Quirks

site_name blank for 1255/1635 sites; deposit_name falls back to the location field
global geography the US-centric MRDS 2016 freeze under-covers (US is only 112 of 1635 sites here)
resources is curator free-text; first '<N> Mt ore @ <X>% P2O5' figure parsed (351/576 sites), rest stay occurrence-only

Emits DepositOccurrence (per site x co-commodity) + DepositResource (phosphate ore+%P2O5). Co-commodity fan-out adds net-new U/Nb/REE/F/Ti/V occurrences.
