The full interim statements together with commentary can be accessed on the Company’s website using the following LINK . Colm Howlin, CFO, Commented “The first quarter of 2026 marked a strong start to the year, building on the positive momentum in 2025. Gold production for the quarter totalled 12,043 ounces, representing a 20% increase on Q1-2025, driven by higher feed grades at both Palito and Coringa, as well as the commencement of production from the Meio zone at the Coringa Mine.

Cash cost and AISC are incrementally higher than Q4-2025, largely driven by the ramp up at Coringa. With the Meio zone now at commercial production, costs associated with mining the Meio zone are now included in cash cost and AISC. The strong operational performance delivered cash generation of $15.2 million in the quarter, increasing the Group’s cash position to $64.4 million on 31 March 2026, up from $49.2 million at 31 December 2025.

The average realised gold price for the quarter was $4,926 per ounce, compared to $2,908 per ounce for the first quarter of 2025. The exploration results from 2025 and the first quarter of 2026 have consistently demonstrated strong mineralisation continuity and highlight the significant upside potential across our licence areas. We look forward to providing further exploration updates in the coming weeks.” Overview of the financial results Reported revenues and costs reflect the ounces sold in each period and as a result total revenues and costs for the three-month period are higher than the corresponding period in 2025.

In Q1-2026, the Group reported revenue and operating costs related to the sale of 10,323 ounces in the period (12,043 ounces produced). This compares to sales reported of 9,699 ounces in Q1-2025 (10,013 ounces produced). The Company continued to benefit from a strong gold price throughout the first quarter of 2026, with the most material uplift occurring in March, with the USD gold price rising to $5,095 and averaging $4,926 for the quarter, compared to a current spot price of approximately $4,571 per ounce.

This contributed to a Q1 average gold price in Brazilian Real of BRL25,881. In Q1-2026, the average USD gold price increased by 69% in comparison to Q1-2025 ($4,926 in Q1-2026 vs $2,908 in Q1-2025). BRL strengthened during Q1-2026, with the USD:BRL rate moving from 5.5 at 31 December 2025 to 5.25 at 31 March 2026.

This strengthening limited the extent to which the stronger USD gold price translated into local currency margins. The Group delivered a strong start to 2026 with an 20% increase in production year-on-year, driven by significant grade improvements at Coringa (+39%). The classification plant at Coringa contributed meaningfully to the grade uplift, while development at the Meio and Galena veins continued during the first quarter of 2026.

Cash balances at the end of March 2026 were $64.4 million, in comparison to the cash balances at the end of December 2025 of $49.2 million. On 16 January 2026 the Company fully repaid its $5.3 million unsecured loan arrangement with Santander Bank in Brazil which carried an interest coupon of 6.16 per cent. The company did not engage in any new loans during the year of 2026.

Statements of Changes in Shareholders’ Equity For the three-month period ended 31 March 2026 (1)     (1) Other reserves comprise a merger reserve of US$361,461 and a taxation reserve of US$23,691,102 (31 December 2025: merger reserve of US$361,461 and a taxation reserve of US$23,381,928). Condensed Consolidated Cash Flow Statement For the three-month period ended 31 March 2026 Notes Basis of preparation These interim condensed consolidated financial statements are for the three-month period ended 31 March 2026.

Comparative information has been provided for the unaudited three-month period ended 31 March 2025 and, where applicable, the audited twelve-month period from 1 January 2025 to 31 December 2025. These condensed consolidated financial statements do not include all the disclosures that would otherwise be required in a complete set of financial statements and should be read in conjunction with the 2025 annual report. The condensed consolidated financial statements for the periods have been prepared in accordance with International Accounting Standard 34 “Interim Financial Reporting” and the accounting policies are consistent with those of the annual financial statements for the year ended 31 December 2025 and those envisaged for the financial statements for the year ending 31 December 2026.

Accounting standards, amendments and interpretations effective in 2026 The Group has not adopted any standards or amendments in advance of their effective date. The following new amendment has been issued by the IASB and is effective for annual periods beginning on or after 1 January 2026: No other standards or amendments are expected to be effective in 2026. Certain new accounting standards and interpretations have been published that are not mandatory for the current period and have not been early adopted.

These standards are not expected to have a material impact on the Company’s current or future reporting periods. These financial statements do not constitute statutory accounts as defined in Section 434 of the Companies Act 2006. (i)       Going concern At 31 March 2026 the Group held cash of US$64.4 million which represents an increase of US$15.2 million compared to 31 December 2025. On 16 January 2026, the Group repaid Banco Santander in Brazil US$5.3 million relating to the short-term working capital loan plus interest which the Group had previously entered on 22 January 2025.

As a result, at the time of writing, the Group is debt free. Management prepares, for Board review, regular updates of its operational plans and cash flow forecasts based on their best judgement of the expected operational performance of the Group and using economic assumptions that the Directors consider are reasonable in the current global economic climate. The current plans assume that during 2026 the Group will continue gold production from its Palito Complex operation as well as increase production from the Coringa mine and will be able to increase gold production to exceed the levels of 2025.

The Directors will limit the Group’s discretionary expenditures, when necessary, to manage the Group’s liquidity. The Directors acknowledge that the Group remains subject to operational and economic risks and any unplanned interruption or reduction in gold production or unforeseen changes in economic assumptions may adversely affect the level of free cash flow that the Group can generate on a monthly basis. The Directors have a reasonable expectation that, after taking into account reasonably possible changes in trading performance, and the current macroeconomic situation, the Group has adequate resources to continue in operational existence for the foreseeable future.

Thus, they continue to adopt the going concern basis of accounting in preparing the Financial Statements. 2. Finance expense and income 3. Taxation The Group has recognised a deferred tax asset to the extent that the Group has reasonable certainty as to the level and timing of future profits that might be generated and against which the asset may be recovered.

The deferred tax liability arising on unrealised exchange gains has been eliminated in the three-month period to 31 March 2026 reflecting the stronger Brazilian Real exchange rate at the end of the period and resulting in deferred tax income of US$31,310 (three months to 31 March 2025 – income of US$466,264). The Group has also incurred a tax charge in Brazil for the three-month period of US$6,476,140 (three months to 31 March 2025 tax charge - US$2,476,015). 4. Earnings per Share (1) At 31 March 2026 there were 2,728,049 conditional share awards in issue (31 March 2025 – 3,357,649).

These are subject to performance conditions which may or not be fulfilled in full or in part. These CSAs have not been included in the calculation of the diluted earnings per share. 5. Post balance sheet events On 12 May 2026, the Board of Directors awarded in aggregate 458,114 Conditional Share Awards (“CSA’s”) to employees (including directors) of the Company. .
