East Asia Minerals Intercepts 646 Metres of Gold and Copper in Tengkereng Porphyry System

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Dec. 1, 2008) - East Asia Minerals Corporation (TSX VENTURE:EAS) reports that results from drilling the first hole at Upper Tengkereng confirms the presence of a gold-rich porphyry system within EAS's highly prospective Barisan II Project area, in Aceh, Indonesia. The entire 646.25 metre hole was mineralised averaging 0.39 g/t gold and 0.21% copper (0.68 g/t gold equivalent(i)) and included a significant intersection of 268 metres of 0.57 g/t gold and 0.26% copper (0.92 g/t gold equivalent) from 318 to 586 metres. Significant near surface gold mineralisation was also intercepted, including 14 to 82 metres (68 metres) of 0.51 g/t gold and 0.21% copper (0.80 g/t gold equivalent).

"We are particularly encouraged by the results we have received from the first drill hole in our porphyry program," commented Michael Hawkins, President and CEO of East Asia Minerals Corporation. "Our results represent a significant increase in grade over the historical results. This may be due to the gold grades in previous work being understated, or alternatively, a vectoring in the system toward higher gold-copper grades. Upper Tengkereng was drilled first in our porphyry program because of logistical considerations. Each of the five other known porphyry centres in our portfolio have even better historical results and surface indications than Upper Tengkereng. We are therefore very confident of being able to demonstrate that our porphyry portfolio has great potential to add significant value to EAS. We intend to drill test the other porphyries sometime during 2009."

Upper Tengkereng Drilling Update

Recent diamond core drilling by EAS at Upper Tengkereng has returned primary gold-copper intersections at depth beneath coincident gold-copper surface geochemistry and magnetic anomalies associated with porphyry style alteration. Complete results for drill hole UTD-001A are tabled below:

Barisan Porphyry Geological Setting

East Asia Minerals' Barisan II Project encompasses a cluster of six known porphyry centers within a 6.2 kilometre by 3 kilometre block (view map at www.EAminerals.com). At Upper and Lower Tengkereng Prospect areas two windows of similar porphyry gold-copper mineralisation, located about 1.5 kilometres apart, are exposed through shallow volcanic cover rocks and may be linked at depth.

The EAS gold assay results from Upper Tengkereng are much better than those reported by a previous explorer during the mid-90's, suggesting an upgrading of gold results can also be expected at Lower Tengkereng where historical intersections of 339 metres of 0.47 g/t gold and 0.20% copper were reported. The recent and historical drilling results also suggest that gold and copper grades improve with depth.

Previous work at Tengkereng was conducted by a major company and was stopped for non-technical reasons.

Geological features observed in drill core from Upper Tengkereng confirm that this system shares many features of the world's best gold-rich porphyry copper deposits in the circum-Pacific rim. They include:

a) the association of gold-copper mineralisation with composite porphyry stocks emplaced into coeval andesitic volcanic rocks at shallow levels;

b) association of K-silicate alteration at depth which has undergone partial overprinting with advanced argillic and intermediate argillic assemblages;

c) strong positive correlation between quartz vein density and gold and copper distribution mainly represented by disseminated chalcopyrite and bornite;

d) hydrothermal magnetite associated with quartz veining is common at depth but appears to have been destroyed at higher elevations by later-stage overprinting hydrothermal alteration; and

e) the mineralised system is telescoped in which later stage vuggy, banded epithermal quartz veins overprint early porphyry-style veins.

A recent photogeological interpretation of stereoscopic ASTER and PULSAR satellite images of this region has identified additional porphyry targets attesting to the tremendous prospectivity of this mineralised belt. These targets and the other known porphyry centers will be systematically explored in the future.
