Endeavour Silver’s Output Doubles Into a Structural Silver Deficit

Endeavour Silver has roughly doubled its silver-equivalent output in three to four years, moving from about 7 million ounces to a projected 15 million this year. That pace of expansion arrives at a moment when the global silver market is running a structural deficit and almost no primary producers have meaningful production growth left to offer.

That combination is rarer than it sounds. Most silver reaches the market as a by-product of lead, zinc, copper, and gold mining, so a dedicated primary silver company carrying an embedded, multi-phase growth pipeline sits in a category with very few members. For an investor wanting direct, leveraged exposure to silver’s supply-demand imbalance rather than a diluted slice of a base-metal miner, the options are limited.

This piece gives you a structured way to separate what is already happening at the asset level from what remains speculative. By the end, you will be able to form a view on how much weight to assign to Endeavour Silver’s stated growth trajectory when you make a position decision, and which catalysts would move the balance either way.

From 7 million to 18 million ounces: how Endeavour Silver’s output nearly doubled

The trajectory reads as a clean arc. Roughly 7 million silver-equivalent ounces a few years ago, approximately 15 million targeted for full-year 2026, and a forecast of 17-18 million ounces in 2027 once its two newest contributors run for a full year.

The clean arc hides a more useful truth. This growth did not come from a single catalyst; it came from three distinct moves stacked on top of a stable base.

The first was the Kolpa acquisition in Peru, later expanded to 2,500 tonnes per day. The second was Terronera, a new mine in Mexico now ramping up. The third is Guanaceví, the long-standing operational base that keeps producing while the newer assets grow into their capacity.

The Q2 2026 operating data, from the quarter ended 30 June 2026, shows the machine actually running rather than management forecasting.

A 68% throughput increase year-on-year is the single figure that frames this section. It tells you the output gains are operational, not a function of silver’s price.

That distinction matters when you assess the credibility of the 2027 forecast. Revenue reached approximately US$212 million in Q2 2026, a 149% year-on-year surge per Streetwise Reports (5 August 2026). A revenue jump of that size can flatter a company when metal prices rise, but you cannot fake a 68% increase in tonnes fed through a mill. The physical throughput growth is what makes the 17-18 million ounce target for 2027 look like a plan being executed rather than an aspiration being marketed.

What the asset-level numbers actually tell you about near-term risk

The headline forecast only means something once you know which assets carry it. Walk through Kolpa and Terronera in turn and the reason analysts treat the 2027 number as the more credible part of the growth plan becomes clear.

Kolpa: capacity already installed, contribution still ahead

Kolpa expanded from 1,700 tpd to 2,500 tpd and has been running at the higher rate since March 2026. In Q2 2026 it processed 233,408 tonnes and produced 633,288 oz of silver, up 66% year-on-year.

The timing is the point. Because the expanded capacity only came online partway through 2026, a full year at the new rate lands in 2027, not this year. That is a large slice of the 2027 uplift already sitting inside operational reality rather than management projection.

A new resource estimate for Kolpa is expected by the end of 2026. There is also a contingent payment of US$10 million owed to the previous owner if the resource reaches 120 million oz of silver, due by May 2027. Management has said it fully expects to make that payment, which reads as a quiet signal of internal confidence in where the resource number will land.

Terronera: a ramp-up with a growing exploration record

Terronera contributed 608,347 oz of silver and 7,666 oz of gold in Q2 2026 while still ramping. Drilling there, paused during construction, has resumed with roughly 20 holes completed and 10 disclosed publicly, all described as extending the high-grade zone. Deep-zone drilling is underway.

Here is a scannable catalyst calendar for the near term:

• Kolpa new resource estimate, expected by end of 2026
• Terronera deep-zone drilling, results emerging progressively
• Guanaceví drill results from earlier in 2026, due for publication in Q4 2026

With Kolpa already at expanded capacity and Terronera building an exploration track record, the 2027 forecast rests on demonstrated throughput rather than promises alone. That is the difference that should shape how much discount you apply to the number: less than you would for a pure projection, more than you would for a fully mature operation.

Pitarrilla and the case for primary silver exposure in a deficit market

Everything above is near-term. Pitarrilla is the long game, and it is where the scale of the opportunity and the weight of the uncertainty sit side by side.

Start with why a company like this is uncommon. According to the Silver Institute, most global silver supply arrives as a by-product of lead, zinc, copper, and gold mining, with primary silver mines a minority of total output. A dedicated primary producer with a genuine development pipeline therefore carries scarcity value in a sector where silver is usually an afterthought on someone else’s balance sheet.

That scarcity matters more in the current market. The Silver Institute describes a structural deficit environment, with rising industrial demand from photovoltaics, electronics, and automotive electrification underpinning the imbalance. Incremental primary silver supply is worth more, strategically, than an equivalent trickle of by-product metal.

