Prospect assessment of the Amur River Province gold mining centers

Abstract. The paper provides data on three historical gold mining centers in the Amur River gold-bearing province: Solovyovsk, Gonzha, and Tokur. Since 1890, 365 tons of gold have been mined from the gold mining center deposits. They are located at the junction of the Aldan-Stanovoy, Mongol-Okhotsk, and Amur geoblocks separated by the North Tukuringra and South Tukuringra regional faults. The gold mining centers appear to differ in their geological structure, gold mining levels, and the number of gold ore deposits of different formations. In the Solovyovsk center, the main prospects prove to be associated with discovering Carlin-type gold-polymetallic, gold-sulfide-quartz, and gold-mercury formations, as well as bulk stockwork gold deposits in the Archean greenstone units. The Gonzha gold mining center prospects pertain to new gold-silver deposits (such as Pokrovsk), gold-sulfide-quartz ones similar to Pioneer, and gold-copper-molybdenum-porphyry ones (Ikan, Vostochnoye Dvoynoye). The Tokur center is expected to identify new deposits of gold-quartz, such as Tokur and Albyn, and gold-sulfide (Malomyr) formations. The analyzed gold potential of the ore centers determines further prospects for mining ore gold in each of them, including discovery of new large deposits.
