Niblack, Moira Sound

by | Nov 25, 2020

Niblack is a historical mining community at the head of Niblack Anchorage, an estuary that extends west for 2.5 miles (4 km) off Moira Sound, on the southeast coast of Prince of Wales Island, about 28 miles (45 km) southwest of Ketchikan and 28 miles (45 km) southeast of Hydaburg, Alaska. Niblack was named by Lieutenant Commander Richardson Clover in 1885 for Ensign Albert Parker Niblack of the U.S. Navy who was a crew member on Carlile P. PattersonIn 1901, a post office was established in Niblack but was transferred to Ketchikan in 1909.

Niblack is an ore deposit that consists of 2.6 million tons of copper, zinc, gold, and silver. Beginning in the mid-1970s, a succession of at least 11 companies have extensively explored several prospects in the Niblack area. The ore bodies of mineralization that received the most attention are near the Lookout and Trio prospects. The various companies have also done considerable surface mapping and sampling and carried out numerous geochemical and geophysical surveys. The current Niblack Project is an underground mine being developed by Heatherdale Resources Limited that holds 6,200 acres of federal and state mineral claims.

Since at least 2005, most of the work has been concentrated on mineralization near the old Lookout prospect. The Lookout prospect is at an elevation of about 1,800 feet (549 m) and was known before World War I. In 2008, an exploration drift of 2,886 feet (880 m) was completed by Heatherdale Resources to test the deposit at depth and much of the drilling since then has been from this drift. As of November 4, 2011, 343 holes have been drilled on the Lookout and Trio deposits. Read more here and here. Explore more of Niblack here:

About the background graphic

This ‘warming stripe’ graphic is a visual representation of the change in global temperature from 1850 (top) to 2019 (bottom). Each stripe represents the average global temperature for one year. The average temperature from 1971-2000 is set as the boundary between blue and red. The colour scale goes from -0.7°C to +0.7°C. The data are from the UK Met Office HadCRUT4.6 dataset.
