Solidcore Resources plc (“Solidcore” or the “Company”) announces production results for the second quarter ended 30 June 2026.

“In Q2, our operations delivered healthy results, however cash flow generation was negatively affected by the temporary disruptions in shipment of the dore bars from third-party POX. Shipments returned to their normal pace in July, and we are continuing to target the release of the accumulated inventories and our original production plan of 540 Koz for the full year”, said Vitaly Nesis, CEO of Solidcore Resources plc.

HIGHLIGHTS

• No fatal accidents among the Company’s employees and contractors occurred in Q2 2026. One lost-time injury was recorded in April, the employee received the necessary medical treatment, and there is no threat to their life or long-term health.
• Gold equivalent (GE) production increased by 56% year-on-year (y-o-y) to 86 Koz in Q2 2026 and by 71% to 210 Koz in H1 2026, driven by third-party concentrate processing recovery.
• Mine level metal output was largely on par with 2025 level at 145 GE Koz in Q2 and 267 GE Koz in H1 2026, demonstrating operational stability at the Company’s assets.
• GE sales for the reporting quarter amounted to 82 Koz and were 24% higher y-o-y, while half-yearly number grew by 97% y-o-y to 205 Koz, on the back of the increase in production.
• Following changes to the Russian gold export regulations introduced by the May Presidential Decree, doré shipments were temporarily delayed from late May until early July. This resulted in a temporary build-up of metal inventories at Amursk POX, with shipments to Kazakhstan successfully resuming at the beginning of July.
• Revenue for three and six months increased by 71% and 199% y-o-y to US$ 369 million and US$ 972 million respectively driven by strong gold prices, healthy production results and higher sales.
• Net cash decreased by 7% to US$ 648 million compared with US$ 699 million as at the end of Q1 2026.
• Ertis POX project development is progressing in line with the schedule. The project design documentation has received a positive state construction expertise approval, and the construction-phase environmental permit has been issued.
• In July, the Company signed a US$ 600 million financing package for the construction of the Ertis POX project, comprising a US$ 300 million loan from the European Bank for Reconstruction and Development and a US$ 300 million syndicated facility arranged by ING, Société Générale and Abu Dhabi Commercial Bank.
• Syrymbet is approaching construction decision in September 2026. Feasibility Study is being finalised, engineering surveys are mostly complete, with site preparation and vendor engagement is underway.
• The Company is expected to publish the half-year financial results on 8 September 2026.

KYZYL

Q2 and H1 2026 gold production at Kyzyl increased by 152% and 159% y-o-y to 41 Koz and 122 Koz, respectively. The growth is primarily attributable to the recovery of toll-processing operations at Amursk POX after disruptions in 2025 and the commencement of concentrate toll-processing at the Kazakhmys smelter. In H1, dore production at Kazakhmys and POX contributed 66 Koz and 56 Koz to total production, respectively.

In H1 2026, gold in concentrate volumes decreased on the back of the planned depletion of open-pit reserves at the Eastern part of the pit, which had higher recovery rates.

Stripping volumes decreased due to the gradual scaling-down of open-pit mining operations. The Company plans to begin underground ore mining in 2030.

Ore mined in Q2 decreased in line with the mine plan. The shortfall will be offset in H2 and the full-year mining volume is expected to remain at the 2025 level.

VARVARA

At Varvara, quarterly production increased by 16% y-o-y to 45 Koz, mainly due to higher grades at the leaching circuit, as higher-grade ore from the deeper levels of the southern part of the Komar pit has been fed into the circuit since Q4 2025.

The flotation circuit recorded a decline in production, reflecting lower processing volumes attributable to the depletion of Varvara's high-copper-grade reserves within the current pit. The plant processed mainly third-party material with higher grades, which increased the average grade at the circuit.

DEVELOPMENT PROJECTS

• At Ertis POX, several key milestones have been achieved. The Company secured US$ 600 million funding from a syndicate of international banks, shipment of main process equipment has started, and the positive conclusion of the comprehensive state construction expertise for the main construction phase was obtained in June 2026. The international Environmental and Social Impact Assessment (ESIA) has been completed in May, including public consultation on the ESIA Report.
• The Syrymbet project continues to advance toward the start of the full-scale construction: the feasibility study is in its final stage, marketing of the key equipment is progressing as planned and the Board’s investment decision is scheduled in September 2026. Engineering surveys are 95% complete, while site preparation is underway to enable the commencement of foundation works.

SUSTAINABILITY, HEALTH AND SAFETY

During the reporting period, one lost time injury recorded among the Company’s employees. Injury was classified as moderate as the result of a fall from mining machinery during maintenance. Following the incident, injured employee has received necessary medical attention. The Company conducted additional safety procedures to reduce relevant risks. No fatalities were recorded among employees or contractors, and no lost-time injuries were recorded among contractors. Accordingly, the total number of days lost due to work-related injuries (DIS) in H1 2026 amounted to 64 days, and the Lost Time Injury Frequency Rate (LTIFR) was 0.06 (compared to zero in H1 2025). Safety remains the top priority for Solidcore as we aim to maintain zero fatalities across our operations and among on-site contractors. The Company is committed to implementing initiatives that further enhance health and safety conditions.

The Company is actively working to de-risk its energy supply while reducing costs and greenhouse gas (GHG) emissions. During Q2, construction of the 40 MW gas-piston power plant at Varvara, which complements the previously commissioned 23 MW solar power plant, progressed in line with schedule. All major equipment has been delivered, fabrication of the structural steel frameworks for the planned buildings has been completed, and construction works are ongoing. Commissioning of the plant is scheduled for the end of 2026. At Kyzyl, active engineering and pre-construction works are also underway for the 17 MW solar power plant, which is expected to be commissioned by the end of 2027.
