The qualification for the flow-through tax credit is fairly narrow. It is essentially grassroots exploration, so it doesn't extend to predevelopment, development, or construction activities. The point Brian was making was that these specialty minerals are quite different from the run-of-the-mill base and precious metals. Often the metallurgy and the processing are complex. It's a research and development exercise to find the best way to extract these minerals and to develop commercial processes. Things like taking a large bulk sample, doing a pilot plant test of the technology, and then doing additional testing to scale it up and demonstrate that it is commercial—none of that is currently covered by the flow-through share program.
What we are basically suggesting is for the clean tech minerals. We can define what the minerals are and what specific activities relating to their upgrading and commercialization are included. We're not talking about hundreds of millions or billions of dollars here. In our case, it would probably be a couple of million in terms of bulk sampling and so on. We have a very promising purification technology, which relates to the manufacture of anode material for lithium-ion batteries, and also bipolar plates for fuel cells. We need to do a pilot plant test of that process. We are entirely dependent on the capital markets for that. It's not flow-through eligible. Right now, the capital markets are not great, so we're kind of stalled, which is unfortunate, obviously.
