The short read
- The U.S. net import reliance for refined copper jumped to 57% in 2025 from 45% in 2024; Chile supplied 68% and Canada 16% of imports over 2021–24.
- The commodity thesis and the company thesis need separate evidence. A strong price cycle encourages new supply; a weak balance sheet forces financing before a project pays.
- Teck and Hudbay are two producing starting points. Teck’s pending merger with Anglo American means its shares are, for now, a special situation as much as a copper bet.
The North American copper problem
Copper is the metal that electrification runs on, and the United States does not produce enough of it.
Those numbers describe a genuine dependency, and Canada sits second on the list of suppliers. It is tempting to stop there and reach for a list of Canadian copper tickers. Resist it. A useful end market is only the beginning of an investment case. The questions that matter to an owner are more specific: what price is already reflected in the shares, what the company can actually produce and sell, and how much cash remains after operating costs, sustaining capital, taxes and the people who get paid before shareholders do.
What the asset map tells us — and what it doesn’t
Two Canadian producers make reasonable starting points because both already operate mines rather than promising to.
These issuer descriptions establish a connection to the theme. They do not establish that either company is undervalued, and they do not tell you what a tonne of copper from each mine costs to produce once by-product credits, treatment charges, royalties and sustaining capital are accounted for. That reconciliation — from “payable production” in a press release to “cash from operations less sustaining capex” in the financial statements — is the actual work, and it is work we have not yet completed for either company. Our profiles say so, in the form of blank fields marked not yet verified.
Production is not free cash flow
For an operating mine, begin with payable production, realized prices and reported unit costs. Then reconcile those measures to the consolidated accounts. Companies define “all-in sustaining cost” differently; by-product credits can make a copper mine with a lot of gold look cheaper to run than it is; and sustaining capital has a way of growing as a mine ages.
For a development project the unanswered questions shift. A resource estimate is not a reserve. A feasibility study is not funding. A construction schedule is not a guarantee. Time to first cash flow, financing terms and cost overruns usually matter more than the size of the deposit, and the long permitting timelines for new North American copper mines are the main reason the import figures above look the way they do.
Teck in 2026 is a special situation
The single most important fact about Teck this year is not a copper fact.
Hudbay is the simpler case: an operating producer with a development project whose main variables are the usual ones — cost performance at Constancia and Copper Mountain, the permitting and financing path for Copper World in Arizona, and how much of the copper story is really a gold story once by-products are counted.
Keep the valuation perimeter consistent
Any comparison between the two should use the same valuation date, currency and copper-price assumption. Enterprise value has to be reconciled to the latest capital structure, and project ownership — Teck owns a share of Quebrada Blanca, not all of it — must be reflected in asset-level economics.
Do not compare a producer’s current cash flow with a developer’s distant forecast as though the numbers carry the same certainty. The market may be charging for genuine financing or operating risk. Any apparent discount needs an explanation before it earns the label “value.”
What would change our view
Two businesses. Separate questions.

The other side of the thesis
What could break it
- A strong long-term demand case can coincide with a weak price cycle; higher prices also bring new supply and substitution.
- Execution shortfalls, cost inflation and rising sustaining capital reduce the cash that reaches shareholders.
- Permitting, water, power and community constraints can delay projects by years, not quarters.
- Financing terms — streams, royalties, convertibles, equity — can transfer value away from existing shareholders.
- Teck-specific: the Anglo American merger could be delayed, conditioned or lapse; the standalone and combined cases differ materially.
- Tariffs and trade policy can change the economics of cross-border copper flows quickly.
