“Coaster” Brook Trout
Host rock: Peridotite
Minerals: 3.57% Ni 0.28 gpt Au
2.91 % Cu 0.73 gpt Pt
0.10% Co 0.47 gpt Pd
Expected yield: 300,000,000 lbs of Ni
250,000,000 lbs of Cu

Magma acquires sulfur from surrounding rock on the way toward the surface
Depletion of metals
Metals and sulfur settle out and form a sulfide deposit
Metals like to bond to liquid sulfur……..
Primary ore minerals:
Pentlandite: Ni6Fe3S8
Chalcopyrite: CuFeS2
