Thank you, Mr. Acting Chair. You're doing a great job.
I have a question for either Dr. Kasperski or Dr. Hamza.
I found your presentations very interesting. You can correct me if I'm following it wrong, but as I understand it, particularly from your handout, page 7, you're saying that the reason we have the system we have now for dealing with the tailings and tailings ponds is because that's the science that the consortium put together and that's what they decided to proceed with.
How long has it been that we've had better technologies but they're not being required to be taken up by the companies?
