BHP's Copper Assets Are Worth More Than the Market Thinks
The Western minerals alliance is a decade-long tailwind for BHP's copper portfolio. At 14.6x forward earnings, the stock underprices the coming supply deficit.
BHP at 19.1x, Rio Tinto at 16.2x, and Newmont at 18.9x earnings — the mining sector is offering value the market hasn't noticed.
The mining sector is quietly offering some of the best value in global equities right now. While the market obsesses over AI multiples and tech earnings, BHP, Rio Tinto, and Newmont are trading at single-teen P/E ratios with dividend yields that make bond investors jealous.
Copper demand from electrification and data centres, iron ore's structural floor from Asian infrastructure, and gold's resurgence as a geopolitical hedge — three different commodities, three different demand drivers, all converging on one theme: the market is underpricing hard assets.
BHP trades at 19.1x earnings with a market capitalisation of $195 billion and a dividend yield north of 5%. The analyst consensus target of $65.71 implies roughly 12% upside before dividends. Revenue has pulled back from the iron ore boom peaks but stabilised around $53-56 billion.
The copper story is what makes BHP interesting at these levels. Management has been repositioning the portfolio toward copper for three years — the attempted Anglo American acquisition was the most visible signal. Copper exposure now represents over 25% of group EBITDA, up from 15% five years ago. With copper prices structurally supported by EV demand and grid infrastructure, BHP's pivot is paying off ahead of consensus expectations.
Across three complete cycles, the pattern is always the same: management underestimates costs by 20-30% and the market underestimates duration by 2-3 years. BHP's capex discipline this cycle has been notably better than history.

Rio Tinto at 16.2x earnings is the cheapest of the big three diversified miners. Market cap of $160 billion with a consensus target of $96.83 — implying 18% upside. That's a striking gap for a company of this quality.
Rio's iron ore franchise remains the crown jewel. The Pilbara operations are the lowest-cost iron ore production system on the planet, generating cash margins above 60% even at current prices. The Simandou project in Guinea adds a growth dimension the market has discounted due to execution risk — but first ore is now firmly in the 2026-2027 timeline.
The aluminium business, often overlooked, is benefiting from the same electrification tailwinds as copper. Aluminium demand for EV lightweighting and grid infrastructure is growing at 4-5% annually versus the historical 2% baseline.
Newmont at 18.9x earnings with a $132 billion market cap is the world's largest gold miner at a moment when gold is trading near all-time highs. The consensus target of $140 implies 7% upside — but that target was set when gold was $200/oz lower.
Gold has rallied on central bank buying, geopolitical uncertainty, and de-dollarisation fears. Newmont's all-in sustaining costs sit around $1,200-1,300/oz, meaning every dollar above that drops straight to margin. At $2,300+ gold, Newmont's margin expansion is extraordinary — and the Street's models haven't fully caught up.
The Newcrest acquisition, completed in late 2023, added Tier 1 assets in Australia and Canada. Integration costs have compressed near-term earnings, which is why the trailing multiple looks merely average. The forward picture — with integration synergies kicking in and gold prices elevated — looks considerably better.
All three miners are attractively valued, but Rio Tinto at 16.2x earnings with 18% upside to consensus is the standout. The Pilbara iron ore franchise generates cash in any price environment, the aluminium business is an underappreciated electrification play, and Simandou adds growth optionality. BHP's copper pivot makes it the best structural story, and Newmont offers leveraged exposure to gold's rally. For a portfolio approach, equal-weight all three — the combined dividend yield exceeds 4% and the sector is pricing in a commodity downturn that the demand data doesn't support.

The Western minerals alliance is a decade-long tailwind for BHP's copper portfolio. At 14.6x forward earnings, the stock underprices the coming supply deficit.
BHP directors bought shares after the failed Anglo American bid. Rio insiders have been quiet for nine months. The divergence in insider conviction, combined with BHP's copper pivot, makes the choice clear.
At 10x earnings with an 8% dividend yield, BHP is priced for permanent iron ore decline. The copper pivot — with demand set to rise 50-70% by 2040 — could drive a 30-50% re-rating.
