Thank you very much for the question.
Just to frame an example here, I would suggest—and I track this on a regular basis, and picking up on Iain's point—the all-in sustaining cost that day for production at that particular mine, in U.S. dollars, ranged from roughly $700 to about $1,180 an ounce cost on the footprint of any given operation. That's for some of the largest to the very smallest operations in northwestern Ontario. In some cases there's very little margin, so if that additional cost is there, you may be generating red ink, and a mine general manager or a mine president each day monitors that exchange rate, that cost all-in sustaining, and the price of gold today as they plan forward. So that could be putting some projects on very tenuous ground.
I appreciate your comment about electricity prices in Ontario. The NIER program does help offset some of that. Some of the companies have had to go to other incentive programs like the IEI, which has helped a little bit as well. Any break helps. But, again, there's concern about carbon tax and cap and trade as this moves forward. Is it likely going to add to that additional cost and the bottom line, that all-in sustaining cost that morning when that mine continues on its path? It is a concern.
