The Partnership That Signals a New Era for Saudi Gold Mining
A significant signal to the Saudi mining market is the consortium between Darkstone Arabia Ltd. and Sinoma CDI . This powerful partnership combines Darkstone’s local execution strength with Sinoma CDI’s international EPC discipline, generating confidence and attracting attention from stakeholders and investors alike.
The consortium, formalized through a Memorandum of Understanding, positions both companies to collaborate on a major gold plant construction opportunity in the Kingdom . This partnership represents a strategic step toward transferring engineering expertise and industrial know-how into the Saudi market, creating tangible value for mining clients operating within the Kingdom.
For Saudi Arabia’s rapidly expanding gold sector—which is central to the Kingdom’s Vision 2030 goal of establishing mining as the third pillar of the industrial economy—this partnership comes at a pivotal moment. Saudi Arabia is targeting a doubling of gold production by 2030, with major projects like the Ar Rjum gold mine (3.6 million ounces over 12 years) and the Mansourah-Massarah gold mine (250,000 ounces annually) driving this expansion .
At Darkstone Arabia, we are proud to lead this partnership, combining our proven track record in Saudi mining infrastructure with Sinoma CDI’s world-class engineering capabilities to deliver institutional-grade gold plant construction.
The Strategic Context: Saudi Arabia’s Gold Sector Expansion
A National Priority Under Vision 2030
Saudi Arabia’s gold sector is at the center of the Kingdom’s mining transformation. With mineral wealth estimated at SAR 9.375 trillion ($2.5 trillion)** , the Kingdom is actively building an integrated mine-to-market ecosystem . The state-owned giant **Ma’aden** has announced a **$110 billion investment plan to triple its gold and phosphate production over the next decade, aiming to elevate the company into the ranks of the world’s top three mining companies .
Key Gold Projects Driving Demand:
| Project | Key Metrics |
|---|---|
| Ar Rjum Gold Mine | 3.6 million ounces over 12 years; 8 million tons/year processing capacity |
| Mansourah-Massarah | 250,000 ounces annually; SAR 105M TSF project |
| Production Target | Doubling gold output by 2030 |
The Infrastructure Imperative
The Ministry of Industry and Mineral Resources is actively addressing infrastructure challenges to accelerate mining development. The Mining Infrastructure Enablement Initiative, launched at the Future Minerals Forum 2026, focuses on providing shared-use infrastructure for remote mining areas—including treated water pipelines and high-voltage electricity connections .
Vice Minister Khalid Al-Mudaifer noted that the cost of developing a new mine starts at $100 million and can reach up to $2 billion, placing significant burden on emerging companies . This is precisely where partnerships like Darkstone-Sinoma CDI add value—reducing delivery risk and accelerating project timelines.

The Market Context: Gold Plant Construction Opportunities
Ma’aden’s Major Gold Projects
Ar Rjum Gold Mine (Makkah Region)
Ma’aden has awarded a SAR 391.1 million ($104.3 million) EPCM contract to Bechtel for the Ar Rjum gold mine . The project includes:
-
3.6 million ounces of gold over 12 years
-
8 million tons/year processing capacity
-
Open-pit mining with advanced processing facilities
Bob Wilt, CEO of Ma’aden, stated: “The Ar Rjum gold mine project represents a milestone in Ma’aden’s journey, as we continue to accelerate the growth of our portfolio. We have big ambitions to expand our gold business, and the Ar Rjum mine is a cornerstone of our plans to double production, accelerate growth, and develop the capabilities to execute our strategy” .
Mansourah-Massarah Gold Mine
Darkstone has already delivered the SAR 105 million Tailings Storage Facility (TSF) for Mansourah-Massarah—the largest TSF in Saudi Arabia—completed six months ahead of schedule. The mine is expected to produce 250,000 ounces of gold annually over 12 years.
