Yes. Thank you very much, Mr. Tan, for the question.
There are other examples that I would specifically like to speak to, and we're seeing a collaboration of industry, industry associations, and the Geological Survey, as well as the Ministry of the Environment.
With respect to looking at the largest footprint on most mining sites, whether it's a legacy site or an active mine, there is often a tailings and polishing pond area. There's opportunity to recycle water, but it is an opportunity that is often embedded within the environmental assessment anyway with their permit to mine. That's an ongoing challenge in being able to reuse that water. The bulk of mines are reusing the vast majority of the water over and over, and that's really an ongoing piece.
There's also an opportunity, I think, at Lakehead University with their Centre of Excellence for Sustainable Mining. They're doing a lot of work with Barrick. The Williams Mine at Hemlo is Barrick's only producer in Canada, as the world's largest gold company.
There's a lot of work regarding remediation with indigenous people around wild rice and the impact of these existing tailings. The mine has been in production, as many of you know, since about 1984, and the life of Williams Mine will likely continue for another five years. That's an ongoing piece. That's very much imbedded within the impact benefit agreement. We work with communities like Heron Bay and Pik Mobert, in particular, as they work arm in arm to look at opportunities around those particular tailings ponds and repurposing them, eventually.
