Cabral Gold Pours 1,130 oz at Cuiú Cuiú, Beating Projections

Cabral Gold Inc. poured its first gold at the Cuiú Cuiú district in Pará state, Brazil on 10 September 2026, producing approximately 1,130 ounces of gold doré and beating the company’s own internal projections. Overnight, Cuiú Cuiú became one of Brazil’s newest producing gold mines.

The pour marks the hinge point in Cabral’s story: the shift from developer to junior producer. Construction finished roughly two months ahead of the original schedule, and financing had been locked in about a year earlier, setting up a commissioning run that has, so far, moved faster than planned.

But the first pour is a stage-gate, not a finish line. Here is where the operation actually stands, and the specific milestones that will define whether this becomes a commercial-scale mine over the next several weeks.

First pour beats projections as Cuiú Cuiú completes its dry-to-wet transition

The number arrived ahead of expectations. Cabral’s inaugural doré pour on 10 September 2026 delivered roughly 1,130 ounces of gold at an estimated 93-94% purity, exceeding the company’s internal projections for the commissioning batch.

That figure matters most for what it confirms: the process works. But it sits inside a staged commissioning sequence that is not yet complete, and understanding what “first pour” covers is the difference between reading this as a milestone and misreading it as a destination.

Heap leach operations commission in two broad circuits. The dry circuit covers mining, crushing, and stacking ore onto the leach pad. The wet circuit covers the leaching itself and the ADR (adsorption, desorption, and recovery) plant that pulls gold out of solution and into doré.

Here is where each stood at the time of reporting:

• Dry circuit (mining, crushing, stacking): commissioning complete
• Wet circuit and ADR plant: nearing completion, expected to reach full completion within roughly one week of the first pour
• Stacking rate ramp-up toward the 3,000 tonne-per-day design target: ongoing, expected to span several more weeks

One early operational signal stood out. Oxide material on the inaugural pad is dissolving faster than laboratory testwork had predicted, which, alongside the above-projection pour volume, points to encouraging metallurgical performance in these opening cycles.

The faster-than-expected oxide dissolution at Cuiú Cuiú reflects the material characteristics of the ore body, but heap leach gold recovery rates across the industry are also being shaped by advances in micro-fracturing and blasting design that improve solution contact with ore before stacking.

“The first pour exceeded our internal projections,” said Alan Carter, President and Chief Executive Officer of Cabral Gold, characterising the commissioning result as ahead of the company’s own expectations.

The caution worth holding: these are readings from a single leach cycle. Faster dissolution and a strong first pour are genuine positives, but they do not yet confirm long-term heap recovery rates. As of the 9 July 2026 update, commissioning was around 85% complete with more than 90% of project costs committed, so the financial commitment is largely made. What remains outstanding is assay confirmation and wet-circuit stabilisation before the operational picture is whole.

What the PFS economics require from ramp-up, and where the operation stands now

A first pour is not commercial production, and the gap between the two is measured in specific, crossable thresholds rather than an abstract journey to steady state.

Cabral has defined commercial production internally as reaching 60-70% of design throughput, targeted for Q4 2026. The design capacity itself is 3,000 tpd (roughly 1 Mtpa), and the operation is approaching it incrementally as stacking rates climb.

The prefeasibility study, updated 29 July 2025, sets the benchmark that ramp-up has to validate. These are not aspirational numbers; they are the figures the operation must reproduce in the field to justify the producer thesis.

Over the initial 6.2-year mine life, the PFS models around 113,155 ounces of gold, a projected internal rate of return of 78%, and annual pre-tax cash flow near US$75 million. Those returns depend on the operation reproducing PFS grades and recoveries at scale, which is precisely what the coming weeks test.

One constraint sits directly in the path. The current trial-mining licence caps throughput at 500,000 tpa, well below the 1 Mtpa design target. Cabral cannot reach full PFS-projected cash flow without a full mining licence, so treat that cap as an active constraint on the ramp-up, not a paperwork formality.

The gold loan structure and what it means for ramp-up urgency

The financing gives these milestones teeth. Cabral’s operation is funded largely through a gold loan requiring fixed quarterly deliveries of physical gold.

That structure means commissioning performance carries direct cash obligations, not just share price optics. The mine has to pour enough ounces on schedule to meet repayment, which turns recovery rates and throughput from operational metrics into financial ones.

Underperformance in recoveries or throughput would compress margins and, according to commentary from Flash StockSentinel, challenge the self-funded Phase 2 narrative that much of the current thesis rests on.

Three risks that will determine whether commissioning results hold

Not every risk carries the same weight or the same timing. Sequenced by proximity, the nearest challenge is operational, and the outer layers are weather and permitting.

The most immediate uncertainty is the wet circuit. As of reporting on 13 September 2026, the wet circuit and ADR plant were expected to reach completion roughly one week after the first pour, and stabilising solution chemistry and recovery through this circuit is the near-term operational hurdle.

