VANCOUVER, BRITISH COLUMBIA--(Marketwire - Jan. 17, 2011) - East Asia Minerals Corporation (TSX VENTURE:EAS) announces results from its second diamond drill hole at the Upper Tengkereng project, supporting the potential for a large and well-mineralized porphyry system and displaying characteristics of some of the world's more important gold-copper deposits. Upper Tengkereng is one of six gold-copper porphyry projects being advanced within the Company's highly prospective Barisan porphyry belt, Aceh Province, Indonesia. Drill hole UTD002 expands on the significant gold and copper porphyry mineralization intersected by the Company's previous and first hole at Upper Tengkereng. UTD002 encountered 0.39 g/t gold, 0.30% copper over the full 690.9 metres length of hole, including 0.36 g/t gold, 0.71% copper over 90 metres in the upper portion of the hole, and 1.17 g/t gold, 0.48% copper over 58.9 metres at the end of hole. The hole was stopped at 696.9 metres in high-grade mineralization due to excessive drill hole cave-in. The drill rig is being moved to the Company's Upper Ise-Ise gold-copper porphyry project located approximately 3 kilometres northeast of the Upper Tengkereng target area.

UTD002 was drilled with a 50 degree azimuth and 60 degree dip to test east of previous hole UTD001A (news release December 1, 2008) where recently mapped 5 to 10% quartz stockwork veining by volume, within advanced argillic alteration and coincident gold-copper surface geochemistry, indicates an improvement in mineralization. The presence of marbleized limestone further east suggests potential for a porphyry heat source at depth. UTD002 was cemented to support the poor ground conditions between 427 and 479 metres, however, it was ultimately stopped at 696.9 metres due to repeated blockage in clay and collapsed cement fragments. The Company notes it encountered similar difficulties and lost drill string with previous hole UTD001A.

The host rock is diorite porphyry. From surface to 120 metres the alteration is predominantly argillic, followed by QIP (quartz-illite-pyrite) to 378.6 metres. From 378.6 to 515.5 the porphyry is a mixture of phyllic and argillic altered intervals, followed by a predominance of phyllic alteration from 515.5 to 696.9 metres (end of hole). A post-mineral dyke was intersected from 596 to 636 metres (40 metres).

Quartz vein density is significant throughout and typically ranges from 5% to 30%. Increased sulphide content correlates well with increased quartz vein density. The sulphide minerals generally occur both within the quartz veins, as vug infill, and disseminated throughout the wall rock, and are frequently in the range of 0.2 to 0.7% chalcopyrite, 0.3 to 0.6% covellite, trace to 0.5% chalcocite, and 5 to 10% pyrite.

* The copper equivalent uses a gold to copper ratio of 1:0.585 (1 gm gold = 0.585% copper); based on long-term prices of $2.25 per pound copper and $900 per ounce gold, assuming total recoveries of both metals.

As a grade comparison the Company notes that the Batu Hijau deposit in Indonesia contains 914 million tons of ore at an average grade of 0.40 g/t gold (366 tons gold) and 0.53% copper (4.8. million tons copper). In addition to similar gold grades as Batua Hijau, the Company also notes analogies to the Chilean Maricunga Belt where some of the best documented porphyry gold and gold-copper systems occur. Gold grades can be exceptional as in the case of Lobo – Marte in the north of the Maricunga Belt, ranging to very good in the south at Caspiche (indicated resource of 785MT at 0.57g/t gold, 0.20% copper, and inferred resource of 685MT at 0.45g/t gold, 0.25% copper) where there are similar grades as at Lower and Upper Tengkereng. Of note is that this is a mineralized belt and there is a suggestion that the increase in gold grade has a vector, in the case of Maricunga, to the north. This could also be the case for East Asia Minerals' Barisan Belt where there are gold-rich epithermals to the northwest such as at Abong.

The Company also refers the reader to the news release of December 1, 2008, for the announcement of initial drilling at the Upper Tengkereng project, and news releases of August 10 and September 15, 2010 for drilling of the Lower Tengkereng project, drilled approximately 1.5 kilometres away from Lower Tengkereng. The initial hole at Upper Tengkereng (UTD001A) was drilled due to ease of access and encountered 646.25 metres averaging 0.39 g/t gold and 0.21% copper, including a significant intersection of 268 metres of 0.57 g/t gold and 0.26% copper. Significant near surface gold mineralization was also intercepted, including 14 to 82 metres (68 metres) of 0.51 g/t gold and 0.21% copper.

The Upper and Lower Tengkereng targets occur as two large outcrop areas of similar porphyry gold-copper mineralization. The Company believes Upper and Lower Tengkereng are possibly contiguous, and part of one large system linked at depth, with the intervening area covered by shallow inter-bedded sedimentary and volcanic rocks.

Barisan Porphyry Geological Setting
East Asia Minerals' Barisan tenements encompass a cluster of six known porphyry centres within a 6.2 kilometre by 3 kilometre block (view map at Geological features observed in drill core from Lower and 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:

  1. the association of gold-copper mineralization with composite porphyry stocks emplaced into coeval andesitic volcanic rocks at shallow levels;
  2. association of K-silicate alteration at depth which has undergone partial overprinting with advanced argillic and intermediate argillic assemblages;
  3. strong positive correlation between quartz vein density and gold and copper distribution mainly represented by disseminated chalcopyrite and bornite;
  4. 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;
  5. the mineralized system is telescoped in which later stage vuggy, banded epithermal quartz veins overprint early porphyry-style veins.

Photogeological interpretation of stereoscopic ASTER and PULSAR satellite images of this region has identified additional porphyry targets, demonstrating the high prospectivity of this mineralized belt. These targets and the other known porphyry centers will be systematically explored.
