A number of the professors we have working on green technologies are coming very close to that stage. They're at the point where they are actively seeking industry partners to get from lab scale to the pilot study. That can be challenging. Some of the mining companies—especially when profit margins are low like they are right now—are reluctant to try new techniques or mess with a working procedure to find a way to test that thing.
We're finding that some of the newer mines coming on stream, like Rainy River or Zenyatta, are very interested because they don't have a developed infrastructure in place. They're more willing to consider pilot studies.
