So looking at the 50ktpa train,

On a quick check below, you get within rounding of the numbers given. 78.4kt of ore becomes 66.6kt of MSM across two different grades. MSM as per above is also a mid-30% product so the 85% recovery factor probably reflects both loss and concentration factors. Taking the numbers quoted and multiplying them out gives $74.3m of margin and the quoted figure was $73m. This is within the range of rounding.


If this 78.4kt of ore was shipped at the Dec 2020 price estimate of US$4.39/t it would have generated about US$11m in revenue. If put through the planned process, this increases to US$112m of revenue. It will be interesting to see the markets reaction today.

From the link below the mass composition of MnSo4 is :Mn 36.38%; O 42.38%; S 21.24%
