Systematic geological investigations in the Qosha
ore area began in 1966, when reconnaissance surveys at a scale of 1:50,000 were
conducted between the Aghstafachay and Zayamchay river valleys. These initial
studies led to the discovery of the Qosha gold deposit. Subsequent detailed
exploration campaigns refined the geological framework of the deposit and
resulted in the identification of 19 gold-bearing zones. From 2005 onward,
Azerbaijan International Mining Company Limited carried out phased and
comprehensive geological exploration, culminating in the commencement of commercial
extraction in 2014. Scientific evaluations conducted by the company confirmed
that the deposit belongs to the high-sulfidation epithermal genetic type. The
geological characteristics of the system were investigated through an
integrated analysis of hydrothermal alteration patterns, ore paragenesis, and
the lithogeochemical properties of magmatic rocks that reflect the nature and
origin of the hydrothermal fluids responsible for ore formation.
