These are all google search results. I claim no expertise only great interest! Let me ad these to the pyrrohotite / pyrite debate:

Nickle: The metal is obtained commercially from petlandite (nickel sufide) and pyrrohotite (magnetic pyrites) of the Sudbury region of Ontario, Canada. This district produces about half of the nickel in the world.

Nickel mineralization is associated with pyrrhotite and pentlandite, found as widely spread disseminations within the serpentinite units and the major metasediment unit. Microscopic grains of pentlandite have been identified as intergrowths with pyrrhotite and pyrite. There is no correlation between pyrite and nickel mineralization.

Maybe what they see is actually Bravoite!

Bravoite is a nickel-cobalt bearing variety of pyrite, with >50% substitution of Ni2+ for Fe2+ within pyrite. Bravoite is not a formally recognised mineral.

And then as JD pointed out, pyrite is also noted in NOT's findings. Let's hope these assays are more like NOT's then NOT!
