***********************************
The British Columbia Geological Survey has completed extensive geological mapping and
mineral deposits studies on northern Vancouver Island over the last decade. This is an ongoing
program of mapping and mineral deposits studies. Northern Vancouver Island, and particularly the Quatsino Sound area, is
richly endowed in mineral occurrences, has had a successful mining history, such as the former Island Copper mine. The region
also has numerous mineral occurrences, some of which are under-explored but with excellent potential. The release of these
three 1:50 000-scale Geoscience Maps covers an area extending from Winter Harbour - San Josef Bay on the west coast to Port
Hardy - Port McNeill on the east coast, an area encompassing NTS sheets 102I/8, 9 and 92L/6, 11, and 12.

D.A. Archibald, R.M. Friedman, T. Tozer, H.W. Tipper, T.P. Poulton, J. Palfy, F. Cordey, D. J. Barron and K.A. Johnston
The area is underlain by a folded and faulted sequence of
Upper Triassic to Middle Jurassic volcanic and sedimentary rocks of the Vancouver and Bonanza Groups intruded by granitoids
of the Island Plutonic suite. The latter rocks are associated with important calcalkaline Cu-Mo-Au porphyry, and base and
precious-metal skarn and epithermal mineral occurrences. Cretaceous marine clastic and Tertiary volcanic-sedimentary strata
with lower mineral potential overlie the Triassic-Jurassic rocks.
These geoscience maps provide a new stratigraphic framework
for the Early Mesozoic sequences, calibrated by 40Ar/39Ar and U-Pb isotopic dating and macrofossil and microfossil (conodont
and radiolarian) faunas. The Bonanza group now includes the Upper Triassic Parson Bay Formation, which contains mapable
volcanic/volcaniclastic horizons, overlain by unnamed volcaniclastic-sedimentary strata of uppermost Triassic to lowermost
Jurassic age, in turn succeeded by Lower to Middle Jurassic, predominantly volcanic and volcaniclastic sequences of the
informally named LeMare Lake volcanics, formerly "Bonanza volcanics". The latter term is usefully retained for all volcanic
lithologies within the Bonanza Group, which spans some 40 million years of magmatic arc evolution from the Late Triassic (Carnian) to
the Middle Jurassic (Bajocian).

Re-analysis of Regional Geochemical Stream Sediment Samples
from the McLeod Lake area
(NTS 93J)
By Ray Lett and Britt
Bluemel
Digital Data and Report are
available from:
http://www.em.gov.bc.ca/Mining/Geolsurv/Publications/GeoFiles/Gf2006-09/toc.htm
Geofile 2006-09
reports new gold and trace metal
data from the re-analysis of archived regional geochemical survey samples from the
McLeod Lake (NTS 93J)
map sheet. Up to 147 ppb gold in sediment was detected from an area underlain by Takla rocks.
This digital release consists of a report in PDF format, and appendices in a ZIP format file.
Previous exploration in the McLeod Lake area has
been hampered by a thick glacial sediment blanket. There are 25 reported mineral occurrences
which include 6 gold and 2 copper showings. Part of the map sheet is underlain by Triassic
Takla Group rocks that can host significant porphyry gold-copper deposits, such as that at
Mount Milligan immediately west of the area. In 1985 a regional geochemical survey produced
trace element data from the analysis of 1152
stream sediments and 940 water samples taken from 1088 sites over a 14 500 km2.
The sediment samples were originally analyzed for 19 trace elements including copper, lead,
zinc, uranium, fluorine, barium, tin and tungsten. They were also analyzed for loss on
ignition (LOI). The samples were re-analyzed this year for 37 elements including gold by aqua
regia digestion - inductively coupled plasma mass spectrometry (ICP/MS).
-----------------
Stream sediment analyses, from
several regional geochemical surveys, carried out by the
BC Geological Survey in the Bella Coola area of coastal British Columbia have
been compiled into a single file for convenience and to accompany 2006 geological map product
releases from the Geological Survey of Canada
and the BC Geological Survey.
These multi-element data can assist geologists and mineral industry companies in identifying
prospective exploration areas for new mines.

