And here's a key quote relevant to MEI's cobalt:

"While anything less than 1 per cent cobalt (Co) is low-grade, the high price of the battery metal at the moment is making large deposits with grades of as low as 0.1 per cent economic.
Grades of 0.3 per cent are currently considered very good with scale.
In general though, less than 1 per cent is low grade and over 2 per cent is high grade."
