Saudi Arabian mineral exploration landscape in the Zone-4 transition region.
By Sonny Rollins
Saudi Aramco and Saudi Arabian Mining Co. (Ma’aden) have signed a shareholders’ agreement to create a 51/49 joint venture focused on copper exploration and hard-rock mining across about 182,000 square kilometres of Saudi Arabia.
Ma’aden will hold the majority 51% stake, while Aramco will own 49%. The companies said the venture would initially target copper, alongside zinc, lead, rare earth elements and other minerals considered important to the energy transition.
The agreement formalizes plans first outlined in January 2025, but the commodity emphasis has shifted. The earlier framework included lithium and direct lithium extraction (DLE). The latest announcement puts copper at the centre of the venture’s exploration strategy, with the broader mineral portfolio retained as a secondary target.
The scale of the exploration area is significant. At approximately 182,000 square kilometres, Zone-4 covers nearly 10% of Saudi Arabia’s land area. The companies describe it as a roughly 100-kilometre-wide transition zone running parallel to the Arabian Shield within the wider Arabian Platform.
The agreement remains subject to corporate and regulatory approvals, including antitrust clearance. Neither company disclosed capital commitments, exploration budgets, drilling milestones or a timetable for the first resource estimate.
What the agreement establishes
The joint venture is intended to combine two capabilities that have historically sat in different parts of Saudi Arabia’s industrial economy.
Aramco will contribute approximately 90 years of subsurface data, computational resources and artificial intelligence and machine-learning tools. Ma’aden will provide mining, exploration and operating expertise, including the technical capabilities required to advance prospects from discovery through development.
In a joint statement reported by Reuters via TradingView, the companies said the venture would use advanced algorithms and high-performance computing to identify areas most likely to contain copper and other valuable minerals.
The stated objective is to shorten the path from regional geological screening to target definition and discovery. That does not eliminate the normal risks of mineral exploration, but it could improve the ranking of targets across a very large and relatively underexplored area.
The agreement also gives Ma’aden operational control through its majority ownership. Ma’aden is majority-owned by Saudi Arabia’s Public Investment Fund and is the Kingdom’s main mining company, with existing exposure to gold, phosphate, aluminium and other minerals.
Aramco, meanwhile, brings expertise developed through decades of petroleum exploration. Subsurface datasets collected for oil and gas do not automatically translate into economic copper discoveries, but they may provide information on regional structure, sedimentary basins, geochemistry and geophysical patterns that can support mineral targeting.
Exploration drilling and geological sampling are expected to determine whether regional targets can support economic deposits.
Copper replaces lithium as the lead target
The change in emphasis from the January 2025 plan is one of the most important details for mining investors and suppliers.
Lithium and DLE had featured prominently in the earlier concept. Direct lithium extraction is designed to recover lithium from brines without relying exclusively on conventional evaporation ponds, but commercial performance depends heavily on brine chemistry, water management, recovery rates and processing costs.
The latest framework instead identifies copper as the main focus. Zinc, lead and rare earth elements will be explored alongside copper, creating a multi-commodity mandate rather than a single-metal project.
That positioning reflects copper’s role in power grids, renewable generation, electric vehicles, industrial equipment and data-centre infrastructure. Copper demand is closely tied to electrification, while new mine supply faces long permitting timelines, declining grades at some established operations and rising capital requirements.
Skillings’ copper price forecast 2026 analysis examines the market drivers and supply constraints shaping the metal’s outlook. The Aramco-Ma’aden agreement does not add near-term copper supply: exploration, resource definition, permitting and construction would all need to occur before production became possible.
That distinction matters. The announcement is strategically important, but it is not yet a production or reserve announcement.
