East Asia intercepts gold, copper at Aceh prospect
Wednesday, September 15 2010 - 05:53 PM WIB
LTD002A encountered 0.26 g/t gold, 0.11% copper over 499.7 metres, including 0.5 g/t gold, 0.22% copper over 128 metres. The hole was stopped in mineralization at 499.7 metres due to drill rig limitations. A third drill hole at Lower Tengkereng will follow.
"Drilling to date at the Tengkereng project suggests that we are largely on the periphery of a porphyry gold-copper deposit, although we are encountering higher grades outside the effects of the advanced argillic overprint," commented Michael Hawkins, President and CEO of EAS.
LTD002A, completed at 499.7 metres, was drilled with a 125 degree azimuth and 60 degree dip to test east from drill hole LTD001 in which East Asia Minerals encountered 0.39 g/t gold, 0.18% copper over 415.1 metres, including 0.49 g/t gold, 0.22% copper over 279.4 metres.
LTD002A encountered andesite cover rock to 47.7 metres, followed by diorite porphyry to the end of hole. With depth the porphyry alteration generally grades from advanced argillic, to quartz-sericite--illite--pyrite, to phyllic and quartz-sericite-illite-pyrite, and finally to propylitic with structurally controlled phyllic overprint. Quartz veining increases from 2% to 10% with depth to 427 metres, beneath which it averages 1 to 2%.
LTD003 is planned with a 35 degree azimuth and 70 degree dip, and will be drilled from a lower elevation that will in effect provide an additional 100 plus meters of depth penetration beneath LTD001/002A. Based on current data, the gold-copper grade vectors appear to improve beneath LTD001/002A. This hole will commence the week of September 20 following the Lebaran holiday season.
Barisan tenements encompass a cluster of six known porphyry centres within a 6.2 kilometre by 3 kilometre block.
EAS-TSXV is an Asian-based, Canadian mineral exploration company with gold and copper exploration properties in Indonesia, and uranium exploration properties in Mongolia. In Indonesia the Company has a 70 to 85% interest in six advanced gold and gold-copper properties located in Aceh Province, Sumatra, and Sangihe Island, North Sulawesi. Two of these, the Sangihe (Binebase-Bawone) and Barisan 1 (Abong) gold projects, are being advanced to define NI43-101 compliant resources. (alex)
