Production Report for Q3 and the 9 months ended 30 September 2025

 

Eduardo Landin, Chief Executive Officer said:

"We remain on track to achieve our revised 2025 production targets. At Mara Rosa, the optimisation process is progressing well, with improvements to the tailings filter processes and mining activities meeting expectations and setting a solid foundation for 2026. We have also recently welcomed Cassio Diedrich as our new COO and made a number of other appointments to strengthen our local leadership team. We anticipate cash flow to increase in Q4 as output from Mara Rosa gradually ramps up, supported by strong metal prices and a robust period expected at the Inmaculada and San Jose mines."

Overview

In Q3 2025, Hochschild Mining PLC (HOC.LN) (OTCMKTS: $HCHDF) ("Hochschild" or "the Company") delivered attributable production of 70,308 gold equivalent ounces or 5.8 million silver equivalent ounces. The reduction versus the second quarter of 2025 was almost entirely due to the previously announced ramp-up of Mara Rosa after the four-week suspension of the processing and filtering plants, as well as temporary lower grades from mine sequencing at Inmaculada. Overall year-to-date attributable production is 231,905 gold equivalent ounces or 19.2 million silver equivalent ounces.

 

The Company reaffirms that it remains on track to meet its revised 2025 guidance, including an overall attributable production target of 291,000 to 319,000 gold equivalent ounces and an all-in sustaining cost range of $1,980 to $2,080 per gold equivalent ounce. This progress is being achieved despite the impact of higher metal prices on cut-off grades, which is expected to create opportunities over the coming quarters to process lower-grade material with high profit margins at all mines.

Third quarter production at Inmaculada was 33,856 ounces of gold and 1.3 million ounces of silver which amounts to a gold equivalent output of 49,892 ounces. Although tonnage during the period was higher than expected, September's production was impacted by lower grades resulting from mine sequencing adjustments made to address one-off geomechanical challenges that temporarily restricted access to a higher-grade zone. Year-to-date, Inmaculada's output is 156,088 gold equivalent ounces (Q3 YTD 2024: 167,664 gold equivalent ounces), with the mine in line to deliver its full year guidance of between 199,000 and 209,000 gold equivalent ounces.

The San Jose mine delivered a solid performance with production slightly above the previous quarter although grades were a little lower than expected from mining the border zones. Output in the period was 1.0 million ounces of silver and 19,681 ounces of gold which represents 2.6 million silver equivalent ounces. This amounts to a nine-month total of 7.0 million silver equivalent ounces (Q3 2024 YTD: 7.1 million ounces).

As reported in August, production resumed at Mara Rosa in July using two of the four tailings filters, with the remaining two subsequently coming online in mid-September and mid-October respectively. Operational performance continues to show steady improvement, with mining movement rising from 44,000 tonnes per day in August to 66,000 tonnes per day in September. The October run-rate has been exceeding 70,000 tonnes per day and includes a record daily peak of approximately 89,000 tonnes per day. This consistent progress demonstrates greater fleet efficiency and improved haulage conditions.

 

The Company has also largely completed a full reorganisation of the Brazil operations, including the previously announced appointment of the new Brazil General Manager, Ediney Drummond as well as a new Operations Manager, alongside the implementation of a revamped management structure.

 

Gold production for Q3 2025 totalled 4,474 ounces (Q3 2024: 23,752 ounces), with the year-on-year decrease due to the implementation of the ongoing Mara Rosa turnaround plan which included a four-week suspension of the processing plant.

 

Average realisable prices and sales

Average realisable precious metal prices in Q3 2025 (which are reported before the deduction of commercial discounts) were $3,195/ounce for gold and $42.4/ounce for silver (Q3 2024: $2,422/ounce for gold and $29.8/ounce for silver). For the first nine months of 2025, average realisable precious metal prices were $2,937/ounce for gold and $36.5/ounce for silver (Q3 YTD 2024: $2,296/ounce for gold and $28.0/ounce for silver).

 

Brownfield exploration

Inmaculada

During Q3, a total of 9,139m of resource drilling was completed in the Angela, Martha Techo, Dayana, Melisa NE, and Lady veins. Drilling also intersected the Angela Sur, Mirella, Liz, Lady Sur, Ann, Gera, and Ramal Y veins yielding economic results that will add new resources.

Financial position

Total cash was approximately $92 million as at 30 September 2025. Net debt increased from $202 million to $246 million in Q3, primarily due to a temporary accumulation of end-product inventory and receivables in Argentina to protect the balance sheet from a potential devaluation after the upcoming mid-term elections ($40 million), the repurchase of the Monte do Carmo streaming agreement from Sprott ($13 million) and the payment of the interim dividend to shareholders ($5 million). Also contributing were the significantly lower production rate at Mara Rosa during the quarter and the expenditure related to the operation's ongoing turnaround plan.

 

ESG update

ESG performance continued to strengthen in Q3, with an 87% improvement in key indicators compared to 2024, following a 56% increase between 2023 and 2024. Record results were achieved in local workforce representation (65.8%), domestic waste landfilled (0.79 kg/person/day), and potable water consumption (120 litres/person/day), reflecting continued progress in integrating sustainable practices across our operations.

 

Environmental performance remained strong, achieving an ECO Score of 5.61 out of 6, surpassing the "excellent" threshold of 5.50. Safety performance was also robust, with a Lost Time Injury Frequency Rate (LTIFR) of 1.19-below the target of 1.40-and zero fatalities or work-related illnesses reported.

 

External recognition continued to improve, with Sustainalytics upgrading the Company's ESG Risk Rating from 28.4 to 26.8, outperforming the precious metals sector average of 30.2. This marks the second upgrade in 2025, following MSCI's move from BB to BBB, further reinforcing the Company's standing as a responsible operator.

 

Progress toward climate commitments also advanced. The Mara Rosa solar power initiative is now fully operational and supplying 45MWh to the mine and meeting its lifetime energy requirements. At San Jose, the final transition to renewable energy was completed, replacing the remaining 1.6MWh of fossil fuel contracts with wind power. From 1 November 2025, the mine will operate entirely on renewable energy.
