Why Integra’s Florida Canyon Costs Rose Even as Output Climbed

#

Gold is trading near $4,358 per troy ounce, one of the strongest price environments Florida Canyon has ever operated in. Yet the mine-site all-in sustaining cost (AISC) ran above $3,300 per ounce for two consecutive quarters in 2026, and Integra Resources lifted its full-year cost guidance by roughly $500 per ounce. That gap between record gold prices and a rising unit cost trajectory is the puzzle worth solving.

Florida Canyon is the operational foundation that funds Integra’s broader growth strategy, which makes its 2026 performance the deciding factor in whether the mine-life extension thesis is a credible re-rating catalyst or a high-cost transition story with unresolved execution risk. The revised guidance, a 30% quarter-over-quarter production recovery, and a 50,000-metre drilling program are all landing at the same moment in the mine’s life cycle.

What Q1 and Q2 2026 actually reveal about the turnaround’s progress

The first two quarters of 2026 sent two signals at once, and they pointed in opposite directions.

The production signal was genuinely encouraging. Q2 2026 gold output reached 16,379 oz, a 30% increase over the prior quarter, driven by record total material movement and record ounces stacked on the heap leach pads. Expanded haulage capacity let Integra move more ore and strip more waste than in any prior quarter. On throughput alone, the operation was clearly finding its footing.

The cost signal complicated that story. Mine-site AISC came in at $3,310 per ounce in Q1 and actually ticked higher to $3,371 per ounce in Q2, even as production climbed 30%. Cash costs followed the same path, rising from $2,422 per ounce to $2,495 per ounce.

The upward drift in cost per ounce despite a 30% production gain tells you something important: the cost pressure at Florida Canyon is not simply a volume problem. If it were, higher throughput would have diluted fixed costs across more ounces and pulled AISC down. It did not. That is why the guidance itself moved.

Revised 2026 mine-site AISC guidance: $3,300-$3,500 per ounce Up from the original $2,750-$2,950 per ounce issued on 23 February 2026, revised on 25 June 2026.

Management reconfirmed production guidance at 70,000-75,000 oz for the year even as it lifted the cost band, and it now estimates that roughly 90% of core operational problems have been resolved as of September 2026. Hold that figure carefully. It means the production trend is directionally correct, and it also means about 10% of identified issues remain open, precisely at the point where higher throughput has not yet translated into lower unit costs the way a clean recovery would predict.

Why heap-leach blending and haulage became the dominant cost and technical driver

The root cause traces back to a problem that sounds logistical but behaves chemically: ore blending. High fine particle content in stockpiled low-grade material plugged the pore spaces in the heap leach pad, and that single failure mode cascaded into recovery and cost outcomes that took roughly two years to bring under control.

Here is the mechanism. A heap leach pad works by trickling a leach solution through stacked crushed ore to dissolve the gold. When fine particles and clay migrate downward and laterally through the heap, they clog the gaps between larger fragments and form low-permeability layers.

Solution then stops percolating evenly. It channels around the blocked zones, bypasses ore, and leaves gold trapped where the liquid never reaches. Recovery falls, and cost per recovered ounce rises.

Agglomeration binders in heap leaching are one of the most direct technical responses to the fine-particle permeability problem, binding crushed ore into stable granules that resist migration through the heap and maintain solution flow channels across multiple lift layers.

This is why haulage is not merely a transport function at Florida Canyon. According to George Salamis, President and Chief Executive Officer of Integra Resources, material haulage logistics represent a dominant cost and technical driver of the operation’s heap-leach economics. Routing material from pit to crusher or directly to the pad determines the blend that lands on the heap, which in turn determines whether the pad drains freely or clogs.

Management now reports that improved blending strategies are in place and that the earlier permeability issues have been resolved. The upcoming central ore is expected to carry better leach kinetics and lower fine particle content, which should lift recovery rates and lower unit costs. Whether that expectation holds is the real test of the 90% resolution claim.

