EMD050 was drilled with a 25 degree azimuth and 55 degree dip to test for continuity of mineralization north-northeast from EMD049. The hole was abandoned early at 159.6 metres due to drilling problems, however, 0.24 g/t gold was intersected from 69 to 105 metres (36 metres), above the targeted Miwah horizon. Additional drilling is planned in this area as part of the NI43-101 resource drilling and infill program, the company said.
EMD051 was drilled with a 45 degree azimuth and 50 degree dip to test for continuity of mineralization east from EMD024. The hole was stopped at 500 metres and encountered gold starting at surface. Assays included 0.61 g/t gold from 0 to 210 metres, including 2.8 g/t gold from 27 to 52 metres (25 metres), and 0.85 g/t gold from 245 to 282 metres (37 metres) including 1.91 g/t gold from 269 to 279 metres (10 metres). Several narrow plus 2 g/t gold intervals were encountered below 282 metres.
EMD052 was drilled with a 215 degree azimuth and 60 degree dip to test for continuity of mineralization west from EMD024 and EXD003. The hole encountered favourable alteration/mineralization from 111.2 to 112.8 metres prior to entering a mixed favourable host from 112.8 to 127.3 metres. The hole re-entered and continued within the favourable Miwah Horizon from 154.9 metres to the end of hole at 350.9 metres where drilling stopped due to drill rig limitations. Assays are pending.
EMD053 is being drilled a due north azimuth and 60 degree dip in the western area of the Miwah Main Zone, as part of the ongoing infill program for the NI43-101 resource estimate. The hole entered favourable alteration/mineralization at 102.2 metres, in which it continued to the current depth of 131.2 metres.
EMD054 is soon to commence, planned with a 45 degree azimuth and 50 degree dip in the western area of the Miwah Main Zone, as part of the ongoing infill program for the NI43-101 resource estimate, it said.
Extension of EXD003 has commenced, continuing from the previously drilled due south azimuth and 55 degree dip. Previous drill hole EXD003 was terminated in high-grade gold mineralization due to drill rig limitations, and encountered 1.31 g/t gold from 174.5 metres to the end of hole at 220.5 metres (46 metres), including 11.78 g/t gold from 217 to 220.5 metres (3.5 metres) where it finished in gold mineralization. This included a 1.25 metre interval of 30.37 g/t gold in the penultimate sample from 218 to 219.25 metres.
EXD005 was drilled with a 75 degree azimuth and 50 degree dip to test the extension of alteration/mineralization to the southeast of EXD004 where recent channel sampling encountered 1.23 g/t gold over 12 metres, including 3.04 g/t gold over 3 metres in the East Block M area. The target is located 400 metres east of drill hole EMD016. EXD005 was completed at 167.1 metres and encountered patchy favourable alteration/mineralization from 0.7 to 58.5 metres, and 69.5 to 92.4 metres. The alteration/mineralization is open in all directions and at depth. Assays are pending.
EXD006 was drilled with a 45 degree azimuth and 50 degree dip to test northeast from EXD003 towards Moon River. The hole was completed at 350 metres after drilling a quartz diorite intrusive from 163 to 242.4 metres. No significant gold assays were returned, attributed to the late quartz diorite intrusive. Of note is that stockwork gypsum and anhydrite are spread over the lower interval from 276 metres to end of hole, suggestive of underlying porphyry.

Two scout holes were drilled at Sipopok to test for continuity of alteration/mineralization to the east and beneath recent rock sawn channel samples that assayed up to 1.26 g/t gold over 4 metres and 0.98 g/t gold over 4 metres.
Sipopok diamond drill hole SPD001 was drilled with a 215 degree azimuth and 65 degree dip, and successfully cross-cut favourable Miwah-type silica and silica-alunite alteration/mineralization. The hole was completed at 200 metres after passing through Miwah-type horizons at 62.5 to 130.3 metres, and 136.4 to 140.4 metres. Assays gave 0.38 g/t gold from 105 to 117 metres (12 metres) including 0.61 g/t gold from 111 to 117 metres.
SPD002 was drilled with a 35 degree azimuth and 50 degree dip to test directly northeast from the favourable Miwah-type horizon encountered in SPD001. The hole was abandoned at 174.4 metres after encountering Miwah-type silica and silica-alunite alteration/mineralization from 40.3 to 60.52 metres. Immediately following this horizon, the hole was dominated by fault breccia and abandoned after several shifts attempted to cement the hole for continuation. Assays are pending. (Refer to drill location map at www.EAminerals.com).
Whilst preparing a drill pad for testing of Sipopok, the scout drill rig was used to complete a short 225 degree azimuth and 60 degree dip hole beneath the high-grade western margin of South Miwah Bluff. SMD001 was completed at 120 metres depth and encountered 0.51 g/t gold from 2.6 to 19.8 metres (17.2 metres), including 0.78 g/t gold from 2.6 to 11 metres (8.4 metres).
East Asia has diamond drill validated the 1.2 kilometre 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 analyzed 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. Drilling has extended the Miwah Main Zone towards a similar northing as Moon River. Sampling west of the Miwah Main Zone in the Signal area has potentially expanded the east-west width another 600 metres and remains open. Recent sampling east of the Miwah Main Zone in the East Block M area has potentially expanded the east-west width another 400 metres and remains open. (denny)
