## History

Platinum was named in the 1930s due to the platinum ore found in the area. The site was a mining boomtown by 1937 boasting a roadhouse, two trading posts and a population of 50. A post office had been established in 1935. An earlier Inuit village called Arviq had been abandoned. The town was incorporated as a city in 1975.
Ray Petersen Flying Service was awarded the exclusive contract in 1937 to fly for the Goodnews Bay platinum and iridium mine, hauling miners and company supplies out of his base at Bethel, Alaska.
During World War II, the Alaska Territorial Guard served to safeguard it against Japanese attack as it was the only source of the strategic metal platinum in the Western Hemisphere.

## Geology

In 1926, Walter Smith, an Eskimo, discovered what he thought was "white gold" at the mouth of Fox Gulch, a tributary of Platinum Creek. Samples sent to the United States Bureau of Mines in Fairbanks determined it was actually platinum. In 1928, Charles Thorsen discovered platinum in Clara Creek, while Edward St. Clair discovered platinum in Squirrel Creek. Consolidation of the subsequent mining claims resulted in Goodnews Bay Mining Co. and Clara Creek Mining Co. becoming the major operators mining these placer deposits containing 60 per cent platinum and 22 percent iridium. The largest nugget was found on Squirrel Creek and weighed 1.5 ounces. These placers are found in the drainage east of Red Mountain, which is composed of dunite. However, platinum has not been found on the mountain. Goodnews Bay Mining Co. started operating a dragline excavator on Squirrel Creek on August 11, 1934, and on Platinum Creek and Fox Gulch in 1937. The company started operations with a dredge in Nov. 1937. The Clara Creek Mining Co. started mining operations on Clara Creek in 1936. A total of 3000 ounces of platinum metals were recovered from all mining operations between 1927 and 1934, and 18,000 ounces between 1934 and 1937.
