With a nominal GDP of USD 108 billion, a Ba1/BB+ sovereign rating, and a Omani Rial pegged to the US dollar since 1986, Oman offers a rare combination of political stability and FX certainty that most emerging-market mining destinations cannot match. The corporate tax rate sits at 15% — dropping to zero inside the Sohar, Salalah, and Duqm Free Zones for the first ten years. Foreign investors can hold up to 49% equity by default, rising to 65% for projects aligned with Vision 2040. The minimum registered capital to enter is approximately USD 390,000. At the strategic heart of the opportunity is Minerals Development Oman (MDO), 76.8% owned by the sovereign wealth authority OIA, which co-invests, provides pre-licensed concessions, and shares geological datasets — materially lowering the cost and risk of market entry.
Oman's endowment spans six commercially significant categories:
Gypsum — A 30-billion-tonne geological resource. Oman exported 12.4 million tonnes in 2024, making it the world's largest exporter by volume. India absorbs 47% of that — approximately 90% of all India's gypsum imports originate from Oman. JSW Infrastructure's USD 530M Shuwimiyyah project is set to expand capacity to 30 Mt per year.
Marble & Granite — Block production surged 72% year-on-year in 2023 to 973,000 tonnes. Omani marble's distinctive colour palette and large block sizes command premiums in the GCC, India, and Europe, with a 7–10 day shipping advantage over Southern European competitors to Indian fabrication hubs.
Copper — January 2025 marked Oman's first copper concentrate shipment in 30 years. The USD 270M Mazoon Copper Project at Yanqul is 35% complete, targeting 115,000 tonnes per annum of concentrate by 2027 from five open-pit mines.
Limestone — 7.4 million tonnes exported in 2024, up 49% year-on-year. The fastest-growing export category by volume, anchored by the Dhofar coastal deposits and Duqm port access.
Chromite — 30 million tonne reserves. South Africa supply disruptions have elevated Oman's strategic value to buyers in China, Japan, India, Germany, Thailand, and South Korea.
Silica / TiO2 — The Mahout deposit holds 47+ million tonnes of ultra-pure silica qualifying for solar-grade applications. A TiO2 processing plant came online at Sohar in Q1 2025, opening a downstream critical minerals pathway.
The Law of Mineral Wealth (Royal Decree 2019) governs the sector under the Ministry of Energy and Minerals (MEM). It provides transparent royalty schedules (2–6% for metallic minerals, 2–5% for industrial minerals), commercial arbitration for disputes, and four licence categories — exploration (3 years, renewable), quarry permits (1–5 years), mining licences (minimum 5 years), and concession agreements (up to 25 years). In 2024, 26 new licences were issued and average processing time was cut to 45 days, down from 90+. An online mineral block bidding platform now allows foreign investors to access and bid for concession blocks directly.
The sector generated RO 114.3 million (USD 296M) in 2024 sales revenue. Gypsum and limestone dominate by volume; marble and copper contribute outsized value per tonne. Beyond direct revenue, the sector supports 15,000+ indirect jobs across logistics, quarrying, engineering, and export services. Sohar and Salalah ports derive significant revenue from mineral export throughput, and Duqm is positioned as the next gateway. Downstream, a TiO2 plant at Sohar, an emerging silica-to-glass cluster, and cement feedstock supply chains are adding industrial depth.
MDO sits at the apex with USD 138M revenue across 17 concession areas covering 23,763 sq km. Below it, established Omani private operators — Oman Mining Company (~USD 84.7M), Desert Enterprises (~USD 65.4M), Al Tasnim Mining (~USD 42M), and International Marble Co. (~USD 18M) — handle quarrying, fabrication, and processing. Foreign strategic partners include JSW Infrastructure (India, USD 530M), Alara Resources (Australia, copper JV), and active offtake relationships with Chinese, Japanese, and South Korean buyers. An SME layer of licensed small quarry operators completes the three-tier structure.
Investment opportunity analysis
Five themes offer entry points across different capital scales and risk profiles:
Copper concentrate (Yanqul Belt) — USD 50–300M; IRR 15–22%; LME-linked; 2027+ ramp via JV with MDO or greenfield concession.
Industrial minerals processing (gypsum/limestone) — USD 20–100M; 8–14% IRR; demand-secured cashflows; JV with JSW/MDO or standalone licence.
Premium marble & granite quarrying — USD 5–50M; 18–25% IRR; high margin per tonne; greenfield quarry licence plus fabrication plant.
Critical minerals — silica/TiO2/chromite — USD 30–150M; 12–18% IRR; energy-transition premium; exploration JV or offtake investment.
Minerals logistics & port infrastructure — USD 50–500M; fee-based USD revenues; PPP with Oman Ports Authority.
Mining is one of four designated economic pillars under Vision 2040. The sector is projected to grow from 1.4% of GDP today to 10% by 2040 — a sustained CAGR of 9–10% over 20 years, the most ambitious minerals diversification target in the GCC. The roadmap moves through three phases: Foundation (2020–2025, institutional reform and first copper exports), Scale-Up (2025–2032, Mazoon copper ramp and JSW gypsum expansion), and Diversification (2032–2040, downstream processing and critical minerals integration). By 2040, total export value is projected to exceed USD 2.1 billion, cumulative FDI in mining is targeted at USD 8 billion+, and active concessions are expected to grow from 17 to 60+.
The overall risk profile is moderate — below most emerging-market mining peers. Commodity price cyclicality (medium) is mitigated by long-term offtake structures. Execution risk on Mazoon and Shuwimiyyah (medium-high) is managed via MDO co-investment and EPC performance bonds. Regulatory risk is low-medium given the stability of the 2019 law and bilateral investment treaties. Infrastructure gaps in the Al Dhahirah interior are offset by an active government roads programme. Geopolitical risk is rated low, given Oman's neutral foreign policy — a structural buffer that has protected the country through multiple regional crises. The OMR/USD peg, which has held for 40 years, is a net positive for dollar-denominated commodity exporters.
Saudi Arabia is the only peer with comparable ambition, but its mineral profile (phosphate, gold, copper) barely overlaps with Oman's core strengths. Turkey dominates marble globally — Oman's response must be quality, colour differentiation, and logistics speed rather than volume competition. Iran holds vast reserves but is effectively locked out of international capital due to sanctions, benefiting Oman directly as the default regional supplier of chromite and copper. Pakistan's Reko Diq copper project (Barrick, online 2028) will add around 400,000 tpa to global supply — Oman's Mazoon project should lock in Indian smelter offtake commitments before that window closes. The UAE competes on logistics, not extraction, and is largely complementary to Oman's upstream position.
Across six mineral categories, Oman holds structural advantages that range from very high durability (gypsum, silica) to high durability (marble, limestone) relative to all credible regional competitors. The five policy levers that will convert those advantages into committed capital are: a national mineral branding programme (Oman Stone, Oman Gypsum) to command the 15–20% premium Turkey's label earns; critical minerals MOUs with Japan, the EU, and India to unlock concessional finance; a dedicated Duqm minerals export terminal to reduce export costs by 12–18%; a downstream processing incentive package targeting USD 1 billion+ FDI into Sohar and Duqm industrial zones by 2030; and a coordinated annual MDO–Invest Oman investor roadshow that halves the investor due diligence cycle from 24 to 12 months.
