Exploration 1986 - Alaska

Exploration expenditures in Alaska last year amounted to $8.9 million. This was comparable to 1985's $9.1 million. Development expenditures dropped 29%, $24.3 million in 1986 vs. $34.1 million in 1985. The exploration industry is restructuring and stabilizing after the loss of major mineral firms during the last few years. These included Anaconda Minerals, Asarco, Hecla Mining, Enserch Exploration, Phillips Minerals Division, Exxon Minerals, Noranda Inc., General Crude, Mohawk Oil & Gas, Inspiration Development, Teton Exploration, and St. Joe Minerals Division. Some of these companies were mineral subsidiaries of oil companies and were either dissolved or redirected to programs outside of Alaska. However, recent entry exploration firms include Echo Bay Mines Ltd., Long Lac Minerals, and Exvenco. They are busy evaluating prospects and mineral developments in the southeastern panhandle. In the 1970s, about $254 million was spent on Alaska mineral exploration. Of this, about 5% ($12 million) was for nonmetallics and coal, about 26% was directed at precious metals ($66 million) mainly gold, and 69% ($175.3 million) for the base metals zinc, copper, molybdenum, tin, tungsten, and nickel. Since the early 1980s, trends have reversed. Of the nearly $196.3 million spent from 1981-1986, 48% has been for precious metals ($94.3 million) and 40% on nonmetallics and coal. In the last two years, nearly 70% of the Alaskan exploration dollar has been spent in search of precious metals. Three gold skarns were explored during the year - the Nixon Fork project in western Alaska (Battle Mountain Mining Co.), the Nebesna and Rambler lodes of the northern Wrangell Mountains (Nebesna Mining Partners), and the Zackley project near Paxson in southcentral Alaska (Nerco Minerals). Nearly 7.6 km (25,000 ft) of diamond and rotary drilling were conducted on these three properties. Aspen Exploration announced that significant gold mineralization was found under the Nome coastal plain in western Alaska.
