I wanted to follow through with a comment from Vic and also look at your operations, because we've heard from Goldcorp, for example, that they're moving forward to an all-battery mine. There are batteries today in heavy equipment. We have a company in Sudbury selling batteries for heavy equipment in Russia and all over the world. There are alternatives today that are quickly moving forward. I How can we capitalize on that?
Vic, you talked about the need for more R and D and how to utilize some of that R and D, which you already have developed, to commercialize. Can you expand on that?
