The value of mineral production in Alaska for 1990 jumped to US$534 million in 1990, up substantially from the US$277 million reported in 1989. The increase was primarily caused by a jump in base metal production from the Greens Creek and Red Dog mines operated by Kennecott and Cominco (TSE), respectively.
The value of gold production for the year remained fairly constant at about US$89 million.
Exploration expenditures for 1990 increased to US$56.9 million from US$47 million in 1989. About $52 million, or 90% of the expenditures, were aimed at gold exploration.
