This has been one of the pioneering projects in the chapters of Capstone\u2019s 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.\u00a0Scope of work catering to the objective included,<\/strong><\/p>\n

    \n
  1. Establishing benchmark referenced stations for observations in a regular grid.<\/li>\n
  2. Undertake microgravity survey occupying the observation stations.<\/li>\n
  3. Generate Bouguer gravity anomaly to identify mineralization zones.<\/li>\n
  4. Undertake 2D Electrical Imaging (Resistivity & IP) on selective zones of bouguer anomaly.\u00a0<\/li>\n
  5. Delineate prospective mineralization zones on 2D section.<\/li>\n
  6. Comprehensive analysis in identifying mineralized bodies (depth\/volume).<\/li>\n
  7. Recommend verification drilling to cross-examine results.\u00a0<\/li>\n<\/ol>\n

    Challenges in the project included, thick vegetation, precarious slopes, old pits & shafts and abandoned underground mines.\u00a0<\/p>\n

    Bouguer gravity anomaly data assisted in identifying areas with dense mass (high gravity anomaly<\/i>) 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.\u00a0\u00a0<\/p>\n

      Being a large area, interpretation of Airborne data helped in narrowing zones of potential mineralization. Analysis of Remote Sensing dataset in genres of LANDSAT & ASTER were analysed for lithology & iron ore signature; Geological & Geochemical Mapping in the identified potential zones (regional scale) assisted in target definition for ground magnetic survey. One of the potential areas was targeted, covering 185 sq km in 3500 LKM of magnetic survey and more than 18500 m of drilling exploration. Resource modelling of the sampled data from the drill holes indicated a 5.4<\/b> million Tons (Mt) of Measured, 7.8<\/b> Mt of Indicated and 32<\/b> Mt of Inferred Resources of Magnetite with an average grade of 25<\/b>% Fe. <\/p>\n

      5. Recommendation for drilling based verification of geophysical results.\u00a0\u00a0<\/li>\n<\/ol>\n

        A total of about 2200<\/b> magnetic stations were observed & data acquired in the coverage area. Several 2D Electrical Imaging (Resistivity) with a total of 3.2<\/b> LKM lead to identification of tentative mineralization pockets. Based on the composite results about 20<\/b> verification drill holes were proposed. With this exercise client could identify additional resources in their existing mines.\u00a0<\/p>\n
