Gold mining in Alaska, a state of the United States, has been a major industry and impetus for exploration and settlement since a few years after the United States acquired the territory from Russia. Russian explorers discovered placer gold in the Kenai River in 1848, but no gold was produced. Gold mining started in 1870 from placers southeast of Juneau, Alaska.

Loed near the mine shaft, the vein is encountered at level 45 meters. Gold bearing mineralization appears in a broad brecciated zone consisting of alternating silicified, pyritized and sericitized diorite bands, and thin milky quartz bands. The distribution of the gold contents is erratic although gold values increase at a depth.

This can be an indior of gold. Iron Staining & Gossans: Not all veins produce much quartz – gold bearing veins can consist of calcite or mostly sulfides – which often weather into iron stained spots when the pyrites convert to iron oxides. Large amounts of iron oxides like hematite, magnetite and ironstone can be favorable indiors.
