'Maiden Indicated and Inferred Mineral Resource of 112.4 million tonnes, grading 0.11% cobalt, 0.41% copper and 0.43% zinc, at a cut-off grade of 0.06% cobalt'

Seems like anything over 0.1 per cent is good especially if there are other metals. Copper is not bad in this case. The company also said it exceeded their expectations.

Cobalt Blue has a lower grade with nothing else. But I think it is overvalued anyway.
