How miners grade mineral discoveries, page-2

Keep in mind that there are no producing cobalt mines, sulphide or laterite, that has a resource average of more than 0.5-0.6 cobalt...Most of the DRC cobalt being mined averages about 0.55....eCobalt's Idaho resource is 0.54....All of the cobalt juniors listed on the ASX that have either a SS, PFS or DFS/BFS have cobalt resource averages of 0.06-0.14...

Yes, there may be a meter or two or three of 1% or higher cobalt but the average for the entire resource is much less...
