 Drilling confirms multiple new gold targets at Side Well
Key Points
  • Significant result of 4m @ 11.55g/t Au from 40m in 25SWAC286, 4km north of Ironbark
  • Drilling extended Eaglehawk deposit by 500m, now over 1.5km of strike
  • Multiple other anomalous gold and pathfinder element results to be followed up
Full Summary

Great Boulder Resources has provided an update on progress at its flagship Side Well Gold Project, which hosts a Mineral Resource of 668,000oz @ 2.8 g/t Au. The first phase of regional air-core drilling tested several prospective areas never previously drilled, including geophysical anomalies and areas north of the high-grade Eaglehawk deposit. The highlight was an intersection of 4m @ 11.55g/t Au on a geophysical target about 4km north of Ironbark, which is a very high-grade result for air-core drilling. Follow-up holes have been drilled around this intersection, with assays expected in November. The drilling has also extended the Eaglehawk deposit by at least 500m to the north, with a best result of 8m @ 0.67g/t Au from 56m, including 4m @ 1.19g/t Au. Several other gold and pathfinder element anomalies were identified and will be followed up in ongoing drilling programs. A diamond rig has commenced the first deep hole at Eaglehawk as part of Great Boulder's co-funded EIS program, and Phase 3 regional air-core drilling is now underway.

Outlook

The Company is planning to follow up the new gold targets identified through the regional air-core drilling, as well as continue testing the extensions to the Eaglehawk deposit. Further drilling programs are expected to provide consistent, material newsflow.
