August 30, 2007: East Asia Minerals Extends Sangihe Mineralization and Starts Drilling
Sangihe is a 42,000 hectare advanced exploration property located on Sangihe Island, North Sulawesi Province, which encompasses numerous drill-ready epithermal gold and porphyry copper-gold prospects. Under the terms of the Joint Venture Agreement (JVA), East Asia has a 70% starting equity in the project.
The Company has now received all necessary approvals in principle from the Government, and has been granted a preliminary exploration permit (SIPP) whilst it continues its negotiations for the grant of a Contract of Work (CoW), modelled on a 7+ generation template. Under the SIPP the Company is authorised to conduct all proposed exploration activities, including drilling.
The Sangihe property lies within the Sulawesi-East Mindanao Arc, one of the most productive arcs in Indonesia. This arc hosts the Mesel and Lanut Gold Mines in Sulawesi, and the Tampakan porphyry-epithermal (900Mt at 0.75% Cu, 0.3g/t Au, including 300 Mt at 1.05% Cu, 0.4 g/t Au) and Boyongan porphyry deposits in Mindanao, Philippines. The Sangihe project was explored in the 1980-90s when Ashton Mining (Australia) drilled over 5,000 metres in the Bawone and Binabase epithermal prospects. Historical studies (1998) indicate the potential to discover 1-2 million ounces of gold in this area alone. (EAS has not verified the classification of historic resource references and is not treating it as a NI 43-101 defined resource verified by a QP. Although this historical reference of resource potential is relevant to recognizing the potential of the Sangihe Property, it should not be relied upon.)

Bawone and Binebase are intermediate to high sulphidation epithermal gold prospects located three kilometres apart and probably contiguous in the larger overall system. At Bawone, mineralization is well defined by an IP anomaly that continues beyond the drill tested zone. Historic drilling encountered significant mineralization, open along strike and to depth, including:
Bawone
91.3m (29.2m to 120.5m) with 2.45g/t gold, 0.42% copper & 12.0g/t silver
67.8m (50.3m to 118.1m) with 1.5g/t gold and 0.41% copper
81.9m (38.0m to 119.9m) with 1.3g/t gold and 0.28% copper
20.2m (21.8m to 42.0m) with 3.97g/t gold, 0.47% copper and 21.0g/t silver
Binebase
36.4m with 1.72g/t gold
28.1m with 1.05g/t gold
14.0m with 2.0g/t gold
Other partially tested Sangihe prospects include Kelapa where trenches contain impressive historical results, including: 14m with 34.8g/t gold; 10m with 9.11g/t gold and 6m with 9.19g/t gold.
The mineralization is covered by post-mineral tuffs and drill targets were previously established by IP and magnetics. The defined mineralization is up to 50m wide and is shown by drilling to be continuous for at least 400m strike, and down to at least 100m depth. It is open to the northeast and southwest. The northeast extent in particular holds strong exploration promise, as geophysics indicates that the anomalies continue for at least several kilometres in this direction. There are two outcrops, as windows through the cover, along this extension which returned assays of 9.4g/t Au over 7.5m and 2.3g/t Au over 10m. The geophysical data also indicates the presence of other untested targets parallel to the identified zone.
A field team has been mobilized to the project and environmental baseline studies have already been completed. Planned 2007 drilling at Sangihe will confirm existing mineralization and step out along strike where historical trenching and geophysics, and EAS re-sampling indicate extensions to mineralization. Initial efforts will also include mapping, trenching, further re-sampling, extension of the induced polarization survey and target generation in areas such as Kelapa.
