Amman Mineral (AMMN) Spends Millions of Dollars on Exploration in Sumbawa

PT Amman Mineral Internasional Tbk. (AMMN) continues to accelerate its copper and gold mining exploration through its subsidiary, PT Amman Mineral Nusa Tenggara (AMNT), in the Sumbawa region, West Nusa Tenggara.

In her statement on Thursday (10/7), AMMN Corporate Secretary, Vemmy Febrianti, revealed that throughout the second quarter of 2025 (April–June), AMMN had disbursed funds amounting to USD 2.85 million for exploration activities.

The funds were used to develop three Special Mining Business Permit (IUPK) areas in addition to the Batu Hijau Block, namely the Elang, Rinti, and Lampui Blocks.

The Elang Block is the primary focus, with an exploration value reaching USD 2.2 million. At this location, AMMN conducted core drilling using three rigs, conducted Induced Polarization (IP) surveys, and conducted geological mapping in three strategic areas: the Elang Cu-Au Project, East Gate, and East Sebu.

During the period, seven drill holes were completed, totaling 3,500.7 meters. This activity included infill drilling at Elang and new exploration at Gerbang Timur.

A total of 1,479 core samples have also been sent to the laboratory for further testing. The IP survey in the Elang Block covered 11 traverses covering 19.7 kilometers, while 135 rock and soil samples were collected from East Sebu for geochemical analysis.

In the Rinti Block, AMNT is preparing a USD 37,700 IP survey to identify the potential for a copper-gold porphyry system beneath the lithocap layer. By the end of the quarter, line preparation had reached 65% of the target, with eight lines totaling 11.35 km.

The main activities next quarter will focus on IP data acquisition and initial exploration drilling using a single rig.

Meanwhile, in the Lampui Block, AMMN has allocated approximately USD 605,000 to support exploration drilling and follow-up IP surveys. Two drill holes have been completed to a total depth of 1,048.2 meters, with the collection of 405 core samples.

A 5.4-km IP survey was also conducted to follow up on previous anomalous findings.
This aggressive step demonstrates AMMN's commitment to expanding the potential of mineral reserves in eastern Indonesia, while strengthening the company's strategic position in the global mining industry.
