A tentative extent of around 14.5 Sq kms situated in the western part of the block falls under Chikkanahallli Reserve forest area and a tentative extent of around 0.5 Sq kms of area situated in the South – Eastern part of the block is covered under Ayyarahalli deemed forest area. The remaining area of 187 Sq Kms falls in Revenue and patta lands of Mysore, Heggadadevanakote and Nanjangudu taluks of Mysore District. 3. SCOPE OF WORK: The Successful Bidder/agency shall provide necessary technical support and shall under take G4- stage of mineral investigation works in the block bounded by the co- ordinates as specified at clause no 2.1 of the document over an extent of 202 Sq Kms for identification of mineralization of gold and associated elements. The G4 investigation work is required to be carried out in the following 3 stages. 3.1 Stage – I : Large scale geological mapping. 3.2 Stage – II : Detailed geological mapping of mineralized zone(s). 3.3 Stage – III : Scout drilling. 3.4 Ore Reserve estimation: The detailed scope of work is furnished below. 3.1 Stage – I : Large scale geological mapping: The agency shall carry out large scale geological mapping of 202 Sq kms bounded by the geo co-ordinates as specified at Page 2 of 53 SEAL AND SIGNATURE OF THE BIDDER LTE No. KIOCL/MED/MOM/KA/08 Dtd. 3rd Mar 2017 point no.2.1 of the document. The agency shall identify/isolate potential mineral bearing areas/zones of gold and associated from the total extent of 202 Sq Kms on the basis of large scale geological mapping in 1:12500 scale, geochemical sampling and analysis of the available aerial survey records & investigation reports. The details of the work to be performed in Large scale geological mapping is furnished below. 3.1.1 Literature survey: a. Agency shall be responsible for collection, study and interpretation of various Geo-Stat imageries, aerial photographs, aero geo-physical survey data, previous investigation geological reports, maps conducted by various other organizations in the subject area so as to demarcate the potential targeted gold and associated elements mineralization. KIOCL will provide necessary assistance in obtaining the reports and maps from the respective organizations. b. The agency shall incorporate all the findings of the literature survey in stage-I investigation report. 3.1.2 Geological mapping: a. The agency is responsible for carrying out large scale geological mapping of the block (202 Sq Kms) in 1: 12,500 scale for identification of mineralization of gold and associated elements. b. The area of 202 Sq Kms is required to be geologically and structurally mapped for identification of mineralized zones of gold and associated elements. c. Geological and structural studies of the various litho units available in the area are to be carried out for identification of gold and associated elements mineralization. d. Various geological parameters like length, width, strike and dip of the gold and associated elements mineralization zone(s)/ bands are required to be identified and mapped. e. Agency is responsible for collection of various geological field inputs obtained from old workings available within the block and required to make geological interpretations accordingly. These observations and interpretations shall be brought in stage I investigation report. f. The agency shall measure the co-ordinates of the each sample collection points, outlines of geological lithounits, surface exposures, old working etc. by using handheld GPS and to be marked on the maps.

The agency shall collect 300 nos of Surface and bed rock samples from the mineral bearing area(s) for identification and delineation of gold and associated elements mineralization. b. The surface samples are to be collected from surface exposures, escarpments, nullah sections etc. c. In case of contamination of surface samples due to agriculture or any other reasons the agency shall collect the sub surface samples using handheld auger technique. d. The agency shall collect 150 nos of stream sediment samples in order to study geochemical behavior of gold and associated elements in the stream sediments as well as to study the gold and associated elements of the provenance transported by the streams. Stream sediment samples should be collected from morphological traps present in the stream. e.
