Yes. What we intend to do, on the tailings stream at the end of the pipe, between the plant and the tailings pond, is set up an off-line facility that would take in that tailings stream. It's very hot. It's about 75°C, 80°C. Some streams are 50°C to 60°C. There's a lot of heat there that we don't require.
In striving to clean up the tailings ponds that exist, we have to raise that temperature. So why not use this excess heat from the tailings stream and blend it with tailings pond sludge to reach our temperature, so we don't add any energy into the system, we're not burning fuel and generating CO2 emissions and so on, and use that in our process starting at 40°C? When the water comes out of our process, it's at about 38°C, so it's quite warm and it's suitable to be put back into the extraction process up front.
