I just spent a little while looking at the depths, thicknesses and widths of the drilling from last year. The higher grade zones of the py3, are the closest to the Fish River Fault, with the grade falling off once about 50-70 meters away, so the width is about 50 meters.
The depth of the vardy zone is often over 40 meters, while this new drill find seems about 16 meters, but depth does vary along the strike next to the FRF.

Given an average depth of say 20m times 50m in width away from FRF (though there is some mineralisation further away, but grade drops), and then 10,000m long, would give a rough 35 million tonnes of resource at a density of 3.5g/cc for the py3. The grade of this works out a a rough 4% copper equivalent, assuming the grade stays the same.

To give a rough comparison, this is about 4 times the resources of Sandfire currently, but at a slightly lower grade. This is also just for the deeper, richer PY3 that I would think will be an underground mine over that distance.
Just some quick rough calculations, and of course should the mineralisation continue for the full 30km then multiply by 3.
IMO it looks like a profitable mine to me!!
Position changed to held.
