Abstract

Surface geological and trench surveys and drilling exploration (total length, 1,100 m; 9 drill holes) were carried out to secure new Au ore bodies in the area(0.96 km2) of Actosity gold field, where is located at the western Kuldjuktau mineralized district in the middle territory of Uzbekistan. Several Au ore bodies occurring as tabular or lens shapes with thickness of 0.5~35 m were newly discovered on the outcrops and extended to N40~70° W direction with dipping of 70~90° SW or NE. Indicated ore resource of gold with Au grade of 0.25~3.52 mg/kg was newly estimated by 2,382 t(gold resource of 2.5 t) as a result of 9 drilling exploration in 2010~2012 from the Actosity gold field. Judging from the ore resources and Au grade of the Actosity gold field, economic potentiality of mining development seems to be low. Because of high possibility to secure new ore resources through more detailed exploration works from the Actosity area, the growth of econonic value will be expected by a mine of middle scale.
