From their 2008 rights issue offer document -

"Minara sells all of the nickel and cobalt that it produces under a long term offtake agreement with Glencore. Under this agreement, the Company receives a provisional payment calculated at the spot price for nickel and cobalt at the date of delivery, with a final balancing payment made either to or by Minara based on the average spot price for nickel during the third month following delivery and the average spot price for cobalt during the month following delivery."

I wonder how often they deliver to Glencore. It works on average price though, so I guess it doesn't matter too much.
