The effect depends on the price the company actually realizes on payable sales, how much it sells, its hedges and contracts, and any offsetting changes in costs, taxes, or production. A metal’s importance also depends on whether it is the company’s main product, a by-product, or part of an integrated smelting business.
How a metal-price change reaches earnings
A spot or benchmark price is a market reference, not necessarily the price a miner receives. Companies sell under contracts with their own pricing periods and deductions; the amount sold and the portion considered payable also matter. A useful way to think about the first-order revenue effect is:
Approximate revenue effect = change in realized price × payable sales volume.
This is an explanatory framework, not a quoted company sensitivity or a formal valuation formula. The earnings effect is further shaped by hedges, contract terms, treatment and refining charges, price-linked costs, taxes, royalties, and operational changes. A higher benchmark can therefore raise revenue while producing a smaller, delayed, or otherwise different change in profit.

Why spot prices differ from realized prices
A miner’s realized price is the amount it records for metal sold under its contracts and accounting policies. It can differ from a benchmark because of the contract’s pricing period, smelter deductions, treatment or refining charges, streaming arrangements, and adjustments when provisional prices are finalized. Payable volume is also distinct from the amount of metal produced: contract terms determine what quantity is paid for, and sales timing determines which prices apply.
Hudbay Minerals’ 2025 results and management discussion describe provisional pricing, pricing-period hedges, strategic hedging, and streaming arrangements. These are company-specific terms, but they illustrate why a spot-price chart alone cannot establish what a miner received in a reporting period. Silvercorp Metals, for example, reported its FY2026 realized silver selling price after smelter deductions rather than treating the benchmark quote as its realized price.
How exposure differs across zinc, silver, and aluminium
| Metal | How it may affect a company | Company-specific illustration |
|---|---|---|
| Zinc | It may be a principal product or a co-product, and its earnings contribution depends on realized price and payable sales. Hedging and smelting terms can alter the exposure. | Silvercorp reported zinc sales alongside silver in FY2026. Hindustan Zinc disclosed zinc hedges for FY2025-26. Nexa’s FY2025 annual-report materials identify treatment charges as relevant to mining and smelting results. |
| Silver | Its effect depends on its share of revenue and profit, realized price after deductions, sales volume, and any price protection or streaming arrangements. | Silvercorp’s FY2026 results show silver as a major revenue driver; Hecla’s 2024 annual report describes silver production at Greens Creek alongside valuable by-products. |
| Aluminium | For a producer with smelting operations, a higher aluminium selling price may coincide with price-linked input costs. The net effect depends on both sides of the business. | South32’s FY2026 annual-report materials identify aluminium smelter input-price effects as part of price-linked costs. The cited material does not establish a complete numerical net sensitivity. |
These examples are not interchangeable sensitivities. They show why a reader should establish the named company’s business mix and contract structure before inferring an earnings effect from any one metal price.
Product mix determines which metal matters most
For a multi-metal miner, a price move in a secondary metal can matter less than a smaller move in its dominant revenue source—or more than its label as a “by-product” suggests. The relevant questions are how much of each metal is sold, what price is realized, and how much of the company’s costs are allocated or offset by that metal.
Rank #3
Silvercorp Metals reported FY2026 revenue of $438.1 million, up 47% year over year, and said silver represented 72% of revenue. Its FY2026 realized silver selling price was $46.44 per ounce after smelter deductions, 72% higher than in FY2025. The company attributed most of the annual revenue increase to higher realized silver and gold selling prices, while lower metal sold partly offset that increase. Those figures describe Silvercorp’s own fiscal-year comparison; they are not a general silver-miner earnings sensitivity.
Silvercorp’s example also cautions against assuming that a silver-focused producer has no meaningful zinc exposure: the company reported zinc sales alongside silver. The contribution of zinc still depends on the quantity sold and its realized price, not merely on the presence of zinc in the product mix.
Hedges, provisional pricing, and streams change timing and exposure
Hedges
A hedge can limit exposure to some price movements or shift when they affect reported results; the outcome depends on the quantity, price, duration, and accounting treatment of the positions. Hindustan Zinc said its strategic hedging is intended to support predictability of revenue, EBITDA, and cash flows. In its FY2025-26 disclosures, it reported hedging 71 kt of zinc at an average US$3,133 per tonne and 59 tonnes of silver at an average US$60 per troy ounce. These are the company’s disclosed hedge positions and average prices, not spot prices or forecasts.
Hindustan Zinc’s CFO described the environment as one of volatility in commodity prices, energy inputs, foreign exchange, and regulatory developments, and said the company remained focused on disciplined risk management. The point for readers is to inspect what is hedged and how the company reports it, rather than assume every unit sold moves with the benchmark.

Provisional pricing and streaming
Under provisional pricing, a sale may initially be recorded using a provisional price and later adjusted when the applicable pricing period ends. A price change can therefore affect a different reporting period from the shipment. Streaming arrangements can also alter the portion of production whose economics track prevailing prices. Hudbay’s 2025 reporting discusses both provisional pricing and streaming, so its reported metal exposure must be read with those arrangements in view.

Revenue sensitivity is not profit sensitivity. A producer’s operating costs, royalties, taxes, and other price-linked expenses may move with output, input markets, or regulations. In aluminium smelting, changes in the selling price should be assessed alongside linked input costs; South32’s FY2026 reporting materials identify such input-price effects, but do not establish a complete net aluminium sensitivity in the cited information.
By-product credits create another important link. Hecla’s 2024 annual report describes zinc, gold, and lead as by-products at its Greens Creek operation whose values offset silver production costs. If one of those by-product prices rises, it can improve the reported unit-cost measure for the primary silver operation even if silver itself is unchanged. That accounting presentation is not the same as a direct increase in silver sales revenue, and non-GAAP cash-cost or all-in sustaining cost measures should not be treated as interchangeable with operating earnings.
Production can also confound a price comparison. Changes in ore grade, recovery, mine sequencing, or output may alter both the quantity sold and unit costs in the same period. A year-over-year earnings change cannot be attributed to metal prices alone unless the company’s volume and operating changes are considered too.

How to assess a miner’s price sensitivity
- Identify the relevant business and reporting period. Check whether the company mines the metal, smelts it, or operates across several stages, and note the geography, fiscal year, and segment covered.
- Check revenue and product mix. Find the share of revenue or production associated with the metal, and distinguish primary products from by-products.
- Read realized-price and sales-volume disclosures. Compare realized prices with the relevant benchmark, then check payable quantities sold and any provisional-price adjustments.
- Review contract deductions and arrangements. Look for treatment and refining charges, streams, pricing periods, and other terms that separate benchmark prices from realized proceeds.
- Read hedge disclosures with their units and dates. Determine what volumes are hedged, for what periods, at what disclosed prices, and where hedge gains or losses appear in the accounts.
- Check offsets and operating changes. Review input costs, by-product credits, taxes, royalties, production, grade, recovery, and mine sequencing before attributing an earnings change to price.
- Use only company- and period-specific sensitivities. If management provides a sensitivity, check its assumptions and scope. A sensitivity for one company or reporting period is not a cross-industry rule.
Applied to the disclosures above, this method explains why the FY2026 Silvercorp revenue increase cannot be read as a universal silver-price multiplier, why Hindustan Zinc’s disclosed average hedge prices are not spot quotes, and why an aluminium producer’s selling-price exposure needs to be considered with its input costs.
