Teck's copper growth and Anglo merger advance, but tariff doubt jolts the sector

Anglo American clears coal sale ahead of Teck merger Anglo American agreed to sell its Australian steelmaking coal assets for up to $3.88 billion, simplifying its portfolio and cutting debt before combining with Teck. The merged company would be over 70% copper, tying Teck more directly to electrification and AI power demand.
This deal removes a hurdle to the merger and sharpens Teck's copper focus, supporting the stock.
Teck mails merger election forms to shareholders Teck sent letters of transmittal to registered shareholders for its court-approved merger with Anglo American. Each Teck share converts to 1.3301 Anglo American shares. The election window is open, and shareholders must act before the deadline to receive consideration.
This is a concrete step toward completing the merger, reducing uncertainty and supporting Teck's price.
Canada backs Teck's Trail critical minerals expansion Canada launched its Critical Minerals Accelerator with Teck's Trail Operations as the first deal. The Canada Growth Fund will invest up to $400 million, with total potential investment up to $850 million to double germanium and antimony output and possibly add gallium. This boosts Teck's growth prospects.
Government funding and streamlined regulation for a new critical minerals project add value and reduce risk for Teck.
Record copper prices drive Q2 earnings surge Teck reported $2.2 billion adjusted EBITDA for Q2 2026, up 204% from last year, as record copper prices and 25% higher production lifted results. Adjusted profit was $1.93 per share. The Anglo American merger remains on track for closing within the original timeline.
Strong earnings show Teck's core business is thriving and the merger is progressing, both positive for the stock.
Anglo Teck leadership named, synergies targeted Teck and Anglo American announced the future executive team for Anglo Teck, with Duncan Wanblad as CEO and Jonathan Price as deputy. The combined company, headquartered in Vancouver, targets about $800 million in annual pre-tax synergies by year four, plus revenue gains from optimizing Chilean copper mines.
Naming leadership and quantifying synergies makes the merger's benefits more concrete, supporting Teck's valuation.
Copper tariff doubt triggers sharp sector selloff Copper mining stocks fell sharply after reports cast doubt on White House tariffs for refined copper. Teck slid 7% to $65.08, and benchmark copper dropped 3.1% from a record high. Despite the drop, Teck remains up 36% year to date.
This is a fresh negative shock that directly hit Teck's price and highlights a key risk for copper producers.

Rio Tinto Q3: Profit Surges, But China Demand and Output Risks Loom

Profit and Dividend Jump First-half profit rose 43% to $6.85bn, helped by an 84% jump in copper earnings from Mongolia. The dividend increased to $2.11 per share, rewarding shareholders.
This is the main positive financial result that drove investor sentiment during the period.
Lithium and Iron Ore Growth Lithium is now the fastest-growing division, targeting 200,000 tonnes by 2028. Q2 iron ore sales rose 5% with better pricing, supporting revenue.
These operational highlights show progress in key growth areas and near-term sales strength.
China Delays Pilbara Blend Purchases China, nearly 60% of revenue, told mills to delay Pilbara Blend purchases amid contract talks, creating near-term sales uncertainty and weighing on sentiment.
This is a major new risk that could hurt sales and investor confidence.
Copper Output Falls and Cost Pressures Copper output fell 7%, while weaker iron ore and lithium prices plus higher expansion debt could pressure returns, offsetting some positive momentum.
These operational and financial headwinds present a real counterweight to the strong profit growth.

Rio Tinto's profit jumps on copper; China iron ore pressure

First-half profit surges 43% Rio Tinto's underlying profit rose 43% to $6.85bn, the best in four years, driven by an 84% jump in copper earnings from Mongolia. The interim dividend increased to $2.11 per share, rewarding shareholders.
This is the core financial result that directly boosts investor confidence and the stock's value.
Growth projects and asset sales advance Rio advanced a $2–3bn infrastructure asset sale, awarded $110m in Resolution Copper contracts, secured Tomago smelter power through 2038, gained Indigenous consent for Winu copper-gold, agreed to buy Aurukun bauxite, and invested $15m in Mogotes Metals.
These actions show Rio is actively strengthening its portfolio and securing long-term operations, supporting future growth.
China delays Pilbara Blend purchases China's state iron ore buyer told mills to delay Pilbara Blend purchases during contract talks, threatening near-term sales. China provides nearly 60% of Rio's revenue, giving Beijing pricing leverage and creating uncertainty.
This is a major headwind that could hurt Rio's sales and pricing power in its largest market.

