Greenland has seen several campaigns of diamond exploration since the early 1970s. Inspired by reports of kimberlite dykes at several locations in southern West Greenland, an exploration company investigated occurrences in the Pyramidefjeld area north of Ivittuut and recovered two microdiamonds and one macrodiamond from kimberlitic samples. Early regional kimberlite prospecting covering large parts of West Greenland resulted in two microdiamonds extracted from bulk stream sediment samples from the broad Sarfartoq valley.
Field campaigns from 1994 onwards have mostly been dedicated to regional till and stream sediment sampling programmes with a view to locate kimberlite indicator minerals. Next followed airborne magnetic and electromagnetic surveys and drilling on frozen lakes for possible diatremes.
