Full-year production guidance of 50,000 to 55,000 gold ounces remains unchanged. The company held $43 million in cash and carried no debt at quarter-end
90-Second Brief
In recent days, heliostar Metals reported a record 14,803 gold ounces and 79,710 silver ounces produced in Q2 2026 across its two Mexican heap leach mines, La Colorada and San Agustin. The company posted a consolidated cash cost of $1,654 per ounce sold and a corporate all-in sustaining cost of $2,287 per ounce, both unaudited figures as reported by the company. Full-year production guidance of 50,000 to 55,000 gold ounces remains unchanged. The company held $43 million in cash and carried no debt at quarter-end.
What This Changes for Mining Operations Directors
The operational signal worth extracting here is not the headline ounces—it is how La Colorada managed its production method transition without a visible cost blowout. The mine pivoted away from loading, crushing, and stacking on stockpile material in late Q1 and moved into vertical injection leaching across the west portion of the leach pad. That is a significant operational change mid-year. Despite it, La Colorada’s Q2 cash cost came in at $1,531 per ounce sold, below the consolidated average, with AISC at $1,641 per ounce. The mechanism behind that was sequenced infrastructure investment: a second injection leaching unit was brought online during Q2, and a well field was drilled across the leach pad to support injection through the remainder of the year and into 2027.
For operations directors managing aging heap leach assets or transitioning between production sources, the relevant question is sequencing. Heliostar’s approach—pre-drilling the well field, commissioning the second injection unit, and overlapping residual leaching with injection leaching during the transition—appears to have prevented the gap in recoverable ounces that typically hits costs when stockpile material is exhausted before the next production source is online. The company characterises its re-leaching performance as exceeding expectations, though these are management statements from an unaudited release and have not been independently verified.
San Agustin tells a different story at the cost line. Cash cost ran at $1,814 per ounce and AISC at $2,228 per ounce in Q2, with the elevated sustaining cost driven by a planned expansion of the 4B Leach Pad. That construction investment represents a straightforward trade-off: accept higher near-term AISC to extend available leach capacity. More operationally useful is the grade control outcome at San Agustin—ore tonnes from the Corner area reserve consistently reconciled above the reserve model during Q2. That positive variance directly affected cash flow; the mine is described as a major cash flow contributor in Q2, and the reconciliation result suggests the grade control program is running ahead of plan rather than compensating for a shortfall.
The Veta Madre restart at La Colorada introduces a different operational sequence for 2027 and 2028. Contractor mobilization for capitalized waste stripping had commenced at quarter-end, with stripping set to begin in August 2026. Ore from Veta Madre is not expected in production until late Q2 2027. That gap—waste stripping now, ore production in twelve months—means La Colorada’s near-term output rests almost entirely on injection leaching performance through the rest of 2026 and the early part of 2027. If injection yields disappoint relative to plan, the mine has limited short-term alternatives before Veta Madre ore becomes accessible. That is the principal operational exposure in the current production architecture.
Separately, the Goldstrike acquisition in Utah—closed in Q2 at a reported cost that included a $10 million cash payment to Liberty Gold—adds geographic and commodity diversification but contributes no near-term production. The project’s indicated resource of 975,000 ounces at 0.46 grams per tonne gold in a Carlin-style system is early-stage, with a Pre-Feasibility Study as the next development milestone. For operations directors, this is a pipeline signal rather than an operating asset signal: it does not affect current cost or production profiles, but it indicates how the company intends to deploy cash generated from its two producing mines.
What to Watch Next
The most operationally material forward signal is injection leach yield performance at La Colorada through Q3 and Q4 2026. If Q3 results show injection volumes and gold recoveries tracking to plan, that validates the transition methodology and the infrastructure investment thesis. If yields fall below expectation, costs will move toward the upper end of guidance—or beyond—before Veta Madre ore is available to compensate.
The second signal is waste stripping progress at Veta Madre. The timeline from stripping commencement in August 2026 to first ore in late Q2 2027 leaves little slack. Any geotechnical event, contractor performance issue, or permitting friction could compress that window and create a production gap in 2027. No geotechnical characterization of the Veta Madre pit was disclosed in Q2 reporting, so slope and ground conditions at the operating face remain an unquantified variable.
At San Agustin, the 15,000 to 18,000 metre drill program targeting oxide resources at pit margins is the mine life indicator to track. The company reports that early results match the grade and thickness of material currently being mined profitably. If resource modelling confirms that and permitting supports pit extension, San Agustin’s contribution beyond the current Corner reserve extends meaningfully. If modelling fails to confirm commercial continuity, the mine’s productive window contracts toward 2027.
One element that remains unclear from the Q2 release is the breakdown of AISC components driving the consolidated figure above the full-year guidance range. Management attributes partial responsibility to elevated diesel prices and profit sharing tied to strong 2025 performance. How much of that cost pressure persists through H2, and whether diesel hedging or contract structures are in place, is not disclosed. For any operations director using this as a cost benchmark reference, that gap in disclosure limits direct comparability.
