East Asia Minerals Updates High-Grade South Miwah Bluff Gold Discovery; 83.59 g/t Gold Over 24 Metres in Rock Sawn Channel Sampling

VANCOUVER, BRITISH COLUMBIA--(Marketwire - July 7, 2009) - East Asia Minerals Corporation (TSX VENTURE:EAS) reports that ongoing exploration of the recently discovered South Miwah Bluff Gold Zone has exposed additional high-grade gold, and continues to expand the Company's flagship Miwah Gold Project in Aceh Province, Northern Sumatra. The Company also announces that drilling is underway to test the full strike length of the main Miwah Gold Zone, having commenced at the western extreme.

Results have been received for 154 rock sawn channel samples from South Miwah Bluff, and include 83.59 g/t gold over 24 metres, 20.14 g/t gold over 12 metres, and 9.21 g/t gold over 7 metres. Detailed follow-up is ongoing to the north and south along strike of the high-grade exposure where several gold-rich channels including 125.9 g/t gold over 23 metres and 19.15 g/t gold over 8 metres were recently discovered by EAS (news release June 3, 2009). These efforts are designed to establish the connection between the main Miwah Gold Zone and this new discovery, and to determine the mineralization boundaries. Additional coherent and detached altered / mineralized bodies have been outlined between the main Miwah Gold Zone and the new high-grade gold discovery.

Miwah Update

Simultaneous to the drill program, geological teams are continuing with sampling of the main Miwah Gold Zone, regionally in areas such as the highly prospective Sipopok Gold Zone 1.5 kilometres to the NNE, and in areas where mapping and sampling have defined direct extensions to the Miwah Gold Zone. Assays results from an additional 154 (generally one-metre long, half BQ core size) rock sawn channel samples have been received for the new South Miwah Bluff feeder zone.

The main South Miwah Bluff feeder structure occurs as a southwesterly extension to the high-grade structure mapped at the western area of the Miwah Gold Zone, which is currently being drill tested. At least four main north to northeast trending mineralized/altered boulder trails have been mapped and sampled within a 360 metres long by 240 metres wide zone connecting with the main Miwah mineralization. The full extent is yet to be delineated. Similar to the main Miwah Gold Zone the dominant alteration is vuggy, sugary and massive silica, with moderate to strong oxidization. The boulder trails are interpreted to represent detached blocks of underlying outcrop.

Within this zone the high-grade gold occurs in outcrop covering 100 metres by 280 metres at the structural intersection of two principal trends running north-northeast and east-west. The gold-bearing bodies are more extensive due to vertical and lateral development, with a high likelihood for the lateral component merging to form a continuous mineralized body. Whilst the mineralization remains open to the south, the current program is also investigating a possible extension of the South Miwah Bluff hydrothermal breccia to the north of the main Miwah Gold Zone.

The discovery of South Miwah Bluff has opened up the southwest portion of Miwah Gold Zone and expanded the potential of this large gold system. In addition to drilling of the main Miwah Gold Zone, ongoing exploration will define drill targets within the new discovery for testing during the current program.

Drilling has commenced with the second hole (EMD 002) progressing well. The initial program will comprise 10 holes for a total of 2,000 metres to provide a 3D validation along the currently defined 1,200 metre strike of the Miwah gold-bearing silica zone, exposed along the Miwah ridge and open to the west. This program will provide a further indication of the gold resource potential and the framework for follow-up drilling. Initial drill results from the program are expected late-July/August.

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 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.

Based on the Company's work Miwah is resolving into two components; a large 1,200 metre long, 300 to 400 metre wide, approximately 200 metre thick tabular zone, and vertical feeder zones that are beneath and cut through this. Within the tabular zone East Asia has over 2,000 metres of rock sawn channel samples which average 1.2 g/t gold. However, ongoing sampling verifies the Company's confidence that higher overall gold grades can be achieved due to the presence of multiple high grade rock sawn channel samples throughout the strike, 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. In addition to the tabular zone the Company has begun to characterize some of the feeder zones, with channel samples including 125.9 g/t gold over 23 metres and 19.15 g/t gold over 8 metres. These feeder zones have great potential to develop into substantial tonnages of higher grade gold mineralization.

Miwah demonstrates many features of the shallow part of a high-level high sulphidation epithermal gold system, including intense acid leaching, structural and lithological permeability controls to fracture fed mineralizing fluids, presence of structurally-controlled hydrothermal and phreatic breccias, disseminated mineralization of gold-silver 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).
