from the uranium threads in relation to what grades of uranium are considered.....MXR cut off is 100ppm with a grade of 180ppm which on the figures below put the resource in the mid to good grades and cut off.

These are the basic numbers that I tend to look at when considering a stake in a Uranium Spec.

Hope this is of some assistance:
____________________________________________________

Low U3O8 Grade 0.01% (100ppm) to 0.03% (300ppm)

Mid U3O8 Grade 0.05% (500ppm) to 0.08% (800ppm)

High U3O8 Grade 0.10% (1000ppm) to 0.20% (2000ppm)+

As well as Grades, one must also take into account the Cut-off used by the particular Company, in calculating the Jorc. Resource, & equal importance is the depth location of Resource & Geology of region.

Cut-offs
Poor 50ppm
Fair/Average 100ppm
Good 150ppm
V/Good 200ppm
Excellent if above 300ppm
Exceptional above 600ppm"
