Mineral Concession & Provenance
The Duddar deposit in Lasbela District represents one of the largest sedimentary exhalative (SEDEX) lead-zinc deposits in South Asia. Balochistan Minerals coordinates off-take and export of high-grade sulfide flotation concentrates. Our zinc concentrates feature high grade ($55% ext{--}62% ext{Zn}$) with low iron and silica penalties, while our lead concentrates deliver valuable silver credits for international custom smelters.
