Name of the Project: Ingaldhal (Underground) Copper Mines Project (North Block) ML No 1125, village: Kunchiganahalu, Post Box No.4, Chitradurga-577501, State-Karnataka, of Hutti Gold Mines Ltd. Project Proponent M/s Hutti Gold Mines Limited, having its registered office at 3rd floor, KHB Shopping complex National games village, koramangala, Banglore-560047, & Mine office at Post Box No.4, Chitradurga-577501, State-Karnataka, is a Government of Karnataka Undertaking (Established in 1947 as Hyderabad Gold Mines), has the unique distinction of being the only producer of primary gold in the country. HGML has been active in the exploration, development and exploitation of gold deposits occurring in Karnataka. The Company's Corporate Office is situated in Bangalore and it operates two units- The Hutti Gold unit (HGU), in Raichur district and the Chitradurga Gold Unit (CGU) in Chitradurga district with an operating mine at Ajjanahalli (Tumkur District). HGU is a fully integrated unit with a capacity to produce 5, 50,000 tons per annum. The HGML currently processes ore from Hutti Gold Mine and two satellite mines at Uti (opencast) and Hira-Buddinni (Exploratory underground mine). Major expansion including the extended capacity of the metallurgical plan in phased manner is also under consideration. However, CGU's operations for gold mining and processing ore temporarily suspended and the company has diversified into wind form project and as established 9.3 MW in its leased premises. Ingaldhal Copper Mines (North Block) The North Block Mine (kunchiganahalu) is about 2.8 km north of the present Ingaldhal copper mine (Central Block). As a result of the drilling exploration carried out by the geological survey of India. A reserve of 2.5 lakhs tonnes of ore on an average grade of 1.46% Cu. Over a strike of 750 mts. Worked to a depth of 110 mts. has been indicated. Page 3 Pre Feasibility Report of Copper Mining project of Ingaldal Copper Mines Ltd. In view of the promising nature of this find and availability at comparatively shallow depth, the chitradurga copper company has taken up a mining lease during the year 1973 and has started developing the new block under the name North Block Project. The mine is not far away from the Central Block Mine. The development of this block can be carried out without any difficulty with the existing experienced staff, officers and additional machineries. The reserve of copper ore available in the north block will act as an additional reserve to the existing mine at Ingaldhal, in view of the short distance and help in stopping up production, the development of this property may establish a connection with northerly extension of copper bearing lodes exposed in the Ingaldhal mine working. Government of Karnataka sanctioned Mining Lease (No: 1125). Under the vide: Govt. of Karnataka notification No.CI.70:MM.2005, dt: 17-04-2007 subject to the condition that necessary clearance from the environment under the Environmental protection Act 1986 to be obtained. In pursuance of the above mentioned, now the proponent seeks Environmental Clearance for an area of 157.83 ha. (ii) Brief Description of Nature of the Project. Ingaldhal copper mine is situated near Bangalore-Bombay National Highway at about 6 Kms from Chitradurga town (Karnataka State). The Ingaldhal Mine is an underground mine which will be worked using the existing old openings. The copper bearing ore will be treated in a beneficiation plant with gravity separation, floatation and recovering copper. The plant is located near the mine site (Central Block) and is an integral part of the mines. The method of mining will be - overhand stoping by cut and fill method. Since back filling of the stopes will be continuously done, the location of the beneficiation plant is at Central Block. (iii) Need for the Project and its importance to the country. Hutti Gold Mines Ltd intends to mine 250 TPD of Copper. Hence, it is mandatory to obtain Environmental Clearance from MoEF, New Delhi. Currently the mine is not working. It is planned to carry out detailed exploration by exploratory mining. Page 4 Pre Feasibility Report of Copper Mining project of Ingaldal Copper Mines Ltd. (iv) Demand Supply Gap India's Copper demand will likely grow at least 8% to 10% as corporate build power units to meet their electricity demands. The slower growth rate is attributed to the sharp decline in the demand for jelly filled telecom cables, the largest user industry of copper in India. However, the demand from power cables, winding, industrial applications and construction industry has increased. Moreover, deficit in the other Asian countries helped the domestic producers to increase exports. The size of Indian Copper Industry is around 4 lakh tons, which as percentage of world copper market is 3 %. The major copper producing companies in India are as follows S.No. Name of the Company Cumulative Production 2007-08 2008-09 2009-10 2010-11 1. Hindustan Copper Ltd 44,734 30,036 17,516 2061 2. Hindalco Industries Ltd 3,23,900 2,97,800 3,33,300 45,725 3. Sterlite Industries 3,39,294 3,12,833 3,34,202 54,013 (India) Ltd 4. Jhagadia Copper Ltd 10,000 11,100 3,300 Nil Total 717928 651769 688318 101799 Unit: tons Demand Supply Analysis The future demand of copper is envisaged at 2.3 million tons in 2024-25. This is considered keeping in view the sectoral break up of future demand which is more realistic as compared to CAGR and projected GDP growth. To fulfill the demand the production of copper is also projected with due justification. The projected production of copper in 2024-25 comes to 2.8 million tons. This includes the production contributed by secondary source in addition to primary. The primary production will contribute 2.0 million tons whereas secondary production will be 0.85 million tons. This is justifiable production which will meet the future demand. (v) Imports vs. Indigenous Production. The domestic demand of copper and its alloys is met through domestic production as well as imports. Page 5 Pre Feasibility Report of Copper Mining project of Ingaldal Copper Mines Ltd.
