26 4 - Independent Geological Report - Mongolia 2.0 GEOTECTONIC SETTING AND REGIONAL GEOLOGY Mongolia is situated at the margin of two cratonal blocks; the North China Platform to the south and the Siberian Craton to the north. The region has experienced major terrain accretion events throughout the Paleozoic, with subsequent postcollisional extension giving rise in the Paleozoic to extensive bi-modal volcanism and associated intrusion of felsic, calc-alkaline plutons and stocks (Cunningham, 2007 and Parfenov et al., 2007). Carboniferous sedimentary deposits are known to be coal bearing and occur in the south Gobi and northwestern Mongolia, with the northwestern coal basin extending north into Russia (Sanjsuren, 2008). The geology of northwestern Mongolia is dominated by events related to the closure of the Tethys Ocean during the Late Paleozoic to Early Mesozoic (Parfenov et al., 2007) (Figure 2). The resulting suture zone, the Mongol-Okhotsk Zone (MOZ), strikes eastnortheast over approximately 3000 kilometres and 45 ° 50 ° = Khuden Khuden (Coal) (Coal) (Coal) Bayan-Olgii 90 ° 95 ° 90 ° UVS UVS UVS UVS NUUR NUUR NUUR NUUR NUUR NUUR NUUR NUUR NUUR BASIN BASIN PROJECTS PROJECTS Ulaangom Uvs Khovd Zavkhan Khovsgol KHANGAI KHANGAI KHANGAI KHANGAI KHANGAI KHANGAI KHANGAI FAULT FAULT PROJECTS PROJECTS Uliastai Arkhangai Govi-Altai 95 ° Mine/Major deposit (Commodity) Town Capital Bayankhongor Nariin Nariin Nariin Nariin Nariin Nariin Sukhait Sukhait Sukhait Sukhait Sukhait Sukhait Sukhait Sukhait Sukhait Sukhait (Coal) (Coal) (Coal) (Coal) (Coal) (Coal) (Coal) (Coal) (Coal) (Coal) Moron Bulgan Erdenet Erdenet Erdenet (Cu) (Cu) Ovorkhangai M O N G O L I A Lake 100 ° 100 ° Railroad GCC Licence/Application Tavan Tavan Tavan Tavan Tolgoi Tolgoi Tolgoi Tolgoi (Coal) (Coal) Omnigov is recognised as being over 200 kilometres wide (Koval, 1999). Units are down faulted to the north and the MOZ is inferred as having a sinistral strikeslip component. Numerous mafic and ultramafic hosted copper-nickel-PGE deposits and prospects and copper bearing porphyry deposits and prospects occur along the length of the MOZ, with the majority of known deposits occurring in Russia. Such deposits are typically spatially and temporally associated with Mesozoic intrusions (Parfenov et al., 2007). During the Cenozoic, Mongolia experienced an extended period of quiescence and the development of a large erosion surface (Cunningham, 2007). Cenozoic sedimentary deposits are common across Mongolia and fill basin-and-range physiography typical of the region. 105 ° Irkutsk R U S S I A Selenge = ULAANBAATAR ULAANBAATAR Tov Boroo Boroo Boroo (Au) (Au) Dundgov Tsagaan Tsagaan Tsagaan Tsagaan Tsagaan Tsagaan Tsagaan Tsagaan Tsagaan Suvarga Suvarga Suvarga Suvarga Suvarga (Cu) (Cu) (Cu) (Cu) (Cu) (Cu) (Cu) (Cu) (Cu) (Cu) Dornogov (Cu) 105 ° 110 ° Oyu Oyu Tolgoi Tolgoi Tolgoi Tolgoi Tolgoi Tolgoi (Cu-Au) (Cu-Au) Khentii 110 ° Chita Dornod Sukhbaatar 115 ° 120 ° C H I N A 115 ° 120 ° % 0 500 km Figure 1: Location of GCC licences and applications, Mongolia 50 ° 45 °

The main targets for exploration in the Khondlon and Buiit licences are potash and soda ash in a large Cretaceous sedimentary basin, with the remainder of licences being prospective for orthomagmatic nickel-copper-(PGE) and porphyry copper- (gold) deposits spatially related to the MOZ. 3.1 POTASH DEPOSITS Potash deposits occur in almost all geological systems and are most commonly found in rocks of Devonian, Carbonifeorus, Permian, Cretaceous and Tertiary age. Although distributed globally, the majority of economic potash deposits are located in the northern hemisphere. The following is summarised from Rauche et al., 2009. The majority of potash deposits are of marine origin, where bodies of seawater become isolated by tectonic activity and/or sea level changes. Such isolated bodies become concentrated through evaporation with eventual salt crystallisation.

Numbers in legend indicate terrane name (modified from Badarch, 2002) % compounds are deposited first through sedimentation, with the most soluble compounds being the last. A complete evaporation/salt deposition cycle begins with basic carbonates (limestone, dolomite, and sometimes magnesite), followed by sulfates (gypsum and anhydrite), rock salt, and finally potassium and magnesium salts. Intermediate layers of clay are deposited by repeated influxes of fresh water, which can lead to partial redissolution of the salt deposits. Eolian transportation of fine grained clastics into the basin can occur. This process can occur several times in a basin, resulting in repeated evaporation cycles. Potash deposits are also known to form in saline lake environments in graben/rift zones (Figure 3 next page). Hydrothermal brines are a major source and controlling factor in such environments, however “cold” conditions, assuming an equivalent mineral source and intensive fluid circulation, can also provide suitable environments for potash deposition.
