Gravimetric analyses of Peruvian placer gold, obtained in the form of irregular grains, showed a gold content exceeding 90% with silver as the other major component. Iron was found as a frequent minor component and may be in the form of either disseminated hematite or magnetite. These specimans did not have weighable amounts of copper. It is suggested that iron occurs in Peruvian placer gold in higher proportion than in native gold from other regions of South America.
