TAJ said that they suspected He3 may be present at Topaz, presumably because of the geology, which leads me to speculate that the design, and timing, of the process plant will take account of the He3 and He4 separation. Although TAJ said the focus was on the He4, I suspect they are underplaying the He3 component; the fact that Peter Barry was involved suggests the He3 is important.
Peter Barry did refer to methods of He3 and He4 separation; whilst it can be done, the question for me is can it be done economically at scale. I would be surprised if Chart are not working on this aspect.
Another point to consider is transportation: TAJ said that He4 could be shipped by rail, but they would use road transport for He3, presumably because of the smaller quantities involved.
Hopefully, the next 4 - 6 months will produce plenty of news about Topaz culminating in updated resource figures for He3 and He4.
