Orsu Provides Update on Mineral Exploration Projects in Kyrgyzstan

21 July, 2010

Orsu Metals Corporation ("Orsu", or the "Company") (TSX:OSU, AIM:OSU) provides an update of on-going work at the Talas and Tokhtazan exploration licence areas of north west Kyrgyzstan.

Talas Update

A metallurgical study was conducted at the Dawson Metallurgical Laboratories (which is independent of Orsu), Salt Lake City, Utah, United States. The works were performed on ten (10) initial composites and four (4) additional composites made from 2 metre interval core samples from the Taldybulak prospect.

The initial ten (10) composites consisted of two (2) oxide and eight (8) sulphide samples. The composites also represented different copper ore types with high or low grades of gold or molybdenum. Characterization test work on each of the ten (10) initial composites was conducted at a target primary grind of 80% passing 75 microns and included the following procedures:

Bond ball mill work index tests
Whole ore acid (H2SO4) leaching
Whole ore cyanide leaching
Bulk sulphide rougher flotation tests
Selected composite rougher concentrate re-grind & 3 stage cleaner tests

In the ten (10) initial composites copper grade averaged 0.256% Cu, the average gold grade was 1.1 g/t Au and the average molybdenum grade was 0.013% Mo. Liberated gold grains were observed in seven (7) of the ten (10) composites at a grind size of P80=75 microns. The predominant oxide copper mineral was malachite; the predominant sulphide copper mineral was chalcopyrite with some bornite. Fine (<34 microns) sulphide locking with gangue was observed in most composites. The ten initial composites were low in platinum (0.041 g/t Pt) and low in arsenic (0.003% As).

Four (4) additional composites were made up of sulphide (primary) material and graded 0.19% Cu, 0.465 g/t Au and 0.015% Mo. Sulphide copper mineral was primarily chalcopyrite with some bornite and some fine (<34 microns) grained copper minerals locked in the silica gangue. The four (4) additional composites were also low in platinum (0.004 g/t Pt) and low in arsenic (<0.002% As).

Characterization test work on the four (4) additional sulphide composites included:

Bond ball work index tests
Whole ore NaCN leach tests
Bulk sulphide rougher flotation tests
