The USGS Mineral Resources Data System (MRDS) — ~300,000 mines, prospects, occurrences and processing plants worldwide, with commodity, deposit type, development status, production history and bibliography.

Tools

• mrdata_search_deposits(bbox?, name_contains?, commodity?, limit?) — sites with deposit id, name, development status, coordinates and commodity codes.
• mrdata_deposit(dep_id, sections?) — the full record for one deposit.
• mrdata_commodities(bbox?, sample_size?) — commodity site counts for an area, or the code reference list.

Auth

Keyless.

Data sources

• https://mrdata.usgs.gov/services/wfs/mrds — OGC WFS point layer (search).
• https://mrdata.usgs.gov/mrds/json/<dep_id> — full record for one deposit.

Things the next person would otherwise rediscover:

• The WFS speaks GML only. outputformat=geojson and application/json are both rejected by name; only GML 2.1.2 and GML 3.1.1 are advertised.
• Use version=1.0.0 for bbox queries. WFS 1.1.0 flips EPSG:4326 to lat,lon and a 1.0.0-style bbox then returns ZERO features with no error at all.
• PropertyIsEqualTo on dep_id fails server-side. PropertyIsLike with no wildcard works, and is what exact lookup uses.
• The per-deposit JSON is a PATH, /mrds/json/<dep_id>. The query-parameter form answers HTTP 400 with an empty body.
• Commodity codes are not element symbols. MRDS codes non-metals with three letters (SDG sand and gravel, STN stone, CLY clay, LST limestone) and qualifies them with a suffix (STN_C crushed stone, PGE_PT platinum). SDG is the single commonest code in the western US — a two-letter-symbol table leaves it, and most of the database, unnamed.
