These three colour Geoscience Maps (1998-2, 1998-3, & 1998-4) cover areas in the Purcell anticlinorium. Exploration attention is focused in the Purcell anticlinorium, targeting favourable settings for new SEDEX deposits using the features found at the world class Sullivan Pb-Zn-Ag mine as indicators.  The maps provide 1:50 000 scale geology with Sullivan-style indicators (e.g. sedimentary fragmentals, tourmalinite, albite alteration, garnet-rich zones) clearly shown and the locations of diamond drill holes.


Geoscience Map 1998-2 covers the core of the Moyie anticline and mineral occurrences in the Mt. Mahon-Yahk area.  Map 1998-3 includes the extensively explored Fors-Vine areas and the newly discovered Panda Basin.  Map 1998-4 covers the Findlay-Doctor Creek area, where recent drilling has identified stratiform sulphides in Upper Aldridge strata.
