Saudi Aramco and Saudi Arabian Mining Company (Ma’aden) have signed an agreement to establish a mineral exploration and hard-rock mining joint venture covering about 182,000 square kilometres in Saudi Arabia.
Ma’aden will hold a 51% stake in the venture and Aramco will own 49%, according to an Aramco announcement. The partnership will target copper as its primary commodity, with zinc, lead and rare earth elements among the secondary targets.
The agreement covers Zone 4, also known as the Transition Zone, a geological belt running parallel to the Arabian Shield in western Saudi Arabia. The area represents roughly 10% of the Kingdom’s landmass and is approximately 100 kilometres wide, according to reported coverage by The National.
The deal is strategically important for Saudi Arabia, but it remains an exploration platform rather than a confirmed mine development. The shareholders’ agreement and incorporation of the joint venture remain subject to corporate, regulatory and antitrust approvals.
Agreement combines Aramco data with Ma’aden mining expertise
The partnership brings together two capabilities that have traditionally operated in separate parts of Saudi Arabia’s resource economy.
Aramco will contribute decades of geological and geophysical information gathered through its oil and gas activities. The company said it has accumulated approximately 90 years of subsurface data, supported by high-performance computing, artificial intelligence and subsurface modelling capabilities.
Ma’aden will provide mineral exploration, mining and operational expertise. The company already operates across several mining segments in Saudi Arabia, including gold, phosphate, aluminium and base metals.
The intended outcome is to use Aramco’s large subsurface data library to improve the speed and precision of mineral targeting, while relying on Ma’aden to advance field exploration and assess whether discoveries can support commercial development.
Saleh Al Saleh, Aramco’s vice-president of transition minerals, said the company had accumulated and analysed a substantial body of geological and geophysical data from the Kingdom. Ma’aden exploration executive vice-president Darryl Clark said the venture could enable the partners to “move faster” and “explore smarter,” according to The National.
Exploration data and subsurface modelling are central to the joint venture’s targeting strategy.
Copper leads the Zone-4 exploration program
Copper is the primary target because of its role in electricity networks, renewable generation, electric vehicles, energy storage and data-centre infrastructure.
The Zone-4 program will also examine the potential for zinc, lead and rare earth elements. Reported descriptions of the broader geological area have identified possible occurrences of other commodities, including gold, silver, nickel, chromium, tantalum and niobium.
The companies have not disclosed a detailed exploration budget, drilling schedule, target inventory or resource estimate. No commercial copper deposit has been announced as part of the agreement.
That distinction is important for investors and mining suppliers. The size of the exploration area indicates strategic ambition, but it does not establish the grade, depth, metallurgy, infrastructure requirements or economic value of any future discovery.
The next stage is expected to involve systematic geological interpretation, remote sensing, geophysical surveys, field mapping and target generation. Drilling and resource definition would follow only after prospects have been prioritised and the necessary approvals obtained.
Field drilling would be required to test targets generated through geological and geophysical analysis.
A new layer in Saudi Arabia’s supply-chain strategy
Saudi Arabia is seeking to build a larger domestic minerals industry as part of its economic diversification program under Vision 2030.
The Kingdom estimates that its mineral wealth could be worth approximately $2.5 trillion, although such estimates refer to the potential value of geological resources and should not be treated as proven reserves or project-level economics.
Saudi policy aims to increase mining’s contribution to the economy to approximately 240 billion Saudi riyals, or about $64 billion, by 2030, according to The National. The strategy extends beyond the discovery of ore. It includes mineral processing, industrial manufacturing, infrastructure development and the creation of domestic supply chains for materials needed in the energy transition.
The Aramco-Ma’aden venture fits that wider approach in three ways:
| Strategic objective | Role of the Zone-4 JV |
|---|---|
| Resource discovery | Uses a large exploration footprint to search for copper and other minerals |
| Data-led targeting | Applies Aramco’s subsurface data, AI and computing capabilities to exploration |
| Domestic value creation | Supports Saudi ambitions to develop mining, processing and downstream industrial capacity |
Saudi Arabia’s position in the global energy system gives the agreement an additional dimension. Aramco remains one of the world’s largest oil producers, but the company has also been expanding its interest in lower-carbon technologies, industrial materials and transition-related businesses.
Copper and rare earths provide a direct link between energy production and electrification. Copper is required for power transmission and distribution, while rare earth elements are used in permanent magnets for electric motors, wind turbines and other high-performance applications. Zinc and lead support galvanising, batteries, industrial alloys and construction materials.
The JV therefore gives Aramco a route into minerals that are central to future energy infrastructure, while giving Ma’aden access to a broader technical data and technology base.
Exploration scale brings execution challenges
A 182,000-square-kilometre exploration area also creates logistical and technical challenges.
Zone 4 is not a single mine site. It is a broad geological corridor that may contain areas with different rock types, mineralisation styles, access conditions and infrastructure needs. Exploration teams will have to determine where mineral systems are concentrated before any potential project can be evaluated.
The Arabian Shield contains some of the Kingdom’s most important known mineral deposits, but the Transition Zone presents a different exploration environment. The value of Aramco’s data will depend on how effectively information collected for petroleum exploration can be integrated with the geological signatures associated with hard-rock mineral deposits.
AI and machine learning can accelerate target generation, but they do not remove the need for field verification, drilling, metallurgical testing and environmental assessment. The commercial risk remains substantial between identifying a geophysical anomaly and defining a mineable resource.
The companies have also not disclosed how future exploration capital will be funded or whether the venture will pursue partnerships with international mining companies, equipment providers or downstream processors.
Previous plans now move toward formalisation
The current agreement follows the partners’ earlier announcement of plans for a transition-minerals venture. The concept was publicly discussed in 2025 through non-binding heads of terms.
The shareholders’ agreement is a more formal step, but it does not mean that the joint venture is already operating at full scale. Required approvals must still be completed, after which the partners will need to establish governance, technical teams, budgets and exploration priorities.
Reuters reported that the partnership would focus on mineral exploration in Saudi Arabia, with Ma’aden as the majority partner. AGBI also reported the copper focus and the partners’ intention to use the Zone-4 area to pursue energy-transition minerals.
The immediate milestones for the venture are likely to be administrative and technical rather than production-related. These include regulatory clearance, formal incorporation, the publication of an exploration plan and the selection of initial targets.
What mining and metals markets should watch
The agreement arrives as copper markets face a long-term debate over whether mine supply can keep pace with electricity-intensive demand.
Skillings’ copper market outlook highlights the tension between rising grid, electrification and data-centre demand and the lengthy development timelines for new mines. A Saudi discovery would not immediately alter global supply, but the JV could become strategically relevant if it defines a large, high-quality resource and advances toward processing.
For operators, the key indicators will be:
- The date on which the joint venture receives required approvals.
- The initial exploration budget and fieldwork program.
- The number and location of copper targets selected for drilling.
- Any disclosure of grades, mineralisation thickness or preliminary metallurgy.
- Plans for power, water, roads and processing infrastructure.
- The potential role of local or international partners.
- Whether zinc, lead and rare earths remain secondary targets or become material project components.
The partnership also connects with the wider global effort to diversify critical-minerals supply chains. Skillings’ critical minerals supply-chain tracker examines how governments and companies are increasingly focusing not only on mining, but also on processing, separation, refining and manufacturing.
For Saudi Arabia, the Aramco-Ma’aden venture is a step toward building that system domestically. For the mining sector, its significance will ultimately depend on what the exploration program finds beneath the Zone-4 corridor: and whether those findings can be converted into permitted, financed and operating projects.
