REPORT ON GENERAL EXPLORATION FOR GOLD MINERALISATION IN CHAKARIYA BLOCK, TEHSIL- CHITRANGI, SINGRAULI- DISTRICT, MADHYA PRADESH. STAGE (G-2) 63L/11(PART) Field Season: 2016-17 By Gladson Bage, Senior Geologist Abhinav Om Kinker, Geologist

ABSTRACT

Exploration for Gold Mineralization in Chakariya block, Sidhi (now Singrauli) District, Madhya Pradesh was carried out during FS 2016-17 under the item “General Exploration for Gold Mineralization in Chakariya block, Sidhi District, Madhya Pradesh” vide item no. 054/ME/CR/MP/2016/044. The objective of the investigation was to assess Gold resources and associated sulphide mineralization. The exploration involved drilling of 855m, core sampling of 100 nos, petrochemical sampling of 10 nos, petrological studies of 20 samples, bed rock sampling of 50 nos, EPMA 10 nos and SEM-EDX 10 nos. A total of 50cum pitting/trenching was also carried out with the collection of 50 PTS samples. In view of the recommendation by Jha et al (1999-2001), G2 stage investigation was taken up during FS: 2016-17, with two boreholes of closed spaced drilling (50m borehole interval) at 1st level to confirm trench values and to check the strike continuity of mineralized zone of adjacent boreholes and five boreholes of 2nd level of 100m vertical intersections to examine the depth persistence of gold mineralization for better resource estimation and augmentation of already estimated resources. The investigated area belongs to Dudhmania Formation Mahakoshal Group of rocks, which comprises greenish phyllite, areanaceous phyllite, mixed and oxide-silicate facies BIF. The general trend of foliation is N65°W-S65°E to E-W with steep dip towards either side. Predominantly there are three varieties of quartz veins in the block viz. Grey to black coloured quartz veins (QVG), White coloured quartz veins (QVW) and mixed grey to white quartz veins (QVM). The QVW veins are comparatively thicker (up to 6m) while QVG and QVM have 25cmto 50cm and occur as irregular and discontinuous bands mainly within phyllites and rarely in BIFs. The vein type gold mineralisation appears to have been formed during the deformation and low-grade metamorphism. Quartz veins are co-axial with the phyllite though at places it cuts across the phyllite.

Among various quartz veins sampled, one sample from Chakariya block has reported Au value of 8.8 ppm. This confirms that Chakariya prospect has epigenetic auriferous quartz veins. White quartz veins/Grey quartz veins/Mixed quartz veins are intruded into phyllite along S1 foliation planes. These quartz veins are containing specks and stringers of sphalerite, pyrite, chalcopyrite, arsenopyrite and some mineralization occur in the form of vug filling. The emplacement of quartz veins along the foliation planes and its further fracturing and folding at places is suggestive of structural control on the occurrence of mineralization. Arsenopyrite (including its altered form scorodite), pyrite, chalcopyrite and galena are the principal sulphide minerals observed in the mineralized zones in the surface and in drill cores. Emplacement of silica rich melt has taken place along foliation plane S1 and formation of quartz veins with subsequent precipitation of sulphide minerals in the form of vugs filling, pecks and stringers. Deformation of quartz vein initiated the second stage of mineralisation. Along the deformation planes the hydrothermal fluids circulated and subsequent precipitation of sulphide mineralization took place along with silicate phases viz chlorite. Later stage of mineralization is manifested by precipitation of sulphide minerals along the fracture planes which are cross cutting the foliation plane. Gold bearing quartz veins indicates epigenetic nature of mineralization Two main events of deformation have been noticed which are responsible for the regional WNW-ESE trend of the Mahakoshal rocks and the third deformation is mild in intensity and developed at high angle to the first two deformations The planar parallel and continuous geometry of bed and laminations in phyllite indicates stable depositional conditions. This type of geometries is typical of distal turbidite successions. The sulphide minerals comprise arsenopyrite, galena, pyrite and chalcopyrite as primary sulphides and scorodite as weathering product of arsenopyrite. Scorodite is manifested on the surface in the form of discontinuous bands trending WNW-ESE and was observed at many places in the field including NE of Borehole GCD-07, in Trench CT-9, North of Boreholes GCD-01 and GCD-04. The water of Chakariya Block is more or less neutral in nature with pH ranging from 6.70 to 7.44. The TDS is well within range of drinking as well as agricultural purposes.

A total of 855 m of drilling was carried out by 07 boreholes. Two boreholes of 50m vertical interval have been planned in between GCD04 & GCD01 and GCD05 & GCD03 to confirm the trench values and also to check the strike continuity of mineralized zone. The second boreholes of 100m vertical intersection has been planned for GCD-01, 05, 06, 07 and 08 to examine the depth continuity of mineralized zone intersected in first level (50m). It has been observed there is limited lateral continuity between mineralized zones of different boreholes. Petrochemical analysis has been carried out by pressed pellet method. High values of barium 2408mg/kg has been observed in one sample of phyllite. Anomalous value of barium may have come as substitution for potassium in alkali feldspar present in phyllite. Analytical results of scorodite band samples shows less amount of SiO2 and relatively high Fe2O3 content as its common hydrated iron arsenate mineral. The weight ratios of SiO2/Al2O3 against (Na2O+CaO)/K2O show positive correlation and suggest the greywacke and argillaceous source for the deposition of rocks of Dudhmania formation. Dudhmania Formation of Mahakoshal Group of sediments can be classified as arkose and lithic arenite. The high content of Na2O and K2O appears to be due to the predominance of albite and K-feldspars in the sediments. Metasedimentary samples under study are classified as quartz rich with K2O/Na2O>1. The quartz rich samples suggest the passive margin settings of their deposition. EPMA analytical results suggest that Gold and Silver grains are associated with the sulphide phases. The spot values of gold have been observed associated with bismuth ranges from 0.11% to 63.37% and found in association in arsenopyrite. There is association of Zircon, Monazite,Thorium and Xenotime of REE phases. REE represents incompatible phases which are concentrated in rocks formed during later episodes of magmatic crystallization. REE phases are mostly present along the fracture planes which may have come as later stage of crystallization. Statistical analysis of core and bed rock samples in chakariya block supports the corollary of Bi- As-Au association. Corona strucure with pyrrhotite rimmed by pyrite which is formed as an alteration product of pyrrhotite, also occuring along the margins and fracture within pyrrhotite. It also suggest partial or completely replacement of pyrrhotite by pyrite. Most of the suphide phases observed during the EPMA studies are anhedral having irregular and blurr margins suggesting rapid cooling of hydrothermal solution and subsequent haphazard growth of suphide phases during cooling.

iii

In chakariya block Au occurs alongwith an altered form of arsenopyrite called scorodite and along secondary foliaton of phyllite and primary foliations (banding) of BIF. The source of gold in phyllite and BIF is also a result of perculation of hydrothermal emanations along foliation planes ( whether primary or secondary) of these rocks.

The Au values of BRS samples of scorodite band indicate high values between 2.06ppm to 9.16ppm. Au values in quartz vein grey ranges from 0.72ppm to 2.39ppm. The values of Cu ranges from <10ppm to 760ppm, Pb from <10ppm to 210ppm, Zn from <10ppm to 120ppm, Co from <10ppm to 50ppm, Ag from <01ppm to 10ppm and Ni from <10ppm to 100ppm.

A total of 27023 tonnes of ore with an average grade of 1.81 g/t has been estimated for drillholes from cross section method and a total of 24334 tonnes of ore with an average grade of 1.81 g/t has been estimated for drillholes from LV section method. Cumulative resource estimation for Gold for boreholes drilled during FS 1999-2001 and FS 2016-17 at Chakariya Block is 137782.5 tonnes with an average grade of 1.32 g/t.

(after Jha et.al)

Large scale geological mapping of an area of about 25 sq km on 1:10,000 scale was carried out in parts of toposheet no. 63L/11 forming western extension of Chakariya gold mineralised belt, Sidhi district, M.P. The rock types present are phyllite, tuffaceous phyllite, Banded Iron Formation, Banded Ferruginous Chert, ferruginous phyllite with lenticles of Banded Iron Formation and lensoidal bodies of amphibolite rocks of Dudhmaniya Formation of Mahakoshal Group. The gold mineralisation in western extension of Chakariya gold mineralised belt is associated with phyllite interbedded with chert and BIF sequence of Dudhmaniya Formation. It seems to be syn-sedimentary, remobilised along foliation planes and along fold closures during F1 deformation, further remobilization of mineralised quartz veins emplaced during second phase of deformation. The gold values of 0.8 gm/t and 1.2 gm/t (F.A.) are recorded from the BIF band in between Bagaiya – Dhaurahwa area. Presence of gold in bed rock samples in the Chakariya area in the eastern part of Sidhi district was indicated by (Banerjee and Keshava Prasad, 1997) The Geochemical mapping was carried out by Bage et al. (2016) in Toposheet No. 63L/11 and 64I/05 (B1-Quadrant) in parts of Sidhi district of Madhya Pradesh and Mirzapur district of Uttar Pradesh. During the field work a total of 800 sq. km. area was geochemically mapped on 1:50,000 scale with the collection of eight hundred (800) stream sediment/slope wash samples on 1 km X 1 km gridding pattern. Ten (10) soil C-horizon samples, ten (10) Regolith samples, ten (10) water samples and ten (10) HMS samples are collected from every 5‟ x 5‟ gridding pattern. Ten (10) PS and ten (10) XRD samples were also collected from important litho units present in the area II. Details of aero-geophysical and Geophysical mapping, if any Aero-geophysical and Geophysical Mapping in parts of Chakariya block has not been covered yet. III. In case the area forms part of the area covered earlier by exploration then same should be shown in a map with proper scale.

