AltynGold CEO Aidar Assaubayev commented:

“Sekisovskoye continues to deliver strong results, with production and profitability both showing significant growth in the first half of the year. The combination of higher mined volumes, stable operating costs, and a supportive gold price environment has translated into a 143% increase in operating profit and record EBITDA. Importantly, we achieved this while maintaining our exemplary safety record, with no accidents reported in the period.

With ore stockpiles in place, processing capacity running at enhanced levels, and underground development advancing on schedule, we are well placed to meet our target of 50,000 ounces for the year. The progress on our declines and ore body development underpins the long-term future of the mine, giving us confidence in our ability to continue to grow production towards our medium term goals.

AltynGold is in a robust financial position with compelling cash generation, enabling us to reinvest in mine development and pursue our growth strategy. We remain committed to delivering excellent value for our shareholders while operating safely and responsibly.”

Chairman’s Statement

The first half of 2025 has been one of continued progress for AltynGold. With the expansion of the Sekisovskoye processing plant now complete, the Company is firmly positioned to deliver on its target of 50,000 ounces of production this year, while establishing the platform for our longer-term ambition of 100,000 ounces annually.

Our strengthening financial position reflects both higher output and the supportive gold price environment. Operating profits more than doubled in the half, and adjusted EBITDA rose by 125%. Importantly, cash generation is now accelerating at a pace that will see the Company move into a net cash position in the near term. This transformation provides us with the flexibility to fund growth largely from internal resources, a significant step change from previous years, and one that strengthens our resilience in a volatile global environment.

The quality and notable longevity of AltynGold’s considerable asset base remains a source of real competitive strength. Sekisovskoye has a long reserve life at current production levels, while our exploration work at Teren Sai continues to demonstrate the potential to add further scale and longevity at competitive cash costs to the portfolio. Together, these assets underpin our ambition to become a mid-tier producer of scale, capable of delivering sustainable value over decades. We continue to review organic growth opportunities that could allow us to further expand our high-quality asset portfolio.

We remain committed to pursuing further growth diligently, with a responsible focus on safety, environmental stewardship, and the pursuit of value creation for all stakeholders. The strong gold price environment enhances this opportunity, but it is the strength of our assets and expertise of our employees that give us confidence in our growth strategy.

On behalf of the Board, I would like to thank our employees for their hard work, skill, and commitment, which continue to drive our success. I also extend my gratitude to our shareholders for their trust and support as we execute our strategy.

I would also like to take this opportunity to welcome Maryam Buribayeva to the Board as Chief Financial Officer, which has been announced since the H1 2025 period end. AltynGold has benefited from Maryam’s expertise and deep knowledge of the Company during her tenure as a Non-Executive Director for the past 3 years, and we look forward to her continued leadership as an Executive Director at this exciting time for the Company.

I look forward to providing a further update on our progress later this year.

Chief Executive Officer’s statement

The first half of 2025 marks a decisive turning point for AltynGold. With the successful completion of the Sekisovskoye processing plant upgrade at the beginning of the year, our operations are now firmly positioned to deliver higher output and strong financial performance. This expansion has increased milling capacity by around 50%, underpinning our ability to reach 50,000 ounces of gold production in 2025 and establishing a platform for our longer-term ambition of producing 100,000 ounces annually.

At Sekisovskoye, the mine continues to operate smoothly, with key development milestones achieved during the period. We advanced both transport declines by 322 metres, pushed forward tunnelling into ore body 11, and commissioned significant infrastructure including the new surface ventilation fan unit and the main drainage complex. These projects enhance the long-term resilience and efficiency of our underground operations. The team maintained our strong safety record, with no lost-time incidents recorded in the half, in line with our core commitment to safe operations.

Our primary focus has been the successful implementation of the processing plant at Sekisovskoye and ramping up production to take advantage of the increasing gold prices. Financially, the impact of the processing plant expansion is clear. Revenue rose in the period to US$70m and operating profit increased 143% YoY to US$37m. Adjusted EBITDA more than doubled to US$44m. This reflects higher production volumes and the supportive gold price environment, with an average realised price of over US$3,000 per ounce.

