Teck Resources:
Canada’s copper transition trade.

Teck Resources (TSX: TECK.B) is Canada's largest diversified miner, historically driven by copper, zinc, and metallurgical coal. The 2023 sale of its steelmaking coal division to Glencore transformed Teck into a pure-play base metals company — making it Canada's most direct equity exposure to the copper energy-transition thesis.

The QB2 copper transformation

Teck's Quebrada Blanca Phase 2 (QB2) project in Chile ramped up in 2023–2024, roughly doubling Teck's copper production capacity. QB2 is a large-scale, long-life asset — 28 years of mine life — that positions Teck as a significant global copper producer for decades. The capital-intensive ramp-up phase is complete; the company now enters a harvest phase of high free cash flow generation at current copper prices.

At LME copper $12,043/t, QB2's economics are exceptional. The all-in sustaining cost for QB2 is estimated at $1.80–$2.00/lb ($3,970–$4,400/t) — giving Teck a margin of over $3,000/t at current prices. This is the sell signal, not the buy signal.

Zinc exposure: industrial economy barometer

Zinc — used primarily for galvanising steel against corrosion — tracks the global manufacturing and construction cycle more closely than copper. Teck's Red Dog mine in Alaska is the world's largest zinc mine, providing earnings diversification. When copper and zinc cycle together (as in 2021–2022), Teck's earnings are spectacular. When they diverge, Red Dog provides a buffer against copper weakness.

Current signal: copper at SELL, zinc neutral

LME copper at $12,043/t is deep in the Signycle SELL zone. LME zinc at $2,580/t is at the upper end of the neutral band. For Teck, the dominant signal is copper — and it says SELL. The next BUY opportunity for TECK will come when copper approaches $6,500/t and QB2's premium project quality is available at distressed valuations.
