Breccia pipe uranium - USGS fact sheet

The USGS has released a fact sheet on breccia pipe uranium mining in northern Arizona, based on the results in their 2009 report.
The USGS studies provide estimates of uranium resources affected by the possible land withdrawal, examine the effects of previous breccia-pipe mining, summarize water-chemistry data for streams and springs, and investigate potential biological pathways of exposure to uranium and associated contaminants.
BLM will release the draft EIS regarding withdrawal of a 1 million acres of federal lands from exploration and mining, later this month for public comment.
