Survey Description


In August 1996, a high-density lake sediment and water survey was carried out in the Hemlo-Heron Bay-White Lake area, northwestern Ontario.  Lake sediment and water amples were collected at 211 sites for an average density of 1 sample per 2 km2.

The data are published in Ontario Geological Survey Open File Report OFR5968 and Miscellaneous Release-Data, MRD035.

As part of Operation Treasure Hunt, the samples were reanalyzed for Au and PGEs.  The data are published in Ontario Geological Survey OFR6036 and MRD065.

The data are also part of a compilation database, Lake Geochemistry of Ontario – 2019.

The geographic extent of the survey is defined by the following polygons:

  • Covers most of NTS 42C/13 (White Lake) and parts of 42C/12 (Cedar Lake), 42D/9 (Marathon) and 42D/16 (Goodchild Lake) in the Hemlo-Heron Bay-White Lake area, northwestern Ontario.  It is bounded to the west by Lake Superior .  The eastern edge of the study area is located just west of White Lake.
