The agenda-wise discussion followed. 22.1: Discussion of the Action Taken Report of the minutes of 21st TCC Meeting held on 26th and
27th June, 2019 The Member Sectretary, TCC, NMET presented the Action Taken Report (ATR) of the 21st TCC meeting held on 26th and 27th June 2019 at GSI, Nagpur. ATR of various agenda points are annexued in annexure-2. 22.2: Evaluation of new proposals: 22.2.1: General Exploration for Limestone in Diggaon Block, District- Kalaburgi, Karnataka. (G2)
i. Mineral Exploration Corporation Limited (MECL) proposed General Exploration (G2) for Limestone in Diggaon Block, District- Kalaburgi, Karnataka.
ii. MECL had submitted the proposal for G3 level exploration which was discussed in 16th TCC of NMET held on 25th September 2018 at Central Region, GSI, Nagpur. Proposal was approved in 10th meeting of Executive Committee of NMET at an estimated cost of 205.98 lakhs.
iii. MECL completed the exploration work and delineated two potential Zones (Zone-I and Zone-II).
iv. Cement grade limestone (Zone I & II) resources of 530.80 million tonnes (Zone-I 400.05 mt & Zone-II 130.75MT) was established under Inferred category (333) with average grade 45.45% CaO, 1.00% MgO & 11.59% SiO2.
v. Average thickness of cement grade limestone varies from 6.40 m to 48.00 m in Zone-I and 13.00 m to 31.80 m in Zone-II. Both the Zones are separated by intervening layer of 50-60m at depth.
2
vi. The continuity and the resource of the lower limestone band (Zone-II) lying ~50m below the 1st Limestone band (Zone-I), was established in the G3 stage itself by drilling 3 boreholes. Since there is a parting of 50m between the 1st and the 2nd zones, the TCC was of the opinion to develop only the Zone-I at G2 stage of exploration only. Accordingly, modification of the proposal, by recalculation of the drilling meterage for each borehole was suggested.
vii. MECL has modified the proposal as per the decision of the committee. viii. The committee recommended for further development of the block in drilling up to the
Zone-I (upper zone) only with borehole grid spacing of 400x400m and restricting the depth of each boreholes up to 50m.
ix. There are 35 boreholes to be drilled in the area, with total drilling of 1750m. The detailed mapping 1:4,000 scale being completed in the G3 stage is sufficient hence, duration for completion of the works and submission of report is set for 12 months at a cost of 319.27 lakhs.
x. Calculation of resource is to be done as per the threshold value of IBM, to be shown separately for both the bands (Zone-I) and (Zone-II done in G3 stage), as per the stage of exploration.
xi. There is no requirement of ore beneficiation for limestone. The Committee recommended the proposal for approval of General Exploration (G2) for Limestone in Diggaon Block, District- Kalaburgi, Karnataka with estimated cost of Rs. 319.27 Lakhs including GST and time schedule of 12 months for carrying out proposed work in G2 stage and submission of report as per Annexure-3A and 3B
22.2.2: Preliminary Exploration for Copper in Deravad area (Part of NMET Block ID: WR-RAJ-02), District- Udaipur, Rajasthan. (G3)
i. MECL proposed Preliminary Exploration (G3) for Copper in Deravad area (Part of NMET Block ID: WR-RAJ-02), District- Udaipur, Rajasthan.
ii. The area was explored by MECL for G4 stage exploration on the basis of surficial investigations and geophysical data and two areas viz. Deravad and Bansra were selected for test drilling.
iii. In the Deravad area, borehole no. MNC-04 has intersected hanging wall lodes of 7.69m×0.99% Cu and 0.82m×0.82% Cu. The other boreholes missed these blind ore bodies.
iv. In the Bansra area, a single lode with 0.59 m of 0.24% Cu has been intersected in the borehole MNC-09. However, the other three boreholes in the Bansra area does not show any potential mineralized zones.
v. The TCC after examining the proposals and detailed discussions, has opined that, since Cu mineralisation is intersected in the G4 stage exploration in 2 out of 5 boreholes drilled, extension of G4 level exploration is suggested in order to ascertain the continuity of the mineralised zones intersected in these boreholes. Since, there is no sufficient data (strike length, width and grade of mineralised zone) taking up of the G3 stage of exploration is not recommended.
vi. The committee suggested for detailed trenching work to be taken up across the strike, collection of channel / groove samples at regular interval depending on the geology, structure to get the strike continuity of these lodes on surface. Based on the encouraging
3
values of the trench values (if any) and correlation of geophysical data three (3) conditional boreholes to be drilled in the North and South Blocks as extension to G4 stage of exploration.
vii. The three boreholes with 60m vertical depth to be drilled (as in previously drilled boreholes at 60m vertical depth) for correlation of the mineralised zone (if any). The proposed depth of these three boreholes at a depth of 140m, 120m and 70m (= 330m) is recommended. Since detailed geological map is available in the G4 stage exploration itself, there is no need to map again. More pitting and trenching in the southern block and channel sampling to be carried out in anomalous zones. Total cost is 92.98 lakhs with a time duration of 7 months for completion and submission of report.
