Investor Presentation

  1. 1. Nundydroog Mine (NM)  The Kolar Schist Belt (2700Ga) hosting the well known Gold mine is one of the richest gold mineralised areas amongst the Archaean greenstone belts of the world.  These can broadly be classified into three distint lithounits, i.e (i) Mafic schist (ii) felsic schist (iii) BIF and graphite-sulphide schist in order of abundance. The mafic schist is the dominant rock type occupying the western portion of the schist belt and hosts most of the auriferous lodes. It comprises metamorphosed basalts (pillowed), gabbro and pyroxenite, now represented by hornblende schist, amphibolites, and ultramafic schist. These groups of mafic rocks represent composite flows and intrusive sheets.  K.G.F has produced among the richest gold deposits in the craton from one of the deepest underground mines of the world. The mines reached a depth of about 3211mts. (113th level) from surface.

  4. 4. Mine Related Activities  In the field of plant constructions, it undertook designing, manufacturing, installing, and commissioning of headgears and winders, creation of ore handling, cursing, and stowing plants (manufactured by its signaling division according to customer needs), locos, signaling equipment and the hoist equipment.  The division comprised of four (4) workshops which were known as champion Reef workshop, Nundydroog workshop, central workshop-mechanical and central workshop electrical. The main function of these workshops were to maintain mine and mills in KGF area, and to design, manufacture, and provide sale and after sale service of engineering products.

  6. 6. Manpower  Employed 13000 people at one point of time during the peak of its operations. During the year 1990-91, there were over 10000 employees which reduced to about 3500 at the time of the closure of the operations. Services of all the employees of the company had been terminated and all their liabilities have been settled under Special Benefit package.

  8. 8. Power  This plant had an installed capacity of 42MW at 25 cycles per second (cps) and it generated nearly 21 MW. BGML also had diesel generator (DG) sets which were used during emergencies. Land  BGML has a freehold right on its mine land of over 12000acres at KGF. The company has leasehold land of 551 acres at Chigargunta Mine (Andra Pradesh), 105.23 acres of land at Yeppamana Mine (Andra Pradesh) and 416.18 acres of land at Old Bisanatham Mine (Andra Pradesh), with varying dates of expiry of leases.
  9. 9. Tailing  Mining and subsequent milling operations for productions of gold have contributed to over 30 millions tones of tailing dumps in the KGF region. Most of the dumps contain tailings of treated free milling ores and Kennedy’s dump consists of tailing of both refractory and free milling operations. Davy John Brown (DJB) had carried out a study on techno-economic feasibility for extraction of gold from the tailings. Mining Reserves Broad level estimation of gold reserves was carried out by BGML during the year 1997 for all the operational mines. Details of the mine reserves are provided.

  15. 15. The Five Year Projection of a Gold Mine The Projected Revenue 150 million tonnes of ore x 5 gm/ tonne = 750,000,000 GM 1 kg is 1000 GM = 750,000,000/1000gm= 750,000 kg 750,000 kg x 3300000 lacs = 2,475,000,000,000/ 247,500 cr
  16. 16. Cost of Sales Total cost of equipment = 8000 cr Cost of human resource= nil on equity Overhead cost, Cost of energy Cost of community development= 76,625 cr Gross profit= 170,875 cr Total ecb required = US $ 300 million Gross profit in 5 years= US $ 28 billion Tax free returns controlled from a Vanuatu company.
  17. 17.  Mysore Mill  The Mysore Mill is located in KGF adjacent to the MCA Mine. The mill was not operational at the time of closure as the total ore production from the ND, CG, OB, and MCA mines was less than 700 TPD and the entire ore was being processed at the ND mill.  Ramgiri Mill  Ramgiri Mill is located in Anantapur District of Andra Pradesh near the YP mine and processes the ore mined from RM mine. The production capacity of the mill was 250 TPD. The mill was commissioned in 1984, as part of the integrated mine-mill complex of the YP mine.  Heap Leaching Plant (HLP)  BGML operated a HCP in KGF located at a distance of 4km from the Kennedy’s (tailing) dump. The plant installed capacity was 500 TPD. It was in operation from 1986-87; hence presently stands closed. Until closure he plant had treated 0.38 Million tones and produced 303.67kg gold.
