Geological Overview & Extraction

Mineral Concession & Provenance

As global defense, battery, and flame-retardant industries face severe export restrictions on antimony, Balochistan Minerals provides a secure, fully independent supply line from our private stibnite concessions in Washuk and Zhob. Our antimony ore occurs as rich hydrothermal quartz-stibnite veins yielding hand-cobbed high-grade lumps ($35% ext{--}58% ext{Sb}$) characterized by exceptionally low arsenic, mercury, and lead impurities.
