formal commencement of mining operations.

The start of production marks the implementation of the IDR 12 trillion (equivalent to over USD 755

surrounding our operations.”

359,330,000 bank cubic meters (bcm) of overburden and 60 million tons of coal. Located in Central
Kalimantan, the project reflects the long-term trust in BUMA’s proven ability to deliver large-scale,
integrated mining services solutions.

Novraym Vianus Keriahenta Meliala, ST, Director of SINI, commented, "We are optimistic about
achieving the coal production targets of SINI's subsidiaries through our collaboration with BUMA, and
while continuing to strengthen our subsidiaries' commitment to Good Mining Practices, and
highlighting PKP's role as one of SINI's subsidiaries in the coal mining sector. With PKP now in operation,
we hope to contribute to local economic development and deliver added value to the company, its
subsidiaries, and all SINI stakeholders.”

This operational milestone highlights BUMA's extensive capabilities as Indonesia's leading mining
services provider. With over 26 years of mining industry presence, BUMA applies an integrated, end-
to-end approach, from mine planning and overburden removal to transportation and rehabilitation,
tailored to meet each site's unique challenges.

With operations officially underway, BUMA is committed to operating safely while delivering strong
results for PKP and continues to explore strategic partnerships and potential contract expansions—
reinforcing the Group’s momentum and long-term growth strategy.
