ORE MICROSCOPY STUDY RESULTS
FERGUSON LAKE, NUNAVUT, CANADA
Starfield Resources Inc. (“Starfield”) has received results from an ore microscopy study performed on three samples from the Ferguson Lake project's Nickel-Copper-Cobalt-Platinum-Palladium massive sulphide deposit. These samples were taken from core obtained during Starfield's Spring, 1999 drill program. The samples were prepared as polished thin sections which were then analyzed by microscopic and scanning electron microprobe techniques at the Exploration Research Laboratory of Cominco Ltd.
The study indicates that the Platinum-Palladium (“PGM”), Nickel and Cobalt metals are contained in three discreet minerals (Moncheite, Pentlandite and Gersdorfite, respectively). Copper is sourced in chalcopyrite, a copper-bearing sulphide. The Nickel-bearing mineral pentlandite is present as laths and grains developed at pyrrohotite grain boundaries. Moncheite (a Palladium rich PGM mineral) is observed as grains either in pyrrhotite or abutting magnetite grains. Gersdorffite, a cobalt sulphide mineral, is apparently present as fine grains disseminated in pyrrhotite.
The fact that the metals to be recovered have their own discrete mineralogy should bode well for ease of separation and hence higher than average mill recovery rates. The current results are preliminary but Starfield management is pleased with the outcome and additional metallurgical studies are planned to advance the metals recovery phase of the project.
