Ann: C29 Acquires Transformative High-Grade Uranium Project, page-60

Any developer has to make the economic case.
Size, grade, scale of operation, and capex required to develop V payback economics..

Whatever it takes to get lbs out of the ground. Higher grade = less consumables = more profitable per lb.

Whatever it is, it is all about how many years will the cow milk for, after i have paid back the initial capital on the cow, and what is that initial payback period.

PEN is another stock that comes to mind, which utilities ISL in USA.

BMN and DYL are similar and adjacent to PDNs operations in Namibia, same sort of paleochannel (ancient old river beds enriched ) deposits.
