http://www.empr.gov.bc.ca/Mining/Geoscience/PublicationsCatalogue/GeoFiles/Pages/GF2010-14.aspx

 

As part of the QUEST South regional geochemical studies sponsored by Geoscience BC, a total of 785 stream samples were collected in southern British Columbia in 2009, with analytical results published in 2010 (Jackaman, 2010).

 

The BC Geological Survey recently delineated catchment basins for these new infill stream sites, after extensive validation and adjustment of the sample locations to the TRIM streams.  Detailed methodology on the delineation of catchment basins was described and published by Cui, et el. (2009).

 

The release of the catchment basin data for these sample sites is to complement and enhance the values of the Geoscience BC publication, in the advancement of the levelling, interpretation, application and presentation of the geochemical results for mineral exploration.

Geology of the Area South and West of Princeton, British Columbia (parts of NTS 92H/01, 02, 07, 08 and 10), 1:50 000 -scale

Mapping and compilation by N.W.D. Massey, J.M.S. Vineham and S.L. Oliver

Geoscience Map 2010-04

http://www.empr.gov.bc.ca/Mining/Geoscience/PublicationsCatalogue/Maps/GeoscienceMaps/Pages/2010-4.aspx

 

The map covers an area centred about 15 km to the southwest of Princeton.  The map stretches from the Copper Mountain and Wolfe Creek area southwest to East Gate and the boundary of Manning Park and northwest to the Tulameen River. 

 

The map area lies at the western edge of Quesnellia and includes some of the southernmost exposures of the late Triassic Nicola Group.  To the east of the Boundary Fault, rocks of the Nicola group are assigned to the "Eastern Belt" (Preto 1979; Mortimer 1987).  Interbedded black argillites, grey siltstones and sandstones are overlain by volcanic and volcaniclastic rocks of the Wolfe Creek Formation, which display an alkalic affinity.  They host the important porphyry and skarn deposits of the Copper Mountain area (Preto, 1972).

Geological Setting of Mesozoic Precious Metal Mineralization in East-Central Stikine Terrane

This field trip presents explorationists with the opportunity to visit Silver-Gold-Base Metal Disseminated Deposits at Capoose and Blackwater-Davidson with mining company experts that are currently exploring these mineralized systems.  these deposits are 23 km apart, located within the Fawnie Range which is underlain by Mesozoic volcanic and sedimentary rocks that form part of the Nechako horst.  The deposits developed in late Cretaceous time (ca. 67-72.5 Ma) in association with hypabyssal garnet-bearing rhyolite dikes/sills, and related extrusive volcanic rocks.

 

The oldest known mineralization in the Nechako horst is the 3Ts Gold-Silver Deposit, a serious of en-echelon, north-trending quartz-carbonate veins with characteristics of low-sulphidation epithermal deposits. Veins at the 3Ts are located south of the Laidman stock, a latest Jurassic (ca. 148 Ma) quartz monzonite.  Gold mineralization post dates, by several million years, crystallization of this pluton and nearby comagmatic gacitic volcanic rocks.  A Cretaceous (ca. 74 Ma) microdiorite sill cross cuts the veins.

Till data presented here highlight four areas of elevated geochemical values of interest to the mineral exploration community.  The spatial distribution of samples elevated in Cu, Mo, Pb, Zn, Ag, Ni, Hg, Au, As, Sb, Cr and visible gold grains are the focus of this study.  Follow-up field work is required to assess the significance of the elevated element values used to identify these areas.  The silt plus clay-sized fraction of 79 basal till samples, collected approximately 100 km south of Houston, BC, were analyzed for 37 elements by inductively coupled plasma mass spectrometry (ICP-MS), following an aqua regia digestion, and 35 elements by instrumental neutron activiation analysis (INAA).  An additional 16 basal till samples were collected for analysis of heavy metal concentrates and gold grain counts.

