Geology

Mineralization is related to wolframite bearing hydrothermal quartz veins which occur along thrust zones of the “TsagaanGol” granite massive. The country rocks are Upper Cambrian to Lower Devonian siltstones and sandstones, which were intruded by the granite suite (plagiogranite, granodiorite, quartz diorite). The deposit is located between the Altai and Tolbo Lake deep faults which belong to the Mongolian-Altai fold belt as part of the Mongolian-Altai metallogenic province. A total of 23 ore bearing zones have been discovered so far. The largest ore bodies are 450 m (vein # 22), 1 km (veins # 13 and 22) and 2 km (vein # 19) long and 0.1 to 1.0 m thick. Further veins generally are less than 250 m long and 0.1 to 0.5 m thick. The main veins are shallowly dipping to the NE (20-35°) and can be followed to a depth of up to 280 m.

Historically, elevated gold grades between 0.2 and 6.0 ppm in single samples have been reported, one sample contained 94 ppm gold. In 2013 we did total of 2150 meter drilling work to check the early drilling results and do exploration on early mining zones. Historic reserve estimates came up with 32,668 t ore (C2) at 19.26 % WO3 (6,206 t W metal) and 14,788 t ore (P2) at 14.44 % WO3 (2,135 t W metal). The average grades varied between 5.1 and 30.6 % WO3. Considering that cut-off grades of 3.3 % WO3 for C2 resource calculations and 2.65 % WO3 for P1 resource calculations were used, resources under the current economic situation would have been much higher. The grade of the concentrate is 65.9 to 71.3 % WO3 and the metal recovery grade for wolframite is 90.9 %. “Khovd River” deposit is probably the world highest-grade wolframite mine. According to latest exploration results by SS Mongolia, the resource estimated as 11000 t of WO3 there also seems to be the potential for discovering new veins in the area and its shows HIGH potential for increasing resource.
