Discover and download a USGS mineral-resource dataset (e.g., SaMiRA, USMIN) via the ScienceBase catalog

Steps
Search data.usgs.gov (ScienceBase) for the target dataset by name, e.g. "BLM LR2000 mining claim authorizations" or "USMIN Mineral Deposit Database."
Open the ScienceBase item page to confirm licensing, spatial extent, and attached data files (shapefiles, CSV, geodatabase).
Use the ScienceBase REST item API (JSON) to programmatically resolve an item ID to its list of downloadable file URLs instead of scraping the HTML page.
Download the attached files directly via their stable ScienceBase file URLs.
Check the item's linked metadata record for field definitions before joining the dataset to other mining data sources.
Known gotchas
ScienceBase hosts data catalogued from many separate USGS programs; item structure (single file vs. many child items) varies by dataset, so don't assume a fixed schema across items.
Some items link out to a source agency's own system (e.g., BLM) for the authoritative live data — the ScienceBase copy may be a periodic snapshot, not the live dataset.
