Till Ontario 1993

Till sampling survey NTS 42A, northeastern Ontario, 1993-1996.  


Geological Survey of Canada, Terrain Sciences Division

Survey Description

Till samples were collected around 5 Archean lode gold deposits in the Timmins-Matheson area, northeastern Ontario between 1993 and 1996. The deposits studied were Davidson-Tisdale Mine, Bell Creek Mine, Pamour Mine, Nighthawk Mine and Hislop pit. The data are published in Geological Survey of Canada Open File 3707.

Data Description: Paper report with data lists.

Quantities Analysed: <0.063 mm and <1.7 mm heavy mineral fraction by INAA for 35 elements and ICP-ES after aqua regia digestion for 32 elements.

Other Analyses: Heavy mineral concentrate for gold grain counts; pebble lithologies; carbonate (<0.063 mm (Chittick)); grain size.

Project History

1993-1999 Northeastern Ontario till sampling survey carried out in 1993-1996.
  Closely-spaced till samples were collected around 5 known Archean lode gold deposits in 1993-1996. The objectives of the project were 1) to document the nature of gold grain, multi-element geochemical and pebble lithological signatures in till associated with the gold deposits; 2) to demonstrate the use of till gold grain and geochemical methods in detecting gold mineralization in the Timmins area; 3) to compare the effectiveness of different size fractions of till for gold exploration; and 4) to examine the natural geochemical signatures in till around gold deposits from an environmental perspective. The data are published in Geological Survey of Canada Open File 3707.
