Survey Description

36 B-horizon soil and 56 till samples were collected in the Baker Zone in the Lac des Iles mine area in 2000.  Two sampling lines, 50 m apart were run parallel to ice flow direction and extended up and down-ice from known mineralization.  The data are published in Ontario Geological Survey Open File Report 6054.

Data Description:

Paper report with data lists.  Digital data available separately as MRD-71 (Miscellaneous Release-Data 71).

Quantities Analysed:

<0.177 mm fraction of humus and <0.063 mm fraction of till by ICP-AES for 25 elements; by ICP-AES-FA for Au, Pd, and Pt; and ICP-MS for 51 elements.

Geochem Maps Available:

Proportional symbol maps show dispersal of selected elements.

Other Analyses:

Heavy mineral concentrate from 77 till samples for gold grain counts and metamorphic or magmatic massive sulphide and kimberlite indicator minerals; pebble lithologies for 77 till samples.
