This project added another feather to team Capstone’s capabilities & endurance under challenging conditions. Objective of the project was to delineate zones of potential iron ore (hematite) occurrence in 05 blocks covering a total of about 09 sq. km.
The task included,

Ground magnetic survey at 100 m line interval and 20 m station spacing for data acquisition.
Identify inferred potential mineralization zones based on magnetic anomaly.
Undertake 2D Electrical Resistivity Imaging over identified magnetic anomaly zones targeting a depth of about 90 m below ground level.
Interpret results & comprehend on tentative resources available in the area.
3-Dimensional model for assessment of the potential resources.
Recommend drilling based verification locations based on above.

The investigation covered more than 4500 Magnetic stations in about 230 LKM of survey. Potential zones were identified in the magnetic anomaly map followed with 2D Electrical Imaging for a total of 72 LKM. The challenges included terrain, vegetation, accessibility, & social conditions. The team overcame all these challenges to complete the project in time. Capstone’s intervention helped client in identifying tentative resource areas, adding to about 50 million tons.
Capstone has undertaken similar jobs for the same client in Barsua Iron Ore Mines in Sundergarh, Odisha.
