Sinossi
Excerpt from Mineral Resources of Alaska: Report on Progress of Investigations in 1907
The output of Alaska includes the metals gold, silver, copper, lead, and tin, and the nonmetallic minerals coal, petroleum, gypsum, and marble. In addition to these, iron, tungsten, antimony, quick silver, and graphite deposits have been found, which may prove to have commercial importance.
Gold is both the most widely distributed and by far the most im portant of the minerals yet developed. It occurs in combination with silver and other impurities in the alluvium. The auriferous lodes include both free-milling and concentrating ores. Tellurides have been found, but not in commercial quantities. A few grains of platinum have been found in some of the gold placers, but nowhere in commercial quantities. Silver occurs in association with the gold, both in the lodes and placers. Silver-bearing galena deposits are widely distributed, but have been but little developed.
