The DOIG anomaly is centred on a gravel pit having anomalous Ag values approximately 1 kilometre east of Doig River, 70 kilometres northeast of Fort St. John, B.C.

The area was initially explored by Highplain Exploration Ltd. in 1969 and 1970, based on the discovery of highly limonitic sands and shales with a number of massive pyrite - pyrrhotite pebbles and some lenses of white volcanic ash. Eighty-three soil samples were collected over the area with the highest value of 2.2 parts per million. Ag in one of the small lenses of volcanic ash, versus the 0.4 - 0.8 parts per million background (Assessment Report 02910).

In 2002 Diamant Resources Ltd. obtained two glaciofluvial gravel pit samples on either side of the Doig River west of the anomalous area. The primary objective of the heavy mineral sampling program was to generate possible new kimberlitic indicator mineral anomalies. Results have not been published (Assessment Report 27000).
