Summary

This report and digital data release presents 209 new geochemical analyses on historic U.S. Bureau of Mines (USBM) samples, including 90 rock, 9 stream sediment, 14 soil, and 96 heavy mineral concentrate (pan concentrate) samples. These samples were originally collected by the USBM as part of their search for radioactive mineral deposits in the northern Darby Mountains, eastern Seward Peninsula, Alaska Historic USBM sample materials were retrieved by DGGS from the DGGS Geologic Materials Center (GMC), where the USBM samples were transferred as part of the federally funded Minerals Data and Information Rescue in Alaska (MDIRA) program in the late 1990s and early 2000s. The text and analytical data and tables associated with this report [...]

Purpose

The State of Alaska's Strategic and Critical Minerals (SCM) Assessment project, a state-funded Capital Improvement Project (CIP), designed to evaluate Alaska's statewide potential for SCM resources. The SCM Assessment project is being implemented by the Alaska Division of Geological & Geophysical Surveys (DGGS), and involves obtaining new airborne-geophysical, geological, and geochemical data. For the geochemical part of the SCM Assessment project, thousands of historic geochemical samples from the DGGS, U.S. Geological Survey, and U.S. Bureau of Mines (USBM) archives are being re-analyzed by DGGS using modern, quantitative, geochemical-analytical methods. The objective is to update the State of Alaska's statewide digital geochemical database in order to more clearly identify areas with SCM potential.
