  1.    Exploration for primary source of Diamond.                                           Consequent upon the finding of Diamond bearing Kimberlitic/Olivine lamproite bodies in Dharambandha block of Nuapada district by this Directorate, investigation has been extended to the adjacent areas to locate more such bodies.  In the process approximately one Sq. Km of area was covered under geological mapping.  Trial excavation to the tune of 50 Cu.m, and generation of samples to the tune of 102 tones have been achieved.  The samples are under scrutiny for Tracy Diamond incidences in them.

 2. Search for precious and semi-precious stones in Subarnapur and Bolangir    districts.

 Basing on previously acquired information on the availability of Gem quality minerals like, lolite, corundum and garnet etc.  In the districts, geological investigations were taken up in the area.  In course of investigations 154 Sq. Kms was covered and 1,376 grams of gem quality garnets were recovered.  The exercise has resulted in locating 24 garnet occurrences in the area.

 3. Search for Chromites and Platinum group of elements (P.G.E.)

 Based on high-resolution aeromagnetic data acquired by this Directorate, Investigation for chromite and P.G.E. in parts of Dhenkanal, Jajpur and Keonjahr district was taken up. For the purpose an area of 0.6 Sq.Km was geologically scanned and 234 Geo-Chemical Samples were collected for analysis.  This analysis result so far obtained indicates a positive trend in the area.

4.     Exploration for Bauxite.

 Keeping in view the demand for small bauxite deposits, exploration for bauxite bearing plateaux in Koraput, Rayagada and Kandhamala Districts was taken up. In the process 104 Sq.Kms of area was geologically mapped and adequate number of samples were generated for analysis. The samples indicates alumina percentage in them varying from 58% to 37%.

 5.   Exploration for Iron ore.

 Detailed exploration was undertaken to assess the iron ore of Khandadhara area in Sundargarh district on behalf of Kudhermukh Iron ore Company Ltd.  The work involved was 21 Sq.Km of geological mapping and 506 m of drilling with generation of 166 nos. of samples for analysis. Further work is continuing.

6. Assessment of heavy mineral contents in the beach sand of Orissa Coast.

 Detailed geological work was undertaken in pitisal sector of Puri Coast for the purpose.  Approximately 1.5 Sq.Kms of geological mapping 2216 m. drilling and generation of 2,216 numbers of samples was achieved.  The samples are under examination for assessment of grade and reserve in the areas.

7. Investigation for Graphite

 Geological investigation was carried out over an area of 110 Sq.Kms in parts of Rayagada district.  A total of 55 nos. of samples were generated and are under analysis at present.
