("AltynGold" or the "Company")

Q3 2025 Production and Operational update

AltynGold (LSE:ALTN), an established precious metals producer operating in Kazakhstan, is pleased to announce its production and operational update for the nine months to 30 September 2025 ("Q3 2025" or the "Period"). Since the start of the year, AltynGold’s flagship Sekisovskoye processing plant has operated at expanded capacity, keeping the Company firmly on track to meet its 2025 annual production target of 50,000 ounces of gold.

Operational and Financial Highlights

AltynGold delivered strong operational and financial performance during the third quarter of 2025, driven by continued growth at its Sekisovskoye mine. Ore mined surged 16% year-over-year (YoY) to 239 kt, bringing the year-to-date (YTD) total to 689 kt – a 28% increase compared to the same period in 2024 (Q3 2024: 540 kt). Ore milled also rose by 53% YoY to 256 kt, respectively, higher than ore mined in the quarter due to inventory being available from previous periods.

Gold production continued its upward trajectory, with YTD output reaching 39,395 ounces, a 41% increase over 2024. For the quarter, gold poured totalled 14,314 ounces, up 36% YoY, supported by steady gold and recovery rates of 2.05 g/t and 84.71% respectively.

Sales performance was equally robust, with 36,515 ounces sold during the period (Q3 2024: 27,358 oz). Combined with a favourable pricing environment averaging $3,363 per ounce, this drove quarterly revenue up by 89% YoY to US$46.8 million, bringing the YTD total to US$116.5 million.

Operational Review

The board is in the early stages of evaluating plans to expand Sekisovskoye's current 1Mt processing capacity to potentially achieve 2Mt-2.5Mt within 24 months. This is subject to ongoing detailed technical, engineering, and financial analysis, with a Board decision expected in H1 2026. The estimated cost of expansion would be approximately US$125m, which the Company’s strong cash generation would support. This near-term expansion is part of AltynGold’s medium-term goal to reach an annual production target of 100 koz.

At Teren-Sai, exploration works continued during the period in line with the agreed work programme, with 9,985 meters actually drilled. While the exploration licence runs until March 2026, the Company remains confident of securing a full mining licence during 2026, paving the way for future development initiatives. Further updates will be provided in due course.
