East Asia Minerals Reports Indonesia Exploration Progress and Extensions to Gold and Copper Mineralization Tue Sep 18, 7:36 AM Email Story IM Story Printable View VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 18, 2007) - East Asia Minerals Corporation (TSX VENTURE: EAS.V) is pleased to provide an update to exploration activities at its Indonesian projects, and report that encouraging gold and copper mineralization continues to be discovered. Sangihe Project - North Sulawesi Channel sampling in new trenches at the Brown Sugar Zone (in addition to the 7.8 metres of 15.6 g/t gold and 195 g/t silver reported August 30, 2007) has further extended the mineralization with 12.0 metres of 2.45 g/t gold including 4.0 metres of 5.20 g/t gold, and 10.0 metres of 2.65 g/t gold including 2.0 metres of 9.89 g/t gold. The mineralization occurs in barite - quartz breccia. To the north at the Binebase prospect, Trench BIT-2 returned 35.0 metres of 1.12g/t gold. The Sangihe channel samples greater than 0.5 g/t gold have been tested for cyanide leach recoveries. A comparison of gold in fire assay and gold in cyanide leach are very encouraging. Preliminary cyanide leach tests of the Bawone samples have returned a 91.2% to 92.4% gold recovery for oxide and partial oxide material. Binebase samples have an 85.3% to 94.7% recovery with the extraction rate being for lower grade gold material. The Company also reports that Sangihe drilling is progressing well and is intercepting mineralized and altered rock similar to that reported in historical drill holes. Two EAS holes have been completed to date, with assays pending. EAS hole BOD 1, a twin of historical hole BS-18, was drilled to 145 metres. It intersected a silica-barite breccia zone with pervasive to massive sulphide mineralization from 29.2 to 75.0 metres, and a moderate to strong sulphide zone with silica-barite stockworks from 75.0 to 133.0 metres. Hole BOD 2 was drilled to 85 metres and tested a historical high grade zone (20.2 metres of 3.99 g/t gold and 21 g/t silver) reported in hole BS-07, a nearby historical hole. It intersected 22.0 metres of intense vuggy silica-sulphide-barite breccia from 50.0 to 72.0 metres. Aceh Projects Abong Prospect - Barisan 1 Property - Detailed historic exploration data for the Abong sediment-hosted gold prospect, previously worked by North Limited and Rio Tinto, has been purchased and reviewed. In addition to East Asia results, the historic data identifies five mineralized zones. The best of these is the Sarah zone, with historic channel sample results including 16.0 metres of 3.84 g/t gold, 20.0 metres of 2.04 g/t gold, and 16.0 metres of 3.68 g/t gold. At the Narara 1 prospect, historic grab samples are reported with "bonanza" epithermal gold grades, some with visible gold in hand specimen. These include 16.87g/t gold, 129.0g/t gold, 22.6g/t gold, 21.5g/t gold and 54.9g/t gold. Preliminary rock chip sampling by East Asia has encountered grades as high as 3.52 g/t gold and 29.0 g/t silver (August 30, 2007 news release). Review of the historic data supports the previous East Asia observations that the limited past drilling did not properly test the gold anomalous surface samples. This appears to be due to the limited understanding of the structural controls to the surface mineralization (i.e. testing high grade zone away from mapped feeder structures), and the program being terminated prematurely in 1998 due to non-technical reasons. Miwah Project - At the Miwah epithermal gold-copper Project, previously worked by Highlands Gold, ninety-one rock channel and grab samples were collected by East Asia from a vuggy silica and massive silica-alunite-clay breccia. Results include 6.0 metres of 3.63 g/t gold, 6.5 metres of 2.66 g/t gold, 30.0 metres of 1.12g/t gold, and 12.0 metres of 1.33g/t gold. The breccia zone hosting these gold rich samples is 600 metres by 250 metres in extent, and is essentially untested by drilling (three shallow holes at the south extreme). Elsewhere on the property ongoing exploration is focused on improving the definition of higher grade gold in structures that are perpendicular to the historic drilling where grades outside the structures include 71.0 metres at 1.4 g/t gold and 58.0 metres at 1.1 g/t gold. Upper Tengkereng - Barisan 2 Project - Ongoing exploration activities at the Upper Tengkereng gold-copper porphyry Project are defining a series of north to northeast trending dilation features that contain the better copper values. Better gold grades are found in an east-west fault that dissects the porphyry mineralization and includes 15.0 metres of 0.51g/t gold and 35.0 metres of 0.76g/t gold, including 5.0 metres of 1.27g/t gold. Thus far, the Upper Tengkereng prospect is defined for approximately 600 metres long by 400 metres wide, confirming past Rio Tinto work. Tangse Project - At the Tangse copper-molybdenum porphyry project, previously worked by Rio Tinto, ongoing exploration has extended the supergene malachite-chalcocite mineralization for 150 metres northeast along strike from the discovery outcrop (30 metre composite chip sample with 2.85% Cu; July 17, 2007 news release). The malachite-chalcocite mineralization extends into the feldspar diorite porphyry where hypogene chalcopyrite-bornite-chalcocite mineralization occurs as fracture fill in dykes. The dykes are interpreted to represent apophyses of a larger, mineralized body at depth. Takengon Project - Current exploration work is focused on semi-regional follow-up of stream and rock chip sampling anomalies, defined by past Minorco exploration. Recently reported highlights include 5 metres at 3.37 g/t gold and 5 metres at 1.81 g/t gold (August 30, 2007 news release). Samples reported were assayed at PT SGS Indoassay assay laboratories.
