Lithium has been reported in four geological settings in Pakistan: brine lakes in Balochistan, geothermal well brine in Sindh, pegmatites in the northern mountains and clays in the Salt Range. A 2025 concept note by Geological Survey of Pakistan scientists describes these occurrences as potential and gives no resource estimates.

The most recent measurement comes from Sindh, where OGDC tested water from a geothermal well in 2026. In Balochistan, the north and the Salt Range, the evidence comes from geological studies of lake basins, pegmatites and clays.

Geothermal Brine at Wahid Bakhsh, Khairpur

OGDC found lithium in formation water from a high-temperature geothermal well in its pilot geothermal programme in Sindh, The News reported in July 2026. The company plans detailed brine chemistry profiling and resource confirmation studies.

In August, the paper reported a concentration of 275 milligrams per litre at the Wahid Bakhsh well in Khairpur district. OGDCL has signed an agreement with the Pakistan Institute of Nuclear Science and Technology (PINSTECH) to develop technology for commercial-scale extraction of lithium from geothermal brines.

Closed-Basin Lakes in Balochistan and Sindh

Geological Survey of Pakistan geologists Rahat Ullah and Mukhtiar Ghani cite potential lithium brines in closed-basin lakes, naming Hamun-i-Lora and Hamun-i-Mashkhel. Their note also lists the Rann of Kach, a salt marsh along Sindh’s southeastern border that is not shown on the map.

Pegmatites in the North and Clays in the Salt Range

The same note describes lithium-bearing pegmatites and feldspar-rich granites as widespread along the Himalayan pegmatite belt. It names lithium-tourmaline and lepidolite pegmatites at Shengus and in the Shigar valley of Gilgit-Baltistan, and pegmatite areas in the Neelum, Muzaffarabad and Kara valleys of Kashmir. Granite samples from the Hindukush contained 27.5 to 469 ppm lithium. The authors also report lithium-rich hectorite in the clay formations of the Salt Range.
