In Windham bay, a cluster of mineral claim holdings were consolidated in the 1920s; the jensen mine was the most productive of these, producing about 50 ounces of gold. Several aerial tramways, thousands of feet long, connected various adits and mills. 15 Ketchikan district edit Alaska mining District Approximately 58,000 ounces of lode gold and 4000 ounces of placer gold have come from the ketchikan district, consisting of Dall, prince of Wales, revillagigedo, and smaller islands, as well some mainland, in the southernmost-part of Alaska. 13 Numerous historical lode mines and prospects for base metals, uranium, rare earth elements (ree's iron, and platinum group elements (pge's as well as gold exist in the ketchikan district.

Major production came from underground lode mines exploiting gold-in-quartz veins. Apex-El Nido mine edit The Apex-El Nido produced perhaps 50,000 ounces of gold from a mile of underground workings exploiting polymetallic quartz veins. 14 Hirst-Chichagof mine edit From 1922 to 1933 the essay hirst-Chichagof produced 133,000 ounces of gold and 33,000 ounces of silver from polymetallic quartz veins assaying nearly 1 ounce of gold per ton.

There were several miles of workings on 5 levels. Six shafts reached a maximum of 2,750 feet (840 m) below sea level. Between 19everal thousand feet of new workings were dug, and engineering and environmental studies were done, but the project was abandoned. 14 Petersburg-Sumdum district edit 15,000 ounces of gold from placers, came from the petersburg-Sumdum district which consists of; Zarembo, etolin, and Wrangell Islands, and the mainland between the juneau and Ketchikan districts. Many small lode deposits were located in the late 1890s and early 1900s.

Outside of the porcupine basin only a few other creeks Glacier, nugget and Cottonwood produced significant gold. The area around reid Inlet, in modern Glacier bay national Park and Preserve, hosted several hard rock gold prospects, including the leroy mine, which exploited quartz veins for about 10,000 ounces of gold production. The district, which includes skagway and haines, is bordered to the north and east by canada.
