"- Further drilling at Eagle Two (Anomaly AT2) continues to trace a Shear Hosted Sulphide ("SHS") zone containing bands of massive sulphide mineralization with visible copper-nickel minerals from the Precambrian rock surface (starting at 10 meters below surface) to 190 meters below surface where the approximately up to 21 meters thick, 75 meters long oval-shaped mineralized zone is within 30 meters of the favourable underlying granodiorite intrusive contact. - Massive Chromite beds up to 48.4 meters in core thickness at AT2 have been encountered in the near vertical dipping, wide peridodite sill occupying the non-conformity between the underlying granodiorite intrusive to the north and overlying Precambrian volcanic stratigraphy to the south." The Eagle 2 description in the NR starts to draw some similarities in my mind to the geological settings of a world class PGM mining district - The Stillwater Complex in Montana. The Stillwater Complex, which hosts two of the largest PGM producing mines in NA, is a Layered Igneous Complex which is composed of a succession of ultramafic to mafic rocks derived from a large complex magma body. The molten mass was sufficiently large and fluid to allow its chemical constituents to crystallize slowly and sequentially, with the heavier mafic base-metal minerals settling more rapidly toward the base of the cooling complex, and PGM-enriched host rock representing one layered sequence. The layered, mineralized body was pushed by a later ground movement to have turned about 70 degrees to become The Stillwater Complex. Bushveld, the world's biggest PGM producer, with its Bushveld Complex, has a similar geological setting. The geological model of The Stillwater Complex was a brainchild of the famed geophysicist Terry Crebs, who also initiated the correct theory that helped the early development of Voisey's Bay discovery (pp. 108-109, The Big Score) This, of course is purely my imagination at this point. ~p |
