About this source
USGS MRDS + USMIN — global mineral deposits + US mine-feature points (no auth). Upstream (MapServer WFS 2.0.0): - /services/wfs/mrds — ms:mrds (~304K worldwide deposits) - /services/wfs/usmin — ms:points + ms:polygons (US only) Rich per-record JSON: /mrds/json/{dep_id} returns 26+ subtables (commodities, materials, ages, ore body, production, references, rocks). Filters: commodity (CU/AU/AG/FE/LI/U/REE/PGE…), country (FIPS), US state, dev_stat (Past Producer/Producer/Occurrence/Prospect/Plant/Raw Prospect), bbox. §0 quirks: CQL_FILTER silently ignored by MapServer — handler emits OGC FILTER= XML (fes:Filter). fips_code stored with literal "f" prefix (fCI / f06065). code_list space-separated with leading space.

Technical detail for developers: parameters, pagination, units, and freshness per method.
searchDeposits
readMRDS deposits worldwide. Filter commodity (2-letter code), country (FIPS), US state, dev_stat, bbox.
commodity is matched against code_list with PropertyIsLike "%CODE%".
getDepositById
readFull deposit record — 26+ subtables (commodities, materials, ages, ore body, references).
Source: mrdata.usgs.gov/mrds/json/{dep_id}. GeoJSON Feature.
searchByBbox
readSpatial-only deposit search. bbox is [minX, minY, maxX, maxY] in WGS84.
Skips XML filter; uses WFS BBOX URL shortcut for speed.
searchUsminFeatures
readUS conterminous mine features (Mine Shaft / Adit / Prospect / Tailings). Requires state.
USMIN does not cover Alaska, Hawaii, PR, or international.
countDeposits
readCount deposits via WFS resultType=hits. Slice by commodity / country / state.
Defaults to lithium in Nevada (disclosed). State: US postal code/two-digit FIPS.
getServiceInfo
readEndpoints, layer fields, pagination conventions, distinct enum values, upstream quirks.
