Currently, Western Uzbekistan is considered as one of the most promising for gold, silver, tungsten, tin, mercury, antimony, lead-zinc, uranium and other minerals in the Central Asian ore province. Problems of geology, formation conditions and distribution patterns of mineralization were covered in the works of many researchers. The work describes the genetic types and conditions for the localization of mineralization - individual deposits and ore occurrences. Also, the indicated mineralized zones, the conditions of occurrence of the mineralization, the geological-structural position and the peculiarities of the host complexes. Descriptions of promising tungsten, tin ore, polymetallic, mercury and other ore zones, which serve as a reserve in expanding the resource base in the Republic, are given. Tungsten, tin ore, and mercury mineralizations are characterized in more detaisl, since the latter in the region under study is often spatially associated with gold and forms of mercury-antimony-polymetallic mineralization.

In the Zirabulak Mountains, gold mineralization is localized mainly among the limestones of the Sapenskaya suite of the Lower-Middle Devonian, in the shales of the Altyaulskaya suite of the Middle-Upper Ordovician, in the sandy-shale sediments of the Silurian, in the granites of the Karnab intrusive massif.

Industrial tungsten deposits are concentrated within Western Uzbekistan. Within the study area, significant accumulations of tungsten mineralization are concentrated in skarn zones and ore formation is associated with skarn formation.

In the region of tin ore deposits proper, only a few are known, but tin is sometimes present in noticeable quantities in tungsten deposits and forms a general wide scattering background in various types of intrusive as well as postmagmatic altered rocks.

Deposits of lead-antimony ores from hydrothermal solutions occurred at the junctions of ruptures with gently dipping cracks in the soda part of the anticlinal structure.

A number of cinnabar ore occurrences have been identified within the southeastern end of the republic. The most favorable ore-bearing rocks are dolomites, dolomite limestones and limestones. The main ore mineral is cinnabar.
