In a high-stakes move that bridges Saudi Arabia’s storied petroleum past with its clean energy future, oil titan Aramco and mining champion Ma’aden have forged a landmark joint venture. Their mission is as ambitious as it is massive: sweep across a vast, unexplored swath of the Kingdom to hunt for the critical minerals that will power the global energy transition.
Covering roughly 182,000 square kilometres—a stretch of land equivalent to nearly 10 percent of Saudi Arabia’s total territory—the deal marks a bold new chapter for the Gulf’s economic diversification. Known as Zone-4, or the Transition Zone, this 100-kilometre-wide corridor running parallel to the Arabian Shield represents entirely virgin territory for both corporate heavyweights.
Under the proposed structure, Ma’aden will retain a controlling 51 percent stake, while Aramco holds the remaining 49 percent, subject to standard regulatory and antitrust approvals. The commercial target sits squarely on copper, the foundational metal for electric vehicles, modernized power grids, renewable generation, and energy storage systems. With copper commanding over 20 percent of the $1.2 trillion global mined metals market, the companies are betting heavily on a sector projected to swell from $250 billion today to more than $400 billion by 2035. Secondary targets will include zinc, lead, and high-demand rare earth elements.
The true edge of this partnership, however, lies in its fusion of legacy muscle and cutting-edge tech. Over nine decades of oil and gas production, Aramco has assembled the largest vault of geological and geophysical basin data in the Kingdom’s history. By marrying this vast database with high-performance computing and artificial intelligence algorithms, the venture aims to rapidly analyze sub-surface data, zero in on high-probability targets, and slash the traditional timeline from initial screening to drill-ready mineral discovery.
“Over 90 years, Aramco has accumulated and analyzed the largest amount of geological and geophysical data ever acquired in a single basin for the Kingdom,” noted Saleh M. Al Saleh, Aramco’s Vice President of Transition Minerals. “This partnership intends to leverage this legacy information to find minerals in the JV area within the basin.”
For Ma’aden, the venture expands an already colossal operational footprint. The company has been aggressively surveying the region to unlock Saudi Arabia’s estimated $2.5 trillion in untapped mineral wealth, recently hitting headlines after discovering 7.8 million ounces of gold reserves.
“Ma’aden has been advancing one of the world’s largest single jurisdiction exploration programs across the Arabian Shield to help unlock the Kingdom’s mineral potential,” said Darryl Clark, Ma’aden Executive Vice President for Exploration. “This joint venture would take that ambition into a new area.”
First previewed in early 2025, the venture transforms Saudi Arabia’s traditional energy architecture into an incubator for the raw materials driving global electrification. As the world clamors for copper and transition metals, Saudi Arabia isn’t just relying on what’s under its sand—it’s using nine decades of data to find what comes next.