Cash generation is strengthening rapidly, and with net debt expected to fall sharply, we are moving towards a net cash position. This will create financial flexibility to fund the next phase of growth internally.

Our focus on the processing plant has led to a natural change of focus from the accelerated development of Teren Sai that previously envisaged as resources were committed to Sekisovskoye. Nevertheless, we continued drilling programmes at both Sekisovskoye and at our Teren Sai licence area. At Teren Sai, where our exploration licence has been extended until March 2026, we completed nearly 10,000 metres of core drilling alongside mapping and sampling works. This work is progressively de-risking the resource base and increasing our production opportunities, and the next steps are to prepare a resource estimate and determine the most efficient pathway towards production. Together with the 5.05 million ounces of proven and probable reserves across our portfolio, this work supports the scale and longevity of our resource base and provides optionality for growth well beyond current production output.

We are pleased to introduce to our Company disclosures the benchmark cost measure for our operations’ All-In Sustaining Cost (AISC), in line with our commitment to financial transparency and clear disclosure to shareholders. At US$1,357/oz (H1 2024: US$1,284/oz), our AISC clearly demonstrates AltynGold to be a compelling low-cost producer.

Looking forward, our strategy remains focused on two pillars: the continued development of Sekisovskoye and the progression of Teren Sai. The completed plant expansion has lifted our production run-rate to 56,000 ounces achievable from 2026, and we remain committed to scaling to 100,000 ounces annually from our existing resource base.

AltynGold today stands at an inflection point between junior and mid-tier producer. We are delivering strong operational performance, generating meaningful cash flow, and investing in growth responsibly. With our strengthened platform, we are well placed to create sustained value for all stakeholders as we advance towards our long-term vision of becoming a growing, low cost mid-tier gold producer of scale.

Operational overview

Sekisovskoye

With the completion of the final stages of the processing plant upgrade and associated works being completed in January 2025, the mine works have returned to the normal schedules of ongoing maintenance and capital expenditure associated with the ongoing development of the declines. Capital expenditure in relation the final completion of works in relation to the processing plant and capital upgrades amounted to US$7m of the total capex spend of US$11.7m

The principal milestones achieved in the period in relation to the mine development were:

Capital development of the two declines in the period amounted to 322 linear metres.

Drilling and tunnelling works to access the ore in ore body 11 at 0masl.

Backfilling of the voids as the ore is extracted,

Exploratory drilling and blast hole drilling increased to facilitate the higher level of ore to the processing plant.

Construction of the main fan unit building on the surface at elevation +430 masl and installation of Korfmann AL 17-4500 No. 2. Work was also completed on pouring the foundation of the building and the pedestal for the ventilation units.

Completion of the main drainage complex at an elevation of +150 metres above sea level. This included the laying of 1700 linear metres of pipeline, which was also connected to outlets at an elevation of +320 metres above sea level.

Teren Sai

The primary focus of the company has been on the successful implementation of the processing plant at Sekisovskoye, and to ramp up production, to take advantage of the increasing gold prices. This has led to a change of focus from the development of Teren Sai that was previously planned as resources were committed to Sekisovskoye.

To summarise the extension to the exploration licence was granted in April 2024 for a two year period expiring in March 2026. The licence requires exploration to be undertaken in line with a work program agreed with the mining authorities. In the current six month period the following works were undertaken:

Core drilling of 9,720 metres

Topographical mapping works on 31 mines

6,370 samples tested

Testing and sampling has been undertaken in the area 2 identified for development. The results continue to be analysed and collated, to assess if further works are required before moving to the next stage.

The next step will involve the preparation of a resources estimate which may necessitate the involvement of an external advisor and development of a work program to be agreed with the mining authorities.

As the licence expires in March 2026 this may require a renewal of the exploration licence with a view to switching the licence to a production licence on completion of all research. An assessment will be made at this stage as to the how to develop the prospective resource in the most efficient and profitable way.

We will update shareholders as the plans are progressed.

Financial review

* This figure was previously reported as 28,081oz in the H1 2025 production update RNS issued on 18 July 2025.

