Correct. TRO is the acronym for tailings reduction operations technology. The TRO technology is the treatment of the tailings to remove water at an accelerated rate. This will allow us to return dry tailings to the mine, versus having to store them in tailings ponds for long periods of time. It takes a process that would normally take 40 to 50 years to consolidate these tailings down to a very short timeframe. During the summer months we can dewater these tailings in days instead of decades.
It is a major breakthrough. The $1.2 billion I mentioned is the capital that's being invested to deploy that technology at commercial scale. That's occurring as we speak, which is a significant shift in our mining technology and overall approach.