Announcement versus development milestone
| Item | Position under the agreement |
|---|---|
| Joint-venture ownership | Ma’aden 51%; Aramco 49% |
| Exploration area | Approximately 182,000 km² |
| Geographic setting | Zone-4, or the Transition Zone, within the Arabian Platform |
| Primary commodity | Copper |
| Additional targets | Zinc, lead and rare earth elements |
| Aramco contribution | Subsurface data, AI/ML, computational and high-performance computing capabilities |
| Ma’aden contribution | Mining, exploration and operating expertise |
| Capital commitments | Not disclosed |
| Exploration milestones | Not disclosed |
| Closing conditions | Corporate, regulatory and antitrust approvals |
This framework is a useful reference point for tracking the venture. The next material indicators will be the date of incorporation, the first exploration budget, the release of target areas, drilling activity and any disclosed resource or reserve estimates.
Why Zone-4 matters
Zone-4 sits between major geological domains and extends parallel to the Arabian Shield, a Precambrian geological province known for its mineral potential. The transition setting gives the venture access to a broad range of geological environments, although the size of the licence area also creates logistical and technical challenges.
A 182,000-square-kilometre exploration programme requires prioritisation. Roads, water, power, communications and field camps may be needed across remote terrain. Exploration teams must also distinguish geological anomalies from deposits that can support commercial mining.
The companies’ use of AI and machine learning is therefore likely to be most relevant at the screening stage. Algorithms can process large volumes of geological, geochemical, geophysical and remote-sensing data, potentially identifying patterns that would be difficult to assess manually across such a wide region.
The technology does not replace drilling. It helps determine where drilling may be most informative.
The scale of Zone-4 means regional data analysis will be central to exploration prioritisation.
For operators and equipment suppliers, the programme could eventually create demand for airborne geophysics, drilling, geological modelling, sample preparation, field logistics and digital mine-planning services. Those opportunities will depend on how quickly the JV moves from corporate formation to field activity.
Part of Saudi Arabia’s wider mining strategy
The venture supports Saudi Arabia’s effort to build a larger domestic mining industry and reduce the economy’s dependence on hydrocarbons.
The Kingdom has estimated its untapped mineral wealth at approximately $2.5 trillion and has set a target of increasing mining’s contribution to gross domestic product to about $64 billion by 2030. The government is also seeking a stronger position in global supply chains for copper, rare earths and other critical minerals.
The Aramco-Ma’aden structure aligns with that objective by pairing national industrial capacity with a large exploration footprint. It also places mining within a broader energy and industrial strategy rather than treating mineral development as an isolated sector.
Saudi Arabia has already sought to attract international mining capital through licensing reforms, exploration incentives and partnerships. A successful domestic copper discovery would strengthen the Kingdom’s case as a regional mining and processing centre. However, success will depend on geology, permitting, infrastructure, metallurgy, water availability and the economics of any eventual operation.
The agreement itself does not confirm that Zone-4 contains an economic copper deposit.
What investors should watch next
The immediate question is whether the shareholders’ agreement moves into implementation without delays related to approvals or venture incorporation.
After that, the most relevant disclosures will be operational rather than financial. These include:
- The first priority exploration blocks within Zone-4.
- The size and timing of the initial exploration programme.
- Airborne and ground geophysical surveys.
- Geochemical sampling and drilling results.
- Metallurgical test work for copper, zinc, lead or rare earth mineralisation.
- Infrastructure plans and water requirements.
- Any resource estimate compliant with an established reporting code.
- The division of funding obligations between Aramco and Ma’aden.
The absence of disclosed capital commitments means the market cannot yet assess the venture’s expected spending profile or development schedule. It also means that any copper price forecast 2026 is relevant mainly as a strategic backdrop, not as a basis for valuing a defined Zone-4 asset.
AI-assisted geological interpretation may help the joint venture rank exploration targets before drilling.
For now, the agreement is best understood as a large-scale exploration platform. It brings together Aramco’s subsurface information and digital capabilities with Ma’aden’s mining expertise, while placing copper at the centre of Saudi Arabia’s next phase of mineral development.
The commercial outcome will depend on what the venture finds beneath the transition zone; and how efficiently it can turn regional geological potential into defined, permitted and financeable projects.
