It was mining technology that built the Canadian space arm. That's one tangible example. We have companies that are looking to do the first totally electric underground mine in North America. We have companies in the Northwest Territories that have facilitated a composting system that reduces power on site but also leaves biomass for reclamation purposes in a terrain where there is very limited overgrowth. The downstream supply chain effects for reduced emissions, reduced transportation costs, reduced land movement have an accumulatively positive effect. That's Dominion Diamond, by the way.
I think Mr. Easter is signalling that I may be at the end of my time, but I really appreciate the question. Innovation is key. When you are taking a percentage out of rock that in some cases is less than half a percent, the amount of energy that's required, the amount of innovation and intuition to be able to do that when in certain cases it's upwards of two kilometres underground, is an ongoing constant engagement of reducing costs, managing project deliverables in a multi-faceted shifting environment.
