Till Ontario 1992

Till sampling survey, NTS 52N,K in northwestern Ontario, 1992.  


Geological Survey of Canada, Terrain Sciences Division

Survey Description

278 till samples and 38 sand samples were collected in the Red Lake-Confederation Lake area, northwestern Ontario in 1992. The data are published in GSC Open File 3038.

Data Description: Paper report with diskette.

Quantities Analysed: <0.063 mm fraction by ICP-AES after HNO3-HCl digestion for 22 elements; by fire assay/DCP for Au, Pt, and Pd; by INAA for 30 elements. Non-ferromagnetic heavy mineral fraction by INAA for 35 elements.

Geochem Plots Available: Proportional symbol maps show dispersal of elements.

Other Analyses: Heavy mineral concentrate for gold grains, kimberlite indicator minerals, and point counts; pebble lithologies (5.6-16 mm).

Project History

1991-1995 Northwestern Ontario till sampling survey carried out in 1991-1992.
  The project was designed to investigate the stratigraphy, sedimentology, composition and source of glacial sediments, especially till, in areas of potential bedrock mineralization. The Red Lake-Woman Lake-Confederation Lake area was chosen because producing gold mines and former base metal mines are located in the area and there is potential for further mining development. Glacial sediment covers large parts of the area and conceals promising targets. Drift prospecting in this area will aid exploration. The data are published in GSC Open Files 2583 and 3038. The till data have also been released as part of a geoscience compilation for the area in GSC Open File 3751.
