Operated by PT Bumi Suksesindo (BSI), the Tujuh Bukit Gold Mine is one of the largest gold mines in Indonesia, utilizing an efficient heap leaching method. This project is a key asset of PT Merdeka Copper Gold Tbk and plays a vital role in the company’s long-term business strategy.
BSI operates Tujuh Bukit Gold Mine under a Mining Business License for Production Operations, granted in 2012, located in Sumberagung Village, Pesanggaran Subdistrict, Banyuwangi Regency, East Java Province. Mining activities began in 2016, with first gold pour in early 2017. In recognition of its high-quality mineral resources, the site was designated a National Vital Object in 2016, acknowledging its status as a strategic national asset.
Merdeka continues to optimize mining operations to extend the mine’s economic life through 2029. This includes effectively reducing operating costs, improving productivity, and expanding the heap leach area. Exploration in 2024 identified new mineralized zones with the potential to increase gold reserves.
Tujuh Bukit Gold Mine is committed to sustainable mining by mitigating, minimizing, and restoring environmental impacts from its operations. Initiatives include water conservation, a closed-loop water recycling system, and progressive land reclamation and reforestation within and beyond the mine site. The company also regularly monitors biodiversity in collaboration with local communities and conducts air and water quality testing.
In addition to being the largest taxpayer in Banyuwangi, BSI contributes to community welfare in surrounding areas through job creation, business opportunities for local entrepreneurs, and community development and empowerment programs. The mine also provides career opportunities for women as mining equipment operators.
BSI has received numerous awards for its achievements in sustainable mining practices and community development. These include the 2024 Tamasya Award, a government recognition for outstanding implementation of Community Development and Empowerment (PPM) programs, as well as honors for excellence in environmental management, safety standards, and corporate social responsibility. In 2025, BSI received a Blue PROPER rating from the Ministry of Environment for compliance with environmental regulations during mid-2023 to mid-2024.
