Geological Overview & Extraction

Mineral Concession & Provenance

The Chagai magmatic arc contains extensive deep-seated igneous plutons yielding exceptional architectural granite in natural pink, speckled grey, and dark porphyritic varieties. Balochistan Minerals extracts heavy monolithic granite blocks characterized by high quartz and feldspar content, minimal micro-fissuring, and extreme compressive strength ($>160 ext{MPa}$) ideal for major infrastructure projects, curb stones, and commercial architectural facades.
