Orsu Metals Corporation reported results of its complex assessment of recently received assay results of the 2021 geochemical survey. Four of seven >0.1 ppm Au geochemical anomalies reported previously revealed consistent clustered values in excess of 0.05% copper in 217 received assays (8.8%). In 44 samples (1.75%), the copper values exceeded 0.1%, with maximum value of 0.32% Cu. The samples with >0.05% Cu values form three groups of anomalies in the centre (Surprise), west (Dalnee and Ust-Borovoe), and south (Sergeeva) of the Sergeevskoe license area. The Surprise anomaly in the centre of the license area, measuring 1000x650 m, occurs approximately 1 km northwest from the Peak Klyuchi resource domain, but it is elongated to the northeast. The Surprise anomaly returned 107 assays exceeding 0.05% Cu in four adjacent traverses. In 26 assays, the copper values are more than 0.1%, with maximum value of 0.29% Cu. This anomaly also shows elevated molybdenum values up to 227 ppm and consistent >0.1 ppm Au values (0.89 ppm Au maximum). The geochemical anomaly coincides with moderate magnetic high. Diorite porphyry dikes were historically identified, but not consistently traced near the Surprise anomaly. Several >0.05% Cu values form linear clusters trending farther to the southwest and west over 0.5 to 1.5 km strike length towards Dalnee and Ust-Borovoe anomalies. At the Ust-Borovoe and Dalnee anomalies, 22 samples returned >0.05% Cu values. The largest anomaly of 12 samples over 400x100 m area forms a more coherent northeast-trending cluster with up to 0.15% Cu and 0.36 ppm Au at the northwestern contact of the minor granodiorite porphyry intrusion. The 1100x250 m Sergeeva anomaly is based on 55 samples with >0.05% Cu values collected on 11 adjacent lines. This anomaly has maximum values of 0.32% Cu and 0.74 ppm Au. It has no anomalous molybdenum values. The anomaly coincides with the historically mapped WNW-trending dyke swarm and magnetic low. The three groups of complex Au-Cu-(+/-Mo) anomalies are identified by Orsu for the first time in exploration history of the Sergeevskoe and Klyuchevskoe deposits. They were never drilled or trenched. However, Orsu revised its holes drilled in 2017-2018 in the north of the Klyuchi West resource domain. Some of them were assayed by the Company for copper and other elements due to presence of visually identified copper minerals during core logging. These holes intercepted an intense northwest-trending quartz stockwork and related alteration, similar to observed in porphyry systems. The following holes have intercepts with assayed copper values: Hole SDH18-35 - 0.16% Cu, 1.34 g/t Au, and 3.94 g/t Ag over 53.8 m from 84.1 m depth; Hole SDH17-13 nearby - 0.13% Cu, 0.57 g/t Au and 2.18 g/t Ag over 33.95 m from 37.65 m and 0.13% Cu, 1.1 g/t Au, and 2.72 g/t Ag over 26.55 m from 78.8 m depth; Hole SDH17-3 - 0.32% Cu, 0.81 g/t Au, and 7.3 g/t Ag over 7.7 m from 17.4 m depth and 0.38% Cu, 2.99 g/t Au, 14.8 g/t Ag, and 0.026% Mo over 7.6 m from 126.45 m depth; Trench S10ZTR17-7 - 0.2% Cu, 15.49 g/t Au, and 7.53 g/t Ag over 7.3 m. Interpreting the geochemical and drilling data, Orsu concluded that a 5-km-long arcuate Cu-Au-Mo trend extends from the northern part of Klyuchi West towards the Surprise and then to the Ust-Borovoe anomaly. The Karmaevskoe veins are interpreted to be peripheral and also related to this trend. On the other hand, Sergeeva anomaly without molybdenum is either a continuation of the Zone 23 resource domain or may form a separate mineral cluster. In the 1960s, a north-south fence of 20 holes was drilled across the present Sergeevskoe license area. Coincidentally, only three holes in the middle of the drill fence intercepted some gold. None of them was assayed for copper, and the entire drill fence overall missed the Cu-Au-Mo soil anomalies identified by Orsu.