Detailed Mapping was carried out during FS 1999-2001 by Jha et al. A total of 1.0 sq km area was mapped on 1:1,000 scale. The 1:1,000 scale was selected for bringing out the minute details particularly pertaining to the quartz veins which are very thin in nature. The topographical map on the same scale was prepared with contour interval at 2m. The maximum height in the area is around 414.00m above m.s.l. and the minimum elevation is 348.00m above m.s.l. represented by southern slopes of the Chakaria block. The detailed map is shown in plate-I.

V.GEOSCIENCE INVESTIGATION:

V.01: Regional Geology

V.01.1: Brief Regional Geology

Mahakoshal Supracrustal belt: The ENE-WSW trending Mahakoshal supracrustal belt is a prominent fault controlled asymmetrical rift basin (Roy and Bandyopadhyay 1990) (GSI Bulletin Series-A , No. 61), which occur in the northern part of the CITZ. It is bounded by SNNF in the north and SNSF in the south and extends for more than 600 km along strike. SNNF separates the Mahakoshal belt from the Proterozoic Vindhyan basin in the north, with intervening local slivers of Sidhi gneisses, which is regarded as the equivalent of Bundelkhand granite. SNSF separates the Mahakoshal from vast expanse of Proterozoic granites and gneisses of CITZ and is covered for the most part by Deccan Trap, Gondwana sediments and Quaternary alluvium. According to Roy et al Mahakoshal rift basin (ca. 2.2) may be a back-arc rift related to north-directed subduction of the oceanic crust of the BC below BKC. The magmatism coupled with the contractional tectonic setting and accompanied low pressure metamorphism suggests that the Mahakoshal Basin might have initiated as a back arc rift in BKC. According to Devrajan et.al 2002, The Mahakoshal supracrustals were thrusted northerly along the two bounding faults, SNSF and SNNF and the syn-depositional Amsi -Jiyawan fault. Large scale denudation of the evolving and uplifting fold belt led to the deposition of the Vindhyan Supergroup in the foreland basin to north. Inversion along syn depositional Amsi –Jiyawan fault led to the deposition the lower part of the Semri Group, i.e., the „Jungel Group‟ initially by slope processes and subsequently by braided rivers over part of the evolving Mahakoshal fold belt itself. The Mahakoshal Belt is dominated by metasediments with subordinate metavolcanics mainly of tholeiitic composition. The spatial distribution of the rocks in the Mahakoshal Belt shows considerable variation. The lithoassemblage of the Mahakoshal belt is represented by quartzite- carbonate-chert- BIF-greywacke-argillite-mafic volcanics. According to Roy and Devrajan (2000), the Mahakoshal belt was initiated as pericratonic basin along the southern margin of the BKC, in which shallow marine quartzite-carbonate-pelite-chert –BIF were deposited. Subsequently, the basin underwent rifting aided by thermal doming, which resulted in emplacement of tholeiitic magma. Uplifting of the rifted margins led to the deposition of debris flow deposits, which culminated in the deposition of the argillite-BIF during the thermal 9

relaxation stage. Lithological and geochemical characters clearly indicates a continental rift setting for the Mahakoshal basin. Lithofacies distribution points to asymmetrical rifting and younging of the basin towards south, (Roy and Devrajan, 2000). The rocks of Bundelkhand Craton which forms the basement of Mahakoshal supracrustal belt, yield Rb-Sr ages upto ca.2.2 Ga ( Sarkar et.al 1995). Thus the rifting may have post dated ca. 2.2 Ga. (A. Roy et.al 2003). Detailed account of lithostratigraphy and structure has been dealt by several workers viz. Goyal and Jain (1975), Mathur and Narain (1981), Nair et al., (1995), Bandyopadhya et al., (1995), Roy (2000), and Tripathi et al (2013). The Mahakoshal sequence in southern parts between Dudhi and Gulaldih described by earlier workers under Parsoi Formation (Goyal and Jain, 1976) are reinterpreted by Khan et al., (1994) as chemogenic sediments representing older Agori Formation. This sequence is also referred under Dudhmaniya Formation (Roy and Devarajan, 2000). Mishra and Tripathi (1990) carried out mapping in T.S. No. 63L/3 and 11 on 1:50,000 scale and opined that Mahakoshal Group of rock was developed in rift environment during Late Archaean - Early Proterozoic.

V.02: Detailed Geological Exploration: V.02.1: Detailed Mapping on 1:1000 Scale The description of detailed mapping is included in previous exploration along with map. V.02.2: Description of Rock Types: Important lithologies observed in the block are: 1. Phyllites 2. Banded Iron Formation (BIF)/ Banded Ferruginous Chert (BFC) 3. Quartz veins, 4. Scorodite

Phyllites: Phyllites are the most dominant litho unit exposed. The green phyllites occupy the southern and western part while arenaceous/slaty phyllites occur towards the north-central part. Near the BIF/BFC and phyllite contacts, ferruginous/brecciated phyllite bands are present. Green phyllite: Khaki-green to dark-green coloured, well-foliated phyllite is the main constituent of the argillite suite of rocks. It is extremely fine grained mainly composed of plagioclase, relict hornblende, biotite, quartz and iron oxides. The green phyllite with well developed foliation planes, is the most favourable hosts for quartz veins. Tuffaceous phyllite: Reddish-grey to greyish-white, less foliated, friable, tuffaceous phyllites occur in association with either ferruginous phyllite near CT-01

Longitude: 82°44´5.5 ´´ latitude: N24°16´57.1´´ Arenaceous/slaty phyllite: Dark greyish-green arenaceous phyllite, hard and compact, with well developed slaty cleavage, occupies the north-central part of the block. Large outcrops of arenaceous phyllite are 12

prominently present in the block due to its hard nature. As compared to the green phyllite, arenaceous phyllites are less traversed by quartz veins. Arenaceous phyllite contains greater amount of quartz grains

2. BIF/BFC:

Prominent long, narrow, linear ridges of BIF/BFC in northern part of Chakariya block. They stand out prominently due to their hard nature as compared to the surrounding phyllites. Hence they represent highest elevation in this block. BIF are the most characteristic sediments in the „Greenstone/ Sedimentary Belts‟ and are referred to as any sedimentary rock whose principal chemical characteristic is anomalously high content of iron (Trendall & Morris,1983). Oxide Iron Formation is most dominant BIF in this block where alternate bands of white to greyish chert and magnetite and/or haematite constitute BIF. The thickness of individual chert band varies from 50cm to 2m while the magnetite/haematite layers range in thickness between 1cm and 5cm. Asymmetric micro-fold was observed in BIF wherein hinges are eroded and limbs are preserved. Bearing of BIF in this section is 106°/86° towards NE.

3. Quartz veins:

Quartz veins of varying dimension and colours are present in the Chakariya Block. Predominantly there are three varieties of quartz veins in the block viz. Grey to black coloured quartz veins (QVG), white coloured quartz veins (QVW) and mixed grey to white quartz veins (QVM). The QVW veins are comparatively thicker (up to 6m) while QVG and QVM have 25cm to 50cm and occur as irregular and discontinuous bands mainly within phyllites and rarely in BIFs. The quartz veins are generally aligned parallel to the regional foliation direction i.e. WNW-ESE but it is also noticed that few small quartz veins cut across this direction especially north of GCD-07.

4. Scorodite:

Khan et al., (1994) reported occurrence of scorodite as a path finder for gold mineralisation, for the first time in an auriferous zone of Gulaldih area. In Chakariya Block Small, isolated, discontinuous outcrops of scorodite are present all along 700m strike length in WNW-ESE direction between trenches no. CTE-4 -  T-14 in the east through south of  T-16,  T-21,  T- 23 and upto  T-56 in the central part. Scorodite band is in contact with the BIF band in the west and in the eastern side it is associated with ferruginous/tuffaceous phyllites. It is probable that the scorodite band is at the contact of phyllite/BIF units. Such scorodite bands occurring near the interface of incompetent/competent rock units are favourable loci for gold mineralisation. Scorodite is a supergene mineral, resulting from the oxidation of arsenopyrite and other arsenic bearing minerals and therefore can be used as a pathfinder mineral for gold. Scorodite is hydrated iron arsenate mineral. It is found in hydrothermal deposits which ultimately weathers to limonite (Field Photograph-III).

