Mcs Country Comparison
mcs_country_comparisonRead-onlyIdempotent
World mine/plant PRODUCTION (prior-year actual + current-year estimate) and RESERVES, by country, for one mineral commodity from the USGS Mineral Commodity Summaries — e.g. "which countries hold lithium reserves" or "China vs. Australia rare-earth production". Covers 75 of the 85 commodities MCS tracks (the other 10 — mostly scrap/slag/crushed-stone categories USGS tracks only domestically — return found:false with a pointer to mcs_commodity_data instead). Optional countries filter (comma-separated or array) narrows to named countries; rows are otherwise sorted by current reserves, descending. Keyless.
