Just doing a bit of hot copper maths.
1 ppm = 1g/T
10ppm=10g/T
100ppm= 100g/T
1000ppm=1Kg/T
Gold @$1720/oz Au = 60million bucks au/ T
Cobalt = $50au/lb or $117k au /T
Gold is 512 x More profitable to Mine than cobalt.
Gold is mined economically between 1-2 grams per tonne Ref $BLK but thats not without it problems
A better example; And I keep bringing it up so often that I should probably just buy shares in it myself but. PNR Pantoto mines gold at at head grade of 7g/t which roughly converted to cobalt 7 x 512 is
about 3500 ppm which it .35% cobalt //
anyway very ropey numbers from my hungover brain
Just doing a bit of hot copper maths. 1 ppm = 1g/T 10ppm=10g/T...
