In 2018, the BCGS had field projects
throughout the province. In the northwest,
the BCGS partnered with the Geological
Survey of Canada (GSC) in the final year of a
Targeted Geoscience Initiative (TGI4) project
assessing gold deposits near the Llewellyn
fault and its possible extension into Yukon
as the Tally Ho shear zone. Work continued
on a major regional program focused on the
"Golden Triangle," including a study near
Iskut and a BCGS-GSC collaboration under
TGI5 looking at geodynamic controls on
porphyry and epithermal-style mineralization
near Stewart. In central B.C., a new multi-
year mapping project was initiated focused
on the northern part of the Hogem
batholith. The new mapping will provide a
modern understanding on the controls of
diverse mineralization types in the region,
particularly porphyry deposits. North of
the Hogem batholith, another BCGS-GSC
TGI5 project was initiated to examine the
geological framework of the Polaris intrusion.
This project builds on ongoing work of the
Tulameen ultramafic body, and is designed
to further refine our understanding of
Ni-Cu-PGE ore-forming processes in
these Alaskan-type intrusions. In southern
B.C., multi-year projects re-defining the
stratigraphic framework of the Nicola arc
entered their final field seasons, and a new
project targeting Co-rich volcanogenic
massive sulphide deposits in the Kootenay
arc started. Work continued on the Upper
Fir Rare Earth element deposit and will
incorporate data gathered from the Ice River
carbonatite body. Also part of TGI5, is a joint
BCGS-GSC-Geological Survey of Japan
collaboration examining specialty metals.
BCGS continues to develop new exploration
methods, including indicator minerals from
till. Program results are presented each
year at an Open House held in Victoria and
at annual meetings such as Roundup, the
PDAC, KEG and Minerals South, and are
published in Geological Fieldwork, a volume
of papers released by BCGS each January.
As custodian of all provincial public
geoscience data, the BCGS preserves,
archives, and provides free web-based
access to more than a century's worth of
information. The BCGS houses, maintains