With the ongoing political and economic uncertainty, caused by the continuing conflicts in the world and the unpredictable economic policies in the USA, the demand and as a consequence the price of gold has been increasing. Major factors pushing the price up have been the demand from central banks diversifying their reserve holdings away from the US Dollar, and investor sentiment on interest rates and inflation. These underlying factors are set to continue with some analysts such as Goldman Sachs seeing prices continuing to move upwards to over US$4,000oz. The average price achieved in H1 2025 was US$3,099, currently the gold price is above US$3,600oz.

With the third line of production becoming fully operational in the period, the gold dore produced increased by 44% to 25,081oz, which was in line with the budgeted plan for the six months. The company is budgeting for a production level of 50,000oz for the full year.

The turnover increased to US$70m an increase of 82% on the higher level of production and increase in the average price of gold achieved of US$3,099oz up from US$2,293. Gross margin increased to 57% from 43%, due principally to the increase in price of gold as the costs are relatively fixed.

The cost of sales increased from US$22m to US$30m the increase of US$8m was due to three principal factors. An increase in depreciation of US$4m as a result of the additional capital expenditure relating to plant construction. Secondly an increase in mineral extraction tax of US$2.9m, this is levied at 7.5% on the ore extracted which increased to 450,000t (2024: 334,000t ) extracted. Thirdly an increase in wage costs in the year of US$0.6m to service the higher level of production.

Sekisovskoye produced 25,081oz of gold dore (H1 2024: 17,413oz), with an increased recovery rate of 84.75%. Gold sold in the period amounted to 22,595oz, with the balance being carried forward into stock to be sold in Q3 2025.

As production continues to grow the cash cost of production is set to reduce (cost of sales excluding depreciation and provisions) and was for the period was US$1,007/oz (H1 2024 US$1,013/oz). The total cash cost was US$1,152/oz as compared to US$1,154/oz in H1 2024.

In terms of administrative costs these increased by US$0.8m to a total of US$3.3m, principally due to a one off adjustment to restate the carrying value of VAT resulting in a provision of US$693,000.

The finance costs represent the interest charges on the bonds at the fixed rates of 11.25% and 9.75% on the two US$10m bonds which amounted to US$1.1m in the period and US$1.8m on the bank loans with interest rates principally at rates between 7%-8%.

Tax levied on the profits relates entirely to the tax charged in Kazakhstan at a rate of 20%, as all the tax losses have now been fully utilised, the tax charge has increased in the current period to US$7.6m

On the back of the strong trading performance adjusted EBITDA rose to US$44m (2024: US$19.6m) in the six months to 30 June 2025.

As of 30 June 2025, the cash balances were US$15m, increasing from the December 2024 balance of US$10.4m.

The net amount of loans repaid in the period was US$11.4m, comprised of additional loans of US$14m and loans repaid of US$25.4m. The loans repaid included the Kazakh Tenge denominated loans which had a higher interest rate of 15.5% per annum. The loans total US$49m at 30 June 2025, the majority of which will be repaid by 2027.

Ore stockpiles have increased from the December 2024 level of US$23.5m to US$37.6m. The increase in the ore stockpiles was planned in order to service the greater running capacity of the processing plant from January 2025.

Basis of preparation

General

AltynGold Plc (the “Company”) is a Company incorporated in England and Wales under the Companies Act 2006, and is tax resident in the United Kingdom. The address of its registered office, and place of business of the Company and its subsidiaries is set out within the Company information at the end of this interim report.

The Company shares are publicly traded on the London Stock Exchange. The interim financial results for the period ended 30 June 2025 are unaudited.

This interim financial information of the Company and its subsidiaries (“the Group”) for the six months ended 30 June 2025 have been prepared, in accordance with the UK-adopted International Accounting Standard 34, 'Interim Financial Reporting' and the Disclosure Guidance and Transparency Rules sourcebook of the United Kingdom’s Financial Conduct Authority, and on a basis consistent with the accounting policies set out in the Group's consolidated annual financial statements for the year ended 31 December 2024. It has not been audited, does not include all of the information required for full annual financial statements, and should be read in conjunction with the Group's consolidated annual financial statements for the year ended 31 December 2024, which has been prepared in accordance with both “international accounting standards in conformity with the requirements of the Companies Act 2006” and “international financial reporting standards as adopted by the United Kingdom”.

