There are 3 prospects in the West Shiraz Kohn area, located about 70km east of Isfahan. An old kaolin prospect is located about 70km west of Isfahan and about 50 km south of Kahang porphyry copper deposit. Part of this prospect is actually a kaoilin mine. The alteration system covers an area of 1km by 5km and contains sericite, kaolinite and silica alteration surrounded by propylitic alteration. Leached cap and strong silicification at this prospect shows upto 0.2% copper and 0.25 g/t gold.

The second mineralized zone in this area is called Kalchue is located south of the Kaolin mine.

The area is underlain predominantly by andesitic to dacitic tuffs and minor flows. A granodiorite was also observed, possibly intruding the volcanics. Float of low-sulphidation epithermal type hydrothermal breccia and vuggy chalcedonic silica veins were observed in argillic (silica-clay-limonite) altered andesitic volcanics ridges at 2 parallel ridges surrounded by propylitic alteration (photo 1). One sample reportedly returned 0.42ppm Au, 37.1ppm Ag, 3060ppm Cu, 21.1ppm Zn, 364ppm Pb, 3.1ppm Mo, 714ppm As and 761ppm Bi. No vein outcrop was found.

About 800m further west, a N-S trending vuggy silica vein, about 4m x 50m, in widespread argillic altered andesite was noted. There was also recent shallow pitting in a 340o trending silicified ridge, 50m x 300m, containing limonite fracture fills. The locals probably tried prospecting for Au and gave up.

The third prospect and is underlain by propylitic altered dacitic crystal lithic tuff. The mineralization consists of a low-sulphidation epithermal crystalline quartz vein zone. The area had been locally mined for copper in the 1980s as shown by an adit below the ridge and several small pits on top of the ridge (Photo 2). Malachite stains up to >1% were noted in several outcrops. Chalcopyrite and minor galena were also observed. A sample taken here, OR-55.1, returned 7.66ppm Au, 18.6ppm Ag, 4.57% Cu, 1410ppm Pb, 210ppm Zn, 5.4ppm Mo, 169ppm As and 37.3ppm Bi. Another vein zone is located nearby but was not visited due to time and weather constraints.

The vein zone has a trend of 5o and dips 80o to the E. The vein strike length is about 400m. The zone consists of subparallel veins within a 2 to 5m zone. The main vein is about 0.8 to 2.5m wide. There are at least 4 vein stages. There was an intial phase of wallrock vein breccia (andesite clasts floating in vein quartz matrix), followed by base metal sulphide-bearing crystalline banded quartz vein, another episode of quartz vein breccia (vein quartz clasts in quartz vein matrix) and lastly by 1-5cm wide barren milky quartz veinlets (Photo 3).

In the West Shiraz Kohn area the old kaolin alteration system covers an area of 1km by 5km and contains sericite, kaolinite and silica alteration. Leached cap and strong silicification at this prospect shows upto 0.2% copper and 0.25 g/t gold.

At the second prospect in the West Shiraz Kuh area, the argillic-altered hydrothermal breccias and vuggy silica veins shows quartz textures that are found at the high level parts of a low-sulphidation epithermal Au system. Although this would mean that Au may increase at depth, the occurrence seems to be restricted and no large vein zones are developed.

The third prospect is called Kalchue. The quartz vein zone at Kalchue is probably at the lower part of a low-sulphidation epithermal Au system. This is evidenced by the fact that the wallrocks are propylitized, ie. higher end of the temperature of formation range, the quartz vein is fine to medium crystalline and basemetals especially Cu is high. One sample form quartz vein of 2.5m by 400m long returned 7.66ppm Au, , 18.6ppm Ag, 4.57% Cu, 1410ppm Pb, 210ppm Zn, 5.4ppm Mo, 169ppm As and 37.3ppm Bi. Another vein zone is located nearby but was not visited due to time and weather constraints. It is most likely that the average Au grade is along this vein is about 5ppm.