appendices in a ZIP format file.
The Bella Coola-Whitesale Lake area is underlain by Mesozoic Hazelton Group, Coast Complex
plutonic rocks and Cretaceous-Tertiary intrusive rock and has the potential for volcanogenic
massive sulphide (VMS) mineralization, precious metal vein and Cu-Mo porphyry deposits. A
compilation of geoscience information for the Bella Coola area will be published by the
Geological Survey of Canada in cooperation with the BC Geological Survey. This geochemical
Geofile data product comprises analyses of 790 samples for 17 trace elements, loss on
ignition (LOI) and stream water pH extracted from BC Regional Geochemical Survey reports 56
and 16 and these data have been combined into a single file for convenience. Elements
selected were determined by similar analytical methods in the two surveys. Element variations
across the area are shown as symbol maps.

MEMPR Geofile 2006-11 reports new regional geochemical drainage sediment – water survey data from
the Anahim Lake (NTS 93C) and Nechako River (93F) map sheets. This digital release consists of a
survey summary, data listings, statistics and maps in PDF format, plus appendices containing raw
data and GIS importable shape files.
There are over 60 base and precious metal occurrences in the Anahim Lake - Nechako River map
sheets including several such as the 3T’s and Clisbako, which have extensive exploration history.
However, exploration for new deposits has been hampered by widespread glacial sediment and Miocene
lava cover. During 2005 a total of 2070 drainage sediment and water samples were collected from
1957 sites covering 19 500 square kilometres. Most of the samples were taken from lakes and
analysed for trace and minor elements by instrumental neutron activation and by aqua regia
digestion - inductively coupled plasma mass spectrometry (ICP/MS), for loss on ignition (LOI) and
for fluorine. Water samples were analysed for pH, conductivity and fluoride. Survey data has been
combined with the results of two previous lake sediment and water geochemical surveys completed
near the Fawnie Range and around Ootsa Lake. Gold values up to 694 ppb and copper up to 1536 ppm
have been detected in sediment samples.

Geoscience Initiative II - Mining Company Partnership
This geological map is the result of a 1:20 000-scale bedrock
mapping program conducted from 2003 to 2005 as part of a partnership between the BC Geological Survey and
Stealth Minerals Ltd., Northgate Exploration Ltd., Finlay Minerals Ltd., Bishop Resources Inc., Sable
Resources Ltd., the Geological Survey of Canada, and the University of British Columbia.
This map covers approximately 900 km2 of mountainous terrain between the Finlay River and Chukachida
Lake, and extends the detailed map coverage at 1:20 000-scale farther to the north beyond published BCGS
Geoscience Map 2001-1, centred on the Kemess South Au-Cu porphyry mine. It portrays an updated and revised
stratigraphy for the Early Jurassic Toodoggone Formation and comagmatic plutons of the Black Lake intrusive
suite. The Toodoggone Formation in the map area is largely composed of a previously unrecognized
stratigraphic succession that is subdivided into 4 new units (i.e., Belle, Pillar, Graves and Junkers).
These units consist mainly of subaerial basalt to rhyolite volcanic rocks and derived sedimentary rocks that
were deposited between 194 Ma and 186 Ma. They overlie the previously defined, pre-194 to 200Ma Toodoggone
Formation, and older Late Triassic basement and occur above an erosional unconformity.
Regionally the Toodoggone Formation is noted for numerous epithermal precious metal occurrences and quartz
monzonite to monzonite plutons of the Black Lake intrusive suite locally host Au-Cu porphyry mineralization.
Copper-magnetite skarns are locally developed within Early Permian limestones of the Asitka Group crosscut
by Early Jurassic plutons.
Geology of the Canim Lake Area (092P/15)
Open File 2006-8
1 sheet at 1:50 000-scale by Paul Schiarizza & Amy Boulton
The Canim Lake map area covers about 1000 square kilometres within the
Quesnel Highland and Fraser Plateau of south-central British Columbia. This new geological map is based on
fieldwork conducted during 2005. The map area is underlain mainly by sedimentary, volcanic and
volcaniclastic rocks of the Middle to Upper Triassic Nicola Group, together with Late Triassic to Early
Jurassic ultramafic to granitic plutonic rocks. These rocks are part of the Quesnel magmatic arc, which
hosts the Afton and Mount Polley porphyry Cu-Au deposits to the south and north, respectively. Younger rocks
in the map area include mid-Cretaceous granitic stocks and batholiths, Eocene volcanic and sedimentary
rocks, and Quaternary basalt. Mineral occurrences located within the map area include disseminated and
fracture controlled Cu-Au (locally with Pt, Pd) within ultramafic, dioritic and monzonitic rocks of the
Quesnel arc suite, as well as porphyry Mo within mid-Cretaceous granite and Au-bearing quartz-carbonate
veins and mineralized shears.