V.02.3: Petrological and petrochemical studies, Studies including SEM-EDX, EPMA, Whole Rock analysis & Trace Element Chemical Analysis.

Petrological studies: Under microscope the phyllite is fine grained and shows well developed foliation plane defined by quartz fish and muscovite/sericite. The photomicrograph of phyllite with quartz fish grains shows dextral sense of movement (Photomicrograph- I and II).

All minerals in the photographs showing very high reflectance. There is fracture filling in the host. 18

EPMA: Electron probe microanalyzer (EPMA) or Electron Micro Probe Analyzer (EMPA).

Mineral chemistry of sulphides in the major lithounits was studied through electron probe analysis. This analysis permits for the quantitative measurement of the samples in terms of variation in chemistry within a single grain and identification of different phases. The EPMA analysis was carried out in National Centre of Excellence in Geoscience Research Lab, Bangalore. The instrument was operated at 15 kV acceleration voltage and 15 nA current for analyzing silicates and 20kV acceleration voltage and 20 nA current for sulphides. The analytical results are given in Annexure-XV-A-E. Lithounits like Phyllite, Arenite were selected and probed for the identification of different sulphide phases and associated PGE phases. The electron probe analysis of arenite, arenaceous phyllite and quartz vein was carried out to identify different sulphide phases. Majority pyrite, pyrrhotite, arsenopyrite and chalcopyrite define sulphide phases (Photomicrograph nos XIX,XXI,XXII,XXIII,XXIV,XXV,XXVI,XXVII, XXVIII). In charakriya block association of gold occures with sulphide phases of Arsenopyrite, Pyrite,Cpy and Po. Gold in Chakariya block does not occur in native form but occurs as nano- sized grains (not visible with naked eyes or microscope) embedded within micro-grains of ususally arsenopyrite and others.

Photomicrograph no.- XIX: BSE image showing association of Arsenopyrite (Apy) with grains of Gold (Au) and Bismuth (Bi) in Quartz vein Grey in slide no.05

Gold and silver grains are seen associated with the sulphide phases. The spot values of gold have been observed associated with bismuth ranges from 0.11% to 63.37% and found associated with arsenopyrite. (Photomicrograph no. XX).

Photomicrograph no.- XXII: BSE image showing association of Pyrrhotite (Po) and Pyrite (Py) in Quartz vein Grey.

Photomicrograph nos XIX, XXI, XII, XIII, XIV, XXV, XVI shows pyrrhotite, Arsenopyrite, Chalcopyrite and pyrite. Quartz grains and ilmentite have been intruded along the boundaries of pyrrhotite and Arsenopyrite which may have come at later stage stage of crystallisation. The association of arsenic and bismuth is reported from a-plethora of hydrothermal deposits all around the world. Experimental work shows that the solubility of gold in hydrothermal solutions increases with the concentration of arsenic. Bismuth and arsenic are homologs having similiar property and structure and commonly occur together in sulphide phases such as arsenopyrite and can be positively correlated with gold. Gold is associated with Arsenopyrite as observed in analysis. In photomicrograph no. XXVII, there is association of Zircon, Monazite,Thorium and Xenotime of REE phases. Small grains of monazite and bismuth are also present in samples. REE represents incompatible phases which are concentrated in rocks formed during later episodes of magmatic crystallization or early episodes of partial melting. As the mineralizaiton in chakariya block is of hydrothermal type therefor it may have formed during later episode of magmatic crystallization. photomicrograph no. XIX, XXI shows the presence of arsenopyrite phases with few grains of Bismuth. Native bismuth are also present in arsenopyrite. Photomicrograph no.- XXIII shows association of Ilmentite, Zircon,Tungston,Yittrium, and Thorium in pyrrhotite, chalpyrite, pyrite and arsenopyrite phases. There is presence of arsenpyrite and pyrrhotite phases which is showing distinctive boundaries. REE phases are mostly present along the fracture planes which may have come as later stage of crystallization. Statistical analysis of core and bed rock samples in chakariya block also supports the corollary of Bi-As-Au association. Photomicrograph no. XXII,XXIII shows corona strucure with pyrrhotite rimmed by pyrite which is formed as an alteration product of pyrrhotite, also occuring along the margins and fracture within pyrrhotite. It also shows the partial or completely replacement of pyrrhotite by pyrite Most of the suphide phases observed during the EPMA studies are anhedral having irregular and blurr margins suggesting rapid cooling of hydrothermal solution and subsequent haphazard growth of suphide phases during cooling.

In chakariya block Au occurs as altered form of arsenopyrite called scorodite and along secondary foliaton of phyllite and primary foliations (banding) of BIF. The source of gold in phyllite and BIF is also a result of perculation of hydrothermal emanations along foliation planes ( whether primary or secondary) of these rocks. In Chakariya block greenish phyllite and

QVG contains arsenopyrite, pyrrhotite, chalcopyrite, pyrite, scorodite mineral grains. These grains preserve chemical information adopted during their formation and subsequent alteration.

V.02.4: Structure:

Primary Planar Structures: These are represented by the compositional and colour banding preserved in the banded iron formation. It is denoted by alternating silica (chert) and ferruginous bands. Chert band is regarded as S0. The trend of S0 is WNW-ESE in the limbs.

Secondary Planar Structures:

The secondary planar structures include foliation such as mineral schistosity. S0 and S1 are parallel in the limbs and cross-cutting in the hinge portion.

(A) Foliation: The most important secondary structural element is Foliation (S1). It is due to orientation of flaky minerals. The foliation is parallel to bedding in limbs of folds. The second set of Foliation (F2) is at an acute angle to S1. Based on their relative interrelationship, these are termed as S1, S2 etc.

JOINTS: The rocks of the mapped area are highly jointed. Some of the joints appear to have been developed due to shearing or faulting and can be designated as master joints along WNW- ESE direction. The following trends are recorded in the Chakariya Block:

(a) N-S/80° dip due east or west

(b) NE-SW/moderate to high dip towards both sides

(d) ENE-WSW/High dip towards south-east.

The rocks of Mahakoshal Group have suffered at least three phases of deformation. First deformation resulted in very tight isoclinal fold (F1) with development of schistosity (S1) which is parallel to S1. The second phase has evolved (F2) folds, which are marked by wide spaced schistosity (S2) making an acute angle with S1. The youngest deformation is (F3) which is represented by open folds of all scale with axis in N-S or NNE-SSW direction. (after Srivastava et.al, FS: 1994-96)

V.02.5: Metamorphism Mahakoshal Group of rocks exhibit greenschist facies metamorphism indicated by presence of chlorite, muscovite, sericite  quartz feldspar  epidote and calcite minerals. V.02.6: Mineralogy of the Mineralized zones and ore textures. To understand the mineralogy of the ore zone and texture, Bed Rock Samples, EPMA, SEM- EDX samples were collected during the course of field work. The samples were also sent to 26

respective chemical division. The important ore zone and texture can be distinguished in these lithologies after the microscopic study. Quartz vein grey and Quartz vein mixed: Quartz veins are present in Chakariya which are of various dimension and colours. The quartz veins are generally aligned parallel to the regional foliation direction i.e. WNW-ESE but it is also noticed that few small quartz veins cut across this direction. Quartz veins are mainly confined into southern part of the block. Gold bearing quartz veins are parallel to metapelites (Phyllite) and are epigenetic in nature. Development of quartz, sericite, and chlorite alteration minerals in the quartz veins confirms that silicification, sericitization, and chlorization processes are associated with gold mineralization. The results of gold bearing quartz veins analysed with AAS are shown in (Annexure-VII). The concentration of gold varies from 0.72 to 9.16 ppm. This signifies that the quartz veins are mineralized with gold. The concentration of Gold in 07 bed rock samples is ranging from 2.06 ppm to 9.16 ppm. The encouraging results are also from the samples of Scorodite. Secondary alteration of the arsenopyrite has given rise to a powdery arsenate termed scorodite (Jha et.al 2000). Specks of arsenopyrite were observed during sampling, therefore it can be inferred that gold and As bearing minerals (Arsenopyrite+Pyrite) correlate positively, and may have played an important role in the concentration of Au in hydrothermal system.

V.02.7: Pitting and Trenching.

