Orsu Metals Corporation announced the results of an updated Mineral Resource estimate for its Sergeevskoe Gold Project in Zabaikalsky Krai, Russia. An Inferred Mineral Resource was estimated for a large stockwork, containing 179 segments of sheeted subparallel quartz-tourmaline-sulfide veins in nine domains over a strike length of 2x1 km. The individual vein segments are separated by faults along the strike or unmineralized intervals across the strike. The mineralized envelope is divided by the Shirotnyi Fault into two areas with largely northwest-trending stockworks in the Peak Klyuchi, Kozie West, and Klyuchi West domains (to the north of the fault) and west- to southwest-trending stockworks in Zone 23 West, Zone 23 Middle, Zone 23 East, and Adit 5 West and East domains (to the south). Based on 2019 exploration results, the veins in all domains were reshaped to greater or smaller extent. Exploration works at Peak Klyuchi yielded a swarm of new veins. After additional trenching, veins in Zone 23 West domain were reinterpreted to strike southwest. New veins were discovered at Kozie West. All veins between the Northeast Fault and Shirotnyi Fault are now interpreted to belong to a single domain of Klyuchi West. In Zone 23 East domain, previously constrained veins were discovered to continue downdip to a depth of 400 m. Several veins were discovered in the western part of Adit 5 West. From these domains, an Inferred Mineral Resource of 30.42 million tonnes, grading 1.45 g/t gold and containing 1.417 Moz gold at a 0.5 g/t gold cut-off grade and using a gold price of USD 1,450 per Troy ounce was optimized into a pit constrained by the license boundaries to the east and southwest. The result was a 19.3% increase to the maiden Mineral resource estimate.
