Orsu Metals recent drilling connects Kozie and Klyuchi West occurrences into a single 750-m-long and 250-m-wide stockwork at its Sergeevskoe Gold Project, Russia
Orsu Metals Corporation (TSX-V: OSU) (“Orsu” or the “Company”) is pleased to announce additional trenching and drill results at its Sergeevskoe Gold Project in Russia.
- Assay results from extended 2018 drill programme confirm that Klyuchi West and Kozie are parts of a single 250-m-wide gold-mineralized stockwork, extending for 750 m
- The best intervals returned:
- 6.86 g/t Au over 17.5 m from 103.8 m (including 35.15 g/t Au over 1.8 m and 20.8 g/t Au over 1.2 m) in trench STR18-32,
- 3.34 g/t Au over 4.6 m from 160.3 m in trench STR18-32,
- 1.82 g/t Au over 9.7 m from 189.9 m in drillhole SDH18-76,
- 2.77 g/t Au over 7.0 m from 139.45 m in drillhole SDH18-78,
- 1.77 g/t Au over 4.6 m from 270.05 m in drillhole SDH18-78,
- 2.18 g/t Au over 10.45 m from 14.55 m in drillhole SDH18-58.
Dr. Alexander Yakubchuk, Director of Exploration of Orsu commented: “Assays for samples from the most recently drilled holes and trenches clearly link the previously-reported multiple mineralized zones of Klyuchi West and Kozie occurrences into a single 750-m-long and 250-m-wide gold-mineralized cluster, occurring to the northwest of gold mineralization in the nearby Klyuchevskoe open pit. Some intercepts, especially in trench STR18-32, returned outstanding gold grades”.
Dr. Sergey Kurzin, the Executive Chairman of the Company, noted: “Congratulations go to the exploration team of Orsu. While Kozie was known before, Klyuchi West is a brand new discovery by Orsu. Now the exploration team has been able to demonstrate that both occurrences form a single system. Along with Zone 23 and Adit 5, this stockwork will be a major building block of the maiden 43-101 compliant resource to be announced shortly.”
The license of the Sergeevskoe Gold Project occurs east from the Aleksandrovskoe open pit and gold plant owned by Zapadnaya Gold Mining Ltd and immediately to the west from the Klyuchevskoe gold license owned by Sun Gold Mining (Figure 1). The Klyuchevskoe (Klyuchi) gold deposit represents a +6 Moz gold endowment (see Orsu press-release dated September 21, 2016). Orsu owns a 90% interest in the Sergeevskoe Gold Project (see press release dated November 6, 2017).

At Klyuchi West, the Company previously reported encouraging intercepts in surface trenches and drillholes (see press releases November 13, 2017; January 25, 2018; and August 8, 2018).
As part of the completed extended 2018 exploration program, Orsu received assays for trench STR18-32 and drillholes SDH18-71, SDH18-76, SDH18-77, SDH18-78, SDH18-79, SDH18-80, SDH18-57 and SDH18-58 in between the Klyuchi West and Kozie occurrences (Table 1). The mineralized corridor, discovered by Orsu at Klyuchi West, is now 250-m-wide (Figure 2), extending directly from the Klyuchevskoe open pit. When mineralization is hosted in Permian granite, it consists of closely-spaced and steeply-dipping linear quartz veins and veinlets traced to a depth of 300 m, whereas it consists of chaotically oriented veinlets in the Jurassic granodiorite porphyry stock near the contact with granite. Further northwest, the mineralization occurs along more linear veins. It can be traced towards the Kozie prospect, where mineralization is controlled by a contact between Jurassic granodiorite porphyry and magmatic breccia.
The overall confirmed strike length of the 250-m-wide stockwork is 750 m. It remains unconstrained to the west and northwest. The area in between Kozie and Klyuchi West was never trenched or drilled in the past. It coincides with a low resistivity anomaly, identified by Orsu in 2017 during the PD-IP electric surveying.

The mineralization and lithological varieties are constrained mostly by 2017 and 2018 Orsu trench and drill data data. Mineralization south of Shirotnyi Fault is not shown.
Selection of mineralized intervals, presented below (Table 1), is based on a 0.5 g/t Au cut-off for compositing, with maximum 2 m length of 0.3-0.5 g/t Au mineralization included into mineralized interval. Composited intervals in drillholes are presented uncapped.

Quality Assurance - Quality Control (“QA/QC”)
Drillcore and channel samples were submitted directly to the SGS Vostok and ALS Limited laboratories in Chita, Russia, which are independent from Orsu, for sample preparation and analysis. Analysis for gold is performed using fire assay method with atomic absorption (“AA”) finish and with a gravimetric finish for samples exceeding 10 g/t Au. Results published are from the gravimetric finish if above 10 g/t Au and from the AA finish if lower than 10 g/t Au.
