East Asia Minerals Provides Mongolia Uranium Program Update
VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 09/07/11 -- East Asia Minerals Corporation (TSX VENTURE: EAS) wishes to report on the progress of its 2011 summer drilling campaign at its wholly-owned uranium projects located in Mongolia. The drilling campaign was launched in August with the objectives of (a) meeting annual expenditure requirements to keep the projects in good standing; (b) test previously identified targets at the Enger and Ingenii-Nars projects; and (c) initiate early stage exploration at the Ulaan Nuur, Sevsuul Bulag, Bukht Uul and Unegt prospects.
East Asia Minerals has now completed the proposed summer 2011 drill program at the Enger project. The program consisted of four PCD-DDH (Polycrystalline Pre Collar-Diamond Drilling) holes and six air core holes for a total of 838 metres. All PCD-DDH holes have encountered the targeted uranium-bearing horizons with down-hole radiometrics supporting the geologic model. Samples from the diamond drill core sections of the holes have exhibited excellent recovery and have been sent to the laboratory for further analysis.
The Enger project was discovered in the mid 1980s by government prospecting teams who conducted at least 18 drill holes, which resulted in the delineation of a historical, non-NI43-101 compliant, resource of approximately 400,000 lbs. of U at an average grade of 0.065% U. East Asia Minerals first acquired the Enger project in August 2005 and actively drilled the property in 2006/07 to confirm the presence of this historical uranium mineralization. Key intercepts of the East Asia drilling campaigns of 2006/2007 included 2.5 metres of 0.410% U3O8 (ENDD003) and 13.5 metres of 0.108% U3O8 (ENDD005). In addition, the drilling supported the concept that the volcanic-hosted mineralization at Enger forms in a similar geological environment to that of the Gurvanbulag uranium deposit (Saddle Hills project) in northeast Mongolia.

For the PCD-DDH program, four holes (ENDD010, and ENDD016 to 018) ranging from 57 to 250 metres depth were drilled to test the southwest up-dip extension of the main mineralization, and up-dip extension of deeper mineralized horizons. All holes encountered the targeted uranium-bearing horizons with down-hole radiometrics supporting the geologic model. The shallower main mineralized horizons at the contact between volcanics and overlying sediments were successfully extended. In addition, a number of tabular or lens like zones were encountered within altered rhyolite and associated tuffs just beneath the contact zone. The southwest extension from deeper zones was encountered in the eastern area of drilling, whereas to the west there appears to be some cut-offs or off-setting due to faulting. The 2011 program has extended the Enger deposit up-dip to the southwest and remains open in all other directions.
For the air core drilling (EN01AC to EN06AC), two prospective areas were identified in the northeast sector of the property from a soil gas hydrocarbon geochemical survey and follow-up ground radiometric survey. East Asia drilled six shallow holes (20 to 54 metres depth), with two holes identifying early stage targets for further investigation in sediments. Hole EN001AC encountered an average of 610 cps (counts per second) from 1.8 to 3.5 metres depth, and drill hole EN005AC encountered 373 cps from 10.17 to 10.42 metres.
The following table presents the key drill intercepts from holes conducted by East Asia Minerals since acquiring the project in 2005. By comparing the cps readings with assay results of the 2006/07 drill programs, East Asia Minerals is encouraged by the results of the 2011 drill program. The 2011 cps results are indicative and validation will be determined when assays are received from the submitted core samples.

The drill rig at the Enger project has now been moved to the Ingenii-Nars project. The proposed drilling program at Ingenii-Nars is expected to include four PCD holes in the main zone of the sandstone-hosted uranium project. Additional drilling in other parts of the property had been planned and is now being reconsidered in light of this year's excessive wet conditions in the clay basin where the project is located.
EAS has not verified the classification of the historic resource reference and is not treating it as a NI 43-101 defined resource verified by a QP. Although this historical resource is relevant to recognizing the potential of the Enger Property, it should not be relied upon. Samples have been sent to Stewart Mongolia LLC Laboratory in Ulaanbaatar, Mongolia. Lionel Martin, P.Geo., the designated QP within the meaning of NI 43-101, has reviewed and approves the content of this release.
