East Asia Minerals Extends the Miwah Main Zone to the West; Encounters 2.08 g/t Gold Over 49 Metres Within 85.5 Metres Grading 1.73 g/t Gold

VANCOUVER, BRITISH COLUMBIA--(Marketwire - May 25, 2010) - East Asia Minerals Corporation (TSX VENTURE:EAS) announces that drilling has extended gold mineralization further to the west at the Miwah Gold Project in Aceh Province, Northern Sumatra, Indonesia, confirming the extension of the Main Zone under cover. EMD028 encountered 1.73 g/t gold over 85.5 metres, including 2.08 g/t gold over 49 metres in the uppermost level, extending west from section EMD018/019 where up to 4.08 g/t gold over 81 metres, including 9.29 g/t gold over 21 metres was drilled. This extends the drill defined west potential of the Miwah Main Zone by 130 metres.

EMD028 was drilled to test for the extension of alteration and mineralization west of EMD018/019. The hole was completed at 200 metres downhole depth and encountered 1.73 g/t gold from 55.5 to 141 metres, including 2.08 g/t gold from 58 to 107 metres. This is a significant step to the west of the previously drill validated Miwah Main Zone and in an area of strong gold mineralization. Section EMD018/019, located 130 metres to the east, respectively encountered 4.08 g/t gold over 81 metres, including 9.29 g/t gold over 21 metres; and 2.18 g/t gold over 116 metres, including 3.28 g/t gold over 61 metres. The mineralization is open to the west where EMD032 is commencing, and is interpreted to be contiguous towards previous holes drilled to the north, south and east.

EMD027 was drilled with a due south azimuth and 55 degree dip, to confirm thickness and test for gold grade variation in the vuggy silicification between EMD023 and EMD024. It was completed at 200 metres downhole depth. Gold grading 0.62 g/t was encountered over 147 metres (29 to 176 metres), including 1.28 g/t gold over 33 metres (29 to 62 metres). This intersection is within the transitional zone influenced by the Rusa Fault between the high-grade gold in EMD001-003/018/019 and EMD024. The mineralization is open, and is interpreted to be transitionally contiguous towards previous holes drilled to the north, south and northeast.

EMD029 was drilled with a due south azimuth and 60 degree dip to test for the extension of alteration and mineralization from high-grade hole EMD024. It is a 210 metres north step-out from EMD024 and was completed at 350 metres. EMD029 encountered visually altered and mineralized rock from 60.9 to 69.7 metres, 108 to 227 metres, 307.7 to 310.9 metres and 314.5 to end of hole at 350 metres. Several zones within the hole encountered similar mineralization to that hosting high grade gold at surface and at the bottom of EMD024. Assays are pending.

EMD030 was drilled with a 45 degree azimuth and 47 degree dip from the EMD028 location to test for the extension of silicification and mineralization to the north of EMD021. The hole was completed at 210 metres downhole depth. Commencing at 51 metres depth the hole encountered several zones of visually altered and mineralized rock to 201 metres. From 77.3 to 86.3 metres the hole encountered similar mineralization to that hosting high-grade gold assays at surface and at the end of EMD024. Assays are pending.

EMD031 was drilled with a due south azimuth and 30 degree dip from the EMD028/030 location to further test the extension of alteration and mineralization to the west of the Miwah Bluff portion of the Miwah Main Zone. The hole was completed at 200 metres downhole depth and encountered visually altered and mineralized rock from 58 to 102 metres and 120.1 to 124.4 metres. Assays are pending

EMD032 and EMD033 are just commencing. EMD032 is being drilled with a due west azimuth and 55 degree dip to test further west of the Miwah Main Zone from EMD028. EMD033 is testing to the northeast from EMD014/026, using a 030 degree azimuth and 55 degree dip; the target is extension of alteration and mineralization to the northeast of the Block M portion of the Miwah Main Zone, and southwest of Moon River (Refer to drill location map at www.EAminerals.com).

East Asia has drill validated the 1.2 kilometre east-west outcropping width of the shallow, laterally extensive Miwah Main Zone, and has encountered gold mineralization in all of its holes. The Miwah Main Zone remains open in all directions with the Moon River area expanding the north-south potential to more than 600 metres, whilst remaining open further to the north towards Sipopok. Drilling has extended the Miwah Main Zone towards a similar northing as Moon River. Sampling west of the Miwah Main Zone in the Signal area has potentially expanded the east-west width another 600 metres and remains open.

Miwah Background
The Miwah Gold Prospect was partially defined by approximately 3,100 metres of drilling in twelve 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 from the ongoing drill program which is based on increased geological understanding. An example is the intersection of 3.96 g/t gold over 111 metres, including 15.74 g/t gold over 22 metres from East Asia's diamond drill hole EMD024.

Based on the Company's work Miwah is resolving into two components; a large 1,200 metre long, at least 450 metre wide, approximately 200 metre thick tabular zone; and vertical diatreme breccia feeder zones that are beneath and cut through this. At Miwah Gold Zones, East Asia has almost 2,500 metres of rock sawn channel samples which average 2.35 g/t gold. Grade expectations in Main Miwah Gold Zone exceed 1.5 g/t gold. Ongoing sampling verified 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 Main Miwah Gold Zone, and 4.35 g/t gold over 27 metres at the western part. Recent drilling has supported this. In addition to the tabular zone the Company has begun to characterize some of the diatreme breccia feeder zones, with rock sawn channel samples including 83.59 g/t gold over 24 metres and 20.14 g/t gold over 12 metres. Recent drilling has supported this. 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.

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 Intertek assay laboratories in Jakarta. Lionel Martin, P.Geo., 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.
