Formation and Characteristics of Sulfide Deposits in Coaster Brook Trout Site

Coaster Brook Trout hosts a significant sulfide deposit within peridotite rock, characterized by diverse minerals and promising expected yields. The deposit comprises 3.57% Nickel (Ni), 0.28 grams per ton (gpt) of Gold (Au), 0.73 gpt of Copper (Cu), 0.10% Platinum (Pt), and 0.47 gpt of Cobalt (Co), alongside Palladium (Pd). Metals such as Copper and Nickel bond with sulfur to form essential sulfide minerals, primarily pentlandite and chalcopyrite. This process plays a crucial role in the formation of valuable mineral resources in the area.

  1. “Coaster” Brook Trout

  2. 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

  3. Depletion of metals Metals and sulfur settle out and form a sulfide deposit Cu S Ni Metals like to bond to liquid sulfur…….. Pd S S Co Pt Magma acquires sulfur from surrounding rock on the way toward the surface Cu Ni Pd Co Pt How do sulfide deposits form?

  4. Primary ore minerals: Pentlandite: Ni6Fe3S8 Chalcopyrite: CuFeS2
