There are different standards that we use. Some of these standards have to do with ICMM. Some of them have to do with EITI, which I just mentioned. Some of them have to do with the different type of processes we are actually going to be using at the mining operation.
For instance, if there is the use of cyanide in terms of a heap leach operation, we make sure that all of our operations are certified by the International Cyanide Management Code, which is a certification that is audited by a third party. It's an extremely rigorous process to obtain your certification, but it basically has to do with how you manage the product of cyanide in your country and how you use it in your process.
Those are some of the examples of some of the initiatives or regulations or associations that we belong to that have a long set of standards.
