This has been one of the pioneering projects in the chapters of Capstone’s history. The objective was to delineate zones of potential manganese mineralization in a British era abandoned mine in 02 blocks with a cumulative area of about 3.6 sq. km.
Scope of work catering to the objective included,
1.Establishing benchmark referenced stations for observations in a regular grid.
2.Undertake microgravity survey occupying the observation stations.
3.Generate Bouguer gravity anomaly to identify mineralization zones.
4.Undertake 2D Electrical Imaging (Resistivity & IP) on selective zones of bouguer anomaly.
5.Delineate prospective mineralization zones on 2D section.
6.Comprehensive analysis in identifying mineralized bodies (depth/volume).
7.Recommend verification drilling to cross-examine results.
Challenges in the project included, thick vegetation, precarious slopes, old pits & shafts and abandoned underground mines.
Bouguer gravity anomaly data assisted in identifying areas with dense mass (high gravity anomaly) owing to higher density of manganese material. 2D Electrical Resistivity Imaging helped in evaluating the presence, depth & configuration within a complex folded regime. The investigation led to new discoveries of mineralization pockets that remain unexploited in the deposit, paving way to enhanced resource potential in the deposit.
