During the last five years in the first and second phase, 16,600 m of surface diamond drilling and 11,345 m of underground diamond drilling has been proposed and drilled to explore the strike and depth continuity of the existing reefs and its adjacent branches, to explore some of the un-correlated lodes and blind ore shoots.
The evaluation of the exploration data has revealed the continuation of the existing reefs and also occurrence of continuation of some un-correlated lodes in the northern and southern part of the existing Hutti mining lease area. This has enhanced the additional possible ore reserves.
Summary of Drill Proved Reserves
| Drilling | Million Tonnes | Grade (g/t) |
|---|---|---|
| Surface Diamond Drilling | 0.59 | 4.58 |
| Underground Diamond Drilling | 0.88 | 2.43 |
These are categorized under Indicated Mineral Resources (332) of UNFC Norm.
