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.
