Two Turangga Resources Subsidiaries Achieve Green Rating in PROPER 2024-2025 from the Ministry of Forestry and Ministry of Environment

Jakarta (08/04/2026) – Turangga Resources, through two of its subsidiaries, PT Asmin Bara Bronang (ABB) and PT Suprabari Mapanindo Mineral (SMM), is honored to announce the achievement of Green Rating in the Program Penilaian Peringkat Kinerja Perusahaan dalam Pengelolaan Lingkungan Hidup (PROPER) for the 2024-2025 period issued by the Ministry of Environment/Environmental Control Agency of the Republic of Indonesia (07/04/2026).

PROPER is a national-level evaluation instrument that assesses company performance in environmental management and compliance with environmental laws and regulations. The Green Rating achieved by ABB and SMM demonstrates that both companies have implemented environmental management efforts that exceed the requirements stipulated in regulations (beyond compliance) through good environmental management systems and efficient resource utilization.

This achievement is tangible proof of Turangga Resources' commitment to integrating environmental sustainability principles in every aspect of mining operations. Both companies have consistently implemented best practices in environmental management, including water, air, and waste management, as well as biodiversity conservation programs and post-mining land rehabilitation.

"We are proud of achieving the Green PROPER Rating. This is recognition of the dedication and hard work of the entire team in conducting mining operations that are environmentally responsible and sustainable," said Arianto Sasono, President Director of SMM.

"The PROPER award serves as a benchmark for ESG compliance. With the green rating, the government acknowledges that ABB is at the beyond compliance level, as it was also in 2023 and 2025," said Eko Susanto, Director of ABB.

"This also strengthens our commitment that business growth must go hand in hand with environmental preservation and community welfare," added BJ Basuki, Director of ABB.

ABB and SMM have implemented various flagship programs in environmental management, including:

• Water and Energy Management: Water Treatment System at CPP-Washing Plant Asmin Bara Bronang and Solar PV Optimization across various operational areas
• Solid and Liquid Waste Management: Organic Waste Processing through Composting, Biopori, Biodigester, Eco-enzyme, Maggot (BSF)
• Biodiversity Conservation: Asmin Tropical Rain Forest (Arboretum)
• Land Rehabilitation: Reclamation and revegetation of post-mining land with local vegetation
• Community Empowerment: Corporate Social Responsibility (CSR) programs integrated with environmental management and surrounding community empowerment

PROPER assessment is conducted through comprehensive evaluation of various aspects, including compliance with environmental regulations, effectiveness of environmental management systems, energy and resource efficiency, and company relations with communities. PROPER ratings are divided into five categories: Gold (best), Green (very good), Blue (good), Red (poor), and Black (very poor).

The Green Rating achieved by both Turangga Resources subsidiaries places Turangga Resources in the "very good" category alongside other companies that have demonstrated extraordinary commitment to sustainable environmental management.

Moving forward, Turangga Resources is committed to continuously improving environmental performance across all operational areas and targeting higher achievements in future PROPER assessments. Sustainable efforts will continue through environmentally friendly technology innovation, human resource capacity building, and collaboration with various stakeholders to create broader positive impacts for the environment and communities.