Weather is the next layer. Cuiú Cuiú sits in the Amazonian Tapajós region, where tropical rain complicates heap leach engineering across pad drainage, liner integrity, solution chemistry management, and the need for adequate ponds to absorb rainfall events. Heavy rain can also blunt stacking efficiency during the ramp-up.

The outer layer is permitting. The 500,000 tpa trial-mining cap sits below the 1 Mtpa design target, and a full mining licence is required before the operation can scale up without restriction.

The permitting constraint at Cuiú Cuiú sits inside a broader friction point: Brazilian gold legislation has been contested by mining companies in 2026, with new regulatory frameworks adding uncertainty to licence timelines across the sector.

• Operational and metallurgical: wet-circuit and ADR plant stabilisation, plus recovery validation across multiple leach cycles
• Weather and tropical pad management: rainfall effects on stacking, pad drainage, liner integrity, and solution chemistry
• Permitting and throughput cap: 500,000 tpa trial-mining limit versus 1 Mtpa design, pending a full mining licence

Beneath all three sits a validation gap. A first pour proves the flowsheet functions; it does not prove long-term heap recovery. Several leach cycles of data are needed before mined grade can be reconciled against recovered gold.

“A first pour proves the flowsheet, not the recoveries,” observed commentary published by the Silver Sofa Substack on 10 September 2026, noting the first gold came from ore stacked only a single leach cycle earlier.

Assay results from the first doré were still outstanding at the time of reporting, and management flagged several additional weeks before full reconciliation is possible. For investors, that outstanding data is a live uncertainty rather than a red flag. The next material data point is not another headline announcement; it is the operational data that emerges from sustained heap leach cycling over the coming weeks, so silence before that window closes should not be read as bad news.

Resource base and market reaction set the stage for Phase 2

The market moved on the news, and it moved from a position that had already anticipated success.

• TSXV: shares rose 5.4% (C$0.08) to C$1.56, near the top of a 52-week range of C$0.38-C$1.59
• OTCQX (CBGZF): around US$1.11, up roughly 3% on 11 September 2026
• Analyst target: Stifel’s Ryan Walker initiated coverage with a Buy rating and C$1.70 price target on 25 August 2026
• Market capitalisation: approximately C$407.4 million, per the Globe and Mail on 4 September 2026

Trading near a 52-week high on pour day, with an analyst target barely above the current price, tells you the market has largely priced in commissioning success. The next re-rating event is more likely to be sustained commercial production data than the milestone announcement itself. The producer re-rating thesis that Walker’s pre-pour note anchored has now been partially, not fully, validated.

Underneath the oxide starter operation sits the strategic prize: a much larger, higher-grade hard-rock resource base.

Total Indicated resources sit near 666,000 oz and Inferred near 526,000 oz, with the higher-grade fresh basement material forming the strategic rationale for Phase 1’s low-capex approach. The oxide heap leach is explicitly a starter operation, backed by a C$45 million strategic investment from Alpayana, and a Phase 2 preliminary economic assessment is targeted for the first half of 2027 in analyst commentary. Understanding that resource scale is how you gauge whether Phase 1’s cash-flow profile justifies the current valuation, and what a Phase 2 unlock could mean across the district.

The Cuiú Cuiú resource table separates Indicated from Inferred material across oxide and fresh basement domains, and mineral resource classification determines how much weight investors can place on each category when modelling Phase 2 economic potential.

What a confirmed commercial production declaration would change for Cabral

The question has shifted. It is no longer whether Cabral can pour gold; the doré bar answered that. It is whether the company can sustain throughput, hit recovery rates matching the PFS, and clear the permitting step that unlocks full-scale production, and each answer arrives on its own timeline.

Here is the sequence worth tracking:

1. Wet-circuit completion (expected roughly one week after first pour) and assay results from the first doré
2. Sustained stacking rates approaching 3,000 tpd
3. Q4 2026 commercial production declaration at 60-70% of design throughput
4. Full mining licence application and grant, removing the 500,000 tpa cap
5. Phase 2 PEA, targeted for the first half of 2027

No formal annual production guidance has been issued for 2026, with 2027 guidance expected once ramp-up is substantially complete. Knowing this sequence lets you calibrate your monitoring cadence rather than reacting to each announcement in isolation.

Phase 1 as the funding engine for Phase 2 hard-rock development

The strategic premise is simple: Phase 1 oxide cash flow funds Phase 2 hard-rock development without further equity dilution. That is the oxide-bridge thesis investors are holding.

What would undermine it is equally specific: recovery rates falling short of the PFS, gold loan delivery obligations going unmet, or permitting delays stalling the scale-up. Any one of those would compress margins and challenge the self-funding story.
