Abstract The report summarizes findings by the Bureau of Mines during the second year of the Juneau Mining District study. Fifty mines, prospects, and occurrences were examined, and 638 samples were collected for analysis. Metallurgical samples were collected from seven deposits, and preliminary tests of cyanide amenability have been completed for five of these. The simultaneous discovery by the Bureau and private industry of gold-bearing quartz veins cutting diorite gneiss recently exposed by the retreat of the Herbert Glacier is the most notable find in 1986, yielding gold values up to 7 oz/st.
