Looks like Nemaska is going to have a longer mine life than 15 years, or maybe they increase daily production.
This is being fast tracked to production so I am guessing this summer they build the mill and do some drilling and have the mill in operation late in the year (best case scenario).
This whole valley could be plastered with spodumene-bearing pegmatite, if it is we have the next Saudia Arabia style fuel supply.
