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.
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.