These interim financial statements do not comprise statutory accounts within the meaning of section 434 of the Companies Act 2006. Statutory accounts for the year ended 31 December 2024 were approved by the board of directors on 25 April 2025 and delivered to the Registrar of Companies. The report of the auditors on those accounts was not qualified.

The same accounting policies, presentation and method of computation together with critical accounting estimates, assumptions and judgements are followed in this consolidated financial information as were applied in the Group's latest annual financial statements except that in the current financial year, the Group has adopted a number of revised Standards and Interpretations. However, none of these have had a material impact on the Group

Going concern

Turnover, profitability and EBITDA all increased significantly during the period.

At the period end the Group had cash resources of US$15m (31 December 2024: US$10.4m). The Board have reviewed the Group’s cash flow forecasts for the period to December 2026. The forecasts are based on the current approved budgets taking into account any adjustments from current trading. The Directors are of the opinion that the current cash balances and cash generated from future trading will be sufficient for the Group to meet its cash flow requirements.

The Board have considered at the period end possible stress case scenarios that they consider may impact the Group’s operations, financial position and forecasts, such as increasing unbudgeted production price increases and possible falls in gold prices. From the analysis undertaken the Board have concluded that the Group will be able to continue to trade based on its existing resources.

The stress tests included a drop in the gold price of 10% from the current gold price and budgeted production prices increasing by 10%, in both scenarios and combination of both together it was concluded that the Group had sufficient cash reserves to continue to operate.

The predicted cash flow from operations is forecast to be sufficient to repay the loans as due and repayable. Additional finance will be sought if required from the principal banker or raised on the AIX if necessary.

The Board therefore considers it appropriate to adopt the going concern basis of accounting in preparing these financial statements.

Segmental information and analysis of revenue

Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision maker. The chief operating decision maker, who is responsible for allocating resources and assessing performance of the operating segments and making strategic decision, has been identified as the Board of Directors.

The Board of Directors consider there to be two operating segments, the exploration and development of mineral resources at Sekisovskoye and at Teren-Sai, both based in one geographical segment, being Kazakhstan.

All sales were made in Kazakhstan from the mine at Sekisovskoye. In relation to Teren-Sai as there is discrete financial information available and the assets account for greater than 10% of the combined total assets of all segments it is considered as a separate operating segment.

Teren Sai is currently an exploration asset and expenditure in relation to the asset are capitalised, the carrying value of the asset are shown in note 5.

Total revenues of US$70,010,000 (2024: US$38,397,000) relate to sales of gold and silver which arose from sales to one customer based in Kazakhstan.

Other earnings amounted to US$150,000 (2024: US$1,146,000) which related to lease and rental income.

Earnings per ordinary share

Basic and fully diluted earnings per share is calculated by dividing the profit attributable to ordinary shareholders by the weighted average number of ordinary shares outstanding during the period. The weighted average number of ordinary shares and retained profit for the financial period for calculating the basic loss per share for the period are as follows:

Alternative performance measures

The Directors have presented the alternative performance measures adjusted EBITDA , operating cash cost and total cash cost as they monitor these performance measures at a consolidated level and the Directors believe it is relevant in measuring the Group’s performance.

A reconciliation of the alternative performance measures is shown below.

Adjusted EBITDA, operating cash cost and total cash cost are not defined performance measures in IFRS. The Group’s definition of adjusted EBITDA may not be comparable with similar titled performance measures as disclosed by other entities.

The total capital expenditure in the period was US$11.7m (2024: US$12.2m), of this amount US$7.1m (2024: US$9.9m) was deemed to be non-sustaining capital expenditure as it related to the development of the increased capacity of the processing plant.

Intangible assets

The intangible assets relate to the historic geological information pertaining to the Teren-Sai ore fields. The ore fields are located in close proximity to the current underground mining operations of Sekisovskoye.

Property, plant and equipment

The amount recoverable in relation to Value Added Tax is expected to be recovered by offset against VAT payable in future periods.

The advances to suppliers relate to payments made to acquire mining equipment.

The prepayments principally relate to advances to suppliers for parts and consumables.

Trade and other payables

*This amount excludes US$243,000 capitalised as part of exploration costs see note 5.
