Lac Knife Flake Graphite Orebody: A Long Term Stable Source Of Supply

During the 1980 decade, the rapid price increase for flake graphite has generated a high degree of interest for the discovery and the development of alternate occidental sources of supply in response to fluctuations in quality and availability from current producers. Alike many industrial minerals, graphite draws its complexity not only from its mineralogy and unique properties but also from the very large spectrum of industrial applications each calling for specific quality criterion. As new high technology uses are being developed, more rigid specifications will apply. Discovered during the latter part of 1988 by Mazarin inc., some 30 Km South of Fermont near the Quebec-Labrador border, the Lac Knife deposit was quickly identified as one of the world major long term alternate source of stable supply for this mineral. This paper also reviews the status of the project development as of late 1991, while updating previous papers published by Industrial Minerals1990 and Mining Magazine 1990.
