Selected British Columbia Mineral Deposit Profiles
Volume 2 - More Metallic Deposits


BCMEMPR Open File 1996-13

 

by Lefebure, D.V. and Höy, T.

 

The British Columbia Geological Survey started a mineral potential assessment in 1992 utilizing deposit models for defining and characterizing mineral and coal deposits which exist, or for which favourable geological environments could exist, in the province.  These deposit models are being used to classify known deposits and occurrences, to guide experts in their estimation of the number of possible undiscovered mineral deposits, and to group deposits to allow compilation of representative grade and tonnage data.

 

The Branch formerly relied on mineral deposit models published by the United States Geological Survey (USGS) and Geological Survey of Canada (GSC).  However, it became apparent that some models needed revision, and that there are British Columbia deposit types lacking published models.  Hence we developed a set of mineral deposit profiles using the Branch's considerable in-house expertise, with assistance from economic geologists of the GSC, USGS, industry and academia.

 

These deposit models are called "deposit profiles" to distinguish them from other published descriptions.  This Open File 1996-13 is the second report containing deposit profiles and includes descriptions of a variety of metallic deposits, including epithermal, vein and manto deposits that were not covered in the first report (Volume 1):
