June 2013: Added Geoscience BC Reports:
2013-09: Nelson (082F) Sample Reanalysis (ICP-MS): Geoscience BC Report 2013-09 presents ICP-MS results for stream sediment samples collected during the original 1977 Nelson RGS program. Results from the 1977 Lardeau RGS program were released in January 2013 as Geoscience BC Report 2013-04. The Nelson regional geochemical survey was conducted in 1977 and included the collection of 1394 stream sediment samples. In co-operation with the BC Geological Survey (BCGS) and Natural Resources Canada (NRCan), samples saved from the survey work were retrieved from storage facilities in Ottawa. A total of 1554 drainage-sediment and quality-control samples were subsequently delivered to Acme Analytical Laboratories Ltd. (Vancouver, BC) and analyzed by an ultra-trace aqua-regia digestion (0.5 g) ICP-MS technique for 53 elements
2013-04: Lardeau (082K) Sample Reanalysis (ICP-MS): Geoscience BC Report 2013-04 presents ICP-MS results for stream sediment samples collected during the original 1977 Lardeau RGS program. The Lardeau regional geochemical survey was conducted in 1977 and included the collection of 1297 stream sediment samples. In co-operation with the BC Geological Survey and Natural Resources Canada, samples saved from the survey work were retrieved from storage facilities in Ottawa. A total of 1435 drainage-sediment and quality-control samples were subsequently delivered to Acme Analytical Laboratories Ltd. (Vancouver, BC) and analyzed by an ultra-trace aqua-regia digestion (0.5 g) ICP-MS technique for 53 elements. Due to a deficiency of available material, one sample was not included in the reanalysis work.
2013-06: McLeod Lake (093J) Sample Reanalysis (INAA): Geoscience BC Report 2013-06, presents INAA results for stream sediment samples collected during the original 1985 McLeod Lake RGS program. The McLeod Lake regional geochemical survey was conducted in 1985 and included the collection of 1152 stream sediment samples. In co-operation with the BC Geological Survey and Natural Resources Canada, samples saved from the survey work were retrieved from storage facilities in Ottawa. A total of 1273 drainage-sediment and quality-control samples were subsequently delivered to Becquerel Laboratories Inc. (Mississauga, ONT) and analyzed by INAA for 35 elements. Due to a deficiency of available material, seven samples were not included in the reanalysis work. Weighed and encapsulated samples were packaged for irradiation along with internal standards and international reference materials. Samples and standards were irradiated together with neutron flux monitors in a two-megawatt pool type reactor. After a seven-day decay period, samples were measured with a high-resolution germanium detector. Typical counting times were 500 seconds.
2013-11: Regional Stream Sediment and Water Geochemical Data, Northern Vancouver Island (092K, 092L, 102I): A total of 721 moss-trapped sediment samples plus water were acquired from 681 stream sites located in a 10,000 km2 survey area north of the communities of Campbell River and Zeballos, within NTS 1:250 000 map sheets 092L, 092K and 102I. Sample locations were selected to increase geochemical coverage and combined with historical survey work (see Geoscience BC Report 2013-12), the resulting average sample site density has been improved to one site every 5 km2.
2013-08: Ice Flow Patterns in 093G, & J, and Detailed Ice Flow History for 093J: The map contained within this report shows ice flow patterns for NTS 093G, H (west) and J, and detailed ice flow history for parts of NTS 093J (near Prince George, BC). The report also contains a regional ice flow model for the northern Interior Plateau region. Constructed from previous mapping and recent field studies, the report is intended as an aid to mineral exploration in central BC. The report consists of one PDF sheet, and the ESRI ArcGIS shapefiles of striations, regional ice flow and detailed ice flow data.
