I haven´t looked too hard at the SH comparison of Tyhee with Metanor, but two items immediately struck me as being either incorrect or misleading:

Tyhee has 1.9Moz M&I, not 2.1Moz as stated

Tyhee´s underground mines are calculated to have average grades greater than 5 gpt.

Not mentioned is Tyhee´s mill is proposed to be 3000 tpd, Metanor´s is hoping to get to 1,200 tpd.
