Orsu Provides Update on Mineral Exploration Projects

LONDON, UNITED KINGDOM--(Marketwire - May 13, 2009) - Orsu Metals Corporation ("Orsu", or the "Company") (TSX:OSU)(AIM:OSU) is pleased to provide an update of on-going work at the Talas and Tokhtazan exploration licence areas of north west Kyrgyzstan and the Karchiga exploration area of north east Kazakhstan.

Talas Update

The Talas exploration licence area comprises the Taldybulak-Talas, Barkol, Kentash and Korgontash areas.

The previously announced 2008 / 2009 drilling programme to better delineate the extent and geometry at Taldybulak Central and assess the additional tonnage potential through the testing of peripheral targets of the central high grade core is underway. An overall exploration expenditure of CAD$7.8 million is budgeted for the Talas Project in 2009, all of which will be covered by Gold Fields Orogen Holdings BVI Limited ("Gold Fields").

To the end of April 2009, a total of 12,291m have been drilled, representing 72% of the initially planned 17,000m drill programme. A total of 10,168 samples have been delivered to the Alex Stewart laboratory, (Karabalta, Kyrgyzstan) for elemental analysis, of which 9,861 assay results, or 97% of submitted samples have been received. The results in Table 1 confirm that the Taldybulak-Talas prospect contains broad and coherent copper-gold porphyry mineralisation at above-average gold grades for this style of mineralisation.

Tokhtazan Update

The Tokhtazan exploration licence area comprises the Akdjol and Tokhtazan licences.

Within the 2008 / 2009 exploration programme, works undertaken within the Tokhtazan licence included 1,540 metres cubed of trenching and road cutting, with 640 samples being collected. In addition, a 642.5m reverse circulation ("RC") and diamond drilling programme was completed.

Table 2 shows assay results from core and RC drilling which confirm the presence of the previously interpreted mineralised structure. Orsu intends to carry out further investigative drilling during the 2009 / 2010 exploration season.

Akdjol Project

The Company also performed 3,140 metres cubed of trenching and road cut sampling, with some 2,532 samples collected. In 2008, the works were focused on the Bulderek occurrence located 3.5 km south-southwest from the Tokhtazan licence. The works included prospecting, trenching and geophysical exploration:

- dipole dipole induced polarisation ("DD-IP") (interval: 50m, depth: 200m, total: 12.8km);

- magnetic survey (interval: 25m, total: 41.45km);

- gamma-ray spectrometry (interval: 25m, total: 43.3km).

The 2008 works identified a previously unknown Cu-Au anomalous zone. Table 3 shows assay results received for the 2008 channel sampling.

Based on current geological observations, the trenched sample widths are
considered to be representative of the true width of the outcropping
mineralisation, although the true thickness of the mineralisation down dip
is yet to be confirmed.


Karchiga Update

The primary scope of the 2008 / 2009 programme is designed to upgrade the previously reported mineral resource estimate at the Karchiga project to Measured and Indicated categories under National Instrument 43-101. This work will be based on drilling, geophysical and geochemical works completed as part of the 2008 exploration programme focused on the Central and North East lodes of Karchiga.

The total drilling programme consisted of 10,599.8m, of which 9,804.7m was drilled at Karchiga's Central and North East lodes, with an additional 795m completed to test new exploration targets. All samples have now been submitted to the Alex Stewart laboratory, Kyrgyzstan and after receipt of the final assay results, Orsu will, in due course, provide an update.

Notes to Editors:

1. For avoidance of confusion;

- The Taldybulak copper-gold porphyry prospect within the Taldybulak exploration licence area is a separate asset from the Taldybulak Levoberezhny gold deposit previously owned by Central Asia Gold Limited, and

- The Talas Copper Gold Limited Liability Company, holder of the Taldybulak licence, is a separate company from Talas Gold Mining Company, which was the owner of the Jerooy Gold Project.

2. Orsu Metals Corporation operates a stringent QA/QC policy that includes external certified standard samples and blanks in each individual batch sent for analysis. Further information on the Taldybulak-Talas, Akdjol and Karchiga projects is included in the technical report entitled "Technical Report on the Exploration Licences Held by Lero Gold Corporation in Kyrgyzstan & Kazakhstan, Central Asia" and dated May 2008, a copy of which can be obtained from SEDAR at www.sedar.com.

3. No upper cut grade has been applied to assay data during calculation of average interval grades.

4. Matthew Boyes, BSc, Mineral Resources Manager for Orsu and a "qualified person" as such term is defined in National Instrument 43-101 and for the purposes of the AIM Guidance Note for Mining, Oil & Gas Companies, has reviewed the contents of this press release. Mr Boyes has verified the data disclosed in this release, including sampling, analytical and test data underlying the information.
