We're in the very early stages, frankly.
Indium often occurs with zinc, and that's why it's recovered from the zinc ponds at the Trail smelter, but it occurs at higher concentrations in other types of mineral deposits. One of them is tin greisen, of which we have a classic example in southwestern Nova Scotia, where it is very highly enriched. There's also zinc there, but these elements can be recovered from the same resource.
As I mentioned earlier, there's also all sorts of lithium in the country rocks to the tin mineralization there, and similar resources in Europe—in Cornwall, England and in the Czech Republic—are now being looked at as an opportunity to recover lithium, as well as indium and tin.
Tin is an electronic metal now, too. Most people think of tin as in tin cans, but no, it's a tech metal. It's used in renewable energy applications, too, and there's no supply chain on it in Canada or North America.