A total of 50 cubic metres trenching has been carried out in Chakariya Block in 04 trenches. The length of trenches varies from 07.00 to 27.00 metres. The trenches were cut across the mineralised zones. Each trench was of 1 meter width and 1 meter depth. The location of trench has been estimated from the prepared cross-section of boreholes to observe the continuity of mineralized zone on the surface with respect to the suspected mineralized zone. Channel sampling was carried out for the collection of samples from the trenches. Channels were cut horizontally in the lower portion of the walls of the trenches. The width of channel was about 5cm and the depth was around 3 to 5cm, and chips, dust etc were collected together to form sample. The sample length was one metre depending upon mineralisation.

The analytical results of Bed Rock Samples has shown encouraging results. Values of Au in samples of Scorodite band ranges from 1.26ppm to 9.16ppm. Scorodite bands are good pathfinder for gold mineralization worldwide, in Chakariya block also has shown promising Au values whereas Quartz vein grey shows values 0.72ppm to 2.39ppm. This signifies that the quartz veins are also mineralized with gold in this region. The descriptive statistical analysis and Correlation matrix is given in Annexure- VI.

V.02.9.2: Discussion of results Petrochemical samples

Petrochemical analysis has been carried out by pressed pallet method. The bulk-rock chemical data for metasediments of Dudhmania Formation (06 nos. of phyllite and 04 nos. of samples from Scorodite band) is shown in annexure-XII(A). The Al2O3 content in samples range from 0.76 to 27.99 with mean of 12.94 and median of 15.78. The standard deviation is 3.44 %. In samples alumina shows negative skewness (0.09) and kurtosis is -1.99. The Fe2O3 content in samples ranges from 4.7 to 28.24 (range 23.54) with mean of 15.42 and median of 14.91. The standard deviation is 9.74. In samples iron shows positive skewness (0.1) and kurtosis is -

2.24.TiO2 content in samples ranges from 0.05 to 0.07 with mean of 0.38 and median of 0.47.

The standard deviation is 0.08. In samples TiO2 shows positive skewness (-0.27) and kurtosis is - 2.01. The CaO content in samples range from 0.15 % to 1.65 % with mean of 0.44 % and median of 0.15%. The standard deviation is 0.49%. In samples calcium show positive skewness (2.01) and kurtosis is 3.94. The MgO content in samples range from 1.40 to 7.32 with mean of 3.86 and median of 2.05. The standard deviation is 2.63. In samples magnesium shows positive Skewness 33

(0.48) and kurtosis is -2.19. Manganese is relatively abundant with an average upper crustal abundance of 600 mg kg-1 and a bulk continental crust average of 1400 mg kg-1 (McLennan and Taylor 1999) of the transition metals, only Fe occurs at higher concentrations in the Earth‟s crust. The MnO content in samples varies from 0.02 to 0.22 with mean of 0.02 and median of 0.06. The standard deviation is 0.02. In samples MnO shows positive skewness (+1.05) and kurtosis is 0.42. The Na2O content in samples ranges from 0.03 to 0.75 with mean of 0.16 and median of 0.10. The standard deviation is 0.22. In samples Na2O shows positive skewness (2.39) and kurtosis is 6.43. The K2O content in samples range from 0.03 to 8.60 with mean of 3.18 and median of 1.89. The standard deviation is 3.39. In samples K2O show positive skewness (0.45) and kurtosis is -1.74. Phosphorus is the eleventh most abundant element in the Earth‟s crust, constituting approximately 0.1% by weight. The P2O5 content in samples varies from 0.04% to 0.33% with mean of 0.14% and median of 0.12%. The standard deviation is 0.09%. In samples

P2O5 shows positive skewness (1.35) and kurtosis is 1.60. Barium is a lithophile element and is the 14th commonest element in the Earth‟s crust. In sedimentary rocks the concentration of Ba is related to the abundance of K-feldspar, clay minerals and hydrous Fe and Mn oxides, on to which the element may be adsorbed (Wedepohl, 1978). The Barium content in samples ranges from 119 to 2408 with mean of 658 and median of 513. The standard deviation is 698. In samples Barium shows skewness (1.95) and kurtosis is 4.54. High values of barium 2408mg/kg has been observed in one sample of phyllite. High values of barium may have come as substitution for potassium in alkali feldspar present in phyllite. Analytical results of Scorodite band samples shows less amount of SiO2 and relatively high Fe2O3 content as its common hydrated iron arsenate mineral. The crustal abundance of Nb is estimated to be 20 mg kg-1 (Wedepohl, 1978,). The Niobium content in samples ranges from 5 % to 46% with mean of 25.36 % and median of 23 %. The standard deviation is 8.76%. In samples Niobium shows skewness (0.41) and kurtosis is (-0.83) with modal class of 17 %. Chemical Discrimination Diagrams for rocks of Dudhmania Formation The rocks of Dudhmania Formation belongs to Mahakoshal Group of rocks. These rocks are metasedimentary in nature. Therefore chemical behaviour has been attempted to have a basic idea of the source resulted in the accumulation of these sediments. Since Major and trace elements can be subject to important mobilization and fractionation during weathering, mineral accumulation, diagenesis and metamorphism.

Figure-V: Log Na2O/K2O vs. Log SiO2/Al2O3 binary geochemical classification diagram for Phyllite of Chakariya Block {after Pettijohn et al., 1972 (indicated by dashed lines); modified and boundaries redrawn by Heron, 1988 (indicated by solid lines)

The analysed samples have lower alkali vs. silica ratio (Log SiO2/Al2O3= 0.26 to 1.19). Log

K2O/Na2O ratios are also variable, ranging from -1.6 to 0. Thus in the Pettijohn et al., (1972) diagram based on of log (Na2O/K2O) vs. log (SiO2/Al2O3) content the Dudhmania Formation of Mahakoshal Group of sediments can be classified as arkose and lithic arenite with only three samples are classified as lithic arenite and seven as arkose. (Figure-V). The high content of Na2O and K2O appears to be due to the predominance of albite and K-feldspars in the sediments. The samples collected from scorodite bands falls in lithic arenite zone whereas the phyllitic samples classifying as arkose.

Metasedimentary samples under study are classified as quartz rich with K2O/Na2O>1. The quartz rich samples suggest the passive margin settings of their deposition. A total of 10 samples belongs to passive margin zone in K2O vs. SiO2. The passive margin (PM) settings suggest the mineralogically mature (quartz rich) sediments deposited in plate interiors at stable

continental margins or intracratonic basins (equivalent to the „trailing-edge tectonic settings of Marynard et al., 1982; Kepp et al., 1983).

Figure-VIII: The logarithms plot of the weight ratios of SiO2/Al2O3 against (Na2O+CaO)/K2O for Dudhmania Formation of Mahakoshal Group of rocks representing the chemical behaviour of the samples (Garrels and Mackenzie, 1969).

The weight ratios of SiO2/Al2O3 against (Na2O+CaO)/K2O show positive correlation and suggest the greywacke and argillaceous source for the deposition of rocks of Dudhmania formation.

V.02.10: Details of interpreted Mineralized zones on the basis of geological investigation.

The mineralized zones have been observed during geological investigation. Trench no. CTR-02 shows scorodite band. Thus trench assists in delineating the surface configuration and grade of mineralized zone. Both scorodite and quartz veins form important mineralised zone/marker horizon. Scorodite is restricted to the south of BIF bands.

VI. INTEGRATION OF GEOLOGICAL, GEOCHEMICAL AND GEOPHYSICAL EXPLORATION DATA AND INTERPRETATION THERE OFF:

I. Creation of Geophysical, Geochemical, Geological (Lithological, and structural and outcrop maps on true scales.)

GEOCHEMICAL EXPLORATION: Geochemical exploration work has not been carried out in the block area. Only the geochemical mapping has been carried out in 63L/11 during the FS: 2015-16. The Chakariya block falls in C-3 Quadrant of toposheet no. 63L/11. In NGCM program, composite samples are prepared by mixing and homogenizing of four adjacent unit cell samples. The stream sediments samples from the composite no. 024 and 025 have been prepared. Analytical data of the composite sample nos 24 and 25 with other adjacent areas has been studied for Packages A and H. Results of Gold has not been received so far (Bage et. al 2016), hence no conclusion could be drawn from the NGCM data. Though Water sample was collected from the C-3 (Chakariya Nala) Quadrant during FS 2015-16, Au and As has been reported <0.001 and 193 ppb respectively (Bage et. al 2016), which doesn‟t show any significant value. The results of ICP-MS (Package) and XRF (Package A) are given in Annexure- XI

VII. ABIOTIC PARAMETERS: Soil, Surface water (Pre-Monsoon and Post-Monsoon Ground water sampling.)

Ground water sampling: A total of 05 water samples have been collected from the dug wells and Handpump of Chakariya Block. Soil Condition: Soil is brownish yellow in color and lacks humus. It is also dry and low in nutrient content and requires moisture and fertilizers to support agriculture. Soil profile is shallow and not well developed.

