� Thousands of years of ago when a child found a shiny rock in a
creek, the human race was introduced to gold for the first time.
� Its brilliance, natural beauty and its great malleability and
resistance to tarnish made it enjoyable to own it.
� Humans in ancient and modern civilizations almost intuitively placed high value on gold by equating with Gods, Power, Beauty
and Cultural elite. Passing through fire, during its evolution
process.
� Gold has become synonymous with purity, the reason for its
magnanimous usage during wedding and religious occasions.
STORY OF GOLDSTORY OF GOLD
GOLD MINING HISTORY
� Ancient Mining Dates back to 2000 years
� Mining in the early part of 16th Century (During Vijaynagar
Kingdom)
� Modern gold mining commenced by the end of 19th Century.
WHY GOLD MINING?
• Gold is small volume high value commodity
• In this world of uncertainties, gold is and will always be treated as “Safe Haven” by the general investors.
• A reliable commodity to hedge against inflation
• An excellent tool for asset diversification since the world is increasingly looking at gold.
• Continues to remain as a most treasured possession of both men and women in India, be it a rural or urban.
• Is used as a reserve in the countries
• Gold is a precious due to perceived rarity.
• Gold is a resistant to corrosion or oxidation, unlike most base metals like ours.
WHY GOLD MINING? (…..Continued)
• Gold is an inseparable part of Indian psyche and ethnically is considered as an asset and ideal investment option.
• People consider gold as having a closer link to money than any other metal
• The attractiveness of gold as a piece of jewellery has unprecedently increased at the same time it can be pledged and exchanged for money
• However, our monetary system is not directly linked to or backed by gold. Once converted into jewellery it remains idle. Therefore, to many, particularly in developed countries, gold seems to be rather useless metal. Yet, gold mining as a business and an occupation is useful both to the entrepreneur and the host Government. Therefore, the equation “gold mining equals money mining” is true in practical terms. Gold mining has significant advantages for a developing country.

This is the general geological map of Karnataka showing the distribution of
Precambrian Green stone belts in which various gold deposits are located.Hutti Maski Belt is one such most promising and the position of the Hutti Belt in relation to the other Precambrian Green Belts of Karnataka.Particularly Eastern green stone belts namely Hutti, Ramgiri, Kolar are
important as the major working gold mines fall in these belts.

INTRODUCTION
� Hutti Gold Mines Company Limited (HGML), a Government of Karnataka Enterprise, established in 1947, has the unique distinction of being the only producer of primary gold in the country, which possess the infrastructure, expertise and experience.
� HGML has been active in the exploration, development and exploitation of gold deposits in Karnataka.
� The company’s Corporate Office is situated in Bangalore and operates two units - The Hutti Gold Unit (HGU), in Raichur district and the other Chitradurga Gold Unit (CGU) in Chitradurga district .
� HGU and CGU are fully integrated units, with capacities to treat 6,00,000 tpy and 1,30,000 tpy of ore respectively.
� The HGU currently, processes the ore from Hutti mine and two satellite mines, Uti (opencast) and Hira-Buddinni (Exploratory underground mine).
� Major expansion including the extended capacity of the metallurgical plant in phased manner, is also under consideration.
After closure of Bharat Gold Mines Limited (BGML) in 2001, HGML is the only unit processing gold from ore stage. Private sector HINDALCO processes gold as a by-product while processing copper.
MILESTONES IN THE HISTORY OF HUTTI GOLD MINES
1887 Gold Mining was undertaken by "Hyderabad (Deccan) Company" for the Nizam of Hyderabad.
1880 – 1920 Modern Mining took place between by M/s. John Taylor’s and Sons.
During the period between 1902 to 1918 only the Main Reef alone produced 3.8 lakhs tonnes of ore and yielded 7.41 tonnes of gold @ an average grade of 19.45 g/t. was mined upto 1052 m. depth.
1920 Mine closed down due to paucity of materials and funds, attributable to World War I.
1938 Detailed exploration by geological & geophysical surveys, diamond drilling and dewatering of the Village Reef mine were conducted, which resulted in rediscovery of Village, Zone - I and Oakley's Reefs.
1947 On 8th July 1947 "Hyderabad Gold Mines Company Limited" was incorporated and the mining operations were entrusted to John Taylor & Sons by the Nizam of Hyderabad.
1956 It was renamed as "The Hutti Gold Mines Company Limited" (HGML) with the formation of Mysore State (now Karnataka) when the states were reorganized.

So far India was averse to foreign collaboration in the field of mineral exploration (-exploitation).
To day, it seems, she is too eager to solicit it. Both are extreme steps. We should indeed seek foreign collaboration, partic ularly of those agencies which have vast experience in the agencies which have vast experience in the specific field. But this can not be in place of our own effort. It should be only added to our own strengt h.
MNCs normally will not be interested in low-medium t onnage deposits. These may be given to indigenous private companies, or to co-operatives. Co-operative gold mining was, and p ossibly still, is, an established practice in the former USSR and present China.
MNCs have to be inducted for this purpose with appli cation of state-of-the-art technology. The mining sector, which has be en thrown open for private entrepreneurs and MNCs, has to provide with fast disposal and support from the Government so as to attract more a nd more investments.
COLLABORATION/JV
SUMMARY AND CONCLUSION:
Enhancement of Gold productionEnhancement of Gold production1. Chigargunta deposits (Kolar schist belt), Yeppammana mine (Ramagiri
schist belt) and Bisanattam (Kolar schist belt) deposit which were producing gold.
2. Treatment of Tailing Dump at KGF3. Increasing Gold production in existing mines of H GML leaseholds.
Appropriate changes in the mine layouts, adoption of improved mining methods with optimum mechanisation, adoption of improved gold recovery techniques suited to specific ore types and fast development of already proved nearby lodes of lower grades for shallow level exploitation may bring in a significant change in the present scene.
4. Augmenting by-product gold production.In India, HCL is producing by-product gold from copper concentrates. The Hindalco Industries is producing by-product gold from imported copper concentrate. It is necessary to increase production of by-product gold.
5. Regional and detailed exploration
6. Regional Exploration for primary gold
7. Detailed Exploration of primary gold
8. Secondary gold
9. Modernisation of Exploration, Mining and Gold Recovery Techniques
10. Cluster mining – There are number of isolated sm all gold deposits, which calls for improved methods of narrow vein min ing for theireconomic exploitation. Introduction of small scale mining culture in gold industry is a need of the day. Various options like cluster mining, having common facilities, probable caravan type gold treatment plants etc. may find relevance once this culture is inducted.
11. Adoption of modern gold extraction techniques s uch as CIP & CIL, Heap leaching and Pressure leaching & Bio-leaching.
Global miners eye Indian gold reserves
In recent years, global mining majors are making a beeline to India in the hunt for gold and diamond. Overseas prospecting companies who are already havi ng satellite data on the location of India’s gold rese rves are likely to soon stampede their way into India, usher ing in the next big gold rush after china. Canadian prosp ecting firms, who are already on the prowl for suitable In dian joint venture partners, are making the first advanc es.
Mineral Potential of the Indian Terrain
Geologically, the Indian
terrain is largely comprised
of precambrian rocks.
Similar rocks are known to
