how big is rossing south project?, page-4

Zones 3+ has to be guesswork at this stage. Here is one example working:

Zones 1+2: 250-280 million* lbs over 6 km
Zones 3+: A further 9 km

(*see posting: http://www.hotcopper.com.au/post_threadview.asp?fid=1&tid=906765#4104464)

If the size of the uranium continues in the same way as Zone 1+2, simple extrapolation gives a total of between 375-420 for Zones 3+. Add to this the 25 million lbs for Ida Dome, we have a total of:

Rossing South total: 650-725 million lb

This is subject to the remaining zones being the same as Zones 1+2. They may be less, they may be a lot less, or even zero; conversely they may be greater than Zones 1+2 as well.

It's only a guess, and could be significantly out. That's all we know at this stage.