Field Photograph-VIII: Collection and in-situ measurement of water sample from dug well at Chakariya block.

Analytical results and its interpretation: The water of Chakariya Block is more or less neutral in nature with pH ranging from 6.70 to 7.44 with a mean value of 7.16. This implies that, the general water quality of the region including dugwells is alkaline nature. Total dissolved solids (TDS) of groundwater and surface water ranges from 205 to 247 mg/l. The TDS is well within

range of drinking as well as agricultural purposes. Concentrations of Na, K, Ca and Mg varies from 23.7 to 44.6 mg/l (mean 33.76 mg/l), 0.4 to 1.8 mg/l (mean 0.76 mg/l), 14 to 22 m/l (mean 17.2 mg/l) and 4 to 18 mg/l (average 8.2 mg/l), respectively in groundwater/Dugwell and Surface water. Concentrations of Cl, NO3 and HCO3 ranges from 0 to 84 (ave. 16.8 mg/l), 15.6 to 34.54 (ave. 6.90 mg/l) and 183 to 843 (average, 169 mg/l), respectively, observed in the water samples.

SO4 concentrations vary from 09 to 40 mg/l (ave. 8 mg/l). Field data sheet, Water analytical data, is enclosed in Annexure – I (A), I (B) and I (D). The correlation matrix of Mn, Fe, Co, Zn and As has been calculated. Mn shows very strongly correlation with Co and strongly correlation with Fe and Zn. As shows negative correlation with Mn, Fe, Co and Zn. Fe shows very strong correlation with Co and fairly strong correlation with Zn. The descriptive statistics and correlation matrix of water samples is shown in Annexure-I (E), I (F)

VIII: MINERAL DEPOSIT:

VIII.01: Surface indication of mineralization:

Mineralization in Chakariya Block is mainly concentrated in Quartz vein Grey and Scorodite bands. Mineralization is also observed in Phyllite and BIF at places. Quartz vein Grey is the most probable source of mineralization from which minerals have also disseminated to other country rocks as well.

Scorodite is an altered mineral product resulting from the oxidation of arsenopyrite and other arsenic bearing minerals and arsenic is usually closely associated with gold therefore scorodite can be used as a pathfinder mineral for gold mineralization. Scorodite is manifested on the surface in the form of discontinuous bands trending WNW-ESE and was observed at many places in the field including NE of Borehole GCD-07, near Trench CT-9, North of Boreholes GCD-01 and GCD-04.

Field Photograph-X: Small Scorodite body in the west of Trench CTR4 Longitude: 82°43´30.7´´ Latitude: 24°17´10.16´´

VIII.02: Mode of occurrence The mode of occurrence refers to the pattern of distribution of ore minerals in a host rock. The occurrence of gold mineralization is well known in Mahakoshal Greenstone Belt. Hence on a regional scale the stratigraphic control is discernible by the occurrence of gold mineralisation in volcano-sedimentary rocks of Mahakoshal Group. Occurrence of Gold mineralization in this area is restricted to Quartz vein, Greenish Phyllite and Scorodite bands and to a lesser extent in BIFs.

White quartz veins/Grey quartz veins/Mixed quartz veins are intruded into phyllite along S1 foliation planes. These quartz veins are containing specks and stringers of sphalerite, pyrite, chalcopyrite, arsenopyrite and mineralization occur in the form of vug filling. The placement of

quartz veins along the foliation planes and its further fracturing and folding at places is suggestive of structural control on the occurrence of mineralization.

Field Photograph-XI: Folding observed in quartz vein at Chakariya nala. Longitude: 82°43´7.5´´ Latitude: 24°16´39.2´´

Gold mineralisation in block occurs in different modes which are as under- 1. Within arsenopyrite rich layers, 2. Within post F1 quartz veins, 3. Within syn to post F2 quartz veins, quartz -sulphide veins

Gold bearing quartz and quartz-sulphide veins related to syn to post F2 deformation is emplaced with in F1 quartz veins VIII.03: Nature of Mineralization

Arsenopyrite (including its altered form scorodite), pyrite, chalcopyrite and galena are the principal sulphide minerals observed in the mineralized zones in the surface and in drill cores. The characteristics of the ore minerals are as follows: Arsenopyrite: Arsenopyrite is most dominant sulphide phase occurring with other sulphides. It occurs as euhedral to subhedral crystals with characteristic rhombic to angular shapes. At places it occurs as fine grained well developed crystals aggregate. Arsenopyrite grains size is ranging from few mm to approximately up to 1 cm. The colour of arsenopyrite is dull grey and gives black to steel grey colour of streak. On the surface it has altered to limonite and Scorodite whereas in core samples it shows perfect crystals surrounded by matrix of arsenopyrite and pyrite with altered scorodite at the border. In few samples arsenopyrite grains are fractured and this fracturing may be attributed to a later deformational event.

Chalcopyrite: It is a brass yellow coloured mineral having a dark grey streak with greenish tinge. It occurs as inclusions in fine grained pyrite as well as isolated grains associated with arsenopyrite and pyrite. It is present in the form of subhedral to anhedral grains in the quartz veins and along phyllitic foliations.

Pyrite: Pyrite has also been observed in core samples. It generally occurs as euhedral fine grains. Chakariya block exhibits the following setup for gold mineralisation: A. Epigenetic type: Vein type deposits in phyllites and scorodite bands. B. Syngenetic Stratabound type: Bedded type associated with Banded Iron Formations

Vein Type Mineralisation:

Fold axes largely control the emplacement of auriferous quartz veins with or without sulphide mineralisation. The vein type gold mineralisation appears to have been formed during the deformation and low-grade metamorphism. Quartz vein are co-axial with the phyllite though at places it cuts across the phyllite. Among various quartz veins sampled, one sample from Chakariya

block has reported Au value of 8.8 ppm. This confirms that Chakariya prospect has epigenetic auriferous quartz veins.

Bedded Type Mineralisation:

The gold mineralisation is present within the thin stretched cherty bands of BIFs and the dominant sulphides are arsenopyrite and pyrite.

VIII.04: Details of Mineralized zones: Strike length and Width of another identified on the basis of geology, Geophysical and Geochemical exploration

Scorodite occurs near the contact of phyllites and BIF as linear, detached bands parallel to the regional trend of rocks. Perhaps this is a zone between competent layer (BIF) and an incompetent layer (phyllites) and such zones are good loci for gold mineralisation. It has more or less uniform thickness of about 2 metres and has a strike length of 800 metres. Its trend is WNW-ESE. VIII.05: Alterations zones and its relevance with mineralization.

Mahakoshal Group of rocks has undergone wall rock alteration at certain places and such places are important for gold mineralisation.

Field Photograph-XII: Sulphidation of Scorodite north of Borehole GCD-01, Longitude: 82°43´28.3´´ Latitude: 24°17´11.3´´ Sulphidation: Ferromagnesian silicates react with sulphur and arsenic to form sulphides. Minerals such as arsenopyrite and pyrite of the Chakariya block may have formed due to this process. The studies of wall rock alteration are important as they provide exploration targets and contain high values of metals as compared to the host rock.

Chloritisation: It is always associated with sericite and/or biotite. The Fe-Mg silicates of the phyllites break down to develop chlorite.

VIII.06: Genesis of Mineralization/Genetic model of Mineralization

The deposit type of Chakariya Block is turbidite hosted type (Devrajan et.al 2006). Key manifestation of deposits is by concentration of gold-bearing veins by secondary features which has led to the deposition of sulphide mineralization in quartz vein grey. In Chakariya block it is being carried along with the greenish phyllite along the foliation plane (Jha et al). The gold mineralization is epigenetic in character with presence of gold with the arsenopyrite and scorodite (based on BRS results). On the basis of core study it has been observed that emplacement of silica rich melt along foliation plane S1 and formation of quartz vein with

subsequent precipitation of sulphide minerals in the form of vugs filling, pecks and stringers. Deformation of quartz vein initiated the second stage of mineralisation. Along the deformation planes the hydrothermal fluids circulated and subsequent precipitation of sulphide mineralization along with silicate phases viz chlorite. Later stage of mineralization is manifested by precipitation of sulphide minerals along the fracture planes which are cross cutting the foliation plane. Gold bearing quartz veins indicates epigenetic nature of mineralization.

IX.: EXPLORATION BY DRILLING

IX.01: Stages of exploration as per mineral content rule: The UNFC consists of a three dimensional system with the following three axes: Geological Assessment, Feasibility Assessment and Economic viability. The process of geological assessment is carried out stage wise. The typical successive stages of geological investigation i.e. reconnaissance, prospecting, general exploration and detailed exploration, generate resource data with a clearly defined degrees of geological assurance. These four stages are therefore used as geological assessment categories in the classification. The four stages of geological assessment are represented by 4 codes i.e. 1 (detailed exploration), 2 (general exploration), 3 (prospecting) and 4 (reconnaissance). As per UNFC classification, this exploration can be classified as G-2 stage as drilling is being carried out for augmentation of reserve in between previous boreholes and 2nd level planning for the earlier drilled boreholes.

