Discover Abitibi Initiative

The Discover Abitibi Initiative is a regional, cluster economic development project providing geoscientific investigations of the Western Abitibi Greenstone Belt in Ontario. The project has brought together funding partners FedNor, Northern Ontario Heritage Fund Corporation and the private sector to complete projects, which will further stimulate exploration activity and mining in this prolific belt. To support this successful endeavor, user stakeholders have provided the project ideas. The technical expertise to evaluate the projects has been provided by volunteers on the technical and management committees. Further information regarding this initiative can be found at http://www.discoverabitibi.com or by contacting the Timmins Economic Development Corporation by email at tedc@timmins.ca.

Regional Lithogeochemical Study of the Kidd–Munro MEGATEM® Survey Areas, Timmins–Kirkland Lake Region, Northern Ontario: Discover Abitibi Initiative; by M.D. Hannington, A. Coombs, G. van Hees, S. Duff and N. Campos-Alvarez. This release presents the results of a lithogeochemical study of the Kidd–Munro area in the Timmins–Kirkland Lake region of northern Ontario, with an emphasis on carbonaceous argillite units associated with base metal and gold mineralization, and with particular attention to the areas covered by the 2002–2003 MEGATEM® surveys and in adjacent townships. New whole-rock lithogeochemical data on 564 samples of carbonaceous argillites in drill core were used to characterize the lithogeochemistry of interflow metasedimentary units associated with a wide range of mineralization styles hosted by metavolcanic rocks and clastic metasedimentary units throughout the study area. Samples were obtained from the MNDM core archives at Timmins and Kirkland Lake, and from 19 mining and exploration companies operating in the region. The sampled area includes 76 townships, encompassing an area of more than 15 000 km2. Complete, high-precision analytical data for 67 elements are provided, together with a preliminary analysis of the data. A portable X-ray fluorescence (XRF) analyzer was also used to test the reliability of field-portable units in the detection and analysis of selected pathfinder elements in carbonaceous argillite. The main products of this study are 1) a report outlining the project methods, results and products (portable document format (.pdf) files); 2) maps illustrating the regional distribution of sampled carbonaceous argillite units, together with quartile plots of the data distribution for selected pathfinder elements (ESRI® ArcGIS® 10.0 and 9.2 and portable document format (.pdf) files); 3) sample description information (Microsoft® Excel® 2003 (.xls) format files); 4) tables of whole-rock lithogeochemical data for the analyzed samples (Microsoft® Excel® 2003 (.xls) format files); and 5) summary statistical data used to characterize the geochemistry of different argillite lithotypes (Microsoft® Excel® 2003 (.xls) format files). The products of this study will aid explorationists in identifying areas of anomalous metal enrichment in drilled carbonaceous argillite units that may be related to volcanic-hosted base metal deposits, ultramafic-associated nickel deposits, and volcanic- and sedimentary-hosted orogenic gold deposits in the region. Location data are provided in the Universal Transverse Mercator (UTM) projection and grid system, Zone 17, North American Datum 1983 (NAD83). The files are available on 1 DVD. $25.00.

Precambrian Geology of Cavendish Township, Central Metasedimentary Belt, Grenville Province; by R.M. Easton, 141p. Accompanied by Preliminary Map P.3605. $47.00.

Miscellaneous Release—Data 295
Lithogeochemistry of the Dog Lake Granite Chain, Northwestern Ontario; by B. Kuzmich, P. Hollings and D.A. Campbell. This release contains whole-rock geochemical data for the granitic intrusions of the Dog Lake granite chain in the Quetico Basin, north of Thunder Bay, northwestern Ontario. A document (portable document format (.pdf) file) provides a general description of the units sampled, their petrography and geochemistry as well as an interpretation of the data. The results of the geochemical analyses are provided as a Microsoft® Excel® 2003 (.xls) file. The data are available on 1 CD. $20.00.

Sedimentary Geoscience

Open File Report 6259
Results of Regional Till Sampling in the Cobalt–New Liskeard–Englehart Areas, Northern Ontario; by C. Gao. Digital data available as Miscellaneous Release—Data 284 (see below). 87p. $26.00.

Miscellaneous Release—Data 284
Till Sample and Indicator Mineral Data for the Cobalt, New Liskeard and Englehart Areas, Northern Ontario; by C. Gao. This release presents the results of a regional till sampling and surficial mapping project undertaken in the Cobalt, New Liskeard and Englehart areas in northern Ontario between 2007 and 2009. The results consist of geochemical and compositional data of kimberlite indicator minerals (KIMs), metamorphic/magmatic massive sulphide indicator minerals (MMSIM®*) and gold grains recovered from till and glaciofluvial sand and gravel samples. The data are being released in conjunction with Open File Report 6259, available separately. Files in this release contain information on sample site locations; a list of abbreviations; sample processing data; KIMs picked and picking remarks; microprobe analyses of KIMs; gold grain data; MMSIM® data; pebble lithology data; and adjusted KIM and MMSIM® results. The data are available on 1 CD. $20.00.

Miscellaneous Release—Data 297
Aggregate Test Results for Various Rock Types in Ontario; by D.J. Rowell and J.E.P. Dodge. These data represent the results of “standard” aggregate testing collected and collated by the Ontario Geological Survey (OGS) over many years and at locations throughout various parts of northern, central and southern Ontario. Most of the bedrock test results have been published in a variety of OGS reports; however, some bedrock test results have not been released previously and are being released for the first time through this Miscellaneous Release—Data (MRD). The data and supporting information are provided as Microsoft® Excel® 2003 (.xls) and portable document format (.pdf) files, and as Google Earth™ mapping service (.kml, .kmz) depicting sample locations and other information. The data are available on 1 CD. $20.00.
