  <dc:description>&lt;html&gt;&lt;body&gt;&lt;p&gt;U.S. Geological Survey research, in collaboration with Montana Technical University and Montana Bureau of Geology and Mines, is providing key critical mineral information that may have potential for critical mineral production of several mining districts in the Boulder Batholith region, to better understand the abundance and distribution of natural resources within this region. Continued research can be used to show the potential for previously undiscovered critical mineral resources in southwestern Montana and in other parts of the United States.&lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</dc:description>
