Ann: High Grade Continues 5.7km West of Resource, page-8

This is a potentially bonkers size orebody here.




Have a look at this cross section and imagine two stacked ribbons of ore alongside the Fish River Fault with Lead+Zinc dominant ore (blue trace) stacked on top of a higher grade Copper Cobolt ore lens (red trace), on this section the upper Lead Zinc Lens looks thicker and bigger but on other sections it has been the other way around so allow for some variation in the two lens dimensions and grades.

So for the strike length of 5.5km, looks like true widths of 15-20m (although there will be a gradational decrease in ore grade further from the Fish River Fault) you can do a very rough volume  estimation and come to a volume of something like 8 to 9 million cubic metres for each of the two ore lenses, then apply a (conservative) ore density of say 2.85 tonnes per cubic metre and using some averages of grades of pierce points announced from the 5.5km to come up with figures such as:

Lead Zinc Lens =  23.5  Million tonnes at say 7.2% Pb, 2.9% Zn and 84g/T Ag
Copper Lens =  26.2 Million tonnes at say 3.0% Cu and 54g/T Ag

And thats without counting any of the better drilled Vardy and Marley Zones.

Except for the Vardy and Marley zones that may be open pittable - a lot of this 5.5km is probably going to be underground mining rather than open pit due to the depth and stripping ratios so based on underground ore production rates of say 1-3 million tonnes per year this is a 10-25 year mine life proposition.