Evidence of westward glacial dispersal along a till geochemical transect of the Copper Star
Cu+/-Mo+/-Au occurrence, west-central British Columbia
by T. Ferbey and V.M. Levson

Open File 2010-04

 

http://www.empr.gov.bc.ca/Mining/Geoscience/PublicationsCatalogue/OpenFiles/2010/Pages/2010-4.aspx

A 2.5 km east-west geochemical sampling transect over the Copper Star porphyry occurrence in an area of a known ice-flow reversal reveals evidence for dominantly westward (locally 290°) glacial dispersal.  The highest Cu (686.1 ppm) and Mo (4.98 ppm) values in the till transect occur directly west of the occurrence and generally decrease westward.  The second highest Cu value (194.78 ppm), however, occurs in till directly east of the occurrence suggesting that a component of eastward dispersal also occurred.  These observations are consistent with the ice-flow model for the area that predicts both eastward and westward dispersal.  Dispersal distance from the mineral occurrence to the highest Cu concentration in till is short, probably reflecting the shallow till depth (<1 m) at the occurrence.  In addition, elevated Au and Ag at two sites at the east end of the transect suggests potential precious metal mineralization in that area.

 

Biogeochemical orientation survey data from NTS 93F/2 and 7 (Davidson-Blackwater): Outer bark of lodgepole pine

by C. Dunn and V.M. Levson
Open File 2010-05

 

http://www.empr.gov.bc.ca/Mining/Geoscience/PublicationsCatalogue/OpenFiles/2010/Pages/2010-5.aspx

Results from the analyses of the outer bark of lodgepole pine collected at 51 sites in the Interior Plateau region of central British Columbia are presented. The biogeochemical samples were collected from the Tsacha Lake (NTS 93F/2) and Chedakuz Creek (NTS 93F/7) 1:50 000 scale map areas. The concentrations of 44 elements in the ash of the bark samples are presented. The mean concentrations of most elements, including lead, zinc, copper, silver, nickel, gold, arsenic and antimony, are higher than in a larger regional survey conducted just to the northwest. Likewise the maximum concentration of most elements, including gold, arsenic, silver, nickel and zinc, are higher than in the survey to the northwest.  In particular, mean and maximum concentrations of gold (40ppb and 733 ppb, respectively) are an order of magnitude higher. The three highest concentrations of gold (733,408, 109 ppb) are clustered in one area southwest of Top Lake. Concentrations of the pathfinder element arsenic are also elevated at these sites (10-12 ppm; >75th percentile). The anomalously high gold concentrations, clustering of the three sites, and high associated arsenic concentrations, suggest that there is an undiscovered gold occurrence in this area. An additional area of interest, with the fourth highest gold occurrence in the study area (74 ppb), occurs in the Big Bend Creek area. Two nearby sites have elevated gold (18-25 ppb) and one of these shows more than 90th percentile arsenic (15 ppm) and antimony (2.6 ppm) No mineral occurrences have been recorded in this area or at a number of other identified locations with high metal concentrations.

 

Age of Cu-Au-Ag mineralization at Copper Mountain:  Parta of a ~200 Ma copper epoch in BC
by M.G. Mihalynuk, J. Logan, R.M. Friedman, V. Preto
Geofile 2010-06

 

http://www.empr.gov.bc.ca/Mining/Geoscience/PublicationsCatalogue/GeoFiles/Pages/2010-6.aspx

A chain of alkali Cu-Au±Ag-Mo porphyry deposits and coeval instrusive and volcanic rocks extend the length of the Canadian Cordillera. They are the product of a prolific metallogenic event.  Mineralization at Copper Mountain is part of this event; recognized by workers in the 1970’s as coeval with intrusions that host the mineralization along with nearly coeval volcanic rocks. However, by the mid 2000’s this nearly coeval relationship was challenged by time scale revisions, changes to isotopic decay constants, improvements in dating techniques and over-interpretation of earlier cooling ages. If the isotopic age data were taken at face value, the mineralization at Copper Mountain appeared to be nearly 10 million years younger than the host rocks. With a new era of deep porphyry exploration about to begin, it was imperative to know whether mineralization was related to a younger, perhaps hidden intrusion or if existing age data were misleading.

Williams Lake to Mackenzie (an area larger than Vancouver Island).

 

The revised geology for this region has been generated by geological, geophysical and geochemical experts

from the three organizations.  The project incorporates geophysical and geochemical data from Geoscience BC's

QUEST project, geophysical data from Natural Resources Canada and recent bedrock mapping by the British

Columbia Geological Survey.  The BCGeologyMap QUEST Area update focuses on the volcanic and intrusive

rocks of the Quesnel Terrane in central British Columbia, which are prospective for copper and gold deposits

but covered by glacial deposits in the center of the update area.

 

New interpretations are expected to benefit the mineral exploration community working in the region.

 

In addition to the new map for the area, the update is also being seamlessly incorporated into the digital

bedrock geology for BC.  A preliminary version of the digital file is also available in shape or manifold files

as part of this release.  A second update will be released and incorporated into MapPlace when the final digital

data is available (www.mapplace.ca).

