Survey Description
Till sampling was carried out in the Darrol Lake area, south of Ruttan Mine, Manitoba, to determine the potential for gold mineralization:
| Year | Number of Samples |
| 1987 | 23 (19 till, 4 littoral sand) |
| 1988 | 24 till |
The samples were processed for heavy minerals, including gold. A summary of the work can be found in Manitoba Energy and Mines, Report of Field Activities, 1988.
The data are published in Manitoba Agriculture and Resource Development, Data Repository Item DRI2020019 and are part of three compilation open files, OF2020-2, OF2020-5 and OF2020-6.
