Orsu Metals Doubles Footprint Width of Gold-Mineralized Stockwork to 250 m at Klyuchi West Zone, Sergeevskoe Gold Project,
Russia
White Rock, British Columbia (FSCwire) - Orsu Metals Corporation (TSX-V: OSU) (“Orsu” or
the “Company”) is pleased to announce additional encouraging drill results at the Klyuchi West Zone of its Sergeevskoe Gold
Project in Russia.
Highlights:
- The footprint width of gold-mineralized stockwork at Klyuchi West is now drill-confirmed to reach 250
m.
- Hole SDH17-13 intercepted:
￮ 0.58 g/t Au over 6.3 m from 9.3 m,
￮ 2.05 g/t Au over 12.5 m from 17.75 m (including 3.15 g/t Au over 6.15 m),
￮ 0.77 g/t Au over 15.35 m from 35.3 m,
￮ 1.2 g/t Au over 21.45 m from 82.9 m,
￮ 2.34 g/t Au over 2.15 m from 139.4 m,
￮ 1.48 g/t Au over 4.35 m from 156.0 m.
- Hole SDH17-14 intercepted:
￮ 1.16 g/t Au over 7.75 m from 73.65 m (including 5.23 g/t Au over 0.85 m),
￮ 0.76 g/t Au over 17.35 m from 143.3 m,
￮ 1.05 g/t Au over 5.4 m from 177.8 m.
Dr. Alexander Yakubchuk, Director of Exploration of Orsu commented: “Drillhole SDH17-13 intercepted new mineralized intervals,
not hitherto known from historical or surface trenching data at the Klyuchi West zone. Together with previously reported
drillholes, SDH17-3 and SDH17-7, and trenches, S10ZTR17-15 and S10ZTR17-16, the newly reported results identified an
approximately 250-m-wide stockwork, extending in northwestern direction to the Klyuchi West from adjacent Klyuchevskoe gold
license. Although there are still gaps in data, this more than doubles the width of the mineralized stockwork, identified in the
previously reported drillholes SDH17-3 and SDH17-7. Drillhole SDH17-14, drilled in parallel section some 60 m northwest from
SDH17-13, demonstrated that gold-mineralized stockwork further extends to the northwest and mineralization remains open downdip,
as well as across and along the strike.”
The license of the Sergeevskoe Gold Project occurs east from the Alexandrovskoe 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 drillholes SDH17-3 and SDH17-7, as well as in
surface trenches (see press release November 13, 2017). Additional Phase 2 works consisted of two drillholes SDH17-13 and
SDH17-14, totaling 414.4 m. In contrast to the previously reported drillholes, new drillholes were drilled in the opposite
direction to the northeast aiming to constrain the orientation of the already identified gold-mineralized stockwork and to test
the potential presence of additional mineralized zones.
The mineralization at Klyuchi West is limited in the south along the Shirotnyi fault (Figure 2), extending from the
Klyuchevskoe open pit. The mineralization is interpreted as a direct continuation of the stockwork shoots, extending from the
Klyuchevskoe open pit.
The mineralization is hosted by the Permian granite intrusion, which is intruded to the west by the Jurassic granodiorite
porphyry stock and Mesozoic dioritic and hybrid porphyry dykes. The stockwork consists of quartz-tourmaline-sulfide veins and
veinlets, striking to the northwest, often in parallel orientation with the dykes, as can be constrained by Orsu trenches and
drillholes.

Selection of mineralized intervals, presented below, 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.
Orsu received assays for the drillholes SDH17-13 (200 m) and SDH17-14 (214.4 m) (Table 1). Both holes were drilled to the
northeast at 60 to 70 degrees in opposite direction to the drillhole SDH17-3 and historical hole C-220, for which Orsu has no
logging and assay information except survey data and textual description in the historical reports. SDH17-13 intercepted multiple
mineralized intervals, corresponding to quartz-tourmaline veins and hydrothermal breccia, some of which correspond to those
intercepted in the drillhole SDH17-3 (Figure 3). The most significant intercepts in SDH17-13 are 0.58 g/t Au
over 6.3 m from 9.3 m, 2.05 g/t Au over 12.5 m from
17.75 m (including 3.15 g/t Au over 6.15 m), 0.77 g/t Au over
15.35 m from 35.3 m, 1.2 g/t Au over 21.45 m from
82.9 m, 2.34 g/t Au over 2.15 m from 139.4 m, and
1.48 g/t Au over 4.35 m from 156.0 m.

The style of mineralization can be best classified as intrusion-hosted gold. The closely-spaced mineralized intervals define a
250 m footprint width of gold-mineralized stockwork at Klyuchi West, including drillhole SDH17-7. The material between the
intercepts is generally grading 0.2 to 0.49 g/t Au. The stockwork requires further constraining as it has some data gaps across
the strike and downdip (Figure 3).
Figure 3. Gold mineralization in SDH17-13 and adjacent historical holes (C220) and Orsu drillholes SDH17-3
and SDH17-7 as well as in trenches S10ZTR17-7, S10ZTR17-15 and S10ZTR17-16. Note higher grade (>2 g/t Au) intercepts near the
dykes. (To view the graphic in its original size, please click here)
The intercepts in drillhole SDH17-14 (Table 2), drilled at 70 degrees towards the northeast, principally confirm extension of
the identified zones to the northwest, but lithologically they occur in the granodiorite porphyry intrusion. This drillhole was
sampled selectively over visually identified mineralized intervals, representing 65% of the drillhole length.

The available data indicate a 250x200 m potential dimension of granite-hosted stockwork within the Klyuchi West prospect of
the Sergeevskoe license, before it extends into granodiorite to the west. In the stockwork, there are four higher grade (>2
g/t Au) mineralized intervals (Figure 2 and 3), occurring approximately every 50 m across its width near the dykes. Its drill
tested vertical extent varies from 100 to 150 m and the individual veins remain open downdip below 850 to 875 mRL. Although the
data are limited some drill intercepts reveal higher gold grades than those intercepted in surface trenches.
Quality Assurance - Quality Control (“QA/QC”)
Drillcore samples were submitted directly to the ALS Limited 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.
