corundum, Pakistan.12, beryl, emerald, ruby, gems

The Himalayan Mountains in northern Pakistan, though geologically young, host a rich variety of gemstones including tourmaline, aquamarine, topaz, garnet, apatite, emerald, ruby, and sapphire. Mining activity is constrained by high altitudes and harsh weather, limiting operations to a short season. Most deposits are worked by small groups using basic, transportable equipment, often carried by hand or horseback. Notable marble-hosted ruby deposits occur at Ganesh, Gupa Nala, Dhorkan, and Hachinder in the Hunza Valley, where rubies are found in marbles of the Baltit Group, a sequence of metasedimentary rocks. These marbles typically contain phlogopite, margarite, muscovite, zircon, spinel, Mg-tourmaline, pyrite, rutile, and graphite. A newer deposit was also identified near Bisil in the Basha Valley. Pegmatites at Chumar Bakhoor (~4,800 m elevation) have yielded aquamarine and fluorite, while the Stak Nala pegmatites—with about 40 mines—are known for multicolored tourmaline. Hundreds of pegmatites line the steep cliffs along the Indus River, producing aquamarine, black tourmaline, topaz, apatite, and garnet from tunnels reaching depths of 150–180 m. Notably, glacial retreat due to global warming, especially at the Mani glacier, has exposed previously inaccessible gem sites. Pegmatite fields in the Shigar, Braldu, and Basha Valleys cover around 150 km² and lack even basic trails. The absence of modern mining technology, safety protocols, and training poses serious hazards. Rockfalls and landslides are leading causes of fatalities, and approximately 40,000 miners face additional risks such as silicosis and carbon monoxide poisoning. While long-term improvements require infrastructure and education, immediate steps such as using disposable dust masks, portable ventilation, basic first-aid training, and proper climbing gear could mitigate risks. Establishing local gem markets would also help improve selling prices and enhance economic benefits for miners and their communities.
