The area is well connected by the road network. Mining lease area is about 5 Km from NH 08 and about 13 Km from Tehsil- Kotputli which is located on National Highway no. 08. Letter of Mining lease is attached as Annexure -I (ii) Brief description of nature of the project. M/s National Limestone Co.Pvt.Ltd proposes to increase the production of limestone from 99325 tonnes to 0.8 MTPA tonnes and the project proposal comprises of the following: 0.80 Million TPA Limestone Mining DETAILS OF LIMESTONE MINE ARE GIVEN BELOW The deposit is accessible at a distance of 5 kms from Gordhanpura Chowki located in National Highway No 08. Gordhanpura Chowki is at a distance of 112 kms from the district head quarters Jaipur on Jaipur –Delhi National highway No 08 The mining lease area is located at a distance of 45 Km from Dabla railway station which is on the Delhi – Udaipur main line of North Western Railway. The area is well connected by the road network. Mining lease area is about 5 Km from NH 08 and about 13 Km from Tehsil- Kotputli which is located on National Highway no. 08. Present Exploration status In order to know the subsurface behaviour of the limestone band core drilling was carried out in 2007 and 2010. The total meterage drilled works out to 1613 mts with 11 bore holes. 4 Eastin Northin Bearin BH No g g Depth Angle g 60866 BH 1 3 3060591 117 45 S50E 60846 BH 2 7 3060316 102 45 N30W 60847 BH 3 5 3060304 130 45 S30E 60759 BH 4 3 3059392 108 50 N30E 60937 BH 5 0 3060765 204 45 N30E M/01/1 60957 0 6 3060613 150 50 N M/02/1 60960 0 3 3060780 200 45 N10 E M/03/1 60955 0 5 3060900 143 45 N93 E M/04/1 60854 0 9 3060497 171 50 S46E M/05/1 60976 0 5 3060695 176.5 50 N M/06/1 60792 0 5 3059396 111 50 N Total meterage 1613 m Geological Cross-Sectional Area Method The basic input in this method is demarcating the various features of the area followed by the preparation of the cross-sectional profile. The profiles are nothing but the line of intersection with the topography generated with GPS. The profiles were then converted into geological sections by incorporating the geological contacts as intersected by the geological mapping and drill hole data. The major lithological formations encountered viz. Overburden soil. Limestones, Calc silicate, Dolomite were marked in the profiles and geological sections were created. The limestone based on the chemical analysis of the borehole cores were subdivided into 1. Limestone 2. Low grade limestone and 3. Rejects within limestone. The Geological Sections prepared in this way were utilised to calculate the sectional area of the different lithological units. The average cross sectional area was then multiplied by distance to arrive at the volume between the two sections. The volume so determined was converted to weight in tonnes by applying ‘volume to weight’ ratio commonly referred to as ‘tonnage 5 conversion factor’ (TCF). The TCF was taken as 2.5. Limestone of Mohanpura varies in orientation from place to place due to the folding and overturning. In Block I the deposit shows a gentle dip of 25 o to 45 o whereas in Block II and Block III the dips are sub vertical to vertical. Thus the true thickness of the limestone lies between 80- 100 m, but due to variation in dips it covers different widths in different areas. Keeping the safety zones of 100 m from the villages which overlap the mining lease and 15 m safety zone from ML boundary, the actual Mineable resources has been calculated through conventional cross –sectional area method. The resources thus calculated have been treated as “indicated resources”. Tonnage Conversion Factor One cubic meter of in-situ Limestone by weight has been considered to be equivalent to 2.5 tonnes of Limestone by weight. Block I For the purpose of calculation of mineable resources through section line GG’, LL’ and MM’ safety zone of 100 m towards Ajeetpura village in south- western part and a 100 m safety zone towards Kujota village in north- eastern part has been kept. Total strike length of 485 m has been taken for resource calculation. A village road connecting Ajeetpura and Kujota passes from the lease block, which has to be diverted to win maximum ore. Block II This is the block where the mining activities are being carried out at present. For the resource calculation, a total strike length of 450m has been taken leaving a safety zone of 100m in north east for Ajeetpura village. Block III The major part of the block is blocked for resources as the Bhaislana village is situated on a part of it and a safety zone of 100 m is to be kept from ultimate pit boundary. Thus a strike length of only 120 m could be taken for estimation of resources. 6 Summary of the geological Vs Mineable resources in 3 blocks of National Limestone Co.Pvt.Ltd Block Limestone (T) Subgrade Waste Rock (T) Limestone (T) Geologic Mineabl Mineabl Geologi Mineabl Geologi al e e cal e cal I 2848086 167742 604625 1332712 2073875 2542262 2 37 .5 .5 II 1427770 684540 760000 3037275 2613259 8902362 2 0 .5 III 4144450 174090 0 0 2179950 1868100 0 Total 4690301 253605 1364625 4369988 6867084 1331272 4 37 5 MioT 46.90 25.36 1.36 4.37 6.87 13.31 Resource calculation of different blocks of deposit Block SL BH Rock Sect.
