The effect depends on the price the company actually receives for payable metal, the amount it sells, its contracts and hedges, and any costs or taxes that move with prices or production.
Start with the price a company realizes, not the spot quote
A benchmark or spot price is a market reference. A miner’s realized price is the amount it records for metal sold under its contracts, after applicable deductions and pricing adjustments. The two can differ because of smelter or refining deductions, provisional pricing, streaming agreements, and hedges.

A useful way to think about the first-order revenue effect is: a change in realized price multiplied by payable sales volume. That is an explanatory framework, not a company sensitivity or a formula for forecasting profit. Earnings also reflect costs, taxes, royalties, foreign exchange, production, and the timing of sales.

Some sales are provisionally priced, with a later pricing period determining the final amount. Hudbay Minerals’ 2025 results and management discussion describe provisional pricing, pricing-period hedges, strategic hedging, and streaming arrangements—examples of why a benchmark move may reach reported results at a different time or in a different amount.

Why the three metals affect different miners differently
| Metal | What to examine | Company evidence |
|---|---|---|
| Silver | Silver’s share of revenue, realized selling price, payable ounces, and any gold or base-metal credits. | Silvercorp Metals reported that silver made up 72% of its FY2026 revenue; its realized silver price was reported after smelter deductions. |
| Zinc | Whether zinc is a primary product or a by-product, the quantity sold, treatment charges, and any hedges. | Silvercorp reported meaningful zinc sales alongside silver. Hecla’s 2024 annual report describes zinc, gold, and lead as by-products at Greens Creek, where their value offsets silver production costs. |
| Aluminium | Whether the company mines bauxite, refines alumina, smelts aluminium, or operates across stages—and how price-linked inputs affect those operations. | South32’s FY2026 annual-report search result identifies aluminium-smelter input-price effects as part of price-linked costs. It does not establish a complete net aluminium earnings sensitivity. |
The same metal can therefore play very different roles: it may be a company’s main source of sales, one of several products, or a by-product credit that reduces reported unit costs. A by-product credit can lower a cost measure without making the secondary metal the main driver of the company’s total earnings.
Silver: a strong realized-price move can matter, but mix and sales still count
Silvercorp Metals’ FY2026 results show how realized prices and product mix can shape a reported revenue comparison. The company reported revenue of $438.1 million, up 47% year over year, and said the increase was mainly attributable to a $143.0 million increase from higher realized silver and gold selling prices, partly offset by lower metal sold. Silver represented 72% of FY2026 revenue.
Silvercorp reported a FY2026 realized silver selling price of $46.44 per ounce after smelter deductions, 72% above FY2025. That is the company’s realized price for the stated reporting period, not a universal price received by silver miners. The revenue explanation also includes gold prices and lower metal sold, so it should not be read as a standalone silver-price-to-earnings sensitivity.
Zinc: price exposure can come from sales, hedges, or cost credits
For a zinc producer, a higher realized zinc price can increase sales revenue on payable tonnes, subject to the company’s sales terms and hedges. Treatment charges also matter where ore or concentrate is processed: Nexa Resources identifies treatment charges as material to mining and smelting results. The available FY2025 annual-report search result does not support a detailed numerical estimate of their effect, so it should not be used to infer a zinc earnings sensitivity.
Rank #3
Zinc can also affect a mine whose headline product is silver. Silvercorp’s FY2026 disclosures show that it sold zinc alongside silver, meaning zinc’s realized price and sales quantity contribute to its product revenue. At Hecla’s Greens Creek operation, the 2024 annual report describes zinc, gold, and lead as by-products whose value offsets silver production costs. In that setting, a zinc-price change can affect a reported unit-cost measure through the credit, even though the mine is also producing silver.
Check how a company defines any cash-cost or all-in sustaining cost (AISC) measure before interpreting a by-product credit. Such non-GAAP cost measures are not interchangeable with operating earnings under accounting standards, and a lower reported unit cost does not by itself establish that total profit rose by the same amount.
Aluminium: assess the whole operating chain and its input costs
Aluminium exposure depends on where a company operates in the chain: bauxite mining, alumina refining, aluminium smelting, or several of these stages. A higher aluminium selling price may help the sales side, while price-linked inputs can offset part of the benefit at a smelter. South32’s FY2026 report search result flags aluminium-smelter input-price effects in its price-linked cost discussion, but does not establish a complete verified numerical net sensitivity. It would therefore be misleading to quote a universal earnings gain for a given aluminium-price move.
For an integrated producer, segment mix matters too: a change that benefits one stage may have a different effect on another. Look for the company’s own price-variance explanation and its treatment of input costs rather than applying the aluminium benchmark to the group’s total earnings.

Hedges and contracts can change the timing and size of the effect
A company that has hedged sales may receive an effective price different from the current market benchmark for the covered volume. Hedging may reduce upside when prices rise as well as limit downside when prices fall; the exact outcome depends on the instruments, volumes, and periods involved. Provisional pricing and pricing-period hedges can also shift when a price change appears in results. Streaming agreements may alter the economics of specific metal sales.
Hindustan Zinc said its strategic hedging is intended to support predictability of revenue, EBITDA, and cash flows. In its FY2025-26 Integrated Annual Report, the company disclosed hedging 71 kt of zinc and 59 tonnes of silver at average prices of US$3,133 per tonne and US$60 per troy ounce, respectively. These are the company’s reported FY2026 hedge positions and average prices—not spot prices, forecasts, or sensitivities for other producers.
How to assess a company’s exposure in its filings
- Identify the metal’s role. Check revenue and production disclosures to see whether zinc, silver, or aluminium is a primary product, a by-product, or one segment of a diversified business.
- Find realized prices and payable sales. Compare the reported realized price and payable quantity for the same period. Note deductions, provisional-pricing adjustments, and the company’s definition of realized price.
- Read the sales and risk-management terms. Look for hedged volumes, pricing periods, streaming arrangements, and where related gains or losses enter reported results.
- Check offsets before drawing a profit conclusion. Review treatment and refining charges, by-product credits, price-linked inputs, operating costs, royalties, and taxes.
- Separate price effects from operating changes. Grade, recovery, production, mine sequencing, and the amount sold can change alongside prices, making a simple year-over-year comparison an unreliable measure of price sensitivity.
No single cross-industry numeric sensitivity is established for zinc, silver, or aluminium. A company’s own sensitivity table, when available, applies to its stated assumptions, reporting period, and exposure; it should not be transferred to another miner.
