The Lode

Welcome to the first edition of The Lode, Bloodstone Research’s weekly intelligence note on global metals and mining.

Every Friday, we’ll look beyond the benchmark price: into inventories, physical flows, mine supply, projects, capital and the emerging economies that control much of the world’s mineral wealth.

We launch during an extraordinary August for metals. Copper has just experienced one of the sharpest LME squeezes in years. Aluminium exchange inventories are at levels last seen in 1990. Platinum is heading towards a fourth consecutive annual deficit. Three metals. Three different forms of scarcity.

Copper: Squeeze Meets Surplus

Copper hit a record $14,912/t during one of the most extreme LME squeezes in years — despite forecasts pointing towards a refined-market surplus in 2026. More than 38,000 tonnes have since returned to LME warehouses and the squeeze is beginning to unwind. Has the pressure broken, or merely eased?

Aluminium’s Hidden Liquidity Gap

LME aluminium stocks have fallen to levels last seen in 1990. Yet China, Indonesia and recovering Gulf production are simultaneously improving the global supply picture. That creates an unusual possibility: global aluminium supply normalises while exchange liquidity remains tight.

Platinum: The Buffer Is Disappearing

Platinum is heading towards a fourth consecutive annual deficit. But this year’s projected shortfall is substantially smaller than last year’s. The more interesting question is what three previous deficits have already done to the market’s ability to absorb the next supply shock.

Scarcity Isn’t the Same as Shortage

Copper has just experienced an extraordinary LME squeeze, yet the International Copper Study Group forecasts a modest refined-market surplus for 2026.

Aluminium exchange inventories are at 36-year lows, yet global supply is beginning to recover.

Platinum is heading for a fourth consecutive annual deficit, yet this year’s shortfall is expected to be considerably smaller than last year’s.

The apparent contradictions tell us something important. The issue increasingly isn’t simply how much metal exists. It is where it sits, whether it can reach the market and how much buffer exists when something goes wrong.

Copper demonstrated the first problem spectacularly this month. An unusually small pool of immediately deliverable LME metal collided with large positions, sending cash copper to a record and producing extreme backwardation. Metal has since returned to warehouses and the squeeze has begun to unwind.

Aluminium presents the second. Global availability can improve through Chinese product exports, Indonesian capacity and Gulf restarts without immediately solving the shortage of readily available LME metal.

Platinum presents the third. Another annual deficit matters, but perhaps more important is what successive deficits have already done to the inventory available to absorb the next disruption.

Copper has shown how location can create scarcity. Aluminium is showing how liquidity can diverge from supply. Platinum is showing what happens when the physical buffer disappears.

That is where we begin.

The Metal Price Is Only Half the Trade

Copper’s August squeeze creates an obvious temptation: find the miners with the greatest copper exposure and assume they provide leveraged exposure to higher prices.

We think that is too simplistic.

A benchmark price created partly by exchange scarcity is not the same thing as a permanent improvement in the economics of producing the underlying metal. If deliverable copper returns to warehouses and spreads normalise, part of the scarcity premium can disappear considerably faster than a mining company can change its production profile.

For miners, what matters is the ability to convert elevated prices into cash. Existing production matters. Ore grades matter. Power availability matters. Processing capacity matters. Jurisdiction matters. Capital intensity matters. A copper project requiring billions of dollars and a decade of development does not suddenly become equivalent to an operating mine because copper briefly trades above $14,000/t.

The same applies elsewhere. South Africa’s dominance of platinum supply creates scarcity value but also concentrates operational risk. Indonesia’s aluminium build-out creates new supply, but announced capacity only matters when it becomes reliable production capable of reaching customers.

That suggests the more interesting mining question may not simply be: which metal is scarce? But: who already owns the tonnes the market needs?

As high commodity prices encourage another round of ambitious mine-development plans, that distinction becomes increasingly important.

The best-positioned miners may not be those promising the most tonnes ten years from now. They may be those capable of producing the right metal today.

01 — Copper Inventories

The LME warehouse rebuild has started. Whether it continues will tell us far more about the durability of August’s squeeze than the outright copper price.

02 — Aluminium Liquidity

Global supply is improving. Exchange liquidity remains exceptionally tight. Watch whether the gap closes — and from which direction.

03 — Platinum’s Buffer

Another deficit is coming. South African production and recycling will determine how much further the remaining inventory cushion is depleted.

04 — China

Grid investment, manufacturing, property and infrastructure remain the underlying test of industrial-metals demand.

05 — US Trade Policy

Tariffs are increasingly determining where copper and aluminium physically move, creating regional premiums and inventory distortions that can overwhelm conventional supply-demand signals.

The Bottom Line

Metals markets are rarely as simple as surplus or deficit.

Copper’s August squeeze was about location. Aluminium’s scarcity is increasingly about liquidity. Platinum’s vulnerability comes from the erosion of its physical buffer.

For investors, understanding where the scarcity sits may now matter as much as determining whether scarcity exists at all. That’s where The Lode starts.