FOR IMMEDIATE RELEASE
The search for, and discovery of, diamond deposits in Canada has had a
significant impact on Canada’s economy over the past decade. Canada is now the number three producer in
the world for these high-quality gemstones and is believed to have significant and untapped potential for
new discoveries.
Recent work by the BC Ministry of Energy, Mines and Petroleum Resources
staff highlights the fact that the potential for diamond occurrences in the northeast of the province is
better than previously assumed. Some diamond indicator minerals have been identified by limited, regional
sampling.
Approximately 400 km southeast of Fort Nelson, in Alberta between Fort
McMurray and the Peace River, there are areas with similar geology and diamond occurrences, but no mines.
Comprehensive exploration of northeast British Columbia would be required to properly assess this diamond
potential.
Kimberlite and Diamond Indicator Minerals in Northeast British Columbia, Canada – A Reconnaissance Survey

Northeast British Columbia is an under-explored region of North America
for diamonds, other gemstones and minerals. The area has a low relief and extensive glacial and fluvial
surficial materials which add a challenge to exploration programs. BC Ministry of Energy, Mines and
Petroleum Resources staff investigated this region by collecting approximately 58 samples from a variety of
materials within northeast British Columbia, to test for kimberlitic indicator minerals and the potential
for diamond-bearing bedrock.
Since diamonds occur in neighbouring parts of Alberta with similar
geology and are mined in basement rocks of the Northwest Territories which are believed to extend under
northeast British Columbia, there is the potential to discover diamonds in this region. Diamonds have been
discovered within the Buffalo Head Hills and Birch Mountain areas of neighbouring Alberta, approximately 400
km southeast of the Fort Nelson. As well, several alluvial diamond occurrences are reported adjacent to
northeast British Columbia in the Northwest Territories and in Alberta.
Recent age dating of basement rocks in the northeast indicates that a
Precambrian crystalline basement, similar in age to the Buffalo Head Terrane, extends farther west than
previously expected, supporting the hypothesis that northeast British Columbia may have been underlain by a
thick, cold lithosphere prior to rifting of the Rodinia Supercontinent. The deeper portions of the
“diamondiferous root” may subsequently have been destroyed after the diamonds were brought to the surface by
kimberlites, lamproites, or other diamond host rocks.
The results of this limited, heavy mineral reconnaissance survey carried
out by the BC Geological Survey, when considered in conjunction with the findings of a previous kimberlite
indicator mineral survey, provides new evidence for diamond potential in the northeast of the province.

Emeralds have recently been found in the Yukon and this report evaluates
the potential to find them in British Columbia. Emerald, a gem variety of the mineral beryl, is a
high-value commodity for which even small deposits could be economically interesting. There has been
relatively little prospecting and exploration for gemstones in the province, therefore, there are
significant opportunities to find gem and semi-precious stones. This study identifies the areas in British
Columbia that are believed to have the best potential for emerald discoveries.
Potential for Gem Beryl and Schist Hosted Emerald

This 20-page report reviews the gem varieties of beryl, the associations
of beryl with granitic rocks, and the particular association of emerald with ultramafic wallrocks affected
by volatile-rich fluids. The publication includes an emerald potential map for the province and a general
description of areas of gem beryl potential. There has been little systematic work on transparent gemstones
in British Columbia in spite of a number of gem discoveries in the last fifteen years. This study received
funding from the BC and Yukon Chamber of Mines, Rocks to Riches program in 2004, which provided support for
some limited fieldwork related to known emerald and beryl occurrences in the province.
