Exploration and Mine Development of Bandalamottu Lead Deposit in Guntur District, Andhra Pradesh

Mineralisation is essentially confined to dolomitic host rock. The strict lithological control of mineralisation with its width extremes and layering defined by the bedding planes in the dolomite and the folding of mineralised zones conforming in style to that of the host rock are strong field evidences to suggest syngenetic origin of the deposit.

Due to structural complexity of the deposit, basic information from 100 m spaced drill intersections does not give correct picture regarding the disposition of ore bodies. No fixed norms for mining could, therefore, be established in advance and every mineralised section will have to be negotiated depending upon the structural domain and allied features governing the mineralisation in that particular section.
