The Khongor copper-gold-molybdenum prospect is located 900 km to southwest from the Ulaanbaatar city, on the territory of Shinejinst and Bayan-Undur countries of Bayankhongor province. The provincial center, Bayankhongor town is located 280 km to northeast from the prospect area. The Khongor copper-gold-molybdenum prospect consists of two main exploration license areas, as Khongor and Khongor - 1. The Khongor - 1 exploration license area is representing main part of the prospect area with total 70012 hectare, approximately 30 km by 10-15km. The Khongor exploration license relative smaller with total 5045 hectare area, approximately 3.0km by 1.5km, locating on northwestern extension of the main exploration license area.
Usually, two stages of ancient mining activity known in the Khongor prospect region. The earlier stage of mining activity was developed during Bronze Age. The second stage is related to end of the 19th century and early 20th century, which was named “old Chinese workings”. These ancient mining activities are represented by dominantly small hand mining open pits and mining dumps on the recent surface. Probably massive turquoise (as jewelry), high grade copper oxide ore, native copper and placer gold were mined from these open pits. Several small hand mining open pits and dumps exist at the Nomin Tal copper occurrence, locating 5km to southwest from the Khongor prospect. Also, numerous old workings to be observed on northern slope of the Edrengin Nuruu mountain range, locating 30-40km to SW from the our prospect area, where was mined gold nuggets from the Cretaceous conglomerate.
The prospect region was covered by systematic geological studies, as 1:1 000 000 scale geological and 1:500 000 scale geological and hydrogeological mapping and prospecting in period 1951-1976. In 1964-1965, Russian geologists Uflyand A.K, Filipova I.B. and Chehovich M.B. were carried out 1:1 000 000 scale geological mapping and prospecting in this region, which is occupying large areas to east and north of the Khongor prospect. Western part of the Khongor prospect region was covered by 1: 500 000 scale geological and hydrogeological survey in 1951-1952 (Boyahonin V.S. and others), while eastern part of this region was covered by 1: 500 000 scale geological and hydrogeological survey in 1972-1973 (Stepanov A.N. and others). Whole region was covered by 1: 500 000 scale geological mapping and prospecting in 1983-1985 (Borzakovski Yu.A and others). During these investigations, regional geological structure of the Khongor prospect region was clarified and several mineral ore showings and geochemical anomalies were identified in this region.
More detailed geological mapping and prospecting of the prospect region was started in 1986. In period 1986-2003, this region was covered by 1:200 000 scale geological mapping and prospecting by Russian, Mongolian and Czech geologists. During these geological studies, the geological structure of the region was clarified in detail and several hydrothermal-metasomatic altered and mineralization zones, mineral occurrences, ore showings, geochemical anomalies were identified in this region. In 1986, 1:200 000 scale geological mapping and prospecting was carried out by Russian and Mongolian geologists (Zabotkin L.B and others) on NE extension of the Khongor prospect.
The territory to north of the recent Zuun Mod porphyry molybdenum-copper deposit and to east of the Khongor prospect was covered by SW corner of this mapping and prospecting program. During this program, the Khuvin Khar copper occurrence was identified in the big granite intrusion, which is locating on license area of the recent Erdene Mongol company. SE corner of the Khongor prospect and the Zuun Mod porphyry molybdenum-copper deposit region was covered by 1:200 000 scale geological mapping and prospecting in 1996-1998 (Bukhbat S and others), whom was identified firstly the Zuun Mod molybdenum-copper mineralization zones (1996). Northern main part of the Khongor prospect (almost 70% of the prospect) was covered by 1:200 000 scale geological mapping and prospecting in 2003 (Gansukh D. and others). They are identified several copper, zinc, lead and gold ore showings and geochemical anomalies on the Khongor prospect. The Czech and Mongolian geologists carried out 1:200 000 scale geological mapping and prospecting on southern part of the Khongor prospect.
The prospect region is well endowed with mineral resources and mineral potential. The previous explorers have indicated deposits and occurrences of molybdenum, gold, copper, lead, zinc and coal. Only mine in this region is Khotgor hard coal open pit mine for local consumption, locating 60 km to NE from the prospect area, 7km to west from the Shinejinst town. Also several other hard and brown coal occurrences are known in this region. These coal prospects are owned by Canadian Gobi Coal company.
At the recent stage, the Zuun Mod porphyry molybdenum-copper and White Hill copper-zinc VMS deposits present possible economic potential deposits of the region. The Zuun Mod deposit is locating 20 km to east from the Khongor prospect. Owner of the Zuun Mod Mo-Cu porphyry deposit is Canadian Erdene Mongol company, which owns several other exploration licences in this region. They are carrying active exploration program on the Nomin tal copper and Altan Nar gold occurrences, locating just few kilometer SW from the Khongor prospect.
Main mineralized porphyry intrusive rock of the deposit is represented by Late Permian - Early Jurassic granite porphyry stocks with rarely unidirectional solidification texture (UST). UST is one of the important texture of the mineralized porphyry intrusions (“exploration guide”), which is form on the apical part of the intrusive body. Few other copper targets are locating on surrounding areas of the Khongor prospect, which owned by also Erdene Mongol LLC. The Khuvin Khar Cu occurrence is locating just few kilometers to east from the prospect, while Nomin Tal Cu and Altan Nar Au occurrences 5km to west from the prospect. All these occurrences tested by surface exploration and limited drilling program. The Khul Morit porphyry copper deposit is locating 35km to SW from the Khongor prospect, which owned by Mongolian Gobi Exploration company. They are carrying out active exploration program by trenching and drilling. The porphyry copper mineralization was formed in the Carboniferous monzonite porphyry intrusion, associated with quartz-tourmaline breccia pipe. The White Hill Cu-Zn VMS deposit is locating 100 km to NE from the Khongor prospect, which owned by Universal Copper Corp. Several other VMS occurrences, Oortsog, Bayangobi-1 and Bayangobi-2 hardrock Au occurrences are locating in this region. The Khondloi, Dukhum and Khalzan Bulag group Cu occurrences are locating 10-25 km to SW and west from the White Hill deposit. The Khul Morit porphyry Cu deposit is locating 35 km to SW from the Khongor prospect, which owned by Mongolian Gobi Exploration company. Today, this region is a one of the most important exploration area, especially to identify porphyry copper, gold, molybdenum deposits.
By the metallogenic classification of the country, the prospect region belongs to the Zuun Mod copper-molybdenum ore region of the Gobi-Altay metallogenic belt in the South Mongolian metallogenic province. The Gobi-Altay metallogenic belt presents one of the high potential area of the country to identify economic type of porphyry copper, copper-molybdenum and copper-gold mineralization. So the Khongor prospect region is highly potential to identify for economic type of porphyry copper, molybdenum-copper, copper-gold mineralization, because all geological formations and structures of the Zuun Mod porphyry molybdenum-copper and Khul Morit porphyry copper deposits continue on the Khongor prospect. By the recent study, the metallogenic belt also has good potentiality for copper-zinc massive sulphide type of mineralization, which is formed in the paleo oceanic floor by influence of hydrothermal-metasomatic process. The White Hill copper-zinc VMS deposit and several other occurrences are locating 100km to NE from the Khongor prospect. The nearest coal mine from the prospect is Khotgor hard coal mine, locating 60 km to NE from the prospect, 7 km to west from the Shinejinst town. The deposit was explored by Mongolian geologists in 1977-1978. Total 22 vertical drill holes were drilled in that time. Recently, the deposit and surrounding areas owned by Canadian Gobi Coal company. They are carrying active exploration program in this region.
