1. Kariganur Mineral Mining Industry
Kariganur iron ore mine is an ISO 14001:2004 certified mechanized mine bearing M.L. no. 1799, with an extent of 199.43 hectares. It is situated in the NEB range of Kariganur village, Hospet taluk, Bellary district, Karnataka.
Hematite iron ore deposits of this mine are enclosed within the Precambrian sedimentary iron formation, commonly known as Banded Hematite Quartzite (BHQ) and Banded Hematite Jasper (BHJ).
The general strike of the iron ore reef runs along north west-south east, whereas the dip of the ore body is 60-75 degrees south western. There are two ore bodies – eastern reef with a strike length of 370 m and an average width of 55m; and the middle reef extending from east to west, with a strike length of 700 m and an average width of 45 m. The eastern reef consists of hard and massive steel grey hematite, with specific gravity between 4.9 -5.2. It is best suited for the production of high density aggregates used for coating pipes underwater, especially in oil well drilling and counter weights. The tumbler index is as high as 92. This ore has also been found suitable in the construction of nuclear plants.
The mine is totally mechanized with modern mining machinery. Entire strike length of the ore is opened up. The same ore body continues in all the three adjacent mines. The common boundary working permission has been obtained from the Director General of Mines Safety under regulation 111 of MMR 1961.
The sequence of mining operations in the hard ore body zone involves drilling DTH holes and blasting with ANFO and slurry explosives, using millisecond delay detonators/raydet and detonating fuse. The bigger boulders generated during blasting are broken down to the required size by the rock breakers. Few boulders are separately, manually loaded to the tippers and then fed to the crushers and screening plants based on the buyers’ demand. Further high grade ore is blended with low grade and sub grade ores in appropriate quantities in order to conserve and respectively prepare to suit the demand of the buyer.
Our management is concerned about the environmental imbalance created by mining activities and hence we have adopted various eco friendly practices and built engineered structures to conserve nature. Our management has prepared a mining plan for a conceptual period. During this period, the entire broken area of the mine is restored to its original aesthetic beauty.
2. Hothur Traders Mines
Malagolla iron ore mine of Hothur Traders, is a mechanized mine bearing M.L. no. 2107/2313, with an extent of 32.28 hectares. The mining lease area is situated 10 kms from Sandur, in the Kumaraswamy range of Sandur taluk, Bellary district, Karnataka. This mine is operated using modern mining machinery by open cast mining method. Our mining methods are environment friendly and ensure strict adherence to safe mining techniques.

3. Mehboob Transport Company
Our Company owns Vittalapura iron ore mine with mining lease no. 2568, for an extent of 16.19 hectares. The lease area is located at a distance of 25 kms from Bellary. It is situated in Bellary Reserve Forest (Copper mountain range) of Vittalapuram village, Sandur Taluk, Bellary District, Karnataka.
Iron ore in this mine occurs in the form of reef and is operated by opencast mechanized method with the combination of hydraulic excavator and tippers. The iron ore hard in situ rock is broken by drilling with DTH drills and by blasting with explosives.
The mine functions in a systematic, sustainable and scientific method. High standard eco friendly measures are followed by constructing structures like check dams, gully plugs and retaining walls. Many Agave plants and other local spices have been planted on inactive dump slopes.
4. Trident Minerals
Trident Minerals is located at a distance of 20 kms from Hospet, in the venkatgiri village of Bellary district, Karnataka for an extent of 32.27 hectares.
Iron ore occurring in this mine is in the form of reef and is operated by opencast mechanized method with the combination of hydraulic excavator and tippers. The hard overburden is crushed to generate aggregates to be used for construction, and as road metal. We are aware of our responsibility towards the environment and hence have adopted eco friendly mining methods.
5. Trident Mining Company Pvt. Ltd.
Our Company possesses a mining lease with M.L. no.1732, for an extent of 5.26 hectares. Located at a distance of about 20 kms from Hospet, lies the mine where the hard in situ rock is broken by drilling and blasting. The mine is worked by forming systematic benches by gradually advancing side ward lowering of benches, and worked across and along the strike directions of the reef.
We maintain a green cover in all our mining areas and are habitual in practicing scientific and sustainable mining.
