Charted: China Holds 9 of 14 Mapped Top-1 Seats — Cobalt Flips 66 pp From DRC Mine to China Refine

Our research ledger asked which physical inputs modern industry treats as always-on. The concentration companions then measured how top-heavy those markets are — Top-1, Top-3, HHI — across mine and midstream stages. This post answers a different desk question: where does activity, risk, and capacity sit on the map? Concentration tells you the tip is thick; geography tells you which countries and regions hold the tip, and whether the pit and the plant even live on the same continent.

The interactive dashboard above is built as a geography lens, not another Top-k ladder. Toggle Country / region shares, Mine → mid flips, Mine × mid scatter, and Regional hubs. On shares, flip stage (mine vs midstream) and lens (country bars vs regional pie). The punchline is deliberately two-map. On mine geography, Top-1 seats still scatter across Africa (cobalt, platinum), Oceania (lithium), Latin America (copper), Southeast Asia (nickel), and East Asia (graphite, rare earths, phosphate). On midstream geography, East Asia — almost entirely China — holds all six mapped midstream Top-1 seats, and China alone stacks nine of fourteen total Top-1 seats across mine and plant.

The headline map: pits plural, plants East Asian

Read the table as a family of maps, not one slogan. Mine geography answers which regions dig. Midstream geography answers which regions refine, separate, or chemically convert. Flip meters answer whether those two maps agree. Averaging them into “China owns critical minerals” is a category error for cobalt and copper — Africa and Latin America still own large pieces of the pit — and understates the plant story for gallium, graphite anodes, and rare-earth separation, where East Asia’s share is already near-monopoly.

Country shares: start with cobalt’s two continents

Filter Country / region shares → Mine → Cobalt (mine). Congo (Kinshasa) prints about 74% of mined cobalt, with Indonesia, Russia, and Australia as thin runners-up. Switch the commodity to Cobalt (refined) under Midstream and the map inverts: China holds about 76% of refined cobalt, with Finland and Canada as small OECD footnotes. That is the largest geographic flip in the panel — a 66 percentage-point Top-1 seat change across a single stage boundary — and the reason battery desks cannot treat “cobalt risk” as one country.

Repeat the exercise for copper. Chile leads mine output near 24%, with Peru and the DRC each near 10% and China itself only about 8% of the pit. Open Copper (refined) and China jumps to about 44% of refined metal. The copper mine-vs-refinery geography post unpacks that gap in tonnage; here it sits as one row in a multi-commodity map that says the same thing in lithium (Australia pit / China chemicals) and, more softly, in rare earths and graphite (China already leads the pit, then thickens further at separation and anode processing).

Toggle the lens to Regional pie when you want continents rather than country bars. Cobalt mine is an Africa-dominated pie; cobalt refine is an East Asia–dominated pie. Lithium mine is an Oceania + Latin America story; lithium chemicals collapse toward East Asia. The regional pie does not invent new facts — it makes the stage flip impossible to miss at thumbnail scale.

Mine → mid flips: five metals, one direction

Open Mine → mid flips. The dumbbell panel plots mine Top-1 share (amber) against midstream Top-1 share (rose) for cobalt, copper, lithium, rare earths, and graphite. Cobalt’s Δ is 66 pp. Copper’s is about 36 pp. Lithium’s is about 28 pp. Rare earths and graphite stay China-led on both sides but still thicken at midstream (+21 pp and +11 pp respectively) — separation and anode processing are even more geographically extreme than the pit.

The geometric reading: every paired metal either keeps China as Top-1 or moves Top-1 toward China when you cross from mine to midstream. No metal in this set flips away from East Asia at the plant. That is the geography companion to the concentration scoreboard, where midstream Top-1 shares already sit higher than mine Top-1 shares for the same battery and magnet chain. Concentration says the tip is thicker downstream; geography says the tip relocates downstream.

Mine × mid scatter: above the diagonal

Switch to Mine × mid scatter. Each point is a paired metal with mine Top-1 share on the x-axis and midstream Top-1 share on the y-axis. Points above the diagonal are midstream-heavier at Top-1. Outlined points keep the same Top-1 country across stages (China mine + China midstream for rare earths and graphite). Cobalt and copper sit far above the diagonal and change Top-1 country — the purest geographic flips. Lithium sits above the diagonal with an Australia→China seat change. The scatter is the dumbbell’s continuous twin: same five metals, same USGS/IEA vintage, different visual grammar for desks that think in quadrants.

