PT Amman Mineral Internasional Tbk (AMMN), through its subsidiary PT Amman Mineral Nusa Tenggara (AMNT), has officially reported its exploration operational achievements throughout the fourth quarter of 2025.
This strategic move includes intensive activities within the Special Mining Business License (IUPK) area located in Sumbawa, West Nusa Tenggara.
Throughout the period of October to December 2025, the company recorded an expenditure of USD 3.03 million to strengthen its future mineral reserve base.
Based on the information disclosure report released on Saturday, January 10, 2026, the primary focus of exploration was directed at two strategic areas: Block II Elang and Block III Rinti.
These activities are part of AMMN's ongoing efforts to optimize the potential of copper-gold (Cu-Au) porphyry deposits, which are the company's operational strength in the global mining industry.
The Block II Elang area became the main focus of activity, with fund absorption reaching USD 2.8 million.
At this location, AMNT conducted a series of geological mappings and core drillings covering several potential areas, such as the Elang Cu-Au porphyry project, Gerbang Timur, and Sebu Timur.
Additionally, drilling was carried out in the Semamu area, which is projected as a location for waste dump placement.
In its execution, AMNT's exploration management team collaborated with professional partners, namely PT Minera Nusa Drillindo as the drilling contractor, supported by laboratory services from Intertek Utama Service.
Cutting-edge technology, such as the ASD TerraSpec 4 Mineral Spectrometer, was also deployed to perform precise mineral alteration analysis.
Technically, drilling in Block II Elang successfully completed 18 drill holes with an accumulated depth of 6,438.5 meters.
Meanwhile, activities in Block III Rinti absorbed a budget of approximately USD 226,000. By operating one rig unit, the main focus in this block was exploring mineralization potential beneath the Southwest Sane lithocap layer.
By the end of December 2025, two drill holes were completed with a total depth of over one thousand meters. In contrast to the previous two blocks, Block IV Lampui recorded no physical activity or expenditures this quarter, as the company is still conducting an in-depth review of previous exploration data.
The sustainability of AMMN's ambitious projects is supported by a solid shareholding structure involving major players in the national energy industry.
For information, this structure provides an overview of the company's managerial stability and strategic policy direction moving forward.
1. PT Sumber Gemilang Persada (Main Controller): PT Sumber Gemilang Persada holds the position of majority shareholder with an ownership stake of 32.17 percent. With ownership of over 23.3 billion shares, this entity acts as the main controller with significant influence over AMMN's long-term vision. This dominant ownership provides stability in strategic decision-making, particularly regarding large-scale expansion and mine operational integration.
2. PT Medco Energi Internasional Tbk (Strategic Synergy): AMMN's ownership structure is further strengthened by the presence of PT Medco Energi Internasional Tbk, which holds 20.92 percent of shares, equivalent to 15.1 billion shares. The involvement of Medco, which is affiliated with the Panigoro family, creates synergy between the mineral mining sector and energy management. Medco's long experience in the natural resources industry adds value to AMMN in improving operational efficiency and market confidence among institutional investors.
3. Public Participation and Market Liquidity: The public investor group holds an 18.51 percent stake in AMMN's ownership structure. Although each individual or institution in this group holds less than 5 percent, their role is crucial in maintaining stock trading liquidity on the Indonesia Stock Exchange. This distribution of ownership, which includes domestic retail investors and global institutions, reflects healthy market dynamics for the issuer with the ticker code AMMN.
