Orlovsky is an active underground mine exploiting a large, polymetallic, high grade, and gold rich VMS deposit. It comprises the Main Orebody, which comprises an upper and lower part with an irregular pod-like shape, 20° to 30° dip to the SW, average thickness of 35m and down-dip extent of 600 m. It is now almost worked out, with the remaining resources consisting of remnant blocks distributed in the lower part of the orebody and representing some 25% of the whole deposit. A 0.85 Mt oxidised cap on the upper part of the orebody has been excluded from the resources since until now, no technology has been successfully developed to treat it.

350 m to the SW of the lower part of the Main Orebody is the New Orebody comprising a southern portion with a 10° to 15° dip to the SW and thickness of up to 56m and a northern portion with very high grade and thickness of 5-20 m. The combined New Orebody occupies a surface area in long section of some 250 m by 150 m and accounts for the rest of the resources in the deposit.

Due to the relatively flat nature of the ore, mechanised drift and fill is the mining method used. Shaft hoisting of ore is used. A rudimentary figure provided in the IPO indicates that mining has been concentrated above 500 m depth prior to 2011 but is now focused on resources up to 1000 m in depth.

Production from Orlovsky over the remaining life of the mine is expected to be at or below current output, as mining takes place in deeper horizons and more challenging geological conditions.
