PAKISTAN’s enormous mineral wealth has long lain untapped. Since a 1992 geological survey spotted one of the world’s largest coal reserves in Thar, a scrubby desert in the southern province of Sindh, prospectors have hardly dug up a lump. Among those to flounder is a national hero. Samar Mubarakmand, feted for his role in Pakistan’s nuclear-weapons programme, has just shut the coal-gasification company he founded in 2010, when he vowed on live television to crack Thar.

Environmentalists, many from abroad, argue the reserve’s 175bn-ton bounty should remain underground. They point out the coal is lignite—dirty, poor-quality stuff that, in adding to carbon emissions, increases the risk of climate change for Pakistan. Other critics note that by locking itself into coal, Pakistan may miss out on the plummeting price of solar energy.

To such qualms, the government offers three rejoinders. First, severe power shortages have long blighted the nation, and renewable sources cannot offer the daylong, year-round power it needs. Second, coal accounts for less than 1% of current generation, compared with 70% in neighbouring India and China. And third, domestic coal would allow the country to forgo expensive imports of the fuel for newly built power stations, a drain on fast-dwindling foreign-exchange reserves.

Enter Engro, Pakistan’s largest private-sector conglomerate. The firm’s reputation as a canny risk-taker dates to 1991, when employees bought out its parent company, Exxon, an American energy giant, in the first transaction of its kind in Pakistan. Today, as is common, a single family—the Dawood clan—has a controlling stake. But it has not lost what analysts describe as its “saviour complex”, a desire to address national shortcomings through managerial talent and a balance-sheet plumped by sales of $633m-worth of stakes in its fertiliser-and-food businesses in 2016. Lately that has meant a redoubled focus on energy and in particular on the puzzle of Thar.

Eight years ago Engro bought the rights to one of Thar’s 13 blocks, containing 1% of the reserve (more than enough given the gargantuan size of the mine). To work on extraction, it formed the country’s biggest ever public-private partnership, the Sindh Engro Coal Mining Company (SECMC), in which Engro digs and the state provides infrastructure. Relying on the state can break strong firms. Engro itself almost went bankrupt in 2012 after the government refused to honour a sovereign guarantee to provide gas to one of its fertiliser plants. Yet without similar government support, no other Thar block-owners have secured financing, leaving Engro’s diggers, which began work last year, to move ahead.

The endeavour benefits from being in the group of infrastructure projects that make up the $62bn China Pakistan Economic Corridor, a hoped-for trade route. Western banks shook their heads when approached about a coal project, so Engro has relied on Chinese financing. Analysts note an irony in China’s promotion of coal abroad as it withdraws from the fuel at home. Handling the extraction at Thar is the China Machinery Engineering Corporation, a state-owned firm with expertise beyond Pakistan’s reach.

Around 126 metres below the sands of Thar, with just 20 more to go, Engro’s diggers can now almost touch their prize. When the coal is reached, as is expected in mid-2018, it will feed a pit-mouth power station constructed by Engro, and, in time, three others owned by partners in the SECMC. These stations will furnish around a fifth of the country’s electricity for the next 50 years. The financial rewards could be vast. “All my richest friends are jumping up and down [because they did not get there first]”, says the boss of one big multinational construction business.

Hurdles remain, not least complaints from nearby villagers about the disposal of the vast quantities of wastewater from the mine on their ancestral grazing lands in the form of a reservoir. In reply, Engro stresses its social work in the surrounding district of Tharparkar, the poorest in Sindh, which includes the construction of several free schools. More self-interestedly, it is training locals to drive so they can man the dump trucks that trundle day and night around the mine. According to Shamsuddin Shaikh, chief executive of Engro Powergen, the conglomerate’s energy division, Engro also has its sights on Reko Diq, a gargantuan and long-stalled copper mine in Balochistan, the least developed of Pakistan’s provinces. To tap one of the country’s two largest and most niggardly mines is hard enough. Imagine cracking them both.
