If you go to SEDAR and read the scoping study by Scott Wilson RPA, you will see that the plan is to produce about 30,000 tonnes of metal (copper plus nickel plus cobalt) and tha capital cost is about $1.3 billion for a plant treating 6000 tpd of ore.

Now, you can play about with the figures included in this report to make your own judgments, as I think that most of us on this forum do - make your own predictions on metal prices, sulphuric acid, iron ore, etc. and see where it takes you.

Personally, I think that if they can sell the acid in Nunavut, as is presumably being suggested by the references to uranium, then this project must be a winner.