The silver supply deficit has persisted across five consecutive years according to Silver Institute data, with industrial drawdowns from photovoltaics and electronics consistently outpacing mine supply growth and recycling contributions.

Pitarrilla is where that framing meets a single large asset.

Pitarrilla is described as hosting approximately 600 million oz of silver, plus lead and zinc, placing it among major silver deposits on a global scale.

Now the pivot. Almost every headline figure above carries a qualifier. The mill capacity, the capex, and the 7 million ounce contribution are all management estimates, not study-confirmed numbers. Management characterised its expectation of the feasibility study as “very positive,” and the study was expected by the end of Q3 2026 per the corporate presentation dated 9 September 2026. As of this writing, no completion announcement has been publicly confirmed.

That is the central thing to hold. Pitarrilla’s value to the investment case is real, but it is not yet measurable with precision. The US$500-600 million cost and the 7 million ounce contribution are the difference between a company with a strong near-term ramp and one that could become a genuinely large-scale primary silver producer. Until the study lands, you are sizing a possibility, not a plan.

What the risks actually look like across the 2027-2030 timeline

The production arc is optimistic. The risk layer is where you turn that optimism into something you can actually monitor. These are not generic caveats; each one has an observable signal attached.

Split them by timeline. The near-term risks:

• Terronera and Kolpa ramp-up execution, where any stumble delays the 2027 target
• Epithermal vein grade variability, where geological models can prove optimistic
• Cost absorption, evidenced by Q2 2026 adjusted EPS missing consensus despite strong top-line growth

That EPS miss deserves a moment. It reflects a growth phase absorbing elevated capital and operating leverage, not an operational failure. Reading it as underperformance would be a mistake; reading it as the cost of building two contributors at once is closer to the mark.

The longer-dated risks cluster around Pitarrilla, and they arrive roughly in this order:

1. Permitting and social licence. The shift from a historical open-pit concept to an underground high-grade-core mine reflects attention to environmental and social constraints in Mexico. Watch community relations disclosures.
2. Financing capacity. With capital already committed to Kolpa and Terronera, a US$500-600 million project needs internal cash, equity, debt, or a mix. Watch balance sheet capacity as the two newer mines ramp their cash flow.
3. Feasibility outcomes. The cost figure is a management assumption until the study lands. Watch the delta between the actual number and the estimate; the size of the gap will tell you more than the number itself.
4. Construction execution. A plant of this scale would be a step change in Endeavour’s operating footprint, bringing ramp-up and overrun risk.

Mining project financing structures for a development of Pitarrilla’s scale typically blend internal cash flow, project-level debt, royalty streams, and equity to manage the timing mismatch between capital outflows and production-phase returns, with the relative weight of each instrument affecting both dilution risk and the conditions attached to drawdown.

Two structural points sit underneath all of this. Silver price movements feed directly into NPV, payback, and financing terms, so the Pitarrilla case is not independent of the price at the time of any final investment decision. And because epithermal veins are narrow, structurally complex, and discontinuous, the whole portfolio requires continuous exploration and incremental resource replenishment, sustaining ongoing capital needs beyond what a bulk-tonnage mine would demand.

Making a position decision on a silver producer at a strategic inflection point

There are two investment cases inside this one company, and separating them is the practical takeaway.

The near-term case rests on Kolpa and Terronera delivering 17-18 million silver-equivalent ounces in 2027 into a structurally tight silver market. Operational results are steadily retiring the risk on that number.

The longer-dated case rests on Pitarrilla eventually adding roughly 7 million silver-equivalent ounces from around 2030 and transforming the company’s scale. That case still carries the weight of a management estimate rather than a confirmed plan.

Here is the catalyst calendar to monitor, in sequence:

1. Kolpa resource estimate, end of 2026
2. Guanaceví drill results, Q4 2026
3. Pitarrilla feasibility study publication, expected post-Q3 2026, still pending
4. Kolpa contingent payment confirmation, May 2027 trigger
5. Terronera full-year throughput confirmation through 2027

The feasibility study is the one that matters most. When Pitarrilla’s cost moves from a management assumption to a study-confirmed figure, the market can finally price its contribution with a precision that is impossible today.

The near-term production story is increasingly de-risked by operational results. The 2030 story is real, but it still carries the weight of a management estimate rather than a confirmed plan. Weight Pitarrilla as optionality, not confirmed production, until the study lands and a final investment decision is made.

Evaluating mining management credibility is particularly important when a company’s near-term numbers are strong and the forward projections are ambitious, because management teams skilled at operational execution and management teams skilled at capital allocation are not always the same people.

The silver market’s structural deficit raises the value of every incremental primary ounce, but it does not erase asset-specific execution risk.
