East Asia Minerals Encounters More High Grade Gold in Miwah Trenches Including 22 Metres of 3.86 g/t Gold

VANCOUVER, B.C. -- Wednesday, September 10, 2008 -- East Asia Minerals Corporation (TSXV-EAS) continues to encounter significant gold intercepts from trench sampling at its Miwah Project located in Aceh Province, North Sumatra, Indonesia. These results, including 22 metres of 3.86 g/t gold and 18 metres of 2.86 g/t gold are from the eastern half of the Miwah Bluff area.
Miwah Trenching Update
Additional encouraging assay results have been received from channel sampling in trenches at the Miwah gold-copper Project in the same area as previously reported, known as Miwah Bluff. Rock saw channel sampling focused on the eastern side of Miwah Bluff returned consistently strong gold mineralization, hosted specifically in vuggy silica altered breccias and volcanic rock. A total of 954 rock samples assayed so far from Miwah Bluff average 1.22 g/t gold. Selected un-cut composite trench intervals from recent trenches include:
• 16m of 1.25 g/t Au (Trench 42;
• 11m of 2.40 g/t Au (Trench 48);
• 18m of 2.86 g/t Au (Trench 49);
• 10m of 1.34 g/t Au (Trench 55);
• 22m of 3.86 g/t Au (Trench 74);
• 7m of 5.16 g/t Au (Trench 75).
The Miwah Bluff alteration and mineralization zone measures 300 metres long by 200 metres wide (view map at www.EAminerals.com). Extensive surface channel sampling by EAS and a previous explorer shows that this mineralization occurs within a well defined zone of high sulphidation alteration extending over an area measuring 1000 metres by 1000 metres. Better gold mineralization is closely related to a well-defined body of residual vuggy silica-sulphide forming an impressive resistant, east-northeast trending cliff of massive (vuggy) silica traced for over 1000 metres along strike by over 300 metres wide and up to 200 metres high.
Miwah demonstrates many features of the shallow part of a high-level high sulphidation ("HS") epithermal gold system, including intense acid leaching, strong structural and lithological permeability controls to fracture fed mineralizing fluids, presence of structurally-controlled hydrothermal and phreatic breccias, disseminated mineralization of Au-Ag >> Cu and the elemental association of As, Sb, Bi, Ba, S and Te.
The Miwah Property is in a very similar volcanic setting to the Martabe gold-silver deposit, also located in North Sumatra (Purnama and Baskara resources: 127.8 million tonnes at 1.4 g/t Au (5.5 million ounces gold) and 15 g/t Ag (60 million ounces silver), and the alteration system is of a comparable size. In addition to similarities to Martabe, the Miwah project also exhibits a likeness to the size, style and geometry of the alteration system developed at another important HS gold deposit, the Pierina gold deposit in Peru (67.7 Mt grading 2.98 g/t Au and 22 g/t Ag, giving a total 6.49 million ounces gold and 47.9 million ounces silver).
Miwah was partially defined by approximately 3000 metres of drilling in eleven holes by a previous explorer in 1997. All holes drilled during this program intersected significant alteration and mineralization with intercepts including 71 metres at 1.4 g/t gold and 58 metres at 1.1 g/t gold. The previous explorer suggested potential for 100 Mt at 1.1 to 1.2 g/t gold, however a review of the historical data indicates that early drilling was clearly parallel to higher grade (greater than 5 g/t gold) structures at surface, and hence significantly higher overall grades are anticipated from better oriented drill holes.
Integration of recent encouraging trench results and historical work, combined with ongoing detailed surface mapping and sampling will form the basis for selecting optimum drill targets which are anticipated to be drill tested later in the year.
Samples reported were assayed at Intertech assay laboratories in Jakarta. David Royle, B.Sc. (Hons), FAusIMM, CP, the designated QP within the meaning of 43-101, has reviewed and approves the content of this release. East Asia has not verified the classification of the resource references and is not treating them as NI 43-101 defined resources verified by a QP. Although the references of resources are relevant to recognizing the potential of the Miwah project, they should not be relied upon.
