Reko Diq sits on the Tethyan Magmatic Arc, a belt of copper-gold mineralization that curves from southeastern Europe through Turkey, Iran, and Pakistan, then onward through the Himalayas into Indonesia and Papua New Guinea. This arc has produced some of the world's most productive mines: Grasberg in Indonesia, Ok Tedi in Papua New Guinea, Sar Cheshmeh in Iran, and the porphyry clusters of Bor and Majdanpek in Serbia. Reko Diq belongs to the same geological family -- a low-grade copper porphyry deposit with an average copper grade of 0.41% and a gold grade of 0.22 grams per tonne. The economically mineable portion has been calculated at 2.2 billion tonnes, with higher concentrations of 0.53% copper and 0.30 grams per tonne of gold. Annual production, once operations begin, is projected at 200,000 tonnes of copper and 250,000 ounces of gold contained in 600,000 tonnes of concentrate.

In 1998, the Tethyan Copper Company -- a joint venture between Barrick Gold Corporation of Canada and Chile's Antofagasta PLC through the Luksic Group -- signed an agreement with the Government of Balochistan for exploration rights. Tethyan held a 75% interest; the provincial government retained 25%. Over the next twelve years, the company invested $220 million in exploration and feasibility studies. When Tethyan submitted its mining lease application in February 2011, the response, nine months later, was rejection. Pakistani officials argued the lease had been secured in a non-transparent manner. Tethyan argued the agreement entitled them to the lease subject only to routine requirements. By November 2011, the project was dead in the water -- or, more accurately, dead in the courts.

Tethyan filed for international arbitration through the International Centre for Settlement of Investment Disputes, the World Bank's arbitration body. The ICSID tribunal ruled against Pakistan in 2017, rejecting a prior decision by Pakistan's Supreme Court. The tribunal calculated damages based on projected profits over 56 years of mining operations. In July 2019, it issued an award of $5.97 billion against Pakistan -- a sum equal to roughly two percent of the country's GDP. The figure landed like a shockwave. Pakistan challenged the award, filed for annulment in November 2019, and secured a provisional stay on enforcement in September 2020. The legal battle dragged on, with hearings extending into 2021. Eventually, the dispute was restructured rather than resolved outright: a new deal was struck, keeping Barrick Gold as operator with renegotiated terms that brought the Pakistani government and Balochistan province back into the project on different footing.

In January 2023, a memorandum of agreement was signed specifying advance royalties and social development funds for Balochistan, with the first payment of $3 million released to the provincial government. The International Finance Corporation disbursed $300 million in April 2025, followed by another $700 million in June 2025. During peak construction, the project expects to employ 7,500 people; once operational, it should sustain 4,000 long-term jobs over a projected 40-year mine life. Production is expected to begin in 2028. For the people of Chagai District -- remote, underdeveloped, largely disconnected from the economic activity of Pakistan's major cities -- these numbers represent either transformative possibility or a familiar pattern of extraction where wealth flows outward while communities bear the environmental and social costs. Which outcome materializes depends on whether the renegotiated agreements hold and whether the promised benefits reach the people who live above the ore.

The Chagai Hills run in an east-west line across Balochistan, a chain of eroded volcanic remnants between the Quetta-Taftan railway line and the Afghan frontier. It is sparse, hot country -- the kind of landscape where the presence of billions of dollars underground feels almost absurd against the surface poverty. Reko Diq is not yet a mine in the conventional sense; it is a construction site, a legal precedent, and a geopolitical flashpoint all at once. The copper and gold remain in the ground, waiting on engineering timelines and political stability. From the air, the Chagai chain looks unremarkable -- tan ridges fading into haze. There is no visible sign of the wealth below, nor of the arguments above. Just sand, rock, and the long shadow of a deal that has taken a quarter-century to reach this point.
