AltynGold plc engages in the exploration, development, and production of gold and silver resources in the Republic of Kazakhstan. The company operates its flagship 100% owned Sekisovskoye gold and silver mine located in northeast Kazakhstan near the village of Sekisovka, approximately 40 kilometers from Ust-Kamenogorsk; it also advances the adjacent Teren-Sai exploration and development project in East Kazakhstan, which features open-pit potential with indicated grades of 1.8 g/t gold and plans for underground operations. AltynGold produces gold doré bars from high-grade ore processing via its expanded facility targeting 800,000 to 1 million tonnes per annum capacity; underground mining employs equipment including Cat AD30 trucks, R1300 LHDs, and Epiroc Simba K102 drilling rigs; and exploration activities focus on reserve delineation and mine life extension. Founded in 1997 and headquartered in London, United Kingdom, at 28 Eccleston Square, AltynGold plc is a subsidiary of AGold Mining Group Plc and lists on the London Stock Exchange under the ticker ALTN.L. In recent developments, the company completed its processing plant expansion program on budget in 2024 to support higher production volumes, achieving nearly 50% revenue growth driven by increased output, stronger gold grades, and favorable prices; it targets over 50,000 ounces of annual gold production in 2025, representing a 60% increase over two years; secured a $40 million credit line from Kazakh Bank JSC Bank Center Credit in 2022 for underground fleet additions and growth toward 1 million tonnes per annum; signed a collaborative research agreement with Hokkaido University of Japan in June 2025 as part of ESG initiatives; and actively assesses domestic acquisition opportunities to expand its multi-asset portfolio.
