Who updated the resource estimate for the Donlin Creek gold deposit?
The updated resource estimate for the Donlin Creek gold deposit was prepared in January 2002 by MRDI of Vancouver, BC. MRDI’s parent company is an independent engineering firm with more than 40 years of experience in developing and building mines in Alaska and the Canadian North. This updated estimate incorporates all data obtained from the sampling and drilling programs on the project through November 2001. Why were cut-off grades of 3.5 g/t, 2.5 g/t and 1.5 g/t of gold chosen? Cut-off grades of 3.5 g/t, 2.5 g/t and 1.5 g/t gold were selected by AMEC/MRDI and NovaGold as representative of the large-scale open pit mining operations that would be potentially economic for a range of gold prices from US$250 to US$300 to US$350 per ounce of gold.
