Minerals
The district contains several copper-polymetallic, copper-porphyry and stratified sulphuric pyrite deposits and ore manifestations. Some of deposits of the Merisi minign district is represented mainly with chalcopyrite and with subordinate lead-zinc deposits with minor copper. The second order minerals are marcasite, hematite, malachite, azurite, native gold and silver. The modern exploration data demonstrate commercial gold presence in quartz-sericite-chlorite and quartz-alunite rocks in close vicinity to the hydrothermal polymetallic veins. The central part of the mining district is occupied by outcrops of the Merisi-Namonastrevi-Chalati subalkaline diorite-syenite-monzonite complex, which is surrounded by huge halos of gold-bearing hydrothermally altered rocks.