Industry best practices for managing fines and permeability in Nevada heap-leach operations

Nevada operators have developed a well-established toolkit for keeping fine-rich ore free-draining. According to the SME Mining Engineering Handbook and technical work by Kappes, Cassiday & Associates, the core techniques are:

• Agglomeration with cement or lime binders, which bind crushed ore into stable granules so fines cannot migrate and plug the heap.
• Crush-size optimisation using column leach tests, balancing finer crushing for gold liberation against coarser crushing for permeability.
• Ore blending at the crusher or stockpiles, mixing high-clay feed with coarser material to keep feed characteristics consistent.
• Lift thickness and stacking pattern control, using thinner lifts and systematic stacking to spread solution evenly.
• Solution monitoring via piezometers and lysimeters, tracking solution levels to catch ponding and channeling before recovery suffers.

For an investor weighing execution risk, the blending resolution matters because the same fine-particle and permeability dynamics could recur with the central ore if its texture differs from what management expects. The techniques above are how Nevada producers prevent that. Whether Integra applies them cleanly to a new ore type is what determines if the projected recovery gain is real or optimistic.

What 50,000 metres of drilling is designed to prove about mine life

The drilling program is not a routine exploration update. It is a specific argument Integra is putting to the market: that material previously mapped as waste in the saddle zones between existing pits is actually ore, and that validating this reclassification changes both the mine life and the cost economics.

The logic is direct. Converting saddle-zone waste to ore eliminates the transportation cost of hauling that material to a dump, because it becomes feed rather than a liability. Margins on that tonnage improve, and the reserve base extends.

The scale of the commitment has grown through the year, which is itself a signal. The program began with an initial target near 33,500 metres, expanded to 42,500 metres, and most recently reached a 50,000-metre full-year target in September 2026 CEO commentary, with approximately 30,140 metres of reverse circulation drilling completed.

The mine-life thesis anchors to the updated Feasibility Study, which carried an April-May 2026 effective date and incorporated 100,118.5 feet across 649 drill holes with 18,375 assay intervals, drawn from a total Florida Canyon database of 5,470 holes. That depth of data is what gives the central ore plan its footing.

The program’s expansion from 33,500 to 50,000 metres inside a single calendar year tells you early results were encouraging enough to justify accelerating capital spend. It does not tell you the thesis is proven. The mine-life extension is not investable until saddle-zone material converts from a geological observation into a proven reserve in a subsequent technical report.

Nevada precedent sets the timeline for that conversion:

1. SSR Mining’s Marigold has repeatedly extended heap-leach life by converting inter-pit and saddle-zone waste to ore across successive technical reports.
2. Kinross Round Mountain relies on pit-extension and inter-pit drilling to keep oxide reserves growing as drill spacing tightens.
3. Coeur Rochester has used near-mine drilling between pits to justify major pad and plant expansions.

Across these operations, the cycle from focused drilling to recognised reserve impact typically runs two to five years. That places meaningful validation for Florida Canyon’s saddle zones into 2027-2028 at the earliest, and it is the gap between drilling result and reserve conversion where most mine-life stories either gain or lose credibility.

The gold price windfall that is also a cost headwind

There is a comfortable assumption buried in most Florida Canyon commentary: that a stronger gold price is unambiguously good news at the mine-site level. In 2026, that assumption is only partly true.

Spot gold was trading near $4,357.90 per troy ounce as of 22 September 2026, one of the strongest environments in the mine’s modern operating history. The revenue benefit is real. But Nevada’s royalty and excise tax framework converts part of that price strength directly into higher mine-site cost.

The mechanism is structural. Royalties and excise taxes at Florida Canyon are tied to metal prices, so as gold rises, the per-ounce charge against production rises with it. Integra’s Q1 and Q2 2026 results explicitly cited higher royalties and excise taxes from strong metal prices as a direct contributor to elevated AISC.

Royalties and excise taxes tied to metal prices represent one structural cost layer that many investors underweight when evaluating gold miner AISC margins, because the same price strength that expands revenue simultaneously lifts per-ounce charges against production.

That is why the cost guidance revision to $3,300-$3,500 per ounce is not a single-cause event. It reflects three distinct pressures:

Royalties and excise taxes are not the only price-linked cost input at open-pit operations like Florida Canyon; diesel cost exposure in Nevada mining scales with both the volume of material moved and fuel market conditions, and record material movement in 2026 amplified both dimensions simultaneously.

