Production Targets Exceeded, Record Revenue Achieved

London, 22 January 2026 - AltynGold (LSE: ALTN), an established precious metals producer operating in Kazakhstan, is pleased to announce its production and operational update for the three months to 31 December 2025 ("Q4 2025" or the "Period") and the twelve months to 31 December 2025 ("Full Year").

The Company delivered a highly creditable operational performance during the Period, producing 53.8Koz ounces of gold, exceeding guidance. This performance, combined with a favourable gold price environment, resulted in record-breaking annual revenue of US$175.25 million, the highest in the Company's history. These achievements underscore AltynGold's ability to deliver its growth strategy on time and on budget, providing a strong foundation for future strategic growth initiatives and the Company's evolution towards mid-tier production status.

For 2026, the Company is targeting gold production of 52,000-55,000 ounces, reflecting continued optimisation of operations following the successful expansion of its processing capacity.

Operational and Financial highlights

During the final quarter, the Company maintained its momentum and continued to scale production across its operations, driven by the expanded processing capacity. Key production and operational highlights include:

• Ore mined in Q4 2025 increased 13% year-over-year (YoY) to 237Kt, with Full Year figure reaching 926Kt, a 24% YoY increase compared to 750Kt in 2024;

AltynGold CEO Aidar Assaubayev commented:

"We are extremely pleased to have delivered another year of strong operational performance, successfully achieving our full-year production target of 50,000 ounces. The fourth quarter marked a solid finish to the year, reflecting the benefits of expanded processing capacity and our team's continued focus on operational discipline.

Looking ahead, management is highly focused on advancing the evaluation, to take a Board decision before Summer 2026, on further expansion opportunities at Sekisovskoye, including detailed work on the technical scope and funding framework required to support future growth. This disciplined approach ensures that any expansion is underpinned by robust analysis and aligned with long-term value creation.

Supported by a favorable gold price environment and strong cash generation, we enter 2026 with positive operational and financial momentum. With forecast production guidance of 52,000 to 55,000 ounces, we remain confident in our ability to continue delivering value while progressing to the next phase of the Company’s development.

Expanded Tailings Storage

During the year, the Company expanded its tailings storage capacity to accommodate increased production volumes, with the area of Tailings Dam 4 expanded by approximately 1.5 million square metres. The enhanced storage capacity is expected to be sufficient to support operations through to March 2027.

During 2026 the Company will be commencing work on expanding Tailings Dams 2 and 3 this will provide additional tailings storage capacity until 2029.

Strategic Growth and Expansion Plans

Sekisovskoye Processing Capacity Expansion

Following the successful upgrade completed in December 2024, the Sekisovskoye processing plant approached its maximum capacity of 1Mtpa. AltynGold continues to progress with its evaluation of production plans to further expand processing capacity to potentially achieve 2-2.5Mtpa within 24 months.

A detailed technical, engineering and financial review is currently underway to assess the scope, timing and capital requirements. Subject to the outcome of this analysis, a Board decision is expected in H1 2026.

Teren-Sai Mining Licence

The Company is finalising the application for a full mining licence, with a view to securing approval in 2026, which will be an important step towards unlocking the longer-term development potential of Teren-Sai. Further updates will be provided as the licensing process advances.

2026 Production Guidance

Building on our proven track record of consistently meeting production targets, AltynGold's focus for 2026 will be on maximising operational efficiency at the Sekisovskoye site. Whilst the Company continues to assess operational efficiencies, we anticipate grade recoveries at Sekisovskoye remaining broadly in line during 2026. The Company plans to maintain a processing run rate of approximately 83Kt per month and is targeting gold production of 52Koz-55Koz for the year.

Safety, sustainability and leadership

The Company recorded its fifth consecutive zero-incident year, reflecting a strong and well-embedded safety culture across the business. Safety remains a core operational priority, supported by ongoing employee and management engagement, regular training, and robust operational oversight.

During the year, the collaboration with Hokkaido University continued under the Smart Mining+ research programme. A second visit by university representatives to the Sekisovskoye mine took place in September 2025. Analysis of samples and data collected is currently underway. Once the results are finalised, the programme will continue through the phased installation of underground equipment and wireless technologies. The project is expected to run through to 2030.

Following the appointment of Maryam Buribayeva as Chief Financial Officer, Andrew Terry has assumed her former position as an Audit Committee member. Andrew brings extensive experience in finance, taxation and capital markets, further strengthening the Company's governance framework.
