Orsu Metals reports multiple gold-mineralized intercepts in drill holes and trenches at Adit 5, Sergeevskoe Gold Project, Russia

Highlights:

• Fifteen drill holes and three trenches within a 450×250 m area at Adit 5 revealed 15 northwest- to northeast-striking gold-mineralized veins
• The gold grade of mineralized intervals in drill holes at Adit 5 varies from 52 g/t Au to 3.07 g/t Au over a variable drill width of 2 to 21.8 m in primary quartz-sulfide veins, with higher grade mineralization, grading up to 6.49 g/t Au over 11.5 m, intercepted in oxidized material in trenches

Dr. Alexander Yakubchuk, Director of Exploration of Orsu commented: “Instead of finding the historically anticipated presence of 4 to 5 northwest-trending gold-quartz-sulfide veins at Adit 5, Orsu identified gold in 15 closely-spaced fan-shaped northwest to northeast-striking mineralized zones within a 450×250 m area. The vein swarms in the west and east of Adit 5 are grading on average between 0.52 g/t Au and 3.07 g/t Au over a variable drill width of 2 to 21.8 m to a depth of 100-200 m. The combined drill width of some closely spaced gold-mineralized veins, intercepted in individual drill holes varies from 4 to 61 m. In the north, mineralization at Adit 5 almost orthogonally joins the eastern part of Zone 23, therefore occurring on the southeastern flank of Zone 23. Orsu believes that gold mineralization at Adit 5 significantly expands the resource potential for the forthcoming NI43-101 estimate”.

Dr Sergey V Kurzin, Executive Chairman of Orsu, commented: “Results from the Adit 5 zone nicely complement the adjacent Zone 23 area, the backbone of the Sergeevskoe project, and will likely add to Orsu’s maiden mineral resource estimate. Our drilling contractors completed the work last week and are demobilizing now. Our geological team expects to receive all pending assays shortly and, supported by Orsu’s competent person, Wardell Armstrong International will immediately get down to work of estimating the maiden NI43-101 resource.”

The license of the Sergeevskoe Gold Project occurs immediately east from the Alexandrovskoe open pit and gold plant owned by Zapadnaya Gold Mining Ltd and to the west from the +6 Moz Klyuchevskoe gold deposit licensed to Sun Gold Mining (Figure 1)[1]. Orsu owns a 90% interest in the Sergeevskoe Gold Project (see Orsu press-release December 1, 2017).

Orsu has now received assay results for all 2018 drill holes and trenches at Adit 5. The quartz-tourmaline-sulfide veins are hosted primarily in the pre-mineral Permian granite intrusion, often controlled by the contacts of Jurassic diorite porphyry and granodiorite porphyry dykes.

The Northwestern Fault divides the Adit 5 area into western and eastern domains with dextral strike-slip sense of movement between them, interpreted based on truncation and offset of the dykes (Figure 2). Using the dykes as markers, the minimum displacement can be estimated in 100 m at least.

The orientation of the quartz-tourmaline-sulfide veins in the Adit 5 West domain is northwestern to northern, whereas in the Adit 5 East domain their strike is predominantly northeastern. Orsu identified 15 mineralized veins in each domain. Some of them may represent offset continuation of the same veins in the two domains.

Although the mineralization becomes narrow southward, it remains open in that direction and downdip. The gold-mineralized veins are widening to the north towards the eastern part of Zone 23, where veins in both Zone 23 and Adit 5 are truncated by the Shirotnyi Fault. In addition, north of the Shirotnyi fault are the gold-mineralized veins of the southern part of Klyuchi West, already reported for the drill holes SDH18-25, 26, 27, 28 (see Orsu press release July 16, 2018). Orsu drilled additional holes to test the downdip extent of mineralization, with results pending.

In Adit 5 West domain, the veins are steeply-dipping, with the westernmost veins dipping to the southwest (Figure 3). They reveal a propeller-like shape along the strike. There is increase in grade downdip even in comparison with the trenches, although in oxide is the widening of mineralized intervals, which also reveal supergene enrichment and higher gold grade.

In Adit 5 East domain, the veins are also steep (Figure 4), broadly northwest- to north-dipping. There is widening of mineralization in oxide zone, which developed down to 25-30 m from surface. In hypogene mineralization, the drilling demonstrated that the width of veins doubles at deeper levels. The mineralization remains open downdip.

The above interpretations are based on selection of the previously and newly-reported mineralized intervals, 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 a mineralized interval. Composited intervals in drill holes are presented uncapped (Table 1).

Quality Assurance – Quality Control (“QA/QC”)

Thorough QA/QC protocols are followed on the project including insertion of duplicate, blank and standard samples in all trenches. Duplicate samples were inserted after every 20 samples. All standard samples were inserted once per 20 samples. Blanks were also inserted once per 20 samples and consisted of the previously assayed barren granitoid rocks.

Drill core samples were submitted directly to the SGS Vostok laboratories in Chita, Russia, which are independent from Orsu, for sample preparation and analysis. Analysis for Au 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.
