(requires an Internet connection)
In the summer of 1996, a total of 626 samples were collected in the Spider 3 survey area, in the region of the Upper Attawapiskat and Ekwan Rivers, northern Ontario. Eighty-two samples were till, 510 were modern alluvium and 34 were glaciofluvial sediments. The details of the survey are published in Ontario Geological Survey Open File Report 6097 and the data (geochemistry + KIM) in Miscellaneous Release-Data 109.