IX.02: Methodology of drilling with the details of type of drilling i.e. core drilling auger, reverse circulation etc. In Chakariya Block, District-Singrauli (MP) diamond core drilling was used for drilling. The drill bit used here is composed of group of small, industrial grade diamonds set into a metallic, soft matrix. As the ground is drilled, the matrix will wear away and expose more diamonds. This is then attached to a drill rod, which is around 10 feet in length, and then more sections of pipe can be attached to the top of this so a greater depth can be drilled. Inside the drill rod, a core tube is attached to a cable via a latching mechanism. The core tube is lifted to the surface using the cable, so the solid core can be removed. There are two primary types of diamond drilling-rotary drilling and wireline drilling. Drilling work for Chakariya block was outsourced to Gemko-Kati. Core drilling (NX size) was carried out by KDR-750 machine using wireline drilling method.

IX.03: Borehole planning: Spacing of Boreholes and level of intersection of Mineralized zones as per mineral content rule. This project is continuation of FS 1999-2001, in which a total of 09 boreholes with an interval of 100m has been drilled. Nine boreholes with total of 1291.30 metres were drilled. The inclined

boreholes with 50° angle were planned to intersect the mineralised zones at about 60m vertical depths. During FS 2016-17, a total 07nos of borehole has been planned and executed in Chakariya Block. As per the suggestion from The Dy. Director General, Regional Mission Head (M-II), Geological survey of India, Central Region, Nagpur vide letter no. 202/RMH/CR/2016 dated 19- 08-2017, Two boreholes of 50m vertical interval has been planned in between GCD04 & GCD01 and GCD05 & GCD03 to confirm the trench values and also to check the strike continuity of mineralized zone. The second boreholes of 100m vertical intersection has been planned for GCD-01, 05, 06, 07 and 08 to examine the depth continuity of mineralized zone intersected in first level (50m). The cross-section of boreholes and location on detailed geological map is shown in Figure-IX, Figure-X, Figure- XI, Figure-XII, Figure-XIII, Figure-XIV Figure-XV and Figure-XVI. Borehole points along with RL at collar and fixing of alignment pegs for the rigs was carried out by Total Station.

IX.07: Mineralogy of ore zone The gold mineralisation is mainly associated with „scorodite‟ and „grey quartz vein‟. Secondary alteration of arsenopyrite has given rise to a powdery arsenate known as „scorodite‟. Scorodite band extends nearly for 800 metres as detached bodies. Both these rocks have high incidence of gold occurrences on surface as seen in trench samples and in the subsurface as seen in drill cores. Minor mineralization is present in BIF and phyllite. Mineralization is both of epigenetic and syngenetic nature. Epigenetic mineralization is present in the form of Vein type deposits in phyllites and scorodite bands while syngenetic mineralization is concentrated within chert bands of BIFs. Mineralization is also present in micro-fractures in the rocks.

The above figure shows the concentration of arsenopyrite, scorodite and chalcopyrite in arenaceous phyllite and arenite. These minerals have been associated with the grey quartz vein in the core samples. The nature of intrusion of quartz vein in areanaceous phyllite suggests its epigenetic nature. The vein type mineralization which has been intruded along the foliation and across the foliation as vein and stringers, which suggests mineralization in chakariya block is epigenetic mineralization in nature in the form of vein type deposits. Small isolated outcrop of scorodite has been observed near trench CT-09. At surface there is indication of limonite, oxidation adjacent to greenish coloured hard compact chert band at the contact of phyllite bands (Field Photograph – XIII and Field Photograph –XIV). At location N24°17´4.7´´ E 82°43´39.8´´ fine lamination of silica sandwithched between iron rich layers, some of the silica/chert layers are forming boudins and shows stretching along the foliation. Direction of foliation is N65°W.

IX.08: Borehole deviation test and methodology Deflection of borehole from its intended course is termed as Bore-hole deviation. It can be of two types: 1. Azimuthal deviation or horizontal deviation 2. Zenithal deviation or vertical deviation Borehole deviation test has been carried out for each drilled borehole, with an aim to decipher the angle which has been deviated from its normal course. Usually "Starting error" is caused by setup error, some by drill platform instability and some by drill rod instability at the start of the hole. We may not be able to control the accuracy of all the steps, but we can determine

105

where the hole has gone. For every 100 meters of drilling, a 2º error will cause 3.5 meters of offset (3.5 feet/100 feet), which may or may not be within acceptable error. The rocks through which the hole is drilled can influence the direction. Check points: In deep borehole the azimuth deviation may be as large as 50m. Few borehole reappear on the ground by deviation. When the angle of borehole is large the hole tends to be perpendicular to it. High angle borehole have the general tendency to go upward due to pressure of drilling rod behind the core bit whereas small angle borehole has the tendency to become parallel to bedding and schistocity. Cause for Borehole Deviation: Alternate hard and soft formation, Presence of boulder bed, Cavity, shears etc. Low angle borehole and presence of planer surface. Improper anchoring i.e. leveling of drilling machine. Crooked and short drilling rods and loose coupling, Unequal pressure applied, Vibration due to machine. Etch Method or HF method was used for Borehole deviation. Etch method is a method of measuring borehole deviation. This method use Hydrofluoric acid (HF). It has the tendency to make mark on test tube when kept at least 3-4 hours. Procedure: Test tube has been half filled with HF (Hydrofluoric acid), and housed in short barrel. The apparatus has been lowered at desired depth i.e. at an interval of 30 mts each. The test tube has been kept in the borehole for at least 3-4 hours. Result: HF itches out elliptical mark on the tube measuring the horizontal depth at a position. Inclination of the tube has been determined. HF marks on the test tube. The etched marked meniscus has been used to estimate etched angle. A meniscus correction for capillary action of HF is advisable to measure the angle. The estimated etched angle is correlated with the True angle and the deviation is established. The borehole deviation chart is shown in Figure-XXVII. The borehole deviation data are provided in Annexure-X. Disadvantage: Azimuthal deviation couldn‟t be measured. The deviation test for each borehole has been carried out at field, during the drilling at an interval of 25m or 30m each. It has been inferred that the there is offset of 2° to 3° after the 100m and 150mts respectively..

IX.09: Methodology of ore zone sampling.

The Mineralized zones samples have been marked along the boreholes. The interval of Sampling is 25cm, 30cm and 50cm. The zones which are less than 25cm have been neglected for the sampling purposes. During the ore zone sampling Quartz vein Grey, Scorodite, specks of arsenopyrite, pyrite has been given more emphasis as gold mineralization in Chakariya block is associated with the sulphide zones. The numbering of samples has been initiated from Borehole no. CBH-01 to CBH-07. The Sampling has been carried out to ascertain the grade and metal value that vary in proportion form one another. It has been noted that single sample taken from one part of the orebody generally doesn‟t provide a representative picture of the grade of the entire ore body. So a large no of well spaced samples are required for ascertaining the average grade with an acceptable amount of ore body. The sampling also reveals the pattern of mineralisation within the ore richer and leaner ore portions. Therefore after examination of the core, the sampling zone has been fixed. As per the FSP a total of 100 samples have been marked. The details of Samples and their interval are as follows.

IX.10: Sample preparation, Chemical analysis and laboratory procedures. Methodology of sample preparation: Core Samples: The sampling procedure is a very important aspect of G-2 items. Any small error in the sampling methodology may lead to erroneous result and wrong interpretation. Due to the significantly increased performance of analytical methods especially in terms of sensitivity, precision and accuracy, the most dominant source of error is sampling. For this reason conventional sampling procedures should be strictly followed to avoid contamination during sampling. Drilled cores were cut into four half by core splitter/core cutter. Two half was used for the preparation of Core samples. The core samples were crushed completely and powdered upto -120 mesh. Sieved through -120 mesh using standard sieve of ASTM standard. After homogenization and coning and quartering. Coning and Quartering:

The samples were packed in tight polythene bags with properly numbered. The Samples were divided into two equal parts. One part was stored as the original sample and the other part was submitted to respective geochemical division for geochemical analysis. Third parts of the core-samples were prepared as chip samples for the Beneficiation study. Fourth part of the samples is kept within the core-boxes and submitted to office.

IX.11: Check samples: At least 10% of samples may be analysed from third party NABL accredited or other accredited labs. The samples have been submitted to Director, Geochemical laboratory, SU: MP, Bhopal for the analysis from third party NABL accredited or other accredited labs.

