GeoFile 2007-5:  Results of Reconnaissance Surveys in the Interior Plateau Beetle Infested Zone (BIZ)

by Mihalynuk, M.G.; Harker, L.L.; Lett, R.E.; Grant, B.


Geofile 2007-5 is part of an economic diversification initiative by the Province of BC, which aids communities affected by the Mountain Pine Beetle.
Pine forests extend across much of the interior plateau of southern British Columbia where they are the principal commercial tree species. These forests are infested by the Mountain Pine Beetle, and it is estimated that by 2016 less than ~10% of the already diminished 2006 volume of pine will be left standing. Economic welfare of the many forestry-dependent communities in the Beetle Infested Zone (BIZ) will be severely impacted. Anticipating an economic downturn in the forestry sector, the Provincial Government is supporting economic diversification throughout the region via stimulation of other industries. Work presented in Geofile 2007-5 is a part of that provincial effort aimed at stimulation of new jobs in the high-paying mineral exploration and mining industries.

Reconnaissance field studies conducted during 2006 as part of the BIZ Project were aimed at optimizing the design of future BC Geological Survey field programs within the BIZ. A principal objective of the project is to demonstrate how application of conventional and non-conventional exploration techniques can be successfully applied to large tracts of the BIZ, and how geoscientific information can best benefit British Columbians living within the BIZ.

Results of the 2006 program are presented in Geofile 2007-5 as two parts:
