MDO Opens the Build Tender for Oman's First Bulk Minerals Port. What Al Shuwaymiyah Commits to in Dhofar.

Minerals Development Oman issued a Design and Build tender for the Al Shuwaymiyah bulk minerals port on May 26, opening contractor bidding for a $419 million facility on Oman's southern Dhofar coast. The tender, reported by the Oman Observer on May 26 and confirmed by AGBI on May 27, marks the first formal construction procurement step for what would be Oman's first port built specifically to export industrial minerals at scale.

Key Takeaways

• MDO launched the Design and Build tender on May 26, 2026. Bid submissions close September 6, 2026. (Details below)
• The port is designed for 27 million tonnes per annum of gypsum, dolomite, and limestone exports from Dhofar. (Mineral reserves below)
• JSW Infrastructure holds a 51 percent equity stake in the port SPV; MDO holds 49 percent. The shareholder agreement was signed in November 2025. (JV structure below)
• Port capex is cited at $419 million, with commercial operations targeted for the first half of 2029. (Delivery timeline below)
• MDO's 2025 revenue declined 39 percent, signalling the company is still pre-revenue at operating scale. That context matters for assessing execution risk. (Risks and caveats below)

What the Tender Actually Is

MDO issued a Design and Build procurement package, which means the winning contractor will carry both the engineering design and the physical construction. That integrated route removes the handoff between design and build phases and typically compresses the overall schedule. It also concentrates delivery risk in a single contract, which suits a remote greenfield site.

The port site sits in the Wilayat of Shaleem and Al Hallaniyat Islands, within Dhofar Governorate on Oman's southeastern coast. Dhofar is Oman's largest governorate by area and one of its most geographically isolated from the industrial corridor around Muscat and Sohar in the north. That distance is precisely why the absence of dedicated export infrastructure has kept the region's mineral wealth commercially stranded until now.

Bids close September 6, 2026. MDO has set a commercial operations target of the first half of 2029, implying a construction window of roughly 30 to 36 months from contract award. Whether that schedule is realistic depends heavily on how quickly contractor selection concludes after the September deadline.

The Mineral Reserves This Port Is Built to Unlock

MDO holds concession rights across approximately 1,500 square kilometres in the Al Shuwaymiyah area. The three mineral types the port is designed to handle are gypsum, dolomite, and limestone. Reserve estimates reported by MDO and cited in the Oman Observer are large: 520 million tonnes of gypsum, 1.3 billion tonnes of dolomite, and 2.5 billion tonnes of limestone.

These are industrial minerals, not the copper or chromite that tend to attract more attention in Oman's mining narrative. But global demand for all three is substantial. Gypsum feeds wallboard and cement manufacturing. Dolomite goes into steel production, glass, and soil conditioning. Limestone is one of the most widely consumed industrial inputs on earth, used in cement, chemicals, and agriculture. India, Southeast Asia, and East Asia are the stated primary export markets. JSW Group's involvement is directly relevant here: the parent conglomerate operates large steel and cement businesses that consume exactly these inputs.

How the JV Is Structured

The port will be owned and operated by South Minerals Port Company SAOC, a special purpose vehicle incorporated for the project. JSW Overseas FZE, the international subsidiary of JSW Infrastructure, holds a 51 percent controlling stake. MDO holds the remaining 49 percent.

The shareholder agreement anchoring this structure was signed on November 17, 2025, committing a total investment of OMR 204 million, roughly $530 million at prevailing rates, covering port development and associated quarrying infrastructure across the three concession areas.

What Materially Changed Since the Last Checkpoint

The shareholder agreement signed in November 2025 established the legal and financial framework. That was a necessary step, but it was not a construction step. Issuing a Design and Build tender is different: it is the first formal market-facing action that invites contractors to price the work and commit to delivery. The project now has a bid clock running, and the outcome of that bid process, not the November 2025 handshake, will determine whether the 2029 target is achievable.

Oman's logistics and trade corridor build-out has moved along a similar arc in several other locations recently. The A'Dhahirah dry port, covered in this publication on May 24, followed the same progression from planning commitment to active contractor award. Al Shuwaymiyah is now at the equivalent procurement stage, one step before contract award.

The Delivery Machinery

MDO is a joint venture under the Oman Investment Authority's portfolio, created to develop and commercialise Oman's non-hydrocarbon mineral resources as part of Vision 2040's economic diversification agenda. Its mandate spans the full value chain, from concession acquisition and exploration through processing and now export infrastructure.

The port project sits within the National Programme for Minerals, one of Vision 2040's explicit diversification programs targeting sectors intended to reduce Oman's fiscal reliance on hydrocarbons. How this and related diversification programs are tracking against their stated targets can be followed through Oman Vision 2040's progress indicators.

The delivery sequence from here: MDO evaluates bids received by September 6, awards the contract, contractor mobilises to site, and construction runs for approximately 30 to 36 months targeting H1 2029 commercial operations. MDO has not publicly specified a contingency schedule.

Risks and Bottlenecks

Several caveats are worth watching.

MDO's own financials show the company is still in a build phase rather than an operating phase. Its 2025 revenue came in at OMR 10 million, a 39 percent decline year on year, according to figures cited by AGBI. Total assets grew 22 percent to OMR 227 million, reflecting capital investment, but the revenue contraction signals that mining production and export activity is not yet generating meaningful cash flow. A port designed to move 27 million tonnes annually would require quarrying output far beyond MDO's current operating scale to run at capacity from day one.

The Dhofar location is remote from Oman's existing construction supply chain. Equipment and materials will need to reach a site without existing port infrastructure, adding logistical complexity and cost risk to the build itself.

The September 6 bid deadline leaves limited runway to select a contractor and begin site works within 2026. Any slippage in contractor selection directly compresses the 2029 target. There is no public contingency date.

One numerical discrepancy worth flagging: the Oman Observer cited total project capex at $409 million, while AGBI and reports citing JSW Infrastructure's own release put the figure at $419 million. The gap is small but suggests the final construction cost estimate may still be refined during contractor pricing. This article uses the $419 million figure from the project developer's own announcement.

How This Compares Regionally

Saudi Arabia's Ras Al Khair industrial city on the Arabian Gulf includes dedicated mineral export terminals serving Ma'aden's phosphate and aluminium operations, both running at large commercial scale. However, those handle fundamentally different commodity types in a different geography, and a direct cost or throughput comparison with Al Shuwaymiyah would not be meaningful. The Saudi facilities were also built over more than a decade of phased investment and are not a useful benchmark for a new greenfield project.

The UAE has no direct equivalent. Fujairah handles fuel oil bunkering and general dry bulk, but the UAE has not developed a dedicated industrial minerals export port from its own resource base. In that narrow sense, Oman's move is distinctive within the GCC, though it will take until at least 2029 to test whether the export model works at the scale the project targets.

Why This Matters for Oman

Dhofar's industrial mineral wealth has featured in government strategy documents for years. The obstacle has always been infrastructure: without a deepwater export facility, the economics of moving bulk low-value-per-tonne minerals across long distances do not close. A dedicated port changes that equation by collapsing per-tonne logistics costs and opening direct Indian Ocean access to India and Southeast Asian markets.

For Vision 2040's diversification targets, this project represents the kind of concrete step that converts a resource endowment into a tradeable export and an employment story for a governorate that has historically received less industrial investment than the north. The Design and Build tender launch does not guarantee delivery, but it does mean the project has crossed from the announcement pipeline into the procurement pipeline. That is a different kind of commitment.