The Committee recommended the proposal for approval as Extension of Reconnaissance Survey (G4) for Copper in Deravad area (Part of NMET Block ID: WR-RAJ-02), District- Udaipur, Rajasthan with estimated cost of Rs. 92.98 Lakhs including GST and time schedule of 7 months for carrying out the proposed work and submission of report as per Annexure-4A and 4B. 22.2.3: General Exploration for Magnesite in Iswal - Selu Block, District- Udaipur, Rajasthan. (G2)

ii. MECL carried out G4 level of exploration in Iswal-Selu-Kathar-Tula (Thala) block, (Block ID WR-RAJ-14) and identified and reported the presence of magnesite. The explored Selu Magnesite prospect area established a resources of 10.045 million tonnes of (Grade 3A and 4 combined Category) magnesite in 16.79 hectares with average thickness of 26.73 meters having MgO 39.76%, CaO 3.46%, SiO2 2.40%, Fe2O3 5.65%, Al2O3 0.23% and LOI 46.94%.
iii. The committee examined the proposal and recommended for taking up exploration as G2 stage exploration, as the boreholes were drilled wherever the exposures of magnesite was present in those areas.
iv. In G2 stage, drilling must be done at a grid interval of 150m x 150m considering the irregular habit.
v. The drilling to be carried out towards the margin of the block wherever the magnesite was established in the previous stage of exploration. No boreholes will be drilled in the areas where the magnesite is not persisting/ vanishing.
vi. Recommended for drilling 43 boreholes with grid spacing of 150x150m and the individual boreholes up to a depth of 30m (as average magnesite thickness is 26m), the total drilling meterage being calculated as 1290m. DM on 1: 4,000 scale with contour interval of 2m covering an area of 1.02 sq.km is suggested taking a time duration of 14 months at a cost of 303.88 lakh.
The Committee recommended the proposal for approval of General Exploration (G2) for Magnesite in Selu Block District- Udaipur, Rajasthan with estimated cost of Rs. 303.88 Lakhs including GST and time schedule of 14 months for carrying out the proposed work and submission of report as per Annexure-5A and 5B.

Usually the size of the exploration blocks for the bulk minerals varies from 4 to 5 sq.km area. Based on the letter from the TN government requesting for smaller areas available for exploration in TN to be taken up in NMET funded projects, the NMET has relaxed the norms to accommodate such blocks and suggested to prepare a block with area of 2.11 sq.km.
i. The amalgamated block with 2.11 sq.km area to be mapped on 1 : 4000 sacle with contour interval of 2m. The boreholes planned in 200m x 200m grid to be modified as 400m grid. Usually for the regular habit of bedded deposits the grids are 400m, as the area falling between mining leases, it must have continuous limestone bands. The depth of borehole must be 60m or 2-3m below the intersection of limestone bed. The influence of block boundary to be taken in to consideration for borehole locations and the borehole location should be 200m away from the boundary of the block.
ii. A certificate to be submitted by Directorate of Mining and Geology, Tamil Nadu regarding feasibility of e-auction of the block after successful completion of exploration work.
iii. The committed had suggested resubmision of the proposal incorporating above suggestions. .
iv. The KIOCL has re-submitted the modified proposal for discussions. v. The three blocks were combined together and made as one signle block of 2.11 sq.km with
detailed mapping on 1 : 4,000 scale with contour interval of 2m, with 18 boreholes to be drilled on 400x400m grid spacing with depth of boreholes upto 60m or upto 2-3m below Limestone bed whichever is earlier. The boundary of the block has been fixed
8
approximately 200m from the boreholes to take effect for the influence of the nearest boreholes for estimation of the reources. The cost of the exploration is Rs. 270 lakh including GST.
vi. The NMET secretariate should ensure that before conveying the approval of the EC, a certificate from the DGM, TN regarding feasibility for e-auction of the block after successful completion of exploration work in that block is obtained.
The Committee recommended the proposal for approval of General Exploration (G2) for Limestone Block in Reddipalaiyam Amalgamated Block, Ariyalur district, Tamil Nadu with estimated cost of Rs. 270 Lakhs including GST and time schedule of 7 months for carrying out the proposed work and submission of report as per Annexure-10A and 10B
