NHM Brings Rock Samples from Gosowong to Campus, Geology Students at UNPAD Learn Directly from Mining Practitioners

SUMEDANG - PT Nusa Halmahera Minerals (NHM) encourages field-based learning for students of the Faculty of Geological Engineering, University of Padjadjaran (UNPAD). The support was given in Study Club 2 themed Introduction of Hydrothermal Alteration which was held by the SEG Learning Division of UNPAD SC at Bale Rucita Building of the UNPAD Rectorate, Wednesday, May 6, 2026.

In this activity, NHM not only sends practitioners to share mining industry experiences. The company also handed over grants of altered rock specimens and mineralized samples from the Gosowong Gold Mine area, North Maluku.

The specimen comes from rocks around the Gosowong Vein deposit. The rock is a marker or indicator of the presence of economic gold mineralization in the area.

The Gosowong Gold Mine is an NHM operating area that has been one of the important references in the study of gold exploration and mineralization in Indonesia. With this background, the rock samples brought to campus have direct learning value for geology students.

Head of the FTG Quality Assurance Unit of UNPAD, Dr. Aton Patonah, S.T., M.T., who served as the moderator, appreciated the presence of NHM. According to Aton, the presence of industry practitioners is important to bring together campus theory with the needs of the world of work.

"We are grateful for the participation of NHM, it is certainly not easy to present industry practitioners in the midst of operational busy. This also proves that alumni connections are very important as a bridge of collaboration between campus and the world of work," said Aton in a written statement received Friday, May 15.

NHM presented three senior practitioners in the activity. Manager of the Kencana Underground Mine, Bahrudin Abiad, explained the operational practices of underground mines in Gosowong.

The next session was filled by the Exploration Manager of NHM, Rendy Nurdianto. He explained the characteristics of hydrothermal alteration in epithermal deposits with the case study of the Gosowong Gold Mine.

NHM Geological Superintendent, Dharma Irwanda, then discussed the importance of drilling accuracy in mineral exploration to the mining process.

Rendy said that rock samples from Gosowong could help students understand hydrothermal alteration more realistically. Students not only read theories, but also see rock samples directly related to the formation of gold mineralization.

"With the samples of altered rock and mineralized rock from Gosowong, students can see the output of hydrothermal activity related to the availability of economically viable gold mineralization," said Rendy.

According to Rendy, the sample can also be used as a teaching material and reference to understand the characteristics of the alteration zone and the exploration model for gold mineralization potential.

This activity is a meeting room between the campus and industry. Students get a closer look at geological work in the field, especially in reading rocks, understanding alteration zones, and assessing mineral potential.

For NHM, this support is part of efforts to strengthen relations with the education world as well as preparing more qualified geologists to meet the needs of the mining industry. (ADV)
