EMC they are actually very decent Rubidium Grades.
Seeing it's worth $1000 000 per Tonne,
It doesn't require much,
To make it Viable....
So 0.26% Rubidium,
Is 2600 Grams per Tonne, worth $381 420 +
Compare that to the likes of Coal, Iron Ore and a 1gt Gold Mine,
Where each Tonne is only worth $100 - $140 per Tonne of Material,
And one can start to see why.
Rubidium at 0.26% per Tonne is still worth $381 420 per tonne of material,
Making it far higher value,
as in 3814 x what operational Gold, Coal and Iron Ore Mines,
Are worth Per Tonne....
