Orsu Intercepts 14.2m Grading 5.32 g/t Au and 59.51 g/t Ag at its Akdjol Property in Kyrgyzstan
LONDON, UNITED KINGDOM--(Marketwire - Sept. 22, 2010) - Orsu Metals Corporation ("Orsu", or the
"Company") (TSX:OSU)(AIM:OSU) is pleased to provide an update on its ongoing exploration work at the
Company's Akdjol and Tokhtazan licence areas in Kyrgyzstan (the 'Akdjol-Tokhtazan Project'). During
Orsu's 2009 and 2010 scout exploration activity on the Akdjol Prospect included grab samples, 14
trenches, and five diamond drill holes at the Akdjol Prospect. The Akdjol Prospect has been identified
by Orsu as the first ever Kyrgyz gold-silver epithermal prospect and has yielded very encouraging
assay results including:
/T/
- a vertical intercept of 14.2m @ 5.32 g/t Au and 59.51 g/t Ag, including
6.7m @ 8.69 g/t Au and 86.96 g/t Ag from diamond drilling (average
grades of 3.84 g/t Au and 49.4 g/t Ag from the four reported drill
holes);
- 784m of trenching revealing up to 36m of mineralised intercepts above
0.5g/t cutoff, and confirming a strike length of at least 700m (14
trenches); and
- Grab sample assays ranging between 1g/t and 119g/t Au and 7.7 g/t and
500g/t Ag.

2009-2010 Akdjol-Tokhtazan Exploration Programme
The field assessment of the Akdjol Prospect by Orsu in 2009 indicated that its mineralisation consists
of mineralised banded quartz veins. Grab samples collected by Orsu in 2009 returned assays ranging
between 1g/t and 119 g/t Au, with high silver grades (ranging between 7.7 g/t and 500 g/t Ag). The
Company proceeded to review the existing geological model of the entire Akdjol-Tokhtazan Project that
interpreted the previously mapped Early Permian granite porphyry bodies intruded into both the
Silurian metamorphic basement and the overlying Carboniferous clastic sequence to host, and to be a
source of, intrusion-related gold mineralization. The revision showed that the intrusives constitute
numerous sills with classic porphyry textures and may be interpreted as subvolcanic bodies of the
deeply eroded Early Permian volcanic edifice. This recognition as well as occurrence of the
mineralised veins in the Carboniferous sedimentary rocks, with some typical morphological and
mineralogical characteristics of the veins, suggests the reinterpretation of the Akdjol Prospect as an
epithermal gold-silver system rather than an intrusion-related gold system, as proposed in the
historical reports (see "Historic Resource" below).
In 2009 the Company completed 784m of trenching in 14 trenches at the Akdjol Prospect (see Figure 1).
Trenching indicated that the quartz veins at the Akdjol Prospect extend for 700m in a north-northwest
direction at a width varying from 1m to 9.3m. The veins are 6m to 10m thick, but they are enveloped by
an alteration halo with disseminated pyrite mineralisation, pinching and swelling depending on the
hosting lithologies. Both the veins and the envelope are mineralised, revealing up to 36m of
mineralised intercepts above 0.5 g/t Au cutoff. The dipole-dipole induced polarisation survey ("DD-
IP") conducted by Orsu identified a chargeability anomaly encompassing the entire 700m length of the
exposed veins. The geophysical anomaly extends for an additional 1000m south, where it is mostly
covered by overburden alluvial material over its entire length, but historical Soviet trenches
revealed mineralised intercepts some 1000m south of Akdjol. The mapping of the exposed part in
trenches recognised (Table 1) the higher grade Main Stockwork zone, which is accompanied by a lower
grade stratabound Conglomerate zone, located some 40m to 50m in the hanging wall of the Main Stockwork
zone to the west, and several veins joining these two main zones (the Diagonal zone).
Dr Alexander Yakubchuk, Director of Exploration and COO of the Company, commented: "We are very
excited to recognise Akdjol Prospect as the first ever gold-silver epithermal prospect in Kyrgyzstan.
It may represent the easternmost continuation of the prolific late Palaeozoic Chatkal-Kurama Au-Cu-Ag
porphyry-epithermal belt in adjacent Uzbekistan and Tadjikistan, where several operating gold-silver
epithermal deposits with significant mineral resources are known at Kyzylalmasai (4 Moz Au) and other
deposits in the Angren district, some 200 km west of the Akdjol Prospect. The initial drilling results
at the Akdjol Prospect reveal robust gold and silver grades, typical of gold-silver epithermal
systems, and encourage Orsu to continue further drill-testing of the upside potential in the Akdjol-
Tokhtazan licence area, focussing on strike extension of the system under cover."
Historic Resource
Gold at the Akdjol and Tokhtazan prospects was originally discovered during the exploration programme
by the USSR Ministry of Geology in the late 1970's. At the Akdjol Prospect, trenching was performed
and a 453.7m long exploration adit with crosscuts was driven approximately 100m vertically below the
outcropping mineralisation. This work identified a north-northwest-trending Au-Ag vein system, dipping
to the west at 60 degrees. Despite these generally positive results, the Akdjol Prospect was never
drilled. In the 1990's, Cameco Corporation ("Cameco") conducted exploration work at the nearby
Tokhtazan prospect, resulting in a non-JORC and non-NI43-101 compliant resource of 21.2 Mt @ 1.56 g/t
Au, containing 1.07 Moz Au (at a 0.5 g/t Au cutoff). Cameco exploration work at the Akdjol Prospect
was limited to the reassessment of Soviet exploration data, with an estimate of its non-JORC and non-
NI43-101 compliant resource of 1.481Mt @ 8.1g/t Au, containing 0.385 Moz Au within 100 vertical metres
between the adit and the surface trenches.
Further information on historical results and historical resource estimates for the Akdjol-Tokhtazan
Project can be seen in the 'Technical Report of The Gold Assets Held by Oriel Resources Plc In
Kyrgyzstan' prepared by Wardell Armstrong International Ltd, available on Orsu's website and was filed
on SEDAR (www.sedar.com) on June 28, 2006, under a company profile of Lero Gold Corp., now a wholly-
owned subsidiary of Orsu.

The trenched sample widths are considered to be a combination of horizontal and oblique width of the
outcropping mineralisation, representing 75% to 100% of the true width.
To test the true thickness and the style of mineralisation down dip, the Company completed 640m of
drilling with 5 diamond drillholes in 2010 (see Table 2). Hole AKDD10-04, drilled in the central part
of the mineralised system, returned a vertical intercept of 14.2m @ 5.32 g/t Au and 59.51 g/t Ag from
150.6 to 164.8m, including 6.7m @ 8.69 g/t Au and 86.96 g/t Ag from 151.7m to 158.4 m. Taking into
account the surface intercept of 9.3m in the trench AKTR09-05 as well as the intercepts in drill hole
AKDD10-02 and Soviet adit, occurring in the same cross-section, this drill result confirmed the
downdip continuation of the Main Stockwork veins at the Akdjol Prospect for 220m (previously 110m).
Table 2 shows assay results for mineralised drill intercepts in the central part of the Akdjol
Prospect (see Figure 1 for drill hole locations).
