4 4 1f General remarks of inspecting officers on geology, exploration etc No exploration was proposed in the scheme of mining approved on No exploration was carried out during the year Development : Sl.No. Item Propasals Actual work Remarks 2a 2b 2c Location of development w.r.t.lease area Separate benches in topsoil, overburden and minerals (Rule 15) Stripping ratio or ore to OB ratio The name of the Quarries such as Dhobikutumb & Kujam were proposed to be developed in 16 as envisaged in Separate benches in soil & morrum, laterite and Bauxite was proposed to be formed in the year as envisaged in the approved The proposed stripping ratio was for 1: 4.16 in the year as envisaged in the approved The two nos. of quarries in the name of Dhobikutumb & Kujam were developed during the year Separate benches in soil & morrum, laterite and in Bauxite ore zone were made as found during the field visit. The achieved stripping ratio was for 1: 1.77 during 16.

5 5 2e 2f Quantity of overburden generation in m3 General remarks of inspecting officers on development of pit w.r.t. type of deposit etc It was proposed to generate cum. of overburden/was te materials in the year as envisaged in The quarries named as Dhobikutumb & Kujam were proposed to be developed in 16 with concurrent backfilling of the mined out areas. During 16, only tonnes of overburden/waste materials were generated. The Dhobikutumb & Kujam quarries were developed during 16 with concurrent backfilling of mined out areas as per the proposal. The actual generation status of overburden/waste materials were less in quantities against the proposal given in mining due to increased in thickness of the orebody than the proposed. Exploitation: Sl.No. Item Propasals Actual work Remarks 3a Number of pit proposed for production Two quarries named as Dhobikutumb & Kujam were proposed for production in 16.

Grade of sub grade mineral generation The proposed recovery was about 80% of ROM as envisaged in It was proposed to generate cum. of mineral reject from the mine during the year as envisaged in the approved available. It was proposed to generate only 905 cum. of sub-grade material in 16 as envisaged in However the cut-off grade was 40% Al2O3 & 5% SiO2. The reported recovery was about 80% of ROM. During the year no mineral reject was generated as reported at the time of inspection. The low grade/sub-grade materials generated due to the mine excavation was blended with the high grade ore in the process to make them usable. No sub-grade material was generated separately during 16. The sub-grade/low grade materials generated from the mine was blended with the high bauxite in the process to make them salable. available.

7 7 3h Manual / Mechanised method adopted for segregating from ROM The total ROM was proposed be sorted out by hand picking and mechanical screening at the mine site.
