For Lovers of Nickel, page-103

The BS complex JORC Reserves* are 3.3kt Ni for SS (5.79% grade) and 21.5kt Ni for BS open pit (0.63% grade). Combined they total 24.8kt Ni with a weighted average grade of only 0.72%. According to the BS complex FS this is only enough to run the BS processing plant at ~50% capacity (i.e. a little under, actually, but let's be generous) for an initial total of 3 years.

There's no way that SS with its paltry 3.3kt contained Ni is going to be anything more than a blending resource that helps up the average of production from the BS pit (where the real tonnage is). Any hopes of starting SS in isolation (and processing them through the BS concentrator) are outside the realm of reality.

How come they can restart and make this work but not POS?!

Because at 2.7-2.8% (slide on p.10) Venus' average Ni grades are materially higher than our weighted average SS/BS grade of 0.72%. There are also much better economies of scale of with a much larger ore body.

(*Our SS/BS Resources averages are also similar-to-slightly worse.)
