Survey Description

626 samples were collected in the Upper Attawapiskat and Ekwan River area, northern Ontario in 1996. 82 were till, 510 were modern alluvium and 34 were glaciofluvial sediments. The data are published in Ontario Geological Survey Open File Report 6097.

Data Description: Paper report; digital data released as compressed ASCII and Excel files on diskette as MRD-109 (Miscellaneous Release-Data 109).

Quantities Analysed: <0.063 mm fraction by INAA for 35 elements; by ICP-OES after a total (HNO3-HClO4-HF-HCl) digestion for 19 elements.

Geochem Plots Available: Proportional symbol maps showing the dispersal of elements, based on data -80 mesh till and -60 mesh non magnetic tabled concentrates.

Other Analyses: Heavy mineral processing (at Consorminex) for kimberlite indicator minerals (KIMs).

Project History

1996-2003 Northern Ontario Spider 3 survey carried out in 1996.
  In the summer of 1996, a regional helicopter-supported heavy mineral-geochemical survey was carried out over a 13 000 km2 region of northern Ontario. This survey utilized heavy mineral/geochemical sampling combined with airborne geophysical surveys to delineate areas favourable for kimberlite exploration. This project is a joint venture between the Ontario Geological Survey and the private sector (KWG Resources) and is intended to provide the public with new information that will augment past and future projects carried out by both the OGS and the private sector. The data are published in Ontario Geological Survey Open File Report 6097.