China ore squeeze hits Rio, but copper and bauxite growth advance

China delays Pilbara Blend iron ore purchases China's state iron ore buyer told steel mills to hold off buying Rio's Pilbara Blend during contract talks. China takes nearly 60% of Rio's revenue, so this directly threatens near-term iron ore sales and gives Beijing leverage over prices.
This is the single biggest new force on Rio's earnings and the stock.
Winu copper-gold project clears Indigenous hurdle Rio won consent from the Nyangumarta people for its Winu copper-gold mine in Western Australia, targeting production by 2030. It is Rio's most advanced new copper project, supporting long-term growth as copper demand rises.
A concrete step forward for Rio's copper expansion, a key growth driver.
Rio buys Aurukun bauxite project Rio agreed to acquire the Aurukun bauxite project in Queensland from Glencore and Mitsubishi, extending its nearby bauxite operations. The deal still needs government approvals, but it strengthens long-term reserves for its aluminium business.
Adds a new growth asset to Rio's bauxite/aluminium pipeline.
Small Mogotes investment expands copper exploration Rio closed a US$15 million investment in Mogotes Metals for about a 5% stake and a technical alliance on the Filo Sur copper project in Argentina and Chile. It is a small but strategic bet on future copper supply.
Shows Rio actively building early-stage copper options, though the financial impact is small.

Rio Tinto's profit jumps 43% on copper; asset sales and smelter deal advance

First-half profit surges 43% on copper strength Rio Tinto's first-half underlying profit rose 43% to $6.85 billion, the highest in four years, as copper earnings jumped 84% on Mongolian output. The interim dividend rose to $2.11 per share. Stronger profit and cash flow support the shares.
This is the period's biggest earnings event and directly lifts the investment case for RIO.LSE.
$2–3 billion infrastructure asset sale draws private equity interest Rio Tinto is selling infrastructure assets in Canada and Western Australia for $2–3 billion, with Blackstone, KKR, Apollo and Stonepeak interested. Proceeds would fund growth and streamline the business, a plus for the shares.
The sale is a concrete step in Rio Tinto's portfolio management plan and could unlock capital for investors.
Resolution Copper advances with $110 million contracts Resolution Copper awarded $110 million in contracts for early work on its Arizona underground mine, part of a $500 million program. Rio Tinto owns 55%. Progress on this large future copper project supports long-term growth expectations.
It shows real progress on a major copper growth project, which matters for Rio Tinto's long-term earnings.
Tomago aluminium smelter secures power through 2038 Rio Tinto-backed Tomago smelter secured a power deal through 2038, with renewables from 2033. This keeps Australia's largest aluminium smelter running and cuts emissions, reducing uncertainty over a key asset.
It removes a major risk to Rio Tinto's aluminium operations and supports stable future production.

Rio Tinto's copper and lithium growth push meets iron ore recovery

Lithium to become fastest-growing division Rio Tinto expects lithium to grow faster than any other division, tripling output to 200,000 tonnes by 2028 using new extraction technology. Rising demand from battery storage, not just electric cars, supports this. A new growth engine lifts the company's long-term earnings outlook.
This is a new strategic growth driver that directly boosts future revenue and investor confidence.
Q2 iron ore sales rise 5% with better pricing Rio Tinto sold 5% more iron ore in the second quarter, with average prices improving to $85.2 per tonne. This shows strong demand for its core product, supporting cash flow. Copper output fell 7%, but lower copper costs and a 20% jump in lithium production partly offset that.
This is the latest operational update showing core business strength and pricing power.
Oyu Tolgoi loan rate adjusted with Mongolia Rio Tinto and Mongolia agreed to lower the interest rate on the Oyu Tolgoi shareholder loan, reflecting reduced project risk. This improves financial terms and eases a long-running dispute. The mine remains on track to produce 500,000 tonnes of copper yearly from 2028.
This resolves a key geopolitical risk and improves project economics, directly benefiting the stock.
Valuation test amid battery metals push A valuation analysis suggests Rio Tinto is 13% undervalued, but weaker iron ore and lithium prices plus higher debt from expansion could pressure returns. The stock fell 9.7% in a month but is up 12.8% this year. The market is weighing growth against near-term headwinds.
This captures the central tension investors face: growth potential versus pricing and leverage risks.
