Objective(s): The research team proposes a two-year (2001-2003) collaborative study between the Geological Survey of Canada (Calgary) and the C.S. Lord Northern Geoscience Centre (NWT), to delineate and describe the origin, distribution and potential for carbonate-hosted lead-zinc occurrences. The study area includes Cominco's Pine Point Mine, which produced 83 M tonnes of ore between 1964-1987. The project will examine the host lithology, associated structure, and geochemical signatures of lead-zinc deposits to address the source and pathways of the mineralizing fluid, and the timing of ore deposition for the purpose of advancing exploration models in the Northwest Territories.

Project Description: Transport of the research team to sites will be by truck, contingent on road access. Tent camps will be established for housing in the field. The camp will consist of 2 researchers, for the months of August and September, with possible sporadic visits by other researchers throughout the summer. Field activities will involve examining and documenting lead-zinc occurences, and collecting lead-zinc samples (and the rocks that are proximal to them; sample size approximately 1 kg), on mineral claims owned by Cominco and Boliden at Pine Point. All field observations documented during the day will be entered into a computer database. Once all mineral occurences within walking distance of the camp have been examined, the camp will be re-located. All human waste will be buried, and all non-burnable garbage will be packed out. The research team will attempt to minimize contact with all wildlife.
