INDONESIA - On track for Miwah estimate
The NI43-101 resource drilling program at East Asia Minerals' Miwah Main Zone in Aceh Province, Northern Sumatra, continues to demonstrate a robust gold system and remains on schedule with four diamond drill machines turning.
Completion of the initial resource estimate is planned for March or April, following which exploration drilling will continue in order to expand on the initial resource.
One hole was stopped at 350.9 metres and encountered 9 metres @ 0.59 grams/tonne gold from 207 metres and 11 metres @ 0.35 grams/tonne from 257 metres. Another was completed at 406.1 metres and encountered 29 metres @ 0.47 grams/tonne from 102.2 metres and 24 metres @ 0.34 grams/tonne from 153.5 metres.
A third hole was completed at 205.1 metres and encountered 10 metres @ 0.55 grams/tonne gold from 112, 18 metres @ 0.34 grams/tonne from 159 metres and 6.1 metres @ 0.83 grams/tonne from 199 metres. Another was completed at 352 metres and encountered several isolated favourable alteration/mineralization units from 11 to 104 metres, followed by the main gold bearing horizon from 132 to 352 metres where the hole ended in mineralization due to drill rig limitations.
Another hole at the northeast extreme of the outcropping Miwah Main Zone ended at 200.1 metres and encountered 55 metres @ 0.77 grams/tonne gold, including 16 metres @ 1.15 grams/tonne from 2 metres and 14 metres @ 1.18 grams/tonne from 43 metres. Another in the southeast extreme was completed at 200.2 metres and encountered favourable alteration/mineralization from surface to 11.3 metres, 38 to 41 metres, 45 to 67 metres, and variably between 100 and 150 metres.
A hole drilled east-southeast of the known main zone was completed at 167.1 metres and encountered 29 metres @ 0.26 grams/tonne from 9 metres and 12 metres @ 0.36 grams/tonne from 69 metres, indicating favourable mineralization east from the current resource estimate block.
East Asia has diamond drill validated the 1.2km east-west outcropping width of the shallow, laterally extensive Miwah Main Zone, and has encountered significant gold mineralization in more than 95% of all holes analysed to date. The Miwah Main Zone remains open in all
directions with the Moon River area expanding the north-south potential to more than 600 metres, whilst remaining open further to the north towards Sipopok.
Sampling west of the Miwah Main Zone in the Signal area has potentially expanded the east-west width another 600 metres and remains open.
