Nanchang Mineral Systems Co., Ltd. (001360.SZ) recently announced a proposed acquisition of 51% of Indonesian gold company PT. BINA DAYA LAHAN PERTIWI (BDLP). Its core asset is the Hulubalang gold project in Buol Regency, Central Sulawesi, Indonesia. The proposed transaction is an important step in Nanchang Mineral Systems' expansion into overseas mineral-resource development and operation and creates new opportunities for subsequent resource evaluation and exploration development.
As a project partner, GAIA will apply AI mineral exploration and multisource geoscience-data analysis to support further work on gold resource growth, target selection and the potential for a deeper porphyry copper system at Hulubalang.
01An Existing Resource Base with Growth Potential
The Hulubalang gold project lies in Buol Regency, Central Sulawesi, and covers approximately 38.36 square kilometres. Existing geological exploration records identify two important gold orebodies, No. III and No. IV, providing a basis for further resource evaluation, exploration and development.
Orebody III has a stated ore tonnage of approximately 1.1877 million tonnes, containing about 7.71 tonnes of gold at an average grade of 6.49 g/t. Orebody IV has approximately 459,200 tonnes of ore, containing about 4.39 tonnes of gold at an average grade of 9.56 g/t. Both show favorable gold mineralization, and the higher average grade of Orebody IV provides an important basis for extension studies, resource evaluation and development planning.
Beyond known mineralization, the project's potential for further resource growth deserves particular attention. At mineral-system scale, GAIA is focusing on the epithermal gold mineralization and a possible intermediate-to-deep porphyry copper system in the south. Relationships among mineralizing events and structural conditions provide several exploration levels that warrant testing.
Based on existing stream-sediment geochemical anomalies and regional metallogenic conditions, GAIA has developed an exploration concept with potential for more than one million ounces of additional gold resources. This is a forward-looking research judgment indicating the value of systematic further exploration; it is not a confirmed mineral resource. The scale must still be evaluated through geological investigation, geophysics and validation drilling.
02AI Supports Gold and Copper Exploration
For Hulubalang's complex geology, GAIA will integrate regional structure, geochemical anomalies, multisource remote sensing and geophysical records in a comprehensive mineral-system analysis, further studying the spatial distribution and structural controls of gold–copper mineralization and its potential deep continuation.
For gold resource growth, GAIA will combine known orebodies, historical exploration results and stream anomalies to study the extension of gold-mineralized zones and possible enrichment areas, cross-analyse multisource data and prioritize targets that warrant field validation.
At the same time, intermediate-to-deep porphyry copper potential in the south will become an important next-stage direction. GAIA will analyse regional magmatism, ore-controlling structures and associated anomalies to characterize the possible porphyry copper system and move gradually from regional mineral-system understanding to specific exploration tests.
Under the current work plan, the project will soon conduct targeted geophysics and validation drilling. New measurements will test the current geological interpretation, continually refine target priorities and subsequent deployment, and support both gold resource growth and the potential discovery of copper resources.
Mine Construction and Exploration Advance Together
While resource-potential evaluation and deep-target studies advance, preparation for Phase I mine construction at Hulubalang is also under way.
The current Phase I concept is designed for 500 tonnes of ore per day at an average design head grade of approximately 6.49 g/t, with estimated annual gold production of about 1.07 tonnes after ramp-up. These are planning estimates; actual production still depends on resource validation, engineering construction, metallurgical recovery and operating conditions.
The project will progressively prepare mine infrastructure, mining works and supporting processing facilities and continue to refine resource evaluation and mine-development planning as new exploration results arrive.
Hulubalang will seek to combine mine construction with continuing exploration. Development preparation will advance around the known gold resource, while AI analysis and targeted geophysical, geochemical and drilling validation continue to test extensions of known orebodies and the potential deeper copper system. The aim is a coordinated path between resource growth and long-term mine development.
GAIA Helps Increase Mineral-Resource Value
Progress at Hulubalang demonstrates the application value of combining artificial intelligence with mining expertise in resource evaluation, exploration decisions and mine development.
As a technology company focused on AI mineral exploration and mineral-resource value creation, GAIA continues to place AI inside real geological workflows. Multisource geoscience fusion, prospectivity prediction, resource-growth target selection and drilling optimization help mining partners process information more efficiently, allocate exploration resources better and support professional geological judgment with more systematic data.
At Hulubalang, GAIA will deepen the connection between AI analysis and field validation around gold resource growth and intermediate-to-deep porphyry copper exploration, translating technical research into specific exploration action.
GAIA will continue to strengthen technical collaboration with Nanchang Mineral Systems and other mining partners, exploring the use of AI in mineral discovery, resource growth and life-of-mine management and using sustained technical innovation to increase mineral-resource value.
