The mineral map groups its 60 entries into families, with tiles shaded by net import reliance and links to individual fact sheets. Policy and funding sections include source links, while funding calls can be filtered by mineral or agency; the awards section identifies contracts and grants from USAspending. Separate pages explain the relevance rubric, how AI tags are checked, and what the site does not cover.