• Royalties and excise taxes driven higher by gold price strength, a structural effect that scales with the metal price.
• Record tonnes mined and waste stripping, a capital-intensity effect tied to the current transition phase.
• Heap leach pad expansion accelerated to 2026, brought forward to accommodate record tonnage volumes.

The first is structural and persists as long as gold prices stay high. The second and third are transition costs expected to normalise once central ore dominates the feed from 2027 onward, when management targets 80,000-85,000 oz per year at improved unit economics.

The institutional read: “high-beta, high-execution-risk.” Many institutional investors treat Florida Canyon as an asset with attractive upside if the mine plan delivers, but with enough operational risk to justify cautious valuation multiples until several more quarters of performance and reserve conversion are demonstrated.

Here is what this means for how you size the position. The royalty mechanism means Florida Canyon’s net margin expansion from gold price upside is smaller than a simple gold-price-times-ounces calculation would suggest. The gold price provides margin insulation during the high-cost transition, but it also caps part of the upside a naive AISC-versus-spot-price spread would project. Execution on tonnage, grade, and recovery matters more to the valuation outcome than the gold price trajectory itself.

The variables that will determine whether Florida Canyon re-rates or stalls

The cautious institutional prior is rational. Given the revised guidance and the two-year heap-leach technical history, demanding several more quarters of demonstrated performance before assigning full valuation credit is the defensible position.

The institutional caution on Florida Canyon reflects a broader principle: operational quality in miner selection matters more during a gold rally than in flat or declining price environments, because elevated prices amplify both the margin upside of well-run operations and the cost exposure of operations still working through transitions.

It is also true that Florida Canyon’s 2026 is consistent with a well-documented pattern. Nevada heap-leach transitions produce a cost hump, where site-level AISC peaks while stripping is high and capital is being deployed, then trends lower as ore grades rise and sustaining capital normalises. Integra’s guidance revision while holding production guidance fits that pattern precisely. But consistency with a pattern is not a guarantee that the pattern completes.

So the analytical work is not finished after one or two quarters of improved throughput. The real question is whether AISC begins bending down meaningfully by mid-2027 as central ore replaces stockpile feed.

Four milestones to track before revising the Florida Canyon thesis

1. Q3 2026 AISC trajectory. A downward move signals cost pressures are easing as the operation stabilises; a further rise signals structural cost issues beyond the transition are still in play.
2. Saddle-zone resource update timing and grade. A formal update converting waste to ore at credible grades would validate the mine-life thesis; a delay or weak grades would push the re-rating case further out.
3. 2027 production from central ore versus the 80,000-85,000 oz target. Hitting the target confirms the higher-grade transition is working; falling short signals the metallurgy or grade assumptions were optimistic.
4. AISC response once central ore dominates the feed. A meaningful decline confirms the cost hump was temporary; a sticky AISC above $3,300 would suggest the cost structure is more permanent than the transition thesis assumes.

Reserve conversion, on Nevada precedent, runs two to five years from focused drilling, and the typical analyst judgment window for these transitions is 12 to 24 months. That timeline is your evaluation frame, not management commentary alone.

What the Florida Canyon story tells you about the gap between turnaround momentum and turnaround completion

The analytical arc resolves into a distinction worth holding precisely: directional improvement is visible, but structural improvement still requires demonstrated performance.

Three threads carry that distinction. The operational cost hump is partly structural, through royalties that scale with the $4,358 gold price, and partly temporary, through the capital intensity of record tonnage and pad expansion. The heap-leach technical resolution is credible, with management reporting 90% of problems resolved, but the recovery gain from central ore must still show up in production data. And the mine-life extension thesis, backed by the 50,000-metre program and the saddle-zone waste-to-ore argument, is geologically plausible and procedurally on track, yet reserve conversion is a multi-year process that will not conclude before 2027-2028.

None of that is a verdict. It is a clear statement of what has been established versus what remains to be established. The gold price offers margin insulation now while quietly complicating the cost line, and the 80,000-85,000 oz central ore target from 2027 remains a plan rather than a result.
