We are not at the moment because we're finding a lot of materials that are very important for the future economy and to support climate change within our existing streams, so we're focusing there first.
One of the big challenges is that, if you go and look for deposits of rare earths, by their very nature they come in very small concentrations, so you end up having to deal with.... You then have to present yourselves with the environmental issue of what to do with all of the waste you generate.
That's why, from our perspective, we're looking at how we keep our footprint very small but still provide these critical minerals and metals for the future.
