Reserves bubbles
Each bubble sits at the country centroid; its radius is proportional to √(USGS-reported reserves) for the selected metal. Source: USGS Mineral Commodity Summaries 2026.
Storage — Tier 1 (warranted)
Exchange-warranted vaults: LME-approved warehouse cities, LBMA London bullion vaults, COMEX-approved NY metro vaults and SHFE bonded Shanghai. Public stock figures available.
Storage — Tier 2 / 3 (regional + commercial)
Tier 2 — exchange-approved regional vaults (SGE, TOCOM, MCX, DGCX, Borsa Istanbul). Tier 3 — commercial vaults (Brink's, Loomis, Malca-Amit, G4S, Freeports). No public stocks; link-only.
Storage — Tier 4 (refiners) Tier 5 (CB gold)
Tier 4 — LBMA Good Delivery refiners with on-site vaults (Switzerland's quadriumvirate, Heraeus, Umicore, mints). Tier 5 — sovereign central-bank gold reserves (Fed NY, BoE, Bundesbank, …).
Exchanges
The eleven physical-metals trading venues that publish reference prices: LME, CME/COMEX, SHFE, SGE, TOCOM, MCX, HKEX, DGCX, Borsa Istanbul, MOEX and B3.
Producers (HQ)
Curated list of top global mining & metallurgy producers, plotted at the corporate headquarters city (not mine sites). Filtered by the metal selector — only HQs that produce the selected metal are shown. Source: each company's own corporate disclosures, aggregated in /producers/.
Mines & Smelters
Curated 30 top-tier physical assets — mines (brown triangle) and smelters/refineries (brown square) — plotted at the asset's geographic location. Filtered by the metal selector. Source: each entry links to the operator's official asset page (BHP, Rio Tinto, Codelco, Freeport, Vale, Polyus, Nornickel, Aurubis, Rusal, South32, Anglo American Platinum, Talison, Albemarle, SQM, Arcadium, Navoi, Barrick, South32, PT Timah, etc.).
Ports
20 major commodity ports plotted at their official location, with annual tonnage from port-authority reports (Pilbara Ports, Port of Rotterdam, Antwerp-Bruges, Shanghai SIPG, MPA Singapore, Transnet, Vale terminals, etc.). Each popup links to the operator's primary source.
Sea Routes
Top dry-bulk and concentrate routes for metals (iron ore, copper concentrate, bauxite) — illustrative polylines drawn along established commercial shipping lanes, not navigational. Volume estimates and route significance cite UNCTAD Review of Maritime Transport 2024 and producer disclosures.
Rail Corridors
Six metals-relevant rail freight corridors at their published line geometry — Trans-Siberian, BAM, China–Europe Rail Express (CREX), Middle Corridor (TITR), INSTC and the Kiruna–Narvik Iron Ore Line (Malmbanan). Each polyline is illustrative (not navigational) and links to the operator (RZD, LKAB/Trafikverket) or the multilateral source (UIC, TITR consortium, UN ESCAP, World Bank ITF). Gauge breaks and ferry legs called out where relevant.
Refineries
50 flagship LBMA Good Delivery and LPPM-listed precious-metal refiners (Au / Ag / Pt / Pd) at facility coordinates. Each popup links to the refiner's website + the LBMA/LPPM Good Delivery list. Source: lbma.org.uk/good-delivery + lppm.com/good-delivery.
Vaults
Named precious-metal vault operators — the 8 LBMA London bullion custodians (Bank of England, Brink's, G4S, HSBC, ICBC Standard, JPM, Loomis, Malca-Amit), 6 COMEX-approved NY metro vaults, plus key Asia bullion hubs (HK, Singapore, Le Freeport) and Swiss freeports. Source: LBMA membership list + CME Group COMEX-approved precious-metal warehouses.
Mints
13 sovereign / state-owned coin-producing mints (US, Royal Canadian, Royal Mint, Perth, Monnaie de Paris, Münze Österreich, Japan Mint, China Gold Coin, South African Mint, etc.) at their flagship production facility. Source: each mint's own official site — see /ecosystem/mints/ for the full directory.
Free Zones & Freeports
Metals-relevant free trade zones, freeports and bonded airport areas — Swiss-style freeports (Geneva, Zurich, Chiasso, Luxembourg, Singapore), Middle East commodity FTZs (DMCC, JAFZA, DAFZA), Chinese pilot FTZs (Shanghai Waigaoqiao, Shenzhen, Tianjin, Hainan), HK Airport bonded, Incheon FEZ, UK post-2021 freeports (Teesside, East, Liverpool), Trieste Free Port. Each popup links to the zone authority. Source: each zone's official authority site.
Sanctions hotspots
Country-level density of metals-relevant sanctions designations from the five primary lists (OFAC SDN, OFAC Consolidated, EU FSF, UK OFSI, UN Security Council). Bubble radius is proportional to √(designation count). Click a bubble for a breakdown by subject type (companies / individuals / vessels) and by issuing authority. Source: /ecosystem/sanctions/ · raw JSON: /data/sanctions/latest.json.
Carbon intensity (producer disclosures)
Verified facility-level Scope 1+2 carbon intensity from primary producer disclosures — BlueScope Port Kembla (steel, 1.44 t/t), Kamoa-Kakula (copper, 0.16 t/t), Nickel Industries HPAL Morowali (nickel, 6.97 t/t), Sibanye-Stillwater Cooke (gold, 9.98 t/oz). Marker colour = ratio vs the metal’s global average (green < 0.5× — best-in-class, yellow < 1×, orange < 2×, red ≥ 2×). See the Carbon Intensity Atlas table below for all sources and methodology.
Universities
60 mining engineering, extractive metallurgy and mineral-economics schools across 8 world regions — exact roster from /education/.
About this map
Built on free, open-source tooling. Map rendering uses Leaflet (BSD-2-Clause) on top of OpenStreetMap tiles (ODbL). No vendor map SDKs or API keys are involved.
Primary sources only. Reserves figures pass through unchanged from USGS Mineral Commodity Summaries 2026 — every reserves popup links directly to the relevant USGS PDF. Warehouse, exchange and university popups link to the operator's own official page. We do not re-encyclopaedify any of this data.
Port operator data. Each port popup shows the legal operator and ultimate parent group with stake and concession year, sourced from each operator's annual report (COSCO Shipping Ports HKEx 1199, China Merchants Port Holdings HKEx 144, DP World, Adani Ports NSE, PSA International, APM Terminals via A.P. Møller-Mærsk, Hutchison Ports via CK Hutchison HKEx 0001) and the relevant port authority disclosures. TSM does not classify ownership — only mirrors what issuers publicly disclose.
Coordinates are approximate centroids (~10 km precision) used only to place markers — not republished from any vendor map dataset. Reserves circle size is proportional to the square root of tonnage so small producers stay visible next to giants.
