East Asia Minerals Identifies High Grade Exotic Copper Oxide at Khok Adar

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Aug. 25, 2005) - East Asia Minerals Corporation, (TSX VENTURE:EAS) announces that the high grade copper oxide mineralization identified at the Khok Adar project located in western Mongolia is part of an exotic copper deposit. Exotic copper deposits typically form within 7 kilometres of high grade supergene enriched copper (chalcocite) sources, the best examples of which are associated with several of the world class Chilean copper deposits.

Geologic evaluation of mapping, trenching, and drill results from last and this year's exploration indicates the copper mineralization intersected is of two distinct secondary types, separated by a north 15 degrees east trending structure. Exotic copper oxides (predominantly as azurite, malachite, cuprite, tenorite, chrysocolla and native copper) were deposited within fractures and pore spaces of brecciated quartzites west of this structure. On the east side in Zone 1 as previously defined by Soviet exploration work, there is chalcocite enrichment which occurs in the mixed sulphide/oxide zone. For example, hole KA-04-04 (reported on May 10, 2005) intercepted 23 metres which contained 1.60% copper and a sub-interval of 14 meters containing 2.44% Cu and 59.8 gpt Ag.

"This is an encouraging discovery" remarked Lyndon Bradish, President and CEO of East Asia Minerals. "Both the chalcocite and copper oxide mineralization suggests there must be a high grade copper source elsewhere on the property because there does not appear to be enough chalcopyrite in Zone 1 where it has been drill tested to have produced the enrichment blanket. The inferred supergene enriched copper source for the exotic copper represents an important priority target in addition to other exotic copper mineralization that may be discovered within the 2 kilometres of geochemical anomaly".

The Phase II trenching and drilling program is well underway with 1129 metres of reverse circulation in 10 holes and 1986 metres of diamond core in 11 holes completed as of August 22nd. This year's drilling along strike of Zone 1 has identified supergene chalcocite and covellite mineralization that averages 15 - 20 metres in thickness and 120 - 200 metres in width within the mixed oxide and sulphide zone located below an intensely weathered surface. Assays are pending. Additional assays from Holes KA-04-05 and KA-04-06 have returned significant values and are reported below.

Subsequent to the first shipment of core (as reported above) to McPhar Laboratories in the Philippines, the company had experienced delays in getting samples shipped due to recent changes in Mongolian export requirements for drill core samples. The company has since made alternative assay arrangements using Alex Stewart Labs for sample preparation and SGS Mongolia for assays. The next round of drill core assay results is expected in the first week of September.