Regional hubs: who holds the seats

Open Regional hubs. On Regional Top-1 seats, East Asia dominates midstream (six of six mapped midstream Top-1 seats in this cut land in East Asia) while mine seats still spread across Africa (two), East Asia (three), and one each for Southeast Asia, Latin America, and Oceania. Toggle Country hub stack to see China alone holding nine total Top-1 seats (three mine + six midstream) against single-seat mine specialists: DRC, South Africa, Indonesia, Chile, Australia.

That hub stack is why “diversify mining” and “diversify processing” are not interchangeable policy slogans. Adding a lithium pit in Argentina or a nickel mine in the Philippines can move mine geography without touching the midstream tip. Adding separation capacity in Malaysia or anode capacity in North America is a different capital and permitting problem — and the one that actually relocates Top-1 seats on the plant map. Pair this panel with the Q3 concentration update when the question is whether the tip thickened, and with this geography post when the question is where the tip lives.

Who is exposed — and what would rewrite the map

Exposed on the pit clock: battery and stainless buyers who treat DRC cobalt, Indonesian nickel, Chilean copper, or Australian lithium as “one more mining jurisdiction” without pricing logistics, artisanal-mine governance, export bans, or royalty shocks; fertilizer desks that still underweight Morocco’s rock leverage beside China’s larger absolute phosphate output.

Exposed on the plant clock: OEMs and governments that fund upstream mines while leaving gallium refining, graphite anode processing, rare-earth separation, cobalt refining, and lithium chemicals inside a single East Asian jurisdiction; semiconductor and magnet supply chains for which midstream Top-1 shares already clear 90%+.

Relative winners under current maps: Chinese midstream platforms that convert plural pit feedstock into concentrated chemicals and metals; African and Latin American mine hosts that collect royalties without capturing refine margins; Indonesia’s nickel franchise as a Southeast Asian mine tip that still feeds China-led conversion chains.

What would rewrite the story: multi-year refine and separation capacity outside East Asia that cuts China’s midstream Top-1 count below roughly half of the mapped set; DRC or Indonesian domestic refining that collapses cobalt’s 66 pp flip; copper smelting outside China that pulls refine Top-1 below ~35%; or a lithium chemicals buildout in Australia/Chile/Argentina that keeps chemicals Top-1 closer to the pit map. None of those appear as completed geography shifts in the USGS MCS 2025 / IEA 2025 vintages summarised here.

Caveats and methodology

1. Country shares are USGS Mineral Commodity Summaries 2025 (2024e) restatements for mine and many refine rows; figures are USGS estimates and may not sum to 100% because of rounding.
2. Graphite anode, rare-earth separation, and lithium chemicals midstream shares lean on IEA Global Critical Minerals Outlook 2025 and are labeled secondary where USGS does not publish a matching country table.
3. Regional aggregates re-bucket USGS country rows into East Asia, Southeast Asia, Africa, Latin America, North America, Europe, Middle East, Oceania, and Otheranalytical geography, not a USGS publication field.
4. Top-1 seat counts are counted across the eight mine + six midstream ledgers in this geography map, not across every commodity in the research ledger.
5. Flip Δ (pp) is the absolute gap between mine Top-1 share and midstream Top-1 share for paired metalsa stage-boundary meter, not a trade-flow volume.
6. Helium, palladium, antimony, tungsten, and germanium appear in concentration/research posts but are not every one re-mapped here; this post prioritises metals with a clear mine↔midstream geographic story.
7. Do not average mine shares and midstream shares into one “China % of critical minerals.” Different stages, different denominators.
8. This post is a geography companion. For Top-k / HHI use the concentration print; for levels and sector tags use the research ledger; for copper tonnage detail use the mine-vs-refinery geography cut.

Bottom line

Mine geography for chokepoint commodities is still plural — Africa, Oceania, Latin America, and Southeast Asia all hold mine Top-1 seats. Midstream geography is not. East Asia holds all six mapped midstream Top-1 seats, China alone stacks nine of fourteen total Top-1 seats (three mine + six midstream), and cobalt’s DRC→China flip is a 66 pp seat change across one stage boundary. The economy can keep assuming physical inputs will clear; the map says the plant that clears them is far more geographically concentrated than the pit that digs them.
