Reconnaissance Survey (G-4 Level) For Iron Ore Exploration Dalli Area, In 100 Km2 Area District: Balod (Chhattisgarh)

1. Introduction:

In view of the MMDR amendments act - 2015, Mineral (Evidence of Mineral Contents) Rule 2015 and Mineral Auction Rule - 2015, Ministry of Mines, DGM, Chhattisgarh identified the block for exploration and to take up the block for G-4 level of exploration under NMET funding.

2. Location of the Block:

The district headquarters about 26 km from the block in the east. The nearest township is Dalli Rajhraa. The block is located in the Survey of India Toposheet No. 64 H/2. The coordinates of the corner points of the block is given above (in summary) and covers an area of nearly 100 km2

3. Physiology and Drainage:

Physiographically, the district can be divided into three distinct parts (i) Hilly part of the west, (ii) Southern plateau and (iii) Plain region of eastern part. The ranges of Maikal and Mangata are spread in western part of the district. The general slop of the district is towards east. All the river of the district flows in the eastern direction. Sheonath is the most important river and the important tributaries of the river are Amner, Jonk, Ghumariya, Pairi and Hant.

4. Previous work:

Various agencies have studied the iron ore deposits of Rajnandgaon district. Detailed geological mapping of this region was conducted by Geological Survey of India in 1964-65 and in the year 1983-84, the Geological Survey of India carried out the survey work in Manpur-Damkasa-Kotri area and estimated the reserves assuming the thickness of iron ore as 30 meters. (Details given below)

1. Mainkar D and Singh SK (1985-86) carried out investigation work during the field season 1985-86, in Rajnandgaon district for Iron ore deposits. During reconnaissance survey 111.57 km2 area mapped on 1:50,000 scale and various lithounits were plotted. Detailed work have been carried out in 2.15 km2 area along with detailed mapping and structural studies on scale 1:4000. A Total probable resources of 1.062 M.T. of iron ore have been estimated as given earlier Kanni- dongri contains 0-4945 M.T. of (+ 64% iron contents) iron ore and

Kukrel probable reserves they are likely to increase considerably. The other deposits of the area on Dongar bar and jap dongri. Probable reserves of these hills are upto 5 million tones (D.G.M.) - 1980-81) Thus sthe total reserves can be placed around 6 million tones.

Pandey JL (1980-81) The Directorate of Geology and Mining, M.P. have located a rich iron ore deposit in the hills of Kanni-Dongri, Jup-Dongri and Dongar-Bor about 15 km in the east of village Boria-Tibbu, district Rajnandgaon. The iron ore deposits occur associated with the Banded Hematite Quartzite (BHQ) of the iron ore series of the Archaeans. It occurs as discontinuous patch and lensoid masses of varying size. The rich ore is dark steel grey in colour, with characteristic metallic lusture on freshly broken surface. The ore is hematite with maximum Fe content of 68%. In all 13 pockets have been delineated. A total of 123 samples collected from insitu deposits and float ore have shown very encouraging result with +68.25% Fe content and very low silica, alumina. On the basis of survey a reserve of around 5.00 million tonnes of high grade iron ore is inferred.

6. Objective of the proposed exploration programme

With this background information it is proposed to take up in Preliminary survey (G- IV level exploration) for Iron ore in area of Balod District, in part of Toposheet number 64H/2.

2 boreholes are proposed to be drilled with 100 m average depth on 800 m X 800 m grid interval. A total of 5.00 sq. km. area of detailed mapping is also proposed in 1:4,000 scale core samples will be collected and XRD work will be carried out. The Exploration work will be surveyed by the total station.

The basic Geosciences data provided by GSI has been studied and evaluated. Based on the evaluation the present exploration programme has been formulated to fulfil the following objectives.

1) To carry out geological mapping on 1:12,500 scale and demarcate the rock types of iron bearing formations, to identify the surface manifestations and lateral disposition of the mineralized zones (ore body). 2) To collect surface samples and analyze them for Fe content and decide further course of exploration programme. 3) In case, surface samples give positive results and Remote Sensing Studies shows probable extension of the mineralized zones (Ore body) on surface & structural

NMET/Iron/Dallirajhara/Nagpur/21.05.2018 8

control, then to drill 5 scout boreholes which in turn will decide the future course of exploration programme at G-3/G-2 category of UNFC. 4) To estimate reconnaissance 334 level of resources.

7. Proposed scheme of Exploration: 7.1. In accordance to the objectives for the block, the exploration programme is formulated. The exploration shall be carried out as per Minerals (Evidence of Mineral Contents) Rule-2015. Accordingly, the following scheme of exploration is formulated in order to achieve the objectives. The details of different activities to be carried out are presented in subsequent paragraphs. 7.2. Geological mapping: Geological Mapping will be done on l: 12,500 scales. Rock types their contact, structural features will be mapped. Surface manifestations of the mineralised zones available along with their surface disposition will be marked on map. Samples of various litho-units for Petrological studies from ore bodies will be taken during the course of geological mapping.

8. Surveying:

The block boundary will be surveyed by Total Station in WGS-84 datum for demarcation of block boundary points. Survey party will be associated with stream sediment sample and bed rock sample collection by taking up the points and plotting its location on map for proper interpretation of the sample data. Survey party will also be associated with Geological Mapping and the litho-contacts will be plotted for finalization of Geological map on 1:12,500 scale. During drilling scout borehole fixation and determination of reduced level and co-ordinates of the boreholes will be undertaken. If mineralized zones are identified, contouring of the surrounding areas of ore bodies would be done on 5m contour intervals along with survey of surface features.

9. Core Drilling: Two boreholes are proposed to drill upto the depth of 100 mts. 9.1. Drill Core Logging: The drill core will be logged for rock types, structural features, textures, intersection of ore zones, type of mineralization and occurrence of various minerals. 9.2. Drill Core Sampling: During the geological logging of drill core, mineralized zones will be marked based on concentration and Lithological variation. 200 Nos

of samples (primary) will be analyzed for SiO2, Al2O3, Fe2O3, P2O5 & S. 9.3. Whole Rock Analysis: 10 N0s of samples shall be subjected to whole Rock analysis for SiO2, Al2O3, Fe2O3, P2O5, TiO2, MnO, CaO, Na2O, K2O+H2O, MgO, & S radicals to check the rock types, their variation in chemical composition. 9.4. Petrological & Mineralogical Studies: During the course of core logging & mapping 20 samples from various lithounits intersected will be studied for petrography and 20 samples from mineralized zones will be studied for the ore mineral assemblages and their distribution, alteration, enrichment etc. in polished sections.
