Survey Description
In July and August 1998, a high-density lake sediment and water survey was carried out in the Garden Lake-Obonga Lake area, northwestern Ontario.
| Sample Type | Number of Sites | OGS Open File Report |
| Lake sediment | 1951 | OFR6009 |
| Lake water | 2138 |
The data are published in Ontario Geological Survey (OGS) Miscellaneous Release Data, MRD051.
As part of Operation Treasure Hunt, the samples were reanalyzed for Au and PGEs. The data are published in Ontario Geological Survey OFR6028 and MRD057.
The data are also part of a compilation database, Lake Geochemistry of Ontario – 2019.
