There seems to be a fundamental misunderstanding. I'm assuming the price obtained is based on:

"Nickel Price

Subject to the terms of the Hedging Agreement, the price payable by Hartree for nickel concentrate contained in the Product shall be calculated by reference to the arithmetic mean of the settlement price for “Nickel Cash LME Daily Official $ per tonne”, as published in the Metal Bulletin in US$, over the applicable quotational period (Nickel Reference Price)."

and that "the terms of the Hedging Agreement" mentioned relate to concentrate quality aspects, penalties, how transport costs are dealt with, perhaps etc. What Hartree actually sells the product for is their business.
