Aside from the awkward May 1 PR, I just had a look and nickel is already up from $ 6 early this year to almost $ 10. Up a buck in the last five trading days.
The PFS will use long term industry price estimates, but this jump based on supply concerns might aslo influence the outlook of nickel positively for the long term estimates.. just in time for the PFS.
Twin Metals nickel revenue as % of total mining revenue is just a bit over 30% in my model. Copper is half the revenue, PGM the remainder.
