of Nautilus have worked closely together with world experts to design the project in such a way so as to ensure that any extraction impacts are kept below 1300m water depth, including taking into account environmental conditions such as currents. We must remember that fish such as tuna live in the light and oxygen zone where their food is -- i.e. the top 200m of the surface of the sea. So, there is a "buffer" which is over a kilometre long between the fish and any extraction impact. One of the design achievements involved working with world-class offshore experts to design a pipe and pumping system which is fully enclosed. What this means is that the copper-, gold- and silver- rich material is taken from the seafloor to the surface vessel without ever coming into contact with the seawater above the Solwara 1 site. This was not the cheapest solution, but it is the most environmentally and socially responsible solution to ensure fish stocks and people's livelihoods will not be impacted. Nautilus has made other commitments too: unlike other projects, there will be no blasting at Solwara 1. We have committed to using biodegradable fluids and oils in all equipment operated in the sea and no hazardous chemicals or tailings will be discharged to the sea. As an aside, another aspect of the project that excites me is that we are working on a processing solution that will mean there are no tailings in PNG from our operations. To me
