	July 17, 2007 East Asia Minerals Expands Sangihe and Tangse Targets
	For Immediate release, July 17, 2007 TSXV: EAS VANCOUVER, B.C. -- Tuesday, July 17, 2007 -- East Asia Minerals Corporation (TSXV-EAS) reports results from its initial exploration at its Sangihe and Tangse projects in Indonesia. At both projects, historic mineralized zones have been verified and expanded. Drilling is scheduled to begin late July at Sangihe followed by drilling of the Aceh projects, including Tangse. Sangihe Interpretation of EAS data compilation together with results of ongoing mapping indicates the additional potential for extending the current Binebase -- Bawone gold mineralization zones towards the northern and northwestern portion of the prospect. On a district scale the Binebase -- Salurang structural corridor hosts multiple, similar discrete gold -- silver mineralized zones that appear to be of the same style and orientation as the Bawone Prospect. This corridor connects the existing Binebase, Bawone and Salurang mineralized zones covering an area of approximately 3 kilometres long by 600 metres wide. Historic drill results at Bawone include 91.3 metres (29.2m to 120.5m) with 2.45g/t gold, 0.42% copper and 12.0g/t silver, and 20.2 metres (21.8m to 42.0m) with 3.97g/t gold, 0.47% copper and 21.0g/t silver (April 12, 2007 news release). A total of 150 rock channel samples from newly discovered mineralized outcrops and verification samples from rehabilitated previous worker's trenching were collected and assayed. This recently completed EAS sampling has verified the previously reported historic surface results in the Binebase-Bawone-Salurang corridor, and extended the mineralized zone along strike. Highlights from the extensions to known mineralisation include 2 metres with 2.90g/t Au & 10g/t Ag from a new exposure approximately 400 meters north of Bawone and 5 metres with 2.93g/t Au & 35g/t Ag including 3 metres with 4.03g/t Au & 53g/t Ag from the Bonsos area located 200 metres southwest of Bawone. These results provide additional evidence that the Binebase - Bawone mineralized zones may be continuous and more extensive than previously thought. Additionally, the sampling has highlighted the potential of other untested or only partially tested zones. Included amongst the areas of interest is the Brown Sugar Zone, an area of historical high grade gold and silver. Here EAS samples returned channel sample assays of 2 metres with 12.8g/t Au and 142g/t Ag; 4 metres with 16.0g/t Au and 196g/t Ag and 1.8 metres with 17.9g/t Au & 251g/t Ag. The extent of this high grade structure is unknown. At the previously untested Sede prospect area, 7km south of the Binebase-Bawone, 3 chip samples returned 5.86 g/t Au and 10g/t Ag, 2.23 g/t Au and 8 g/t Ag and 37.3 g/t Au and 28 g/t Ag. Commenting on the recent sampling the Sangihe Property, Michael Hawkins, President of East Asia Minerals said "We are very excited that not only does this sampling of previous and new trenches provide evidence of improved grades to already strong gold results, but also that there is clear indication the mineralization continues well beyond the areas of historic drilling and trenching. In fact, the new zone of discovered mineralization adds strength to the interpretation the Bawone and Binebase zones may be connected." A Phase One drill program to confirm the Bawone mineralization and strike extension potential will begin at the end of July. The proposed EAS drill program will test for bulk tonnage, gold -- silver targets in addition to the primary, high grade gold -- silver -- copper structural feeder zones. Tangse At the Tangse porphyry copper project EAS field crews have mapped and sampled the area where Rio Tinto identified supergene copper mineralization in the early 1990s. The work has distinguished younger fine grained diorite dykes clearly related to the main quartz diorite porphyry. These dykes are widespread and are interpreted to represent apophyses of larger mineralized intrusive bodies at depth. A total of 672 samples have been collected and analyzed. The best results were found within a northwest trending, 300-metre wide fault zone on the east side of the Tangse target. In general quartz diorite dykes assayed between 0.2 to 0.8% copper. Several plus 1% copper grades, including 2 metres with 2.65% Cu, 2 metres with 2.15% Cu, 2.6 metres with 4.86% Cu and 2.5 metres with 2.85% Cu, were obtained from supergene enriched zones, and a 30 metre composite chip sample of one exposure returned 2.85% Cu. Two to three metre rock channel samples taken from leached and oxidized rock adjacent to the dikes typically assayed 0.04 to 0.1% copper, 40 to 200 ppm molybdenum and 0.1g/t gold. Historic Rio Tinto drilling located 200 to 400 metres east of the EAS identified high-grade copper zone intersected 16 to 27 metres of supergene copper enriched material. EAS will drill test this expanded supergene copper target later this year. Previous limited drilling by Rio Tinto also outlined a large porphyry copper-molybdenum deposit with historical order of magnitude estimates (non-NI 43-101 compliant) of at least 600 million tonnes (Mt) of lower grade material, including a higher grade zone of 30 Mt with grades between 0.3 and 0.8% Cu, and 0.02 to 0.03% Mo (May 1, 2007 news release). The Tangse porphyry system has been subjected to widespread supergene enrichment where the current work is focused. Samples reported were assayed at PT SGS Indoassay assay laboratories.
