McEwen Mining (MUX) Q4 2025 earnings review
Record Prices and Accounting Shifts Drive Massive Earnings Rebound
McEwen Mining ended 2025 on a high note, posting $64.6M in Q4 revenue (+28% QoQ) and swinging to a $38.1M net profit. While the surface-level numbers look spectacular, investors must look under the hood: the profit surge was heavily aided by a $27.5M deferred tax asset recovery and the transition to capitalizing Los Azules development costs. Operationally, the story is mixed. The San José mine is firing on all cylinders and throwing off cash, but the Fox Complex missed 2025 targets and faces a very weak 2026 production outlook. The long-term bull thesis rests entirely on doubling production by 2030 and monetizing the massive Los Azules copper asset.
🐂 Bull Case
The flagship copper project received RIGI approval in Argentina (granting 30-year tax/FX stability) and published a feasibility study projecting a $2.9B NPV(8%). It is now a highly attractive candidate for a spin-out or joint venture.
The 49%-owned San José mine is thriving under high silver/gold prices. It distributed an $8.8M dividend to MUX in Q4, and management expects $50M+ in dividends in 2026 to help fund organic growth without equity dilution.
🐻 Bear Case
Despite a gold bull market, MUX is struggling to expand margins meaningfully. FY26 AISC guidance is set at a lofty $2,400-$2,600/oz, exposing the company to significant downside risk if metal prices retrace.
The Fox Complex missed its revised 2025 guidance, producing just 23k GEOs against a 25k-28k target. Worse, FY26 guidance projects a further decline to 16k-19k GEOs before the Stock mine comes online, indicating a painful near-term gap.
⚖️ Verdict: ⚪
Neutral. The macro environment is bailing out sub-par operational execution at the 100%-owned mines. The real value is locked in Los Azules, making MUX more of a copper development play than a reliable gold producer right now.
Key Themes
Los Azules Moves from Income Drag to Balance Sheet Asset
Following the release of the Feasibility Study in October 2025, McEwen began capitalizing Los Azules development costs under U.S. GAAP. This simple accounting shift removes a massive weight from the income statement (which dragged down Q1-Q3 earnings) and will dramatically improve reported profitability in 2026. The project's implied market value, based on recent financing, sits at $457M ($7.69 per MUX share).
AISC Remains Dangerously High
While revenue is surging due to record $4,436/oz realized gold prices, operational costs are uncomfortably high. Consolidated 2025 AISC was $2,444/oz. The 2026 guidance offers no relief, targeting $2,400-$2,600/oz. Inflation in Argentina and high stripping/development costs in Nevada and Canada are eating into the commodity price windfall.
Fox Complex Gap Year
The Fox Complex is entering a rough transition period. Production fell from 30,151 GEOs in 2024 to 23,187 in 2025 due to weather and mill shutdowns. 2026 guidance is a dismal 16,000-19,000 GEOs as the company bridges the gap until the new Stock mine reaches commercial production in 2027. This forces the company to rely entirely on Gold Bar and San Jose for cash flow in 2026.
Aggressive Consolidation and M&A
Management is actively consolidating land packages to support its 2030 growth vision. MUX is acquiring Golden Lake Resources (closing April 2026) to expand the Gold Bar footprint, integrating the Tartan Mine (acquired via Canadian Gold Corp), and took a 27.3% strategic stake in Paragon Advanced Labs to leverage new PhotonAssay technology.
Net Income Quality is Low
The headline $38.1M net income for Q4 is highly misleading. It includes a massive $27.5M one-time deferred tax asset recovery. Operating cash flow for the entire year was a modest $7.5M, starkly contrasting the $34.4M full-year net income. Investors must look at cash flow, not GAAP net income, to judge the health of operations.
Other KPIs
Accelerating. Up drastically from $11.8M in Q3 and $17.3M in Q2. This removes the noise of McEwen Copper's historical expensed losses and taxes, providing a cleaner view of the cash generated by the gold/silver mining operations. The jump is primarily driven by 28% higher realized gold prices ($4,436/oz) and strong San Jose volumes.
Reversing. A massive improvement from negative $6.5 million at the end of 2024. Total cash and equivalents ballooned to $51.0M, aided by $110M in convertible notes issued earlier in the year. This ensures the company has sufficient runway to fund the Stock mine ramp and Gold Bar expansion.
Guidance
Stable. The midpoint of 120,000 GEOs represents slight growth over 2025 actuals (115,687), but remains well below 2024 levels (135,884). San Jose and Gold Bar are expected to carry the weight, offsetting the severe decline expected at Fox Complex.
Accelerating. Represents a solid increase from 58,120 GEOs in 2025. Management expects this asset to generate $50M+ in dividends to MUX in 2026 under the new 90% free cash flow payout policy, serving as the company's financial backbone.
Stable. The guided range is effectively flat compared to the 2025 actual of $2,444/oz. Cost inflation in Argentina and high capital intensity at Fox/Gold Bar are offsetting the benefits of higher production volumes.
Key Questions
Fox Complex Bridge Plan
With Fox Complex production dropping to 16k-19k GEOs in 2026 and AISC projected at $2,650-$2,850/oz, how will management prevent this asset from burning cash before the Stock mine achieves commercial production in 2027?
Los Azules Funding Structure
With the Feasibility Study complete and FID targeted for year-end 2026, what is the exact mechanism for funding MUX's share of the $3.2B initial Capex? Is an IPO of McEwen Copper still the primary vehicle?
Cost Control Levers
AISC is cemented above $2,400 globally. Aside from hoping metal prices stay at record highs, what tangible operational levers are being pulled to structurally reduce costs across the 100%-owned portfolio?
