Kimberlites in Alberta-A Major New Diamond-bearing Kimberlite Province

The Buffalo Head Hills region is located approximately 350 kilometres northwest of the city of Edmonton in northcentral Alberta (Figure 1). The Alberta diamond joint venture consisting of Ashton Mining of Canada Inc., Alberta Energy Company Ltd and Pure Gold Minerals Inc. began exploring for kimberlites in the Buffalo Head Hills region in late 1996. At the time, the Mountain Lake diatreme, located 200 kilometres to the southwest, was the only reported kimberlitic rock in Alberta (Leckie et al., 1997, Figure 1). Exploration efforts since 1996 have successfully identified a new diamondiferous kimberlite province in Canada.
