Gold Investigations in Malanjkhand Area with Special Reference to Garhi Dongri Prospect, Madhya Pradesh

Age old gold panning along the streams, ancient workings for gold mineralization in the quartz veins emplaced in Malanjkhand granitic pluton (MG) along the peripheral contacts of older rocks of Amgaon Gneiss (AG) and Nandgaon Volcanics (NV) besides shear controlled zones drew the attention of present authors to take up detailed survey. These quartz veins are the locales for future exploration of copper-gold mineralization. Garhi Dongri (Gd) and Khandapar (Kdp), occuring at the peripheral contacts, may be gold rich and copper poor in mineralization and are very significant Gidori (Gd) and Pipardhar (Pd) areas, falling within sheared zones, may be considered as prospective sites for Malanjkhand-type rich copper and poor gold mineralization. Shitalpani(Stp) and Kundikasa(Kd) may fall under poor copper and/Or poor gold categories. GD prospect is found to be a promising for gold mineralization. Stp is under investigation and preliminary results suggest that it may be a poor-copper(?) prospect. Mineralogical association and alterations in GD and Stp are very similar to mineralogical alterations at Malanjkhand porphyry copper deposit. Gold rich and gold poor deposits are known in the northern chilean belt of porphyries and many other porphyry deposits.
