answer. It's very ore-specific.