IX.12: Details of intersected Mineralized zones of the boreholes drilled and their correlation. Chakariya Block having a length of about 705 metres was taken up for exploration during FS 2016-17. A total of 07 boreholes with 855 metres were drilled. The inclined boreholes with 50° angle were planned to intersect the mineralised zones. Two boreholes of 50m vertical intersection were planned in between GCD-04 & GCD-01 and GCD-05 & GCD-03 to confirm trench values and also to check the strike continuity of mineralized zones intersected in GCD-01 and GCD-05. The distance between CBH01 and CBH02 which are 1st level borehole of 50m vertical intersection are 200mts apart from each other. Details of mineralized zones (based on visual estimation) have been given in Table-XXXII, Table-XXXIII, Table-XXXIV, Table-XXXV, Table-XXXVI, Table-XXXVII and Table- XXXVIII. The mineralisation observed in drillholes (from CBH-01 to CBH-07) is described as following: Drillhole No. CBH-01: This drillhole was planned 50 west GCD-01 to confirm trench values and also to check the strike continuity of mineralized zones intersected in GCD-01. The BRS samples had recorded higher values of gold in scorodite.

X. ORE BENEFICIATION STUDIES: BENEFICIATION STUDY REQUIRES MINIMUM 250KG OF SAMPLE WHICH CAN BE PREPARED FROM THE REMAINING POWDERED SAMPLES OF MINERALIZED ZONES AFTER SUBMISSION OF SAMPLES FOR CHEMICAL ANALYSIS.

The mineralized zone has been marked during the preparation of core samples. The 1/4th part of the core samples has been prepared as chips samples of (atleast 1 inch) after the remaining powdered samples of mineralized zone (i.e 1/2th Part) and core samples for repository (1/3th part) samples have been submitted to Indian Bureau of Mines, mineral processing unit, Hingna Road Nagpur for the ore beneficiation studies.

XI. GEOTECHNICAL STUDIES ON BOREHOLE CORE SAMPLES OF MINERALIZED ZONE HANGING WALL AND FOOTWALL SIDE.

1. Porosity 2. Moisture content, water absorption 3. Bulk density Tonnage factor or Bulk density is a multiplier to the volume for determination of ore. Bulk density is determined for large volume in which opening of rocks ( joints fracture, brecciation,) are included. Determination of bulk density using drill core: Volume= ½ x π r2l, Sp. Gravity = W/V= Bulk Density W= Weight of Sample. Result: Bulk density < Actual Density 4. Uniaxial Compressive strength 5. Uniaxial Tensile Strength 6. Triaxial Strength 7. Young‟s Modulus 8. Poission Ratio 9.RQD (Rock Quality Designation Study): RQD is an improved method of logging rock core to calculate a modified core recovery percentage. It is measurement of the percentage of “good” rock in the rock core run (intact pieces 10cm or more in length). RQD did not replace the traditional core recovery percentage; both have been reported for each core run. RQD% = (Length of Core pieces greater or equal than 10cm / Total length (m) Core run) X 100. The minimum standards for RQD are have been accounted during the logging. HQ size core, Drilled with double-tube core barrel, Count only pieces of core that are greater or equal to 10cm

XII. RESOURCE ESTIMATION:

XII.01: Introduction.

The main aim of the geological survey is to size up rock, minerals, etc. This sizing up of the ore body is known as resource estimation, which tells about the quantity, quality and amenability to commercial exploration of raw material. Resource estimation is a very important phase in development of a mine, after all prospecting and exploration need estimation of ore. So as to calculate economic viability of the resource a precise and accurate estimate of resource is needed to make future plans. A total of 198350 tonnes of ore with an average grade of 1.20g/t with average width of 1.26 metres has been estimated for both trench and drillholes (Jha et al 1999-2001). As current works is based on augmentation of ore reserve, a part of Chakariya block is utilised here for drilling with close intervals and resource estimation. LV section and cross sections for resource estimation has been prepared and resource estimation is done based on chemical data of core samples.

XII.02: Detailed Description of Mineralized zones

Depth of intersection of ore horizon is given in Table-XXXII, Table-XXXIII, Table-XXXIV, Table-XXXV, Table-XXXVI, Table-XXXVII and Table-XXXVIII.

XII.03: Core Recovery Core-Recovery is an important factor in computation of ore reserves, there the core recovery should be very high at least in mineralized zone. Core recovery has been measured length wise. The detailed core recovery is shown in Table-XVII, Table-XVIII, Table-XIX, Table- XX, Table-XXI, Table-XXII and Table-XXIII. Core Recovery= (Lr/L) x100 Lr= Recovered Core L=Run length. In Chakariya the core recovery is more than 95% there reserve calculation purposes it has been considered 100%. However it totally depends upon the nature of deposits and its occurrence. If the core recovery is less than 95% the correction factor have to be applied during the calculation of thickness of lode. Mainly there are three options. Dilution method: the Assay value of recovered core is distributed in the whole run assuming that the part of core which is not recovered is barren.

132

Usually the grade goes down in this method.

Gr= A*x L1/L, where Gr= Grade, A= Assay value of sample. Reduction width method: In this case the core loss is considered as voids and lode width is taken as the length of the core recovered, thus the thickness may be reduced but grade remains as per assay values. Equal grade Method: This method is adopted where the core recovery is more than 90% and less than 95%. In this method the grade of recovered length is taken as grade of run with the assumption that the uncovered portion also contains the same assay value. XII.04: Cut off Grade consideration Cut off are of two types. 1. Threshold cut-off: it is the cut off that is fixed by Indian Bureau of Mines. i.e. the Grade below which we cannot mine the ore economically Ct= Pcx100/Vm, Ct= Cut off Grade, Pc= Production cost, Vm= Value of mineral deposit. 2. Operational Cut off: The operational cutoff are the values which is determined by Geologist, Statistically the cut off grade of deposits will be determined by preparing histogram of all analyzed samples because the result of (MZ) or samples are different therefore we average or calculate one operational cut off. 3. The cut off grade used for marking gold mineralized zones in Chakariya block is 0.5 ppm. XII.05: Minimum stoping width consideration The minimum stoping width of orebody to be dug out, this is usually 2.0m for underground mining method. For delineating mineralized zones in Chakariya block the consideration of minimum stoping width has been ignored. XII.06: Correlation of ore lodes. The mineralization in Chakariya block exhibits vein system. It may have come along with quartz vein by secondary mobilization, therefore the mineralized zones are not continuous. The mineralization is exposed at different level in different boreholes. Cross section has been prepared and the correlation of mineralized zone are shown in Plate-III

XII.07: Description of Lodes. Details of expected mineralized zones has been given in Table-XXXII, Table-XXXIII, Table- XXXIV, Table-XXXV, Table-XXXVI, Table-XXXVIII, Table-XXXVIII

XII.08: Preparation of LV section LV section for Chakariya block is prepared and shown in Plate-IV.

133

XII.09: Assumptions of resource estimation Mineralized zones in bore holes are intersected at different levels (two borehole of 50m vertical intersection and five boreholes of 2nd level of 100m vertical intersection) therefore few assumptions have been established for the resource estimation. 1. Cumulative of all mineralized zones in a borehole has been considered instead of apparent thickness of each mineralized zones in a borehole. 2. Cumulative horizontal width has been considered for each borehole. 3. Average angle of lode with core axis was considered for each borehole. 4. Area of influence of drillhole intersections: The area of influence of every mineralised zone intersection in drillhole has been assumed to extend half way i.e. 50 metres in the direction of adjacent drillhole laterally in 2nd level of borehole and 25 meters for 1st level of boreholes. In case of drillholes, the influence has been taken 25 metres for 1st level of bore holes and for 2nd levels of boreholes half the distance between (1st and 2nd levels) boreholes, both upward and downward from intersection to calculate cross sectional area. Strike length of mineralized zones has been considered on borehole spacing. Dip length for level-I boreholes is half of the vertical depth of intersection on both side of mineralized zones (Jha et.al 1999-2001), whereas dip length for level-2 boreholes has been determined considering the length of mineralized zone intersected between Level-1 and Level-2 boreholes. Horizontal width has been determined taking into consideration, the length of horizontal intersection of mineralized zones in borehole.

5. Core Recovery: In most of mineralised zones, the core recovery is above 95% therefore it has been assumed 100%. 6. Continuation of lodes between drillholes: Mineralized zones intersected in adjacent drillholes have been assumed to be continuous, though it may introduce certain degree of uncertainty in the resource estimation. 7. Resource estimation has been carried out based on visual estimation of mineralized zones as observed during the core logging. It is tentative and subjected to change after the receival of geochemical analytical results of core and trench samples. Each borehole comprises many mineralized veinlets therefore for the purpose of resource estimation, calculations has done using cumulative thickness of various mineralized veinlets.

