The principal model for gold mineralization at the Kirazli Gold Property is a high-sulphidation, epithermal gold deposit. Examples of this kind of deposit in the world are Yanacocha, Pierina and Alto Chicama in Peru. Most high-sulphidation deposits are large, low-grade bulk-tonnage systems (Yanacocha), though vein-hosted high-sulphidation deposits also occur (El Indio). At Kirazli, gold mineralization is hosted within heterolithic phreatomagmatic/phreatic breccia bodies cutting through Miocene-age andesitic tuffs. Mineralization can generally be subdivided into two main types:- A regional low-grade gold zone that underlies much of Kirazli, broadly enveloping the high-grade gold zones. This low-grade mineralization occurs both above and below the redox horizon. The widespread, low-grade mineralization is interpreted to be early and may be associated with the broad epithermal alteration that resulted in the chalcedonic silica (the second silica event);- Four elongate bodies of high-grade gold mineralization occur in the advanced argillic zone overlapping slightly the bottom of the 1 km-long silica cap and the silica roots. High-grade gold mineralization also shows a strong spatial relationship with the margins of heterolithic breccia bodies. These bodies transect the redox boundaries. The subhorizontal section below the silica cap is in oxide or sometimes in transition zone while the bottom of the vertical section associated with the silica roots is in sulphide.- The first high-grade body (A) is followed over more than 400 m in a northsouth direction from section 30650N to section 30250N. It coincides with the subvertical silica root and the phreatic breccia pipe and extends in the advanced argillic alteration mostly east of the root. Towards the top, it flares and extends subhorizontally eastward for 100 m below the silica cap end the subhorizontal eastern extension of the phreatic breccia but affects its lower portion too. The highest grade section coincides with the flat portion below the silica cap. Grades there may be spectacular as in drill hole KD-09 with 4.6 g/t Au over 38.5 m.- The second high-grade body (B) is followed over 150 m in a north-south direction from section 30100N to section 29950N. It coincides with the advanced argillic alteration immediately west of the silica root but does not affect it. Towards the top, it extends westward for 50 m below the silica cap and affects its lower portion too.- The third high-grade body (C) is followed over 250 m in a north-south direction from section 30100N to section 29850N. It coincides with the advanced argillic alteration immediately east of the silica root but does not affect it. Towards the top, it extends eastward for 50 m below the silica cap and affects its lower portion too. The highest grade portion coincides with the flat portion below the silica cap. Grades there may be spectacular too as in drill hole 10-KD-143 with 5.4 g/t Au over 39.5 m.- The fourth high-grade body (D) is followed over 100 m in a north-south direction from section 29900N to section 29800N. It only affects advanced argillic altered andesites and phreatic breccias following a vertical direction until it bends to the west below the silica cap.
