Chhattisgarh is among 19 States in the country where the Geological Survey of India (GSI) has proposed to take up aerogeophysical survey to explore new mineral blocks.
In the first phase, it has been proposed that, reconnaissance aerogeophysical survey will be completed with magnetometer and gravity sensors and in the second phase, high resolution airborne survey will be carried out over potential mineral zones identified from the reconnaissance survey.
A total of 8.13 lakh square kilometers of geological potential area in the country would be explored through outsourcing.
The potential area for aerogeophysical survey covers parts of the States of Andhra Pradesh, Telangana, Rajasthan, Karnataka, Chhattisgarh, Odisha, Madhya Pradesh, Maharashtra, Gujarat, Jharkhand, Bihar, Tamil Nadu, Uttar Pradesh, Kerala, West Bengal, Meghalaya, Goa, Haryana, Sikkim and Assam. The data generated through aerogeophysical survey will be shared with the concerned States for taking up further exploration works.
The Central Government has established the National Mineral Exploration Trust (NMET) on August 14, 2015. The NMET has a Governing Body chaired by the Union Minister In-charge of Ministry of Mines and an Executive Committee chaired by Secretary, Ministry of Mines.
The primary objective of the NMET is to promote regional and detailed mineral exploration in the country to increase overall mineral production and achieve sustainable development of the mineral sector.
GSI will also be making an assessment of bauxite ore deposits existing in Damchun block of Balrampur district in Chhattisgarh.
Notably, Chhattisgarh accounted for 6.07 per cent of the total bauxite production in the country in 2013-14, as per the annual report of the Union Ministry of Mines.
Gujarat had the maximum 32.41 per cent share in bauxite production while Jharkhand had 10.53 per cent share and Maharashtra had 9.51 per cent share.The remaining bauxite production was reported from Goa, Tamil Nadu and Karnataka, it stated.
Incidentally, the total value of mineral production (excluding atomic and minor minerals) in the country during June 2015 was `18194 crore. The contribution of coal was the highest at `662 crore (37 per cent).
Next in the order of importance were-- petroleum (crude) `5636 crore, iron ore `1847 crore, natural gas (utilized) ` 2164 crore, lignite `516 crore and limestone `490 crore. These six minerals together contributed about 95 per cent of the total value of mineral production in June 2015.
Production level of important minerals in June 2015 were: coal 465 lakh tonnes, lignite 39 lakh tonnes, natural gas (utilized) 2617 million cu.m., petroleum (crude) 31 lakh tonnes, bauxite 1524 thousand tonnes, chromite 220,00 tonnes, copper conc. 10,000 tonnes, gold 100 kg., iron ore 106 lakh tonnes, lead conc. 21,000 tonnes, manganese ore 173,000 tonnes, zinc conc. 130,000 tonnes, apatite and phosphorite 171,000 tonnes, limestone 249 lakh tonnes, magnesite 18,000 tonnes and diamond 2678 carat. The production of important minerals showing positive growth during June 2015 over June 2014 include ‘apatite & phosphorite’ (205.6 per cent), ‘chromite’ (43.6 per cent), ‘lead conc.’ (41.3 per cent), ‘zinc conc.’ (27.5 per cent), ‘copper conc.’ (13.7 per cent), ‘limestone’ (3.4 per cent) and ‘coal’ (2.2 per cent). The production of other important minerals showing negative growth are: ‘petroleum (crude)’ [(-) 0.8 per cent], ‘iron ore’ [(-) 5.9 per cent], ‘natural gas (utilized)’ [(-) 7.4 per cent], ‘lignite’ [(-) 8.7 per cent], ‘bauxite’ [(-) 10.0per cent], ‘manganese ore’ [(-) 13.8 per cent], ‘magnesite’ [(-) 24.7 per cent], ‘gold’ [(-) 27.5 per cent] and ‘diamond’ [(-) 31.9per cent], officials stated.
Moreover, Chhattisgarh had 7.48 per cent share in total value of mineral production in the country during 2014-15, according to the annual report of the Union Ministry of Mines .
As per the report, Rajasthan had share of 11.49 per cent, Gujarat ( 8.85 per cent), Andhra Pradesh ( 8.25 per cent), Chhattisgarh ( 7.48 per cent) followed by Jharkhand ( 7.37 per cent), Odisha ( 6.38 per cent), Maharashtra ( 5.35 per cent), Madhya Pradesh ( 4.70 per cent), West Bengal ( 4.32 per cent), Assam (4.04 per cent), Karnataka (2.96 per cent) and Uttar Pradesh ( 2.72 per cent).
The remaining States and Union Territories having individual share of less than 2.5 per cent all together accounted for remaining of total value of mineral production during the year under review, the report stated.
State-wise analysis revealed that during 2014-15, the value of mineral production have shown a mixed trend as compared to the previous year.
The States which have indicated an increase in the value of mineral production are -- Tripura (14.3 per cent), Karnataka ( 1.6 per cent), Bihar (6.6 per cent), Himachal Pradesh ( 16.5 per cent), Mehgalaya ( 61.6 per cent), Uttar Pradesh ( 0.8 per cent) and Chhattisgarh ( 0.7 per cent).
During 2014-15, mineral production was reported from 33 states and union territories which is actual reporting from Mineral Conservation and Development Rules ( MCDR) and fuel minerals from 23 states and estimation of minor minerals for all the 32 states and union territories of which the bulk of value of mineral production of about 94.18 per cent was confined to 13 States ( including off shore areas) only, it stated
Offshore areas are in leading position in terms of value of mineral production in the country and had the share of 20.27 per cent in the national output, the report stated.