 

The hardcopy map and associated GIS files can be downloaded here:

Additionally, a draft copy of the digital BCGeologyMap, updated to include new information from the Bedrock

Geology of the QUEST area map, is available for download.  This draft of the digital BCGeologyMap is the

starting point to streamline integration of past and future geological mapping results into the provincial database. 

A future release will include enhanced metadata, cleanup of line work due to projections issues and the integration

process methodology.  http://www.empr.gov.bc.ca/Mining/Geoscience/BedrockMapping/pages/BCGeoMap.aspx

 

About BCGeologyMap

 

The BCGeologyMap is British Columbia's online digital geology map, maintained by the British Columbia

Geological Survey.  The map was originally compiled from geological maps by the British Columbia Geological

Survey, Geological Survey of Canada, university and industry geologists.  The digital geology is available for free

through MapPlace (www.MapPlace.ca) or 2005 versions are available as GeoFiles 2005-1 to 2005-10 (link to GeoFiles).

Expanded vermiculite is used as a lightweight aggregate in concrete, an additive in a variety of acoustic, thermal and fire insulation products, in soil conditioning, as a fertilizer or insecticide carrier, and in absorbent packing, paints and sealants.  There is currently no vermiculite produced within the province of British Columbia.  Only four localities in the BC MINFILE list vermiculite as a commodity.

 

Carbonate-hosted sulphide and nonsulphide Pb-Zn mineralization, Cariboo Terrane, BC, Canada

S. Paradis, G.J. Simandl, J. Bradford, C. Leslie and C. Brett

Geofile 2010-04

http://www.empr.gov.bc.ca/Mining/Geoscience/PublicationsCatalogue/GeoFiles/Pages/2010-4.aspx

Under favourable geological, climatic, topographic and hydrological conditions, the weathering of carbonate-hosted, sulphide deposits may result in the formation of economically significant direct replacement and wallrock replacement nonsulphide base metal deposits.  Nonsulphide deposits were the main source of zinc in the 19th century.  Due to the metallurgical innovations during the early 20th century, the interest of explorationists shifted to sulphide ores.  For a variety of environmental and economic reasons, nonsulphide deposits are again representing attractive exploration targets; however, they are commonly overlooked.

Non-metallic minerals other than coal:  Industrial minerals, gemstones and aggregate in
British Columbia, Canada
G.J. Simandl
Paper 2009-2

 

http://www.empr.gov.bc.ca/Mining/Geoscience/PublicationsCatalogue/Papers/Pages/2009-2.aspx

Non-metallic minerals other than coal are an increasingly significant component of international trade.  British Columbia is

strategically located on the west coast of North America and has well-developed infrastructure in the southern, more

populated third of the Province, including several deep-water ports, and a well-maintained highway system.  Rail 

links British Columbia's industrial centres to terminal points across the continent.  The Province has attractive energy

costs and untapped mineral resources.

 

The main industrial minerals other than coal produced in British Columbia are magnesite, limestone, gypsum, sulphur

(derived as a byproduct from oil and gas processing), construction aggregate, crushed rock, silica, dimension stone

and white calcium carbonate.  In lesser quantities, jade (nephrite), magnetite, dolomite, barite, volcanic cinder,

pumice, flagstone, clay, tufa, bentonite, Fuller's earth and zeolites are also produced.

 


Regional to property-scale drift prospecting surveys in British Columbia
T. Ferbey
Geofile 2010-05


http://www.empr.gov.bc.ca/Mining/Geoscience/PublicationsCatalogue/GeoFiles/Pages/2010-5.aspx

 

Presented here is a geographically referenced list of drift prospecting surveys that have been conducted in

British Columbia.  A list of topical studies and special volumes that are relevant to drift prospecting in British

Columbia have also been included.  These studies and geochemical data will be of interest to explorationists

and researchers who are assessing the effectiveness of drift prospecting surveys in the context of their own

exploration or research program, who are preparing to design and implement their own survey, or who have

generated geochemical data on drift samples and are looking for data from orientation surveys for

comparison.

 

This map and list of references is intended to provide a way of quickly identifying drift prospecting studies and

data that are either geographically or topically of interest to those working in British Columbia.  Any omission

in the reference list or on the map should be brought to the attention of the compiler.  This publication will be updated

on an annual basis.
