This new geological map provides new insight into the geology, geochronology and mineral potential of the Iron Mask Batholith in the Kamloops region of southern British Columbia.  It presents the results of new mapping and a compilation of University  and private industry research designed to clarify the copper-gold metallogeny of the batholith. Past metal production from the batholith includes the Afton copper-gold-silver-PGE bearing deposit. Delineation of additional reserves and a likely return to production by New Gold Resources makes correlative rocks important exploration targets throughout the batholith and underlines the potential for new discoveries and mines in the area.


The Iron Mask survey was delivered with support from the Rocks to Riches (AMEBC) program and Geoscience Partnerships developed between Abacus Mining and Exploration, Imperial Metals Corporation and Nova Gold Corporation to study alkaline porphyry copper-gold deposits.


Integrated Airborne Geophysical, Geology and Mineral Occurrence Data, Iron Mask Batholith is available in Open File 2006-12.  The geophysical data represents a subset of the 1995 Iron Mask Survey completed by the Geological Survey of Canada and released as BCMEMPR Open File 2005-13 and GSC Open File 2817.  See GeoFile 2006-5 for a review of the regional geological setting, tectonics, geochronology, geophysics, mineralization and alteration characteristics of the Iron Mask Batholith.