134

8. One of the factors used in volumetric calculation LV section is “difference is RL” which is formed using horizontal projection of dip length influence of each mineralized zone. XII.11: Methodology of ore resource estimation XII.11.1: Cross-sectional Method The cross-section or Traverse section method prepared across the orebody represent the actual geologic feature in shape and quality. The preparation of cross-section is same as preparation of Geological cross-section of body. For the calculation of reserve by this method the area of influence and quality is considered on the basis of rule of nearest points. Tonnage = True measured thickness (cumulative of all veins in a borehole) x dip length x strike length x sp. Gravity.

A total of 27023 tonnes of ore with an average grade of 1.81 g/t has been estimated for drillholes from cross section method.

136

XII.11.2: Longitudinal vertical projected section Method (L-V Section Method) This method is very helpful in co-relating the ore body along the strike which is very important factor. This method is used for complex ore body. In LVS method the RL of the intersection of orebody has been projected on vertical plane parallel to the strike of the ore body and lodes have been co-related. The area determined by the LVS has been multiplied by the horizontal thickness of the ore body to know the thickness of ore body. i.e Tonnage= Horizontal width (cumulative of all veins in a borehole) x Strike length x Dip RL difference ( i.e. Difference of higher RL – Lower RL).

XIV: CONCLUSION:

The investigated area belongs to Dudhmania Formation of Mahakoshal Group of rocks, which comprises greenish phyllite, arenaceous phyllite, tuffaceous phyllite and mixed oxide- silicate facies (BIF). A total of 100 nos. core samples, 50 nos. BRS, 10 nos. EPMA, 10 nos. of SEM (EDX), PS. 20 nos. and 10 PCS samples were collected and sent to geochemical laboratories for analysis. A total of 50 cu.m of trenching has been carried out to know the surficial continuity of the mineralized zones. The trenches were cut across the mineralised zones. A total of 50nos of pitting and trenching (PTS) samples were also prepared and submitted for geochemical analysis. Regional traverses were carried out to understand structure as well as regional geological setup of area. Core Logging along with geophysical logging of each boreholes were done. 5 nos. of water samples were also collected and sent for chemical analysis. Differential Global Positioning System (DGPS) survey was carried out and demarcated borehole points along with block boundary. Drilling in Chakariya block was started on 03.03.2017 and completed on 24.04.2017. A total of 855 m of drilling were carried out by drilling of seven (07) nos. boreholes. Two boreholes of 50m vertical interval have been planned in between GCD04 & GCD01 and GCD05 & GCD03 to confirm the trench values and also to check the strike continuity of mineralized zone. The second boreholes of 100m vertical intersection has been planned for GCD-01, 05, 06, 07 and 08 to examine the depth continuity of mineralized zone intersected in first level (50m). Predominantly there are three varieties of quartz veins in the block viz. Grey to black coloured quartz veins (QVG), White coloured quartz veins (QVW) and mixed grey to white quartz veins (QVM). The QVW veins are comparatively thicker (up to 6m) while QVG and QVM have 25cmto 50cm and occur as irregular and discontinuous bands mainly within phyllites and rarely in BIFs. The vein type gold mineralisation appears to have been formed during the deformation and low-grade metamorphism. Quartz vein are co-axial with the phyllite though at places it cuts across the phyllite. Among various quartz veins sampled, one sample from Chakariya block has reported Au value of 8.8 ppm. This confirms that Chakariya prospect has epigenetic auriferous quartz veins.

White quartz veins/Grey quartz veins/Mixed quartz veins are intruded into phyllite along S1 foliation planes. These quartz veins are containing specks and stringers of sphalerite, pyrite, chalcopyrite, arsenopyrite and some mineralization occur in the form of vug filling. The

142

emplacement of quartz veins along the foliation planes and its further fracturing and folding at places is suggestive of structural control on the occurrence of mineralization. Arsenopyrite (including its altered form scorodite), pyrite, chalcopyrite and galena are the principal sulphide minerals observed in the mineralized zones in the surface and in drill cores.

The planar parallel and continuous geometry of bed and laminations in phyllite indicates stable depositional conditions. This type of geometries is typical of distal turbidite successions. Two main events of deformation have been noticed which are responsible for the regional WNW-ESE trend of the Mahakoshal rocks and the third deformation is mild in intensity and developed at high angle to the first two deformations. Gold bearing quartz veins are parallel and across to metapelites (Phyllite) indicating epigenetic style of mineralization. The concentration of Gold in 07 bed rock samples is ranging from 2.06 ppm to 9.16 ppm mostly from the samples of scorodite. Specks of arsenopyrite were observed during the course of sampling, therefore it can be inferred that Gold and Arsenic bearing minerals (Arsenopyrite+Scorodite) correlate positively, and may have played an important role in the concentration of Au in hydrothermal system. Petrochemical analysis has been carried out by pressed pellet method. High values of barium 2408mg/kg has been observed in one sample of phyllite. Anomalous value of barium may have come as substitution for potassium in alkali feldspar present in phyllite. Analytical results of scorodite band samples shows less amount of SiO2 and relatively high Fe2O3 content as its common hydrated iron arsenate mineral. The weight ratios of SiO2/Al2O3 against (Na2O+CaO)/K2O show positive correlation and suggest the greywacke and argillaceous source for the deposition of rocks of Dudhmania formation. Dudhmania Formation of Mahakoshal Group of sediments can be classified as arkose and lithic arenite. The high content of Na2O and K2O appears to be due to the predominance of albite and K-feldspars in the sediments. Metasedimentary samples under study are classified as quartz rich with K2O/Na2O>1. The quartz rich samples suggest the passive margin settings of their deposition Most mineralized core samples looks to be blebs and stringers of arsenopyrite, pyrite and chalcopyrite. Mineralization as vug filling is also seen in core samples. The sulphide minerals comprise arsenopyrite, galena, pyrite and chalcopyrite as primary sulphides and scorodite as weathering product of arsenopyrite.

143

Scorodite is manifested on the surface in the form of discontinuous bands trending WNW- ESE and was observed at many places including NE of borehole GCD-07, in trench CT-9, north of boreholes GCD-01 and GCD-04. The water of Chakariya Block is more or less neutral in nature with pH ranging from 6.70 to 7.44. The TDS is well within range of drinking as well as agricultural purposes. A total of 27023 tonnes of ore with an average grade of 1.81 g/t has been estimated for drillholes from cross section method and a total of 24334 tonnes of ore with an average grade of 1.81 g/t has been estimated for drillholes from LV section method. Cumulative resource estimation for Gold for boreholes drilled during FS 1999-2001 and FS 2016-17 at Chakariya Block is 137782.5 tonnes with an average grade of 1.32 g/t.

The Chakariya area is having dispersed settlement with kachha houses made up of mud and wood. The Chakariya village and surrounding areas are sparsely populated with population of no more than 250 people. The topography is undulating with small 3 Infrastructure & Environment hills and shallow valleys often occupied by seasonal nalas . It is a dry and arid region supporting dry deciduous vegetation and shrubs. Forest is managed by the community itself. Agriculture is monsoon dependent and soil profile is shallow and not well developed. Gold exploration in Chakariya Block (E -1 Stage) was carried out vide item no. MIE/CR/MP/1999/019 during the field season programme 1999-2001. Drilling was done over 800 meters strike length for assessing the potentiality of the auriferous 4 Previous Exploration zones identified by trenches. For detailed description please refer to the report titled “General Exploration for Gold Mineralization in Chakariya block, Sidhi district, Madhya Pradesh (Stage G2).” Geologically the area belongs to Dudhmania Formation of Mahakoshal Group of rocks. This Formation constitutes Mixed Oxide-Silicate facies BIF and fine grained clastics. Phyllite is the most dominant lithounit exposed in the block. Other rocktypes include: BIF, Scorodite and different types of quartz veins.

Primary foliation or bedding is manifested in the form of compositional and color banding in BIF and fine colored laminations in phyllite especially near the contact with BIF. Secondary structure in the study area is present in the form of folds in BIF and penetrative cleavage in Phyllite. Microscopic to 5 Geology mesoscopic folds are very well preserved in BIF. Rocks in the study area have undergone low grade of metamorphism.

Scorodite (resulting from oxidation of arsenopyrite) and Quartz vein grey are the two most positive indicators of gold mineralization in the block along with minor mineralization present in BIF and phyllite.

For detailed description please refer to the report titled “General Exploration for Gold Mineralization in Chakariya block, Sidhi district, Madhya Pradesh (Stage G2).”

Geophysical logging of all the boreholes drilled during FSP 2016-17 was carried out by deploying microlloger unit. The data acquired includes, Self-Potential, Single Point Resistance, Aerial/Ground Natural Gamma and Resistivity.Petrochemical studies of 10 6 Geophysical/Geochemical data samples was also carried out.
