I'll take the first shot at that.
I think if we talk to anybody in exploration, the best place to find a new mine is next to an old mine. There were some incentives in place that would help to offset some of the expenses for deep drilling. A lot of the reserves are now more and more at depth, and it becomes uneconomic at a certain point to drill.
In mining, we use the term “brownfield”, which means an existing mine site. Perhaps looking at developing some mechanisms that.... Maybe it's through a regulatory review, that if it's within a certain area, you don't need to undergo a five-year-long assessment process. Or maybe it's a financial incentive that looks at incenting brownfield exploration. That might be one way to facilitate more of that cluster approach that you're speaking about.
