Shambesai and Obdilla Gold Deposits Exploration and the Regional Potential of the Southern Kyrgyz Tien Shan
Manas’ Shambesai (697,000 Oz Au) and Obdilla (485,000 Oz Au) gold deposits were discovered by the company in 2007 and 2005 respectively. Manas currently holds an exploration lisence portfolio of 3,397 km2 through Southern Kyrgyzstan’s Tien Shan Range.
Both Shambesai and Obdilla are open at depth. Future resource delineation will focus on higher grade zones that have the potential to support an underground or expanded open pit design.
Shambesai and Obdilla display Carlin Type characteristics. Carlin deposits occur within trends or districts and we believe there is every possibility that the same will be true in this region for several reasons:
- - The stratigraphic contact that hosts Obdilla and Shambesai outcrops locally for a total of 50km;
- - The host stratigraphy and those equivalent to it occur throughout the Turkestan-Alai and Southern Fergana Segment across some 300km;
- - The Hg-Sb deposit, to which Obdilla and Shambesai are close to, is but one of a trend of proven Hg-Sb and Sb deposits that extend across 160km.
Further reason for the high prospectivity is that, while Soviet period exploration was extensive in the region, their focus was on industrial metals and heavy-concentrate sampling was favored. Assay methods that could identify disseminated sub-micron Au were at the time were also prohibitively expensive, inaccurate and so rarely used. As no coarse gold exists in the Obdilla and Shambesai deposits they deposits, and no doubt others, remained undiscovered.
