Ann: Upgrade of Resource & Scoping Study, page-33

Some of you need to go to the country for a drive to get perspective.
This is 1.9mt over 824000 sq metres.
That's 82.4 hectares or 200 acres.
But this was spread over 2sqkm or 2mill sq metres.
That's 500 acres.
Doubt they will ever achieve 800000 ton/year.
It's not economic going down only 1.4m spread over more than 500 acres.
2sq km is about 4000 x 500sqm house blocks.

800000 t/year is 300000 sqm x 1.4 x 1.9 density.
600 house blocks per year if it was all uniform and flat.
Good luck.
