27 till samples from Contwoyto Lake (NTS 76E South), were processed by Canamera Geological Services, North Vancouver, BC. Samples were screened into the 0.25 – 0.5 mm grain size fraction and separated magnetically with a Permaroll separator and for heavy mineral fractions with a Magstream separator. The 27 samples were then sent to Diamond Indicator Processing of Thunder Bay, Ontario where samples were separated for magnetite and mica. The < 0.25 mm fraction was sent to ODM processing for gold grain recovery. Samples were collected in 1994 and processed in 1995. (These are put together under one process/package as the information from each lab is combined in the appendix).
These data are published in GSC Open File 3386.
