    This report presents the results of site specific sampling in the Goodnews Bay Mining District in Approximately 70% of the mineral deposits in the district are located in two areas: Slate- Wattamuse Creek and Red Mountain. Placer deposits with high mineral development potential are located on Wattamuse and Cascade Creeks.

    scattered places throughout Alaska during the early years of this century. About 96 percent of the reported Alaskan production of platinum-group metals was from the placers of Salmon River and its headwater tributaries about 15 miles south of Goodnews Bay on the west coast of Alaska. Table Estimated production of platinum-group metals. 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 , but no gold was produced. Gold mining started in from placers southeast of Juneau, Alaska.

With respect to the geology, the Goodnews Bay placers, which actually were won from the Salmon River drainage and its tributaries, produced on the order of , ounces,” Foley says.

Platinum-group elements in magnetic concentrates from the Goodnews Bay District, Alaska. Platinum-group elements in magnetic concentrates from the Goodnews Bay district, Alaska. [Sam Rosenblum; Geological Survey (U.S.)] -- Platinum-group elements (PGE) occur in magnetic concentrates as discrete mineral grains, as inclusions in magnetite, and as diffused atoms in the magnetite lattice.

INTRODUCTION There are six platinum group elements (PGE): ruthenium (Ru), rhodium (Rh), palladium (Pd), osmium (Os), iridium (Ir) and platinum (Pt). USGS The Goodnews Bay District of Alaska has produced thousand of ounces of Platinum In placer deposits.

This publication discusses the various deposits and Creeks that produce the platinum, along with production statistics and more. Goodnews Bay, southwest Alaska, is known for platinum (Pt) reserve that extends offshore in the Bering Sea. 2 Mertie, J.

The Goodnews Bay district is an indefinite region that includes all the country contiguous to Goodnews Bay. The part of the district described in this report is a small area lying south of Goodnews Bay which, on the accompanying map, is designated Platinum and vicinity.

This small area is the site of the platinum deposits that constitute the. Bering Sea coast of Alaska. Goodnews Bay indents the mainland coast of western Alaska just south of the mouth of the Kuskokwim River.

The Goodnews Bay Mining Company and its predecessor, Northland Development Company, have been mining a placer deposit of platinum metals in this remote area since Goodnews Bay, from which the Mining Company.

From abstract: Platinum placers were discovered in in a small area south of Goodnews Bay, in southwestern Alaska. Beginning inthe placers were worked for 7 years by small-scale mining methods; in later years dragline excavators and a dredge were utilized.

Magnetic Concentrates from the Goodnews Bay District, Alaska By Sam Rosenblum, R.

Carlson, J. Nishi, and W. Overstreet Abstract Platinum-group elements (PGE) occur in fer- romagnetic concentrates from placer deposits in the Goodnews Bay. Throughout history, gold, silver and the platinum group elements have occupied a position of considerable social and economic importance.

Indeed, the analytical chemistry of these elements. Platinum is located on the Bering Sea coast, below Red Mountain on the south spit of Goodnews Bay. It lies 11 miles from Goodnews Bay and miles southwest of Bethel.

It is miles west of Anchorage. It lies at approximately 59° 00' N Latitude, ° 49' W Longitude (Sec. 32, TS, RW, Seward Meridian).
