Is EXK a Buy? What to Consider in 2026
Short answer
The bull case for Endeavour Silver (EXK) rests on Terronera ramp-up: Terronera, Endeavour's flagship growth project in Jalisco, Mexico, achieved commercial production effective October 1, 2025 and ramped to consistently exceed about 90% of its 2,000-tonnes-per-day nameplate capacity. Revenue (2025 full year) is ~$467.5 million, a record, up ~115% over 2024. If you believe that thesis holds, the real questions become position sizing and overlap, not timing. The main risk to that view: Endeavour Silver's results are highly cyclical and move with the silver price, which is volatile and outside the company's control, so margins and the share price can swing sharply, and gold byproduct prices add another moving part. Whether EXK is a buy comes down to whether you believe the thesis. This is informational, not a recommendation, and Walnut is not an investment adviser.
Endeavour Silver Corp (EXK) is a Vancouver-based mid-tier precious-metals mining company focused primarily on silver, with meaningful gold byproduct. It makes money by extracting ore from its underground mines, processing it into silver and gold, and selling that metal at prevailing market prices, so its revenue and margins are driven by how many ounces it produces relative to its mining costs and by where the silver and gold price sit. Its core producing assets are the Guanacevi mine in Durango, Mexico, the newly commissioned Terronera mine in Jalisco, Mexico, and the Kolpa mine in Huancavelica, Peru, which it acquired in 2025. In 2025 the company produced about 11.2 million silver-equivalent ounces and reported record annual revenue of $467.5 million. Endeavour has operated in Mexico for years, historically running the Guanacevi and Bolanitos mines, and its recent story is one of transformation through growth. Terronera, its largest capital project, achieved commercial production effective October 1, 2025 and ramped to consistently exceed roughly 90% of its 2,000-tonnes-per-day nameplate capacity, marking a step-change in scale. In 2025 the company also expanded internationally by acquiring the Kolpa mine in Peru for about $145 million, adding a third producing asset and an estimated 5 million silver-equivalent ounces of annual output, while agreeing to sell its smaller Bolanitos mine to Guanajuato Silver for up to $50 million in a deal expected to close in January 2026. The company is also advancing the Pitarrilla development project and strengthened its balance sheet with a $350 million convertible debt offering in December 2025.
What's the case for buying EXK?
1. Terronera ramp-up.
Terronera, Endeavour's flagship growth project in Jalisco, Mexico, achieved commercial production effective October 1, 2025 and ramped to consistently exceed about 90% of its 2,000-tonnes-per-day nameplate capacity. Higher-grade zones are scheduled to be accessed through 2026, which management expects to lift grades and output in the second half of the year. A successful, sustained ramp to full rates is the single biggest driver of the company's near-term production and cost trajectory.
2. Silver-price leverage.
As a producer with relatively fixed mining costs, Endeavour's profits rise and fall more than proportionally with the silver price, with gold byproduct adding to that mix. Higher metal prices and rising volumes drove record 2025 revenue of $467.5 million, up about 115% year over year. That operating leverage cuts both ways, amplifying results when silver rallies and compressing margins sharply when it falls.
3. Production growth and diversification.
Full-year 2025 silver-equivalent production rose about 48% to 11.2 million ounces, helped by Terronera and the Kolpa acquisition. For 2026 the company guides to 14.6 to 15.6 million silver-equivalent ounces from Guanacevi, Terronera, and Kolpa, roughly 8.3 to 8.9 million ounces of silver plus 46,000 to 48,000 ounces of gold. Spreading output across Mexico and Peru reduces reliance on any single mine.
4. Cost normalization.
Costs spiked during the Terronera ramp, with Q4 2025 all-in sustaining costs reaching $41.19 per ounce amid startup inefficiencies and a stronger Mexican peso. Management guides consolidated 2026 AISC down to roughly $27.00 to $28.00 per ounce net of byproduct credits, with cash costs of about $12.00 to $13.00 per payable silver ounce. Hitting those targets depends on Terronera reaching steady-state grades and throughput.
What are the risks to EXK?
Endeavour Silver's results are highly cyclical and move with the silver price, which is volatile and outside the company's control, so margins and the share price can swing sharply, and gold byproduct prices add another moving part. Jurisdictional and political risk is significant because its mines sit in Mexico and Peru, both of which carry permitting, tax, labor, and resource-nationalism risk. Execution risk on the Terronera ramp is real, as shown by the elevated Q4 2025 AISC of $41.19 per ounce during startup, and the planned cost normalization to roughly $27 to $28 per ounce in 2026 depends on reaching design grades and throughput. Cost inflation, a stronger Mexican peso, and integration of the Kolpa acquisition add further uncertainty, and the company reported a 2025 net loss of $119.1 million driven largely by derivative losses and higher finance costs.
How is EXK valued? (as of FY2025 results (reported early 2026) and 2026 guidance)
- Silver-equivalent production (2025): ~11.2 million ounces, up ~48% year over year
- Revenue (2025 full year): ~$467.5 million, a record, up ~115% over 2024
- Net income (2025): net loss of ~$119.1 million, driven largely by ~$126 million of derivative losses and higher finance costs
- All-in sustaining costs: Q4 2025 AISC ~$41.19 per ounce during the Terronera ramp; 2026 guidance ~$27 to $28 per ounce net of byproduct credits
- Cash: ~$215 million as of December 31, 2025 (~$232 million at March 31, 2026), aided by a $350 million convertible debt raise
- Market cap: ~$2 billion to $3 billion, varying with the silver price and share price
A silver producer's numbers are commodity-driven: revenue, earnings, and valuation are dominated by the silver price (plus gold byproduct) and by how many ounces the company produces relative to its costs. All-in sustaining cost (AISC) per ounce is the key margin gauge, and it spiked at Terronera during startup before management guided it down for 2026 as the mine ramps. Because metal prices are cyclical and volatile, a silver miner's profits and share price can swing far more than the underlying metal, and headline figures like a net loss can be distorted by non-cash items such as derivative revaluations rather than the underlying mining business.
How do you decide if EXK is a buy?
Rather than asking whether EXK is a buy in the abstract, it tends to help to answer four questions:
- Thesis: do you believe the case above, and is it still true today?
- Time horizon: a single stock can be volatile, so a longer horizon absorbs more of the swings.
- Position sizing: a thesis can be right and the sizing still wrong; decide how much of your portfolio one name should be.
- Overlap: check whether you already hold EXK indirectly through an index or sector ETF before adding more.

