| East Asia Minerals to Start Drilling at Miwah in Late May |
| VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 20, 2009) - East Asia Minerals Corporation (TSX VENTURE:EAS) reports that diamond drilling on the Company's flagship Miwah Gold Project in Aceh Province, Northern Sumatra, is planned to commence in late May 2009. The initial drill program will comprise 10 scissor holes from five (5) collars for a total of 2,000 metres to provide a 3D validation along the full 1,200 metre strike of the Miwah gold-bearing silica zone, exposed along the impressive Miwah ridge. This program will provide a further indication of the gold resource potential and the framework for follow-up drilling. While over 2,000 metres of rock saw channel samples averaging 1.2 g/t gold have been collected by EAS across the entire system, the Company is confident that higher overall gold grades can be achieved due to the presence of multiple high grade rock saw channel samples including 4.11 g/t gold over 200 metres at the eastern part of the gold zone, and 4.35 g/t gold over 27 metres at the western part (refer to previous news releases). The drilling program will be supported by helicopter using a man-portable rig. Initial drill results from the program are expected in early July with drilling continuing for approximately three months and beyond with follow-up drilling. Miwah Background The Miwah Gold Prospect was partially defined by approximately 3,000 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 of 1.4 g/t gold and 58 metres of 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. Hence, in addition to greater mineralized tonnage, significantly higher overall grades are anticipated from better geological understanding, results of the Company's detailed sampling, and properly oriented drill holes. Rock saw channel sampling by EAS in 2008 within a well defined, one square kilometre zone of high sulphidation alteration averaged 1.2 g/t gold and +3 g/t silver from over 2,000 metres of samples. Better gold mineralization, including 4.11 g/t gold over 200 metres, is closely related to massive, residual vuggy silica-sulphide forming an impressive resistant, east-northeast trending cliff traced 1,200 metres along strike, averaging 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 gold-silver much greater than copper, 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 gold (5.5 million ounces gold) and 15 g/t silver (60 million ounces silver), and the alteration system is of a comparable size. Miwah also exhibits a likeness to the size, style and geometry of the alteration system developed at the Pierina gold deposit in Peru (67.7 Mt grading 2.98 g/t gold and 22 g/t silver, giving a total 6.49 million ounces gold and 47.9 million ounces silver). Samples reported were assayed at Intertech assay laboratories in Jakarta. David Royle, B.Sc. (Hons), FAusIMM, CP, the designated QP within the meaning of NI 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. About East Asia Minerals Corporation East Asia Minerals is an Asian-based, Canadian mineral exploration company with gold and copper exploration properties in Indonesia, and uranium exploration properties in Mongolia. In Indonesia the Company has a 70 to 85% interest in six advanced gold and gold-copper properties located in Aceh Province, Sumatra, and Sangihe Island, North Sulawesi. Two of these, the Sangihe (Binebase-Bawone) and Barisan 1 (Abong) gold projects, are being advanced to define NI43-101 compliant resources. The Company owns twelve uranium properties, including the advanced Ingiin-Nars, Ulaan Nuur and Enger uranium projects, four phosphate properties, and a 75% interest in the Khok Adar copper oxide discovery in Mongolia.
