Mr. Ronan Boyle:

I will take the last part of the Deputy's question and I will let Mr. Earls address the first part. The system is driven by a compressor, which is a specific model in terms of the volume and frequency of air that is used, and it is linked to a rotary valve that drives the air into the tank into each location for a specific volume of air for a specific amount of time. Those are the mechanics of the slurry technology system.
