The short answer is that we do have quite a rich base to draw from. We use that to assess new projects as they come along--not just individual projects, but the cumulative effect of several projects in a particular area.
We play a lead role in working with provinces and territories on a number of pretty important initiatives. You mentioned the MEND project looking at the impact of acid drainage over time. We work with our provincial colleagues and use that information from one project to another, so our scientific base is always updated with the unique information of various projects. So whether it's in New Brunswick, or Alberta, or Saskatchewan, or up in the north, that repository of information is available to our colleagues and industry as far as best practices are concerned for reducing the production of acid drainage, and for the monitoring and control of it.
We also play a leadership role in the national orphaned and abandoned mines initiative. It's another example where we cooperate and collaborate with our provincial and territorial colleagues in trying to deal with some of the legacy mines. They're the abandoned mines, where companies were responsible for particular projects back in the forties or fifties, before such initiatives as putting up bonds for reclamation of mines, and so on, were put in place. The companies may have gone out of business, or whatever.
Again, there's a rich repository. We take a lead role with our colleagues in an initiative to find best practices. In fact, international communities have looked to us to replicate the MEND and NOAMI projects within their own areas.
