Mr. Chairman, as you know, in R and D there is a lot of uncertainty in doing the science. There is no guarantee that the science will go as we expect. We try, through science and innovation, to develop technologies while reducing the risks of technological barriers, and with the advancement in technologies in different areas of mineralogical characterization, wherein we look at field emissions spectroscopy, scanning electromicroscopy, and new state-of-the-art equipment that we have now for detection and analysis, I think we can reduce the high risk associated with one of the steps going wrong.
But again, despite all that, there is always the risk that something would not go according to plan. As we are developing the technologies and looking at the uncertainties, we'll be able to determine the success of the initiative. But certainly there is high risk associated with any type of science that we do in our laboratories.