The bottom line on EXK
The bottom line: Endeavour Silver's story right now is Terronera ramp-up, with revenue (2025 full year) at ~$467.5 million, a record, up ~115% over 2024. If you believe that narrative continues, the call is about sizing EXK sensibly and checking overlap with what you own; if you doubt it (the risk: endeavour Silver's results are highly cyclical and move with the silver price, which is volatile and outside the company's control, so margins and the share price can swing sharply, and gold byproduct prices add another moving part.), it is not for you. Decide from the thesis, not the ticker. Walnut is not an investment adviser.

What are the main risks of EXK?
+
Endeavour Silver's results are highly cyclical and move with the silver price, which is volatile and outside the company's control, so margins and the share price can swing sharply, and gold byproduct prices add another moving part. Jurisdictional and political risk is significant because its mines sit in Mexico and Peru, both of which carry permitting, tax, labor, and resource-nationalism risk. Execution risk on the Terronera ramp is real, as shown by the elevated Q4 2025 AISC of $41.19 per ounce during startup, and the planned cost normalization to roughly $27 to $28 per ounce in 2026 depends on reaching design grades and throughput.

What does Endeavour Silver do?
+
Endeavour Silver is a Canadian-based mid-tier precious-metals mining company that produces and sells silver and gold. It operates underground mines in Mexico (Guanacevi and the newly commissioned Terronera) and Peru (the Kolpa mine acquired in 2025), and it is advancing the Pitarrilla development project. It makes money by mining ore and selling the recovered metal at market prices.
Does EXK pay a dividend?
+
No. Endeavour Silver does not currently pay a dividend. Management has said it is focused on growth and development, including the Terronera ramp and the Pitarrilla project, rather than returning cash through dividends, so investors in EXK are relying on share-price appreciation rather than income.
What is the Terronera mine and why does it matter?
+
Terronera is Endeavour's largest capital project, an underground silver-gold mine in Jalisco, Mexico. It achieved commercial production effective October 1, 2025 and ramped to consistently exceed roughly 90% of its 2,000-tonnes-per-day nameplate capacity. It matters because it is the single biggest driver of the company's production growth and its path to lower all-in sustaining costs in 2026 and beyond.
Why is EXK considered leveraged to the silver price?
+
Because mining costs are relatively fixed, a producer's profits move more than proportionally with the metal price. When silver rises, a larger share of the higher price flows straight to margins, and when silver falls, margins compress quickly. That operating leverage is why EXK shares often move more sharply, up and down, than the silver price itself.
