1 Schedule-V: Information Memorandum,Summary of the Mineral BlockPart A-General Information about Mineral BlockPoint No.4 - Quantity of Minerals (Grade-wise)Mineral & Total Geological ResourcesEstimated Geological resource as per document is 199.154 Million Tonne of cement grade limestonewith avg of CaO 46.44 %, SiO2 5.96 % &MgO 3.14 %Summary of Core Logs - Annexure-IIChemical Analysis of Boreholes - Annexure-IIIIn the document chemical analysis of 24 Boreholes are provided in which core recovery is only apx. 50 and less than 50% which is not suitable for assessing the right quality of total Geological resource of the block

Percentage of Core recovery is very poor resulting in for bidders to have errors in estimation of quality and quantity of limestone reserves and OB, IB and ore to OB ratio.1) What are the reasons behind poor core recovery %.2) Quality of the lost material will be helpful in understanding the deposit.

The core recovery affects the resource estimation, so we request the resources quantity and quality in exploration report of Information Memorandum shall be modified.

The Upfront payments and performance security payments are linked with the mineral resources, hence amendment will help bidders in taking decision.

The geological resources has been calculated considering 100% core recovery. The core recovery may be less due to mechanical reasons within the department drilling machines. In adjoining areas, core recovery is more than 90% when the drilling was outsourced. There is no possibility of cavity or clay lenses

Poor core recovery cannot tantamount to reduction in quantity of mineral resources.

Further, while bidding the bidder has to take into consideration all the facts and circumstances with his own assessment and wisdom after ground level verification of the block.

Enclosed:- Government notification number F.10(3) Rev-6/2001/19 dated 31-05-2017.





17 Exploration Report - Introduction

It is understood that the notified blocks 3D1 and 3D2 are part of earlier notified block 3D Deh Harima (Jan2016) which was having resources around 291Miot over an area of 941 Ha . Now, these notified blocks have total resources of 354 Miot, over an area of 791.19 Ha. Pl clarify how resources have increased while area is reduced and level of exploration seems to be same.

The notified blocks are part of earlier notified block and in absence of no additional drilling and any data collection in year 2016-17. How the resources have been increased against the reduction in the block area?

Earlier resources were calculatde taking cut-off grade as 42% for CaO. Now, the resources have been re-calculated using cut-off grade of 40% CaO. Therefore, quantity of mineral resources have increased as compared to previous notification.

When block was first notified, the block area was inclusive of the area for ancilliary activities but this time, the area for ancilliary activities has been deducted from the total block area as no end use for limestone has been defined.





18 Exploration Report- Resources Calculation

As per GR, it seems the entire area is mineralized. In such case, no area available within Block for non-mining allied activities such as waste dumping, sub-grade dumping and building related facilities which need non-mineralised area.

Types of Maps/Plans/Sections are inadequate to prepare Mining Plan.

Based on field visit, it is observed that Sarasani block 3B2 has significant encroachment( towards NE side) . How the resources would be mineable is a big question.? Whether, due consideration of such habitants have been taken care while estimating resources?

There is a need to add some non-mineralised area within Block since huge waste/reject need to be dumped within Block over non mineralized areas.

Blocks should be converted to CL or detailed exploration and revised evaluation to be undertaken.Based on the field work it is recommended to convert block 3B2 into CL.

There is a need to add some non-mineralised area within Block since huge waste/reject need to be dumped within Block over non mineralized areas.Block shall be notified and resources shall be estimated with due consideration of exploration category (G3) and other social aspects to increase the confidence level of bidder.

Waste dumping can be back-filled in the mined out area/pits specially where limestone is very thin

Illegal encroachments will be removed by revenue department as per their rules. Department will provide support, to the extent possible.

Since no end use is specified, bidder can set required facility as deemed fit.





19 Exploration Report - Summary of Core Logs(Annexure – II)

The details of mineralized zone and summarized lithology (original lithology based on field report of project geologist) is not correlating . (3D1 block/Bh-HRB10, mineralised zone thickness is upto 43 .50m whereas insummarized lithology, it depicts 31 m ) .

Mineralized zone shall be as per original lithology based on field report of project geologist and shall be accordingly revised. A detailed litholog as persamples / meterage given in Chemical log shall be given.

There should not be any ambiguity/discrepancy in the data provided which reduces the confidence level of the bidder.

Value of CaO is coming out 45.36% in the mentioned zone i.e. 36.00 - 43.50 (as per chemical analysis). Therefore, it is included in resource calculation, but was not reported in the field report of project geologist i.e. in initial summarized lithology report which is based on visual estimation.

20 Exploration Report - Summary of Core Logs (Annexure – II)

What is the reason of Poor core recovery ? It reduces the confidence in estimates.

Whether Govt will compensate, if given quality and quantity is not re-confirmed post Detailed Exploration by the SB ?

Since CR% is upto 40% and hence what is the % confidence level / surety of DMG regarding estimates ?

Complete drilled metreage wise lithologs including respective core recoveries to be shared. Seeing such a poor core recovery during exploration, the category of concession should be changed from ML to CL.ORState to arrange Permission to undertake detailed exploration, post issue of LOI.

Poor core recovery gives a low confidence in the estimated resources – both quality and tonnage.

Please refer to question no. 1 of this document

As per current Mineral Auction Rules 2015, there is no such provision for compensation if quality of quantity are not re-confirmed

Confidence level of the dept. is 100% regarding the resource estimates

Any drilling operation before lease execution can only be done by the department. The LOI holder may pay the department to carry out drilling on his behalf, after taking permission from State Government. In this regard





21 Exploration Report- Chemical Analysis of Boreholes (Annexure-III)
