re: 40 g/t of u - is this economic?- reeefton foll Yes the surface expression is probably a much lower grade than the source concentrations - thanks for those who pointed this out. Thanks Sturds witrh the Haskeen grade info (requoted here):
"1978 Hakskeen reserves
The proven ore reserves are 361 250t of U308 at
331 g/t (johnson 1978)"
So Haskeen is a third of a kilogram per tonne of U3O8 but with a comparitavely large tonnage of contained metal. From the web I got that most Australian economic resources are over 1Kg/tonne :
Name State Class Commodity Average Grade Grade Unit Total Resource Resource Unit Contained Commodity Commodity Unit Latitude Longitude Operating Status
Angela NT MRS U3O8 1.3 Kg/t 3.62 Mt 3985.606 t -23.92 133.92 mineral deposit
Bigrlyi NT MRS U3O8 3.7 Kg/t 0.59 Mt 1849.487 t -22.22 131.03 mineral deposit
Jabiluka NT MRS U3O8 6.7 Kg/t 6.8 Mt 38634.88 t -12.499 132.914 mineral deposit
Olympic Dam SA MRS U3O8 0.5 Kg/t 650 Mt 275600 t -30.44 136.889 operating mine
Ranger NT MRS U3O8 1.9 Kg/t 0.8 Mt 1288.96 t -12.673 132.918 operating mine
Valhalla QLD MRS U3O8 1.5 Kg/t 4.02 Mt 5108.352 t -20.389 139.369 mineral deposit
Yeelirrie WA MRS U3O8 1.4 Kg/t 33.81 Mt 41258.592 t -27.182 119.904 mineral deposit
Qlympic Dam is only half a kilogram per tonne but it has over 1% copper in the ore.
