East Asia Minerals Extends High-Grade South Miwah Bluff Gold Discovery

| | For Immediate release, July 28, 2009 TSXV: EAS
VANCOUVER, B.C. -- Tuesday, July 28, 2009 -- East Asia Minerals Corporation (TSXV-EAS) reports that mapping/sampling along the recently discovered South Miwah Bluff Gold Zone at the Company's flagship Miwah Gold Project in Aceh Province, Northern Sumatra, continues to extend the strike length of the high-grade gold-bearing feeder structures. Recent rock sawn and chip channel sampling along strike from previously announced areas (news releases of June 3 and July 7, 2009) encountered up to 24.7 g/t gold over 6.3 metres in a rock sawn channel. The Company also announces that drilling is progressing well to test along the full strike length of the main Miwah Gold Zone, with initial assays anticipated over the next weeks. This campaign will now include scout drilling of the new South Miwah Bluff Gold Zone.
Results have been received for an additional 112 rock sawn and chip channel samples from South Miwah Bluff. These include 24.73 g/t gold over 6.3 metres, 20.05 g/t gold over 2.2 metres, 6.15 g/t gold over 3.1 metres and 5.19 g/t gold over 2.0 metres from rock sawn channel samples extending the recently reported high-grade structure (83.59 g/t gold over 24 metres) another 75 metres to the south.
In an area 250 metres south along strike from all previously reported mapping/sampling, the Company encountered 2.2 g/t gold over 24 metres (including 7.89 g/t gold over 5 metres) and 2.78 g/t gold over 15 metres from rock chip channel sampling in an altered subcrop and boulder area.
Twenty-seven chip samples of altered subcrop and boulder were collected in a 135 x 35 metres area located 100 metres north along strike of the 83.59 g/t gold over 24 metres channel sample. . Two clusters of greater than 1g/t gold occur on the southern and northern margins of this anomalous area. Values from the southern cluster include 1.36, 1.42 and 4.72 g/t gold; and from the northern cluster include 1.08, 1.84, 1.91, 2.38, 3.22, 3.71 and 10.3 g/t gold.
These new results combined with ongoing mapping indicate the South Miwah Bluff Gold Zone comprises a minimum of three major generally northerly trending gold feeder structures, with associated cross-cutting structures where high-grade gold appears to be concentrating. The gold-bearing zone has been extended another 250 metres to the south, for a currently outlined north-south length of approximately 650 metres. The north limit is defined as the location where the structures enter the western portion of the higher elevation Main Miwah Gold Zone. The gold structures continue north through the Main Miwah Gold Zone and towards the Sipopok discovery located a further 1.5 kilometres to the north along structural strike. The known width of the South Miwah Bluff Gold Zone, as exposed at surface, is up to 350 metres wide (east-west). To date 204.8 metres of rock sawn channel samples (typically one-metre length, half HQ core size) have been obtained from the South Miwah Bluff discovery, and average 14.25 g/t gold.
Regional scout traverses are planned to evaluate south of the eastern portion of the main Miwah Gold Zone for similar structures to those controlling the South Miwah Bluff Gold Zone to the west. Additionally, reconnaissance mapping north along strike of the South Miwah Bluff Gold Zone, past the main Miwah Gold Zone, has encountered favourably altered outcrop and subcrop north of the current drilling area, towards the Sipopok discovery.
Miwah Update
The South Miwah Bluff feeder structures occur as south to south-southwesterly extensions to the high-grade structures mapped at the western area of the main Miwah Gold Zone, which is currently being drill tested. At least three (to four) main north to north-northeast trending mineralized/altered structures have been mapped and sampled within a 650
metres long by up to 350 metres wide zone connecting with the main Miwah Gold Zone 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. In addition to outcrop, boulder trails and sub-crop are interpreted to represent detached blocks of underlying outcrop.
Within this zone the originally discovered 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, and for repetition elsewhere in the South Miwah Bluff Gold Zone.
The discovery of South Miwah Bluff has opened up the southwest portion of main Miwah Gold Zone and expanded the potential of this large gold system. In addition to drilling of the main Miwah Gold Zone, the current drill campaign will now include scout drilling of this new high-grade area.
Drilling is progressing well, with the fourth hole (EMD 004) now commenced. 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 east-west extent of the main Miwah gold-bearing silica zone, and an additional 2 scout holes to the south. This program will provide a further indication of the gold resource potential and the framework for 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 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 in an area adjacent to the main Miwah Gold Zone.
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).
Samples reported were assayed at Intertech assay laboratories in Jakarta. Michael Hawkins, M.Sc., MAusIMM, 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.
