Geochemical trace-element and rare-earth element data from stream-sediment and pan-concentrate samples collected in 2011 in the Melozitna mining district, Tanana and Melozitna quadrangles, interior Alaska

Mineral-resources personnel from the Alaska Division of Geological & Geophysical Surveys conducted reconnaissance stream-sediment and pan-concentrate sampling in the Melozitna Mining District, Tanana and Melozitna quadrangles, from July 25 to August 13, 2011. This helicopter-supported sampling project was part of a statewide assessment of Alaska's potential for rare-earth element (REE) mineralization, and was funded by the Rare Earth Elements and Strategic Minerals Assessment capital improvement project. During this field project, 32 stream sediment and 28 heavy-mineral pan concentrate samples were collected for geochemical analysis (geochemical trace elements and rare earth elements). An additional historic U.S. Bureau of Mines sample from the area was also analyzed as part of this report. Highlights of the DGGS sampling project include documenting new gold-bearing drainages and identifying several samples with high REE values.
