Thank you, Mr. Vice-Chair.
I thank our witnesses for appearing today.
Let me start with Dr. Schindler.
Looking at your results with respect to heavy metals, for example, how do they compare with other types of minings and tailings? Have you done any comparative work, or can you point us to some comparative work between what's going on in this particular watershed and what's going on in other watersheds or in different mining operations? Can you give a sense of some of the differences? Is this worse, better, or the same as what you'd expect with other mining operations? Can you give us some sort of qualitative or quantitative indication on that?
