The reserves and resources of the deposit, amounted to 63 tons, with an average gold grade in ore bodies of 2.4 g/t and about 280 t of silver (10.7 g/t). Since the end of 2009, the field has been developed, with ~4.0 t of gold being mined in 2019, about 2.3 t from open pit and 1.7 t from an underground mine, with average grades of 1.4(open pit) and 10.6 g/t (underground). The main ore-bearing zone of the Birkachan deposit extends for 4.5 km and is 200–300 m wide. It consists of several northeast-trending vein zones arranged in an echelon shape, falling to the southeast at angles of 55°–70°.
