Name of the Project: Ingaldal (Underground) Copper Mines Project, village: Ingaldal, 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) mine, 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. Ingaldal Copper Mines Workings for Copper were first noticed by R.B Foote in 1886 on the Belligudda Hill of Ingaldal area. The department of mines and geology carried out prospecting of the mineral bearing areas in the state in 1927, and selected Ingaldal for its first operation. The exploratory work consisted of cleaning up the old adit for a length of 6 mtrs. A winze was also sunk to a depth of 10 mtrs below the old workings. The results indicated that mineralization was Page 3 Pre Feasibility Report of Copper Mining Project of Ingaldal Copper Mines Ltd. fairly strong on the northern section averaging 8% copper while on the south pyrite was more pronounced. The prospecting work carried out was of a few feet laterally and at depth, no attempt was made at detailed exploration to estimate the possible reserves and grade. HGML obtained Mining Lease (ML No: 2490, Period: 6-3-1993 to 5-3-2013). Mining activities were held at Ingaldal Copper Mine from 1965 to 1994. Mining work has been suspended in 1994. Now HGML is planning to restart the Copper mining at Ingaldal by utilizing their experience of operating (mining & beneficiation) a copper mines. Accordingly, Mining Plan has been prepared in 1989 for submission to Indian Bureau of Mines (IBM) for accordance of its approval. The ultimate rate of production (maximum rated capacity) of copper ore in ingadal copper mine is 250 TPD. M/s Ingaldal Copper Limited has been granted the mining lease (No. 2490) vide letter no. KNT/CTD/CU-1-SZ dated: 29.03.1989 from Indian Bureau of Mines over an extent of 259 ha in Ingaldal in Chitradurga District of Karnataka state. The lease period granted will be expired in the year 2013. (ii) Brief Description of Nature of the Project. Ingaldal copper mine is situated near Bangalore-Bombay National Highway at about 10 Kms from Chitradurga town (Karnataka State). This mine was earlier worked during 1965 to 1994 period. Between 1964’s and 70’s State Department of Mines and geology & GSI had carried out detailed exploration of this deposit. The Ingaldal Mine is an underground mine which will be worked using the existing openings. The copper bearing ore will be treated in beneficiation plant with froth floatation technique for recovering copper. The beneficiation plant is located near the mines site 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 plant is within the mining lease area. The maximum rated capacity of mining and beneficiation plant would be 250 tons per day. Page 4 Pre Feasibility Report of Copper Mining Project of Ingaldal Copper Mines Ltd. (iii) Need for the Project and its importance to the country. Hutti Gold Mines Ltd intends to mine & beneficiate 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. (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.

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 Page 5 Pre Feasibility Report of Copper Mining Project of Ingaldal Copper Mines Ltd. 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.
