NEW VENTURES
PHASE II MINING
The Hutti Gold Mine is producing at an average of 1600 tons per day from the 1st Phase Mining upto 20thLevel. As the upper level reserve is depleting gradually it was planned to develop the bottom level reserves and maintain sustainable production in long run at a feed grade of 5 g/t. To attain the targetted production, 2nd Phase Mining has started below 20th Level. Mallappa Shaft has been deepened up to 910.19 m depth with and necessary development to connect with New Shaft is under progress. Presently development works in 22nd, 24th and 26th level are in progress in all four reefs through Mallappa as well as Central Shaft. This also involves excavation of ore pass system, crusher chamber at 27th level, excavation for electrical sub-station at 26thlevel which has been planned and is being executed. All above activities will be completed well in advance before commissioning of the New Shaft.
NEW CIRCULAR SHAFT
The present system of transport of men and materials to the underground has become very old and not adequate to serve the need of the hour. Hutti Gold Mine is plagued with so many constraints when it comes to:
1. Reduction of time required for lowering and hoisting men from underground and increase of effective working hours2. Evacuation of men from underground within reasonable time in case of any emergency
3. Forcing required quantity of air for ventilation of underground workings
4. Lowering of heavy equipments to underground.
With all this in consideration, Hutti Gold Mine rightly conceived the need of an alternative access and today we are proud to say that we have completed sinking of a new vertical shaft of 6 m diameter and circular shape upto a depth of 960 m
